rocket engineering jetprop conversion

“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. 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. Like all sophisticated, medium twins, Dukes suffered other ills associated with pressurization, hydraulics and electrics as they aged, but the engines were, by far, the major problem. Level and trimmed with the right mill feathered, right wing five degrees up, ball half out of center and the left thrust lever against the stop, airspeed finally stabilized at 240 knots true. 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. Flying in smooth air, I let the Royal Turbine run out to its maximum indicated airspeed. When it does, I get a lot of questions from prospective buyers, most wanting to know if the -21 is “worth owning”. 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. 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). So…the -34/35 should beat the -21 to FL270 by a 2-3 minutes, easy. 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. The standard, turbocharged Duke engines provided 380 hp per side to a critical altitude of about 17,000 feet. The procedure takes 12 weeks and the average cost is $550,000. 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. 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. As of September 2008, 233 JetPROP conversions had been completed and delivered by Rocket Engineering of Spokane, WA. - Photo taken at Samedan (St. Moritz) - Oberengadin (SMV / LSZS) in Switzerland on August 31, 2003. The Top 10 Planes Of All Time: WARNING: This List Goes To 11. 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 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. These airplanes are still Jetprops and are fabulous airplanes for the pilot that values efficiency. Enjoy turbine performance with piston economics. Is this appropriate? The airplane’s cruise climb at 175 knots was even more interesting at 2,000 fpm. 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 fuel/air ratio that is burned in a PT6 engine is the same at any altitude. 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: … Owner is stepping up to Jet. It won't happen next year or the year after, perhaps noteven for another 20 years, Nevertheless, Duke owners almost unanimously adored their airplanes. 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. 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. But, at high altitude (with the less dense air), the smaller -21’s power drops off quickly. So, today you can only purchase a -21 Conversion or a -35 Conversion from the factory in Spokane. Plane and Pilot expands upon the vast base of knowledge and experience from aviation’s most reputable influencers to inspire, educate, entertain and inform. 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 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 Concerning comparative costs, there are two variables to consider: initial acquisition costs and engine reserve costs. It has attracted customers here in the United States and especially in countries where avgas is prohibitively expensive or simply not available. It has attracted customers here in the United States and especially in countries where avgas is prohibitively expensive or simply not available. To date, Rocket has converted 10 Bonanzas to turbine power in a little over one year of production. 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 … Photo of The Week: Our Christmas List: A $72,000 Mach .84 Jet. Equipped with SynVis G500, user-friendly dual Avidyne IFD's, KMD850, upgraded … Get 96119-01 by Rocket Engineering/Jetprop Llc for aircraft model DLX. As no active threats were reported recently by users, rocketengineering.com is SAFE to browse. Buyers of a Jetprop value speed and many simply don’t understand buying anything that is “slower”. This is a pristine, Sun Aviation & Rocket Engineering maintained 2015 Jetprop conversion with all available options. 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. All rights reserved. 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. … Minimum single-engine control speed on the Royal Turbine has been set at 91 knots, compared to about 81 knots on the original Duke. 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. 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. 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. 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. Piper Aircraft themselves saw the … And, remember…”power is always popular”. 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. Effectively, the -21 performs nearly identically to the -34/35 at low altitude. 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. 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. rocketengineering.com is 2 decades 2 years old. Normal multi-engine service ceiling, incidentally, remains the Duke’s original 30,000 feet. In addition to strong climb and 300-knot cruise, another important payoff on the Royal Turbine is a significant improvement in payload. 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. JETPROP- LLC: JETPROP DLX Among one of the stronger programs on the market- the JetPROP DLX is well along in its second decade of service- with more than 240 of this conversion delivered as of September 2009. 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. In order to rebalance the envelope, Conrad relocated both batteries to the nose, as far forward as possible. 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). INFORMATION PROVIDED FOR INTRODUCTION ONLY. But, as the climb continues, the ITT increases and the torque decreases. 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. We launched for the flight levels out of Truckee-Tahoe Airport, in California, on one of those crystal-line, Chamber of Commerce days. 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. A turbine engine is normally “torque limited” at lower altitudes and “temp limited” at higher altitudes. © 2020 Madavor Media, LLC. That’s about 160 airplanes, and Conrad and company aren’t done yet. The base airframe converted provides the main foundation for the success of the JetPROP DLX: a strong single … 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. 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. The P&W turbines were collectively about 550 pounds lighter than the Lycomings, but that didn’t all translate to additional payload. 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 … As a result, Conrad increased fuel capacity to 267 gallons of heavier jet fuel, reducing the theoretical payload improvement to 153 pounds—still impressive. ASAP 360 Unlimited provides aircraft engine mounts with large no of inventory. So, it seems appropriate for me to leap into the gap and post my thoughts on the -21. Twenty percent of the entire PA-46 fleet have been converted. So, Rocket Engineering did what they do best…take a great airframe and mount a great engine (PT6) on the front. The cost is US$409,900. Basically, the Royal Turbine Duke is the exact same conversion as the popular JetPROP times two. Rocket Engineering's new TurbineAir ... After that came the groundbreaking conversion for the Malibu. Are there any major disadvantages over the equivalent piston engined / turboprop (putting aside the initial cost obviously). Most Jetprop buyers are previous owners of piston PA-46’s and love their piston steed, but they always dream of the day they can afford a turbine, and want the “most power they can buy”. Rocket Engineering was an early pioneer and saw the potential of converting the piston-powered Malibu into their turboprop version – the JetPROP. On the way downhill from our cruise checks, Conrad suggested I stop momentarily at 21,000 feet and shut down the right engine. 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. The increase in power from 380 hp to 550 shp per side caused an increase in Vmc. 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. Conversion takes about 14 weeks and is completed by Rocket Engineering at Felts Field, Spokane, Washington state. The Royal Turbine is the latest product of the fertile imaginations of Darwin Conrad and Jeanie Sadler of Rocket Engineering in Spokane, Wash. Conrad has been through the STC certification wars many times, and he’s as familiar as anyone can be with the FAA’s requirements. There’s is one disadvantage to the -21…the market does not favor the -21. The Jetprop DLX produced by Piper. Right up front, the most obvious difference is sheer, brute power. As of September 2008, 233 JetPROP conversions had been completed and delivered by Rocket Engineering … What is “numerical prejudice”? 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. PRICE JUST REDUCED! Become a member and get exclusive access to articles, contests and more! 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 … 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. 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). Fresh Annual in October! ... they are making all those sweet jetprop conversion). Predictably, converting a piston airplane to turbine power wasn’t exactly a slam dunk. 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. JetPROP and Rocket Engineering, based in Spokane, Washington, have performed 148 conversions (32 of which are from Europe) since receiving certification in 1998. In 2002, Conrad and Sadler launched into a development program to replace everything from the firewall forward on the prototype Duke. No damage history, no excuse, ready to fly airplane. Conrad plans to offer two engine options on the Royal Turbine. This is an ASAP Semiconductor owned and operated website. ; and 2) How much hourly operating cost can you afford? Jetprop conversions - any disadvantages? 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. After Conrad’s turbine conversion, empty weight is now 4,480 pounds. The engines were so unreliable that many Dukes spent much of their time on the ramp or in the shop. It performed well and was popular and was a really good conversion. At Oshkosh this past year they announced the "TurbineAir" - a tubroprop conversion … New parts added daily. The -34/35 will cruise at 260KTAS (average) at FL270, and the -21 will cruise at about 243 KTAS (average) at the same altitude. Easy browsing, fast Shipping. That may be a bit of an over-simplification, but it’s a general good rule of thumb. It’s a magic number and one not often seen in turboprop corporate aircraft.

Conrad reasoned that things could only get better and more reliable (if more expensive) by replacing the troublesome TIO-541s with P&W turboprops. 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. 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. A lower cost JetPROP DL conversion became available in October 2003 utilizing the P&W PT6A-21. Together, Rocket Engineering and JetPROP now employ nearly 50 people at the Felts Field building they share, and that number is increasing by about one employee per month. Not in my book. 6427 Rutter Road Spokane, WA 99212 Phone: (509) 535-4401 Fax: (509) 534-2025 www.jetprop.com The Best Just Got Better! It won't happen next year or the year after, perhaps noteven for another 20 years, but it'S likely avgas … As avgas becomes progressively more expensive and less available, more pilots of upscale singles and twins are looking for alternatives. Rocket Engineering's flagship PT6A-35 conversion on the best pressurized, cabin-class, single engine airframe! This suggests single-engine service ceiling (SESC) is well above that height. 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. But, it sometimes takes a low price or a knowledgable buyer to jump into the -21 market, especially if other -34/35 offerings are available. My point…the slightly slower speed of the -21 translates into only a nominal flight time penalty. 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. Despite such enthusiasm, the pricey Duke was only a limited success. If that seems a bargain, it is—except for one major problem. Conrad’s replacement P&W turboprops put out 550 shp to the same or higher altitude. So, it seems appropriate for me to leap into the gap and post my thoughts on the -21. To date, Rocket has converted 10 Bonanzas to turbine power in a little over one year of production. 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. Effectively, the -34 and -35 Conversions provide the same performance, so I will contrast the -34/35 collectively with the -21 in this discussion. 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).
