How much does a GTF engine cost?
The program cost is estimated at $10 billion. The list price was $12 million in 2011. At the start of its production in 2016, each GTF was costing PW $10m to build, more than the sale price, but should become less than $2m per engine.
How much does a Pratt & Whitney jet engine cost?
The total cost to complete the Pratt F135 engine is now estimated to be $7.28 billion — $2.5 billion more than the $4.8 billion initially projected for the engine, according to the document, which was first reported by Aviation Week magazine on its website on Wednesday.
How much is a turbofan?
It’s hard to say how much a turbofan engine costs because it’s included in the overall cost of a plane, but (depending on type and thrust) it’s roughly between 12 and 35 million dollars.
What planes use Pratt and Whitney engines?
P&W engines can be found on the A220, the A320 family, A330, 747-400s, 767, and Embraer E-jets. In recent years, the manufacturer has seen its narrowbody aircraft engines do well and has been focusing on those.
Does Airbus use Pratt and Whitney engines?

What engines do the f35 use?
The Pratt & Whitney F135 two-spool afterburning turbofan engine powers all three variants of the Lockheed Martin F-35 Lightning II – Joint Strike Fighter. The F135 propulsion system is the most powerful fighter engine ever developed.
What airlines use Pratt and Whitney engines?
United is the only U.S. airline with the Pratt & Whitney PW4000 in its fleet, the FAA said. United says it has 24 of the 777s in service. The United 777 aircraft in Saturday’s incident is 26 years old.
What is the advantage of geared turbofan?
In a geared turbofan, a planetary reduction gearbox between the fan and the LP shaft allows the latter to run at a higher rotational speed thus enabling fewer stages to be used in both the LP turbine and the LP compressor, increasing efficiency and reducing weight.
What is geared turbofan?
A geared turbofan engine is a variant of a conventional turbofan engine in which a reduction gearbox is installed between the fan and the low pressure (low speed) turbine. This lower speed means that additional compressor and turbine stages are required to maintain acceptable component efficiencies.
