How much does an F135 engine cost?
Unit prices vary, as the conventional take-off and landing F-35A’s engine is priced lower than the propulsion system for the vertical take-off and landing variant F-35B. P&W was awarded $1.95 billion to supply 99 F135s during the Lot 10 production phase, at an average cost per engine of around $19.7 million.
How does the F135 engine work?
The F-35 engine utilizes a six-stage high pressure compressor. A compressor is essentially a disc with perpendicular square faces that protrude outwards and spins on a shaft. A six-stage compressor means there are six of these discs placed in series, one right after the other.

What aircraft uses the F135 engine?
The F135 propulsion system is the most powerful fighter engine ever developed. The F135-PW-100 powers the U.S. Air Force F-35A Conventional Take-Off and Landing (CTOL) variant and provides 28,000 pounds of thrust or as much as 43,000 pounds with afterburner.
What is the most powerful jet engine?
GE9X engine
The GE9X engine for the Boeing 777X has been recognized by the Guinness Book of World Records as the the most powerful commercial aircraft jet engine (test performance) after reaching 134,300 lbs of thrust.
What is the most powerful military jet engine?
F135
defined by capability Not only is the F135 the most powerful and most advanced fighter engine ever produced, it’s also the most dependable – demonstrating a step change in readiness and reliability over 4th generation fighter engines.
How does F-35 lift fan work?
The lift fan, located towards the front of the aircraft, acts as a counterbalance by using two counter-rotating blisks. Unheated engine bypass air is then diverted through nozzles mounted on the wings of the aircraft, called roll posts, in order to allow roll control.
What is the most powerful jet engine ever built?
Who makes the F-35 lift fan?
Rolls-Royce LiftSystem
The Rolls-Royce LiftSystem, together with the F135 engine, is an aircraft propulsion system designed for use in the STOVL variant of the F-35 Lightning II. The complete system, known as the Integrated Lift Fan Propulsion System (ILFPS), was awarded the Collier Trophy in 2001.
How long do airplane engines last?
Older and smaller jet engines typically have TBOs of 5,000 hours at the most. More modern engines have about 6,000 hours or more. With most business jets accumulating less than 500 hours of flying time a year, the schedule for modern jet engine MRO operations averages about 12 years or more.
How many SHP does a F135 engine have?
The driveshaft connects the F135 engine to the lift fan and delivers as much as 29,000 shp. The lift fan provides the forward vertical lift. It is a 50-inch, two-stage counter-rotating fan, which is able to deliver more than 20,000 pounds of thrust.
Who are the manufacturers of the Boeing F135?
The F135 team is made up of Pratt & Whitney, Rolls-Royce and Hamilton Sundstrand. Pratt & Whitney is the prime contractor for the main engine, and systems integration.
What are the different variants of the Ford F-135?
There are 3 F135 variants: the -100 engine, -400 engine, and the -600 engine. The -400 is similar to the -100, the major difference being the use of salt-corrosion resistant materials.
Why did Pratt&Whitney stop making the F135?
Pratt & Whitney managed to meet their 2015 production goals, but “recurring manufacturing quality issues” in turbine blades and electronic control systems required engines to be pulled from the fleet. Derived from the F119 engine, the F135 is a mixed-flow afterburning turbofan with a new fan and LP turbine.
