The Ayres Thrush, formerly the Snow S-2, [1] Aero Commander Ag Commander, and Rockwell Thrush Commander, is an American agricultural aircraft produced by Ayres Corporation and more recently by Thrush Aircraft. It is one of the most successful and long-lived agricultural application aircraft types in the world, with almost 2,000 sold since the ...
The PBS TJ100 is a Czech turbojet engine produced by PBS Velká Bíteš.The TJ100 engine entered service in 2003, [1] and is the most popular of PBS's turbojet engines as more than 1,000 engines have been sold to 40 countries worldwide. [2]
Mockup with compressor and turbine cutaway. After the budget of NASA on aeronautics research was severely cut at the start of 2006, Pratt & Whitney committed to spend $100 million a year on the geared turbofan (GTF) development for the next generation of single-aisle airliners, focused on the 25,000–35,000 lbf (110–160 kN) thrust range.

NASA was loaned 2 SR-71 aircraft for research work. One was modified to flight-test a Linear Aerospike rocket engine and was fitted with thrust-enhanced J58 engines. [5] Engine thrust was increased by 5% to offset increased aircraft drag. The increased thrust came from a throttle push, or exhaust gas temperature uptrim, of 75 °F (42 °C).
The Pratt & Whitney PW4000 is a family of dual-spool, axial-flow, high-bypass turbofan aircraft engines produced by Pratt & Whitney as the successor to the JT9D.It was first run in April 1984, was FAA certified in July 1986, and was introduced in June 1987.
Reverse thrust can be generated to aid braking after landing by reversing the pitch of variable-pitch propeller blades, or using a thrust reverser on a jet engine. Rotary wing aircraft use rotors and thrust vectoring V/STOL aircraft use propellers or engine thrust to support the weight of the aircraft and to provide forward propulsion.
The Westinghouse J34, company designation Westinghouse 24C, was a turbojet engine developed by Westinghouse Aviation Gas Turbine Division in the late 1940s. Essentially an enlarged version of the earlier Westinghouse J30, the J34 produced 3,000 pounds of thrust, twice as much as the J30.
The Pratt & Whitney JT3D is an early turbofan aircraft engine derived from the Pratt & Whitney JT3C.It was first run in 1958 and was first flown in 1959 under a B-45 Tornado test aircraft.
