It also converts Beech B36TC Bonanzas into the Turbine Air via installation of a 500 HP PT6A-21. AIRCRAFT SALES. By the 1980s mod shops were bolting on turboprops in place of reciprocating engines and achieving impressive speeds, despite the challenges of assuring the airframe could handle the horsepower and juggling the fuel/payload equation on the small airframes. That’s about double the fuel burn of the Aerostar. The hourly cost of a turboprop single is $400-$500 less than a very light jet and requires about half the runway length at the tradeoff of only about 300 knots cruise. It keeps the 3.35 PSI max differential pressurization of the P210 and its max operating altitude of FL230. At the FL270 max operating altitude, the cabin is at 9500 feet. Gross weight is 7050 pounds, max landing weight is 6775 pounds and the published empty weight is 4650 pounds. Write CSS OR LESS and hit save. “ The Cheyenne burns 50 percent more fuel per hour, but my block speed is around 10 percent faster and I buy the fuel for 25 to 35 percent less than avgas,” said Steve. Gross takeoff weight for the Mark I is 3600 pounds and advertised empty weight is 1908 pounds, giving a useful load of 1692 pounds. Gross weight is 4000 pounds; our test flight in 2010 showed an empty weight of 2699 pounds. Conversion with the -35 engines will cost approximately $887,000. Are there any major disadvantages over the equivalent piston engined / turboprop (putting aside the initial cost obviously). Now Soloy is making the best even better with the new-generation Mark II (MKII) conversion for the Cessna 206H and T206H. The modifications fall under separate names; we won’t try to sort out what company owns what other companies, suffice to say that if you go to www.rocketengineering.com, you’ll find further information on all the mods.

Whether you ascribe that phrase to Robert Heinlein's 1966 … Decrease landing distance by 50%. New Fuel Filter 15. With a total of 1,240 shaft horsepower on a 9,000-pound airframe, the takeoff and climb performance advantage over the Aerostar is significant. While the conversion is similar to a pressurized airframe, total usable fuel is less, 106 gallons and empty weights are lower because the airframe is not pressurized. Douglas DC-3. Cheyenne's old-school pressurization controls. Climb rate does peter out in the upper teens, however. With beta and reverse thrust, the Cheyenne also uses far less runway on landing. For more than five decades, active and dedicated aircraft owners and pilots have turned to AVIATION CONSUMER to answer their most important buying questions. Turbine Cougar BaronFinally, Rocket Engineering is flying a prototype pressurized Baron conversion it refers to as the Turbine Cougar Baron. We sell a variety of Blackhawk-powered aircraft featuring low … We’ve also observed that a Soloy 206 on takeoff is far quieter than a piston-powered 206, something important as population pressure continues to affect airports and lakes. Plus we consider the sheer ability to get up and out because of the extra horsepower to be a significant safety factor. Maintenance, including airframe, engine and APU, is estimated to cost … The current crop of turboprops have impressive performance and with additional tankage, short range isn’t the problem it used to be. Our experience is that such data can be a trifle optimistic, especially when it comes to cruise speeds and useful loads. Price to convert an existing P210N is $839,500 and includes an astonishing amount of work on the aircraft beyond the engine installation, such as a Garmin 600 package for the flight deck; new wiring throughout the aircraft; new, heavier horizontal and vertical stabilizer mounts; dual elevator trim tabs; air conditioning and new interior. And if you don’t want to thumb your nose at recommended overhaul intervals, there are maintenance plans that theoretically extend the life of many turbine engines by thousands of hours, often to the point that overhaul may not necessarily be a future responsibility for the average owner who only flies up to a few hundred hours per year. It has proven over decades of operation to be the most reliable and affordable (cost vs. capability) special mission platform on the market. On the ground at idle, the Cheyenne burns 30 gph. ☕ 1 min read. The Cheyenne II, weighing about 8,000 pounds, turned in a speed of 242 KTAS on 66 gph with a density altitude of 27,100 feet. There were only two practical … The zero-fuel weight is also 4100 pounds. Props are full-feathering and reversing and feature a choice of either a three-blade Hartzell or five-blade MT; we are quite interested in the noise footprint of the latter installation, as we suspect it’s low. Published TBO is 3600 hours with the hot section requirement dropped if trend monitoring is used. Any shop with PT6 experience should be able to take care of one. At $499,000, the airplane has a published cruise speed of 250 knots at FL250 while burning 29 GPH, according to Rocket Engineering. Steve said he nearly always climbs at 140 KIAS to turn in climb rates of 2,500 to 3,000 feet per minute. Operationally, pistons are more temperamental, especially those that are force-fed with turbochargers. History shows the Douglas DC-3 to be one of the greatest airplanes of all time. Lisa and Steve Lefferts’s turbine experience has been good so far. Looking at the DL, the economy version of the JetPROP, climbing to FL250 and operating at max cruise power generates a published true airspeed of 231 knots on a fuel burn of 28.4 GPH. But used twin turboprops from the 1970s and ’80s have drastically come down in purchase price, making the cost of entry close to that of high-end piston twins. This website contains many older reviews. American Aviation Inc.'s Pitot Cowls provide better intake airflow than the original intakes. For those who fly regularly where the avgas supply is iffy or who want a big performance bump and turbine reliability in an airframe that is as familiar as an old boot, these mods are worth serious consideration.
