The convergent-divergent nozzle is fully variable for both the convergent throat and divergent areas for high nozzle pressure ratio and can vector ±20° in the pitch axis, greatly improving the aircraft's pitch authority by augmenting the pitching moment of the tail with engine thrust; this enables the F-22 to remain controllable while flying at a trimmed alpha of over 60°. The thrust vectoring is fully integrated into the F-22's flight control system to facilitate handling. The rectangular nozzle consists two wedge-shaped flaps for stealth and also contribute to lower
322:; features that facilitate engine maintenance and servicing include modular design such as an axially split case, color-coded cables and harnesses, and a reduction of the number of hand tools required for servicing to just five. Most components are one-deep and servicing can be conducted while wearing hazmat protective clothing. The engine has a design life of 8,650 total accumulated cycles, with inspection and overhaul of the hot section approximately every 2,000 hours and the cold section every 4,000 hours.
226:& Whitney's design changed to incorporate a 15% larger fan, increasing bypass ratio from 0.25 to 0.30. However, unlike General Electric, Pratt & Whitney did not fit its larger fan on flightworthy YF119s for the ATF flight demonstrators to avoid potential reliability issues that may arise. Instead, the revised fan was extensively ground tested at Wright-Patterson Air Force Base. As a result, both the YF-22 and YF-23 had lower performance with the YF119s than with the YF120s.

Detailed design of Pratt & Whitney's submission, designated internally as PW5000, began when the request for proposals (RFP) for JAFE, later renamed the ATF Engine (ATFE) program, was released in May 1983. Advances in engine technology, such as those from the Advanced Turbine Engine Gas Generator (ATEGG) and the Joint Technology Demonstration Engine (JTDE) programs, allowed the design to do more

354:. In contrast, YF119-PW-611 on the X-35 had a round axisymmetric nozzle that can swivel downwards while the low-pressure spool drives a lift fan that's engaged through a clutch; engine bypass air is also routed to roll posts for additional lift and stability. The X-35 won the JSF competition and its shaft-driven lift fan system, called

The YF119 on the YF-23 had a single-expansion ramp nozzle (SERN) consisting of a variable wedge flap on the top and a fixed ramp on the bottom, which then transitions to a trench on top of the aft fuselage. While the SERN lacked thrust vectoring capability, it allowed the exhaust to be further cooled

The F119 is a twin-spool axial-flow low-bypass turbofan. It has a three-stage fan driven by a single-stage low pressure turbine and six-stage high pressure compressor driven by single-stage high pressure turbine. The shroud-less fan has wide-chord, low aspect ratio hollow titanium fan blades that are

On 3 August 1991, Pratt & Whitney was awarded the EMD contract for ATF engine, while the
Lockheed/Boeing/General Dynamics team won the contract for the ATF airframe. While the YF119 was a more conventional design compared to the General Electric's variable cycle YF120, Pratt & Whitney accrued

ATF technology and flight demonstrators. The ATF's increasing weight during development required more thrust to meet the performance requirements; as gross weight grew to 60,000 lb (27,200 kg), the required maximum thrust was increased by 20% to 35,000 lbf (156 kN) class. Pratt

and impingement cooled using air from the high-pressure compressor. The high and low pressure spools are counter-rotating. The requirement for the ATF to supercruise, or fly supersonic without afterburners, results in a very low bypass ratio of 0.30 for the F119-PW-100 in order to achieve high

thrust in intermediate, or non-afterburning power. The combustor, internally named
Floatwall, eliminated welds to mitigate crack growth due to thermal cycling. The original RFP called for maximum thrust in the 30,000 lbf (133 kN) class for an aircraft gross weight of 50,000 lb

The specialized YF119 variants on the X-32 and X-35 had provisions for short takeoff and vertical landing (STOVL) operations. The YF119-PW-614 on the X-32 had a pitch-axis thrust vectoring nozzle and valves can redirect the engine exhaust and bleed air to provide direct lift, similar to the
