Also, mounting turbine engines repositioned the props three inches farther forward. A turbine engine is normally “torque limited” at lower altitudes and “temp limited” at higher altitudes. New parts added daily. Pulled back to 63% (yes, 63%) with 232 gallons in the tanks, Dukes could still manage 195 to 200 knots, endure for 5.5 hours and range out more than 1,000 nm. It’s interesting that the least expensive Royal Turbine’s price makes it far less expensive than the oldest SOCATA TBM-700, a single-engine turboprop. rocketengineering.com Whereas the JetPROP burns 32 gph to obtain 260 KTAS, the Royal Turbine Duke will burn 64 gallons to cruise at 290 KTAS. This website is estimated worth of $ 8.95 and have a daily income of around $ 0.15. I planned a flight from Dallas, TX (DFW) to Nashville, TN (BNA) and found the following results on this 549NM flight (using current weather on the day of writing this article): So, the fuel burn is nearly identical, and the -34/35 arrives 9 minutes earlier. So, today you can only purchase a -21 Conversion or a -35 Conversion from the factory in Spokane. To me, the -21 is just as solid a cross-country machine as the -34/35. The two most important questions are: 1) How much turbine reliability are you willing to pay for? Buyers of a Jetprop value speed and many simply don’t understand buying anything that is “slower”. The swept, stiletto shape was an immediately recognizable winner. So, Rocket Engineering did what they do best…take a great airframe and mount a great engine (PT6) on the front. In other words, start with a $150,000 to $200,000 Duke, buy the Royal Turbine conversion for $887,000, and you could be in a 300-knot, six-seat, twin turboprop for just over $1 million, albeit one fitted with two new engines. Get 96119-01 by Rocket Engineering/Jetprop Llc for aircraft model DLX. “Launched” is the operative term in this case, as the Royal Turbine quickly wound the VSI around to 4,000 fpm at a climb speed of 120 knots. Conrad, Sadler and partner Warren Wood began converting Malibus and Mirages to the P&W PT6A-21 in 1997, and since then, they’ve upgraded an impressive 18% of Piper PA-46s to turbine power. When it does, I get a lot of questions from prospective buyers, most wanting to know if the -21 is “worth owning”. At such spectacular climb rates, it doesn’t take long to reach big altitudes, and we leveled seven minutes after takeoff at 23,000 feet, the airplane’s optimum speed height. Turboprops are here and now, and Conrad’s Royal Turbine effectively brings the reliability and performance of a high-performance turboprop to the piston crowd. So, the -34/35 will comparatively produce more power than the -21 as the altitude is increased, and this results in a better climb rate and faster cruise, but it also results in higher fuel consumption. Effectively, the -21 performs nearly identically to the -34/35 at low altitude. Effectively, the -34 and -35 Conversions provide the same performance, so I will contrast the -34/35 collectively with the -21 in this discussion. Does the additional speed of the -34/35 translate into a meaningful lessening of flight time? Rocket Engineering’s most popular mod is the JetProp DLX conversion of the Piper Malibu and Mirage, which replaces the piston engine with a Pratt & Whitney PT6. The Best Just Got Better! But Rocket Engineering is as healthy a company in GA as they come - knock on wood - because it is a rickety industry subject to whims of the economy, but they are very lively with their piper jet prop conversion. Add the weight of 267 gallons of jet fuel (at 6.7 pounds per gallon), and the Royal Turbine winds up with a payload of 731 pounds, an easy four folks plus baggage. What is “numerical prejudice”? Conrad has been through the STC certification wars many times, and he’s as familiar as anyone can be with the FAA’s requirements. They tend to know what they are looking for and will pounce when they see the right -21 with the right “desirable” characteristics (good maintenance lineage, avionics, paint/interior, useful load). Rocket Engineering’s most popular mod is the JetProp DLX conversion of the Piper Malibu and Mirage, which replaces the piston engine with a Pratt & Whitney PT6. Piper Aircraft themselves saw the … (Conrad lists SESC as 27,000 feet, but even that may be conservative.) With his experience installing and flying the PT6A-21 and -35 in the Malibu Jetprop, he knew the P&W engine was about as bulletproof as they come, rated for 3,600 hours between overhauls and willing to run that long with very little service. Given the lead-time to bring an STC to market, Rocket Engineering & JetProp have a steady stream of new STCs in their pipeline. Okay, the airframe is hardly new, but a million bucks won’t buy you anything like the same performance from a 20-year-old Piper Cheyenne III or a 25-year-old Cessna Conquest II. ROCKET ENGINEERING OF SPOKANE, WASH., says it plans to obtain FAA certification of the Turbine P/Baron in December 2006. Normal multi-engine service ceiling, incidentally, remains the Duke’s original 30,000 feet. Conrad reasoned that things could only get better and more reliable (if more expensive) by replacing the troublesome TIO-541s with P&W turboprops. During takeoff, a turbine pilot will keep a keen eye on the torque gauge, with little care for the ITT knowing that the ITT (temp) will be low (usually, unless there’s an anomaly). Take the Beech Duke, add turbines, and you get that magical number, By Bill Cox, Photography by James Lawrence Updated January 28, 2016 Save Article. - Photo taken at Samedan (St. Moritz) - Oberengadin (SMV / LSZS) in Switzerland on August 31, 2003. Rocket engineering jetprop conversion keyword after analyzing the system lists the list of keywords related and the list of websites with related content, in addition you can see which keywords most interested customers on the this website Where this switch occurs is usually observed by the pilot so he monitors the correct limiting factor. Bottom line forward…I really like the -21 Jetprop Conversion! But, since the -34 is an engine designed for the lower altitudes (originally developed for the helicopter market and crop-duster market), some of the -34 conversions did not perform as-advertised at high altitude (the late Lyn Amestoy, a great salesman at Rocket Engineering who regrettably passed away in an accident in mid-2015, told me that about 10% of the -34’s performed “less than ideally at high altitude”, suffering a slightly lesser cruise speed). Plane and Pilot builds on more than 50 years of serving pilots and owners of aircraft with the goal of empowering our readers to improve their knowledge and enthusiasm for aviation. The JetPROP is an aftermarket turbine engine conversion for the PA-46-310P Malibu and PA-46-350P Malibu Mirage offered by Rocket Engineering of Spokane, WA. Rocket Engineering continues to offer excellent value, and performance, with their Piper Malibu and Malibu Mirage conversions. Get your required aircraft engine mounts 96119-01 parts with competitive pricing. Most buyers don’t understand the differences between the Jetprop variants, but they do know that 35 is a bigger number than 21, and therefore it must be better, right? The Turbine Air initially climbs at 3,000 fpm, has a maximum altitude of 25,000 feet, and consumes 29 gph while cruising at 225 KTAS at FL180. JetPROP and Rocket Engineering, based in Spokane, Washington, have performed 148 conversions (32 of which are from Europe) since receiving certification in 1998. … DLX Originally certified in 1998 as the JetPROP DLX with a Pratt & Whitney PT6A-34 engine, conversions 90 and above used the P&W PT6A-35, after the -34 was … ... they are making all those sweet jetprop conversion). Buyers of the -21 become aware of the lack of any consequential differences in performance and are therefore happy to buy a – 21 if it is available. So, it seems appropriate for me to leap into the gap and post my thoughts on the -21. In order to rebalance the envelope, Conrad relocated both batteries to the nose, as far forward as possible. Enjoy turbine performance with piston economics. To date, Rocket has converted 10 Bonanzas to turbine power in a little over one year of production. As a result, Conrad increased fuel capacity to 267 gallons of heavier jet fuel, reducing the theoretical payload improvement to 153 pounds—still impressive. We launched for the flight levels out of Truckee-Tahoe Airport, in California, on one of those crystal-line, Chamber of Commerce days. A lower cost JetPROP DL conversion became available in October 2003 utilizing the P&W PT6A-21. In case you hadn’t noticed, the Royal Turbine depicted on these pages is a Beech Duke with Pratt & Whitney PT6A turboprops in place of the standard piston, TIO-541 Lycoming engines. But, the -34/35 will burn between 32-33 Gallons Per Hour (GPH) at FL270 and the -21 will burn about 28 GPH at the same altitude. NFlightMic’s product is the best headset on the market, Deanna’s India-to-US Ferry Flight in a King Air C90, -21 = 2’24” burning 76.9 gallons of Jet-A, -34/35 = 2’15” burning 75.8 gallons of Jet-A, -21 = 1’12” burning 43.3 gallons of Jet-A, -34/35 = 1’09” burning 40.5 gallons of Jet-A. Rocket Engineering JetProp DLX (Malibu Mirage version) Conversion cost: $599,000 (plus airframe cost) Specifications; Powerplant: Pratt & Whitney PT 6A-34, 750 shp, flat-rated to 560 shp: Recommended TBO: 4,000 hr: Propeller: Hartzell 4-blade, constant-speed, reversible: Length: 30 ft, 1 in: Height: 11 ft, 3 in: … A bare handful of propjets can touch 300 knots in cruise—the Piper Cheyenne 400LS, Commander 1000, Mitsubishi Solitaire, Beech Starship and King Air 350, and the Socata TBM 700. The airplane’s cruise climb at 175 knots was even more interesting at 2,000 fpm. As no active threats were reported recently by users, rocketengineering.com is SAFE to browse. If that seems a bargain, it is—except for one major problem. In today’s market, good Jetprop’s tend to sell VERY quickly, often never being advertised on Controller or TAP. Without a doubt, the -35 Conversion is the most popular of the conversions offered today. All of these engines perform well at lower altitudes since there’s plenty of available air density, but that changes as altitude is increased. It has attracted customers here in the United States and especially in countries where avgas is prohibitively expensive or simply not available. At the very top of the climb (near FL270), the -34/35 will still be climbing at 800 FPM, and the -21 will eek out 500 FPM. Nevertheless, Duke owners almost unanimously adored their airplanes. Here’s the calculations for a flight from DFW to HOU (Houston, TX) on the same day using the same weather: On this shorter flight, the -21 arrives only 3 minutes later than the -34/35 and burns a comparatively equal amount of fuel. Both PT6As are flat-rated for 550 shp, but the -35 will maintain that power to 21,000 feet while the -21s begin to lose thrust at 16,000 feet. Specs, range, speed, operating weights and performance for the Jetprop DLX here We use cookies to help you get the best experience when using our website. Probably not, but it is reality. The additional horsepower available that was used for the climb is turned into forward speed in cruising flight. Care to join the -21 owners club? Fans of turboprops know Darwin Conrad as the engineer responsible for creating the Malibu Jetprop. The compressor section was deemed the culprit of the lack of power at altitude, so the -35 engine was offered (the -35 is generally the same as the -34 except the -35 has better aerodynamics in the compressor section). The difference with the -35s installed will be better climb at high altitude and about 25 knots more cruise in the middle flight levels. Right up front, the most obvious difference is sheer, brute power. Jetprop conversion is a highly integrated STC-overseen by same certification office (ATL- ACO) Jetprop conversion is not ‘a PT-6 bolted on the front of a Malibu’ Jetprop (Rocket Engineering) enjoys strong customer service reputation ; Serviceability- Jetprop has distinct edge (Battery access, engine accessories access, etc) It is the best equipped Avidyne airplane on todays market. In the early ’70s, new crankshafts, cylinders and other upgrades increased TBO to 1,600, but again, most Duke owners had little chance of reaching TBO. The Royal Turbine is the latest product of the fertile imaginations of Darwin Conrad and Jeanie Sadler of Rocket Engineering in Spokane, Wash. No damage history, no excuse, ready to fly airplane. It won't happen next year or the year after, perhaps noteven for another 20 years, but it'S likely avgas … It won't happen next year or the year after, perhaps noteven for another 20 years, As demand for the Jetprop conversion inevitably began to wane, however, the engineer knew he’d need some new products, and that led to the development of the Turbine Air, a Beech B36TC converted to the same P&W engine. In the grand scheme of things, the ROC is just not a huge deal with either the -34/35 or the -21. In fact, the -34/35 has a STELLAR climb rate throughout the climb, and the -21 has a very acceptable ROC throughout the climb. Rocket Engineering's new TurbineAir ... After that came the groundbreaking conversion for the Malibu. THIS ROCKET ENGINEERING CONVERSION GIVES A B36TC A HUGE BOOST By Bill Cox Photography Byo James Lawrence T'S A REALITY NONE OF US LIKE TO THINK ABOUT, BUT AVGAS IS PROBABLY ON rrs WAY OUT. The engines were so unreliable that many Dukes spent much of their time on the ramp or in the shop. Jetprops, ie piston engine aircraft converted to turbine seem tremendous value for money as far as I can see. Photo of The Week: Our Christmas List: A $72,000 Mach .84 Jet. The Royal Turbine turboprop conversion is the latest of Conrad and Sadler’s brainchildren, and it takes as its foundation an airplane that has long had a following equally as fanatical as that for the Bonanza. Garmin G500 EFIS with Synthetic Vision Technology. Comparatively, the -21 and the -34 will climb from sea level through 12,000 MSL at about the same time since both are “torque limited” through 12,000 MSL…the -34/35 will beat the -21 in most instances, but not significantly. Beech fitted the Duke with a pair of TIO-541 engines, a model that was to prove one of the least reliable in the industry. It is a domain having com extension. This JetProp DLX has great bones! The -21 is certainly the cheapest turbine to acquire/operate, and owners become rightfully passionate. INFORMATION PROVIDED FOR INTRODUCTION ONLY. Equipped with SynVis G500, user-friendly dual Avidyne IFD's, KMD850, upgraded … The -21 was introduced in the early 2000’s as a cheaper option for those that wanted a Jetprop, but were interested in preserving cashflow. Not in my book. A lower cost JetPROP DL conversion became available in October 2003 utilizing the P&W PT6A-21. And, remember…”power is always popular”. As the climb continues, the -34/35 will average about 1,000 FPM ROC through FL230 and the -21 will be at about 700 FPM. There’s is one disadvantage to the -21…the market does not favor the -21. Collectively, these changes offset the lighter engines and restored the balance. Plane and Pilot expands upon the vast base of knowledge and experience from aviation’s most reputable influencers to inspire, educate, entertain and inform. Twenty percent of the entire PA-46 fleet have been converted. It has attracted customers here in the United States and especially in countries where avgas is prohibitively expensive or simply not available. Become a member and get exclusive access to articles, contests and more! Up high with everything trimmed out, the Duke was alleged to be capable of 233 knots, although 215 to 220 knots was probably more realistic, meanwhile pouring 45 gph through the engines. Well, not always. A little history…the -34 was the first Jetprop conversion in the late 1990’s and when it became available it was the best of the best. In 2002, Conrad and Sadler launched into a development program to replace everything from the firewall forward on the prototype Duke. The fuel/air ratio that is burned in a PT6 engine is the same at any altitude. I fly all of the Jetprop variants frequently and I’d CERTAINLY buy a -21 if I were shopping for a Jetprop. It’s a magic number and one not often seen in turboprop corporate aircraft. Predictably, converting a piston airplane to turbine power wasn’t exactly a slam dunk. To answer that question, I turn to www.fltplan.com which has templates for both the -21 and -34/35 conversions (incidentally, I use fltplan.com for all of my flight planning, mainly because they have SUPER-accurate fuel-burn calculations as they use ACTUAL forecast winds in the flight time/fuel burn analysis). As the -34/35 goes through FL180, the average rate of climb (ROC) is about 1,200 FPM; as the -21 goes through FL180, the average ROC will be about 900 FPM. My usual response is, “Absolutely!”  But, as is true with most aircraft purchase decisions, “he with the most information usually wins.”  With three variants of Rocket Engineering’s popular Jetprop Conversion, there seems to be a lot of confusion amongst the uninitiated and the -21 Conversion is certainly the most misunderstood of the Jetprop conversion. So, it seems appropriate for me to leap into the gap and post my thoughts on the -21. -21 Jetprop owners tend to become some of the most vociferous supporters of their purchase decision to own one of these incredible airplanes, and tend to own them a LONG time. After the JetProp program was established, Rocket Engineering designed a PT- 6A-21 conversion for the Beechcraft Bonanza (B36TC). This Incredible Plane: Cessna 152 Aerobat: Spin Cycle! Darwin Conrad and Jeanie Sadler, who are majority owners of both companies, say the companies work force could more than double in size over the next five years if demand for their airplane conversions … No matter how well the engines were treated and maintained, Dukes rarely got past 1,000 hours before needing significant tops or even major overhauls. THIS ROCKET ENGINEERING CONVERSION GIVES A B36TC A HUGE BOOST By Bill Cox Photography Byo James Lawrence T'S A REALITY NONE OF US LIKE TO THINK ABOUT, BUT AVGAS IS PROBABLY ON rrs WAY OUT. These airplanes are still Jetprops and are fabulous airplanes for the pilot that values efficiency. It took probably five minutes for IAS to peak, but the final number was 197 knots at 1 degree C. That works out to a true of 301 knots at 75 gph total burn. This suggests single-engine service ceiling (SESC) is well above that height. The lost weight came out of a fairly forward CG position, and that shifted the balance point well aft. The conversion includes a … As of September 2008, 233 JetPROP conversions had been completed and delivered by Rocket Engineering … Here’s the point…the -21 becomes “temp limited” (meaning the torque is now decreasing for the rest of the flight) at about 12,000 MSL (in most situations) and the -34/35 becomes “temp limited” at about 15,000 MSL. Basically, the Royal Turbine Duke is the exact same conversion as the popular JetPROP times two. The “dash number” for a PT6 engine relates generally to the size of the engine and the amount of air that can be forced through the compressor section. The original Duke B60 carried 232 gallons of avgas, adequate for the Lycomings, but more than a little short-legged at the Royal Turbine’s 75 gph fuel burn (at max cruise and 23,000 feet). The procedure takes 12 weeks and the average cost is $550,000. We were flying with three aboard plus half fuel, so the airplane wasn’t nearly up to gross, but it wasn’t exactly light, either. Conrad reports the prototype airplane started with an empty weight of 5,012 pounds against a gross weight of 7,000 pounds (with the VGs installed). It performed well and was popular and was a really good conversion. Original TBO was only 1,200 hours, and reaching even that was questionable. Subtract 1,392 pounds of fuel, and the unconverted Duke was left with only 596 pounds of payload, barely enough for three folks plus baggage. At Oshkosh this past year they announced the "TurbineAir" - a tubroprop conversion … To me, the biggest consideration when buying a Jetprop…any Jetprop…is the purchase price, maintenance history, avionics, interior/paint quality, and engine time…not the engine type. Popular Name: JetPROP DLX (Malibu/Mirage Conversions) Thank you for choosing Aerospace-Aviation360.com for Part Number 96119-01 by Rocket Engineering/Jetprop Llc with Model Number DLX. Rocket Engineering Corporation/Spokane, WA USA is a leading holder of after-market STC’d PT6A turbine conversions for the PA46 Malibu/Mirage (“JetPROP”), Duke B60 (“Royal Turbine Duke”) and Bonanza B36TC (“TurbineAir”) aircraft.. Mastenbroek Aeroskill is factory trained and will support your conversions. But, as the climb continues (and it almost always does continue in the Jetprop since the airplane performs so well at high altitude), the -34/35 will outpace the -21. My point…the slightly slower speed of the -21 translates into only a nominal flight time penalty. Enjoy the unparalleled efficiency and speed of this well-priced 2003 JetProp DLX (-35) conversion of the desirable 1999 Mirage airframe. Conrad commented that he had seen nearly 4,500 fpm flying alone on flight tests with 100 gallons aboard. Owner is stepping up to Jet. rocketengineering.com is 2 decades 2 years old. All rights reserved. To my way of thinking, 9 minutes doesn’t move the needle very far on a flight of that length. After Conrad’s turbine conversion, empty weight is now 4,480 pounds. Despite such enthusiasm, the pricey Duke was only a limited success. On the way downhill from our cruise checks, Conrad suggested I stop momentarily at 21,000 feet and shut down the right engine. Also, you’ll typically be flying behind older, unwarranteed engines and may be susceptible to higher maintenance. 6427 Rutter Road Spokane, WA 99212 Phone: (509) 535-4401 Fax: (509) 534-2025 www.jetprop.com The Best Just Got Better! Minimum single-engine control speed on the Royal Turbine has been set at 91 knots, compared to about 81 knots on the original Duke. Keep in mind that was from Truckee’s scenic strip just north of Lake Tahoe, 5,900 feet up in the pine country of the Sierra Nevada. ; and 2) How much hourly operating cost can you afford? As avgas becomes progressively more expensive and less available, more pilots of upscale singles and twins are looking for alternatives. Conrad plans to offer two engine options on the Royal Turbine. So, the more air that can be forced through the compressor the more fuel can be burned and more power is generated. I think it is simply “numerical prejudice”, but the -21 is less popular. Flying in smooth air, I let the Royal Turbine run out to its maximum indicated airspeed. When the airplanes were up and running, they manifested the same delightful handling as the Baron plus significantly better climb and cruise performance. That’s about 160 airplanes, and Conrad and company aren’t done yet. This is an ASAP Semiconductor owned and operated website. They were the first to install the PT6 on the PA46 airframe to create the Jetprop (which is a wildly successful STC with 305 conversions (to date) in the air), and the Royal Duke was a natural conversion … That may be a bit of an over-simplification, but it’s a general good rule of thumb. That’s just not enough of a time consideration to make a huge difference. So, don’t hesitate if you find a good -21 on the market. We are a leading supplier of aircraft engine mounts. Easy browsing, fast Shipping. This is a pristine, Sun Aviation & Rocket Engineering maintained 2015 Jetprop conversion with all available options. In addition to strong climb and 300-knot cruise, another important payoff on the Royal Turbine is a significant improvement in payload.

This Incredible Plane: Scaled Composites Proteus. Conrad’s replacement P&W turboprops put out 550 shp to the same or higher altitude. I’d take a nice, well-maintained -21 any day over a less-than-stellar -34/-35. But, as the climb continues, the ITT increases and the torque decreases. Of course, some pilots prefer two engines, and others, movie stars, executives and captains of industry, are mandated by employment contracts not to fly in any single-engine airplane. Is this appropriate? So, although there are fewer -21 Jetprops on the market, there are certainly fewer buyers for the -21 than for the -35. Now, there’s one more. The cost is US$409,900.
