The Lockheed/ Boeing/ General Dynamics YF-22 is an American single-seat, twin-engine, stealth fighter technology demonstrator prototype designed for the United States Air Force (USAF). The design team, with Lockheed as the prime contractor, was a finalist in the USAF's Advanced Tactical Fighter (ATF) competition, and two prototypes were built ...
YF119-PW-100L: Prototype engine for the YF-22; rated 30,000 lbf thrust class. YF119-PW-100N: Prototype engine for the YF-23; rated 30,000 lbf thrust class. F119-PW-100: Production engine for the F-22A with larger fan and increased bypass ratio (BPR) rated for 35,000 lbf thrust class. YF119-PW-611: Prototype engine for the X-35.
The YF120 had different nozzle designs for the YF-22 and YF-23 technology demonstrator prototypes tailored to the specific airframe. The YF120 on the YF-22, registration number N22YF, was equipped with thrust vectoring nozzles. The engine for the YF-22 featured a two-dimensional thrust vectoring nozzle that could vector in the pitch direction ...
The aircraft had single-expansion ramp nozzles (SERN) and, unlike the YF-22, did not employ thrust vectoring. [29] As on the B-2, the exhaust from the YF-23's engines flowed through troughs in the aft deck lined with heat-abating tiles to shield the engines from infrared homing (IR) missile detection from below.
General Electric developed a variable cycle engine, known as the GE37 or General Electric YF120, for the YF-22/YF-23 fighter aircraft competition, in the late 1980s. GE used a double bypass/hybrid fan arrangement, but never disclosed how they exploited the concept.
In order to fly the F-22, Larson said he had to go through basic pilot training, consisting of 55 weeks of flying in trainer aircraft like the T-6 Texan II and a T-38 Talon.
The Advanced Tactical Fighter (ATF) was a program undertaken by the United States Air Force to develop a next-generation air superiority fighter to replace the F-15 Eagle in order to counter emerging worldwide threats in the 1980s, including Soviet Sukhoi Su-27 and Mikoyan MiG-29 fighters under development, Beriev A-50 airborne warning and control systems (AWACS), and increasingly ...
The military-wide grounding of V-22 aircraft in December came a week after eight airmen were killed when their CV-22 crashed off the coast of Yakushima Island, Japan — as well as a number of ...
