The Chrysler turbine engine program that produced the Turbine Car began during the late 1930s and created prototypes that completed long-distance trips in the 1950s and early 1960s. The A-831 engines that powered the Ghia-designed Turbine Car could operate on many fuels, required less maintenance, and lasted longer than conventional piston engines.
In 2006, the base MKII kit cost US$182,000, but since builders can purchase additional components already pre-made by Viper Aircraft, customers spent an average of $350,000 on their kits. [6] They would then have to spend approximately another $300,000 [ 6 ] and around 3,000 to 3,500 hours to complete the aircraft. [ 4 ]
Hush kits can adversely affect the range and performance of the aircraft they are fitted to because of the extra weight. It also reduces engine performance and aerodynamic efficiency. For example, the hush kit fitted to the Gulfstream II adds 106 kilograms (234 lb) to the total airplane weight of 65,500 lb (29,700 kg), causing around a 1.6% ...
DePalma later sold Toodles to the Packard Motor Car Company, which used the car's engine as the inspiration for its seven-liter (430 cu in) Twin Six, which became the world's first production 12-cylinder engine in 1916, as well as a 250 hp (190 kW), 14.8-liter (900 cu in) V12 aircraft engine in 1917.
The Bede BD-5 Micro is a series of small, single-seat homebuilt aircraft created in the late 1960s by US aircraft designer Jim Bede and introduced to the market primarily in kit form by the now-defunct Bede Aircraft Corporation in the early 1970s.
The Pearl 700 will power the Gulfstream G700, a stretch of the previous G650, and the G800, with more range than the G650ER. Evolved from the BR725 with a similar architecture plus a fourth low-pressure turbine stage and a 2 in (5.1 cm) larger, 51.8 in (132 cm) blisk fan, its bypass ratio is higher than 6.5:1 and its overall pressure ratio ...
Sonex The original model, incorporating a low-wing design, seats two, and a conventional tail. Available as plans or a kit. [4] [12]Sonex B Introduced in April 2016, this model is a modification of the original Sonex, with an enlarged cockpit for larger and taller pilots, a center "Y-stick", electric flaps and dual throttles as standard.
For commercial jet aircraft the jet noise has reduced from the turbojet through bypass engines to turbofans as a result of a progressive reduction in propelling jet velocities. For example, the JT8D, a bypass engine, has a jet velocity of 400 m/s (1,450 ft/s) whereas the JT9D, a turbofan, has jet velocities of 300 m/s (885 ft/s) (cold) and 400 ...
