RTX has confirmed its Pratt & Whitney unit will supply the PW2040 engines for JetZero’s demonstrator aircraft. Collins Aerospace will provide nacelles for the project. This comes after JetZero dropped plans to use P&W’s geared turbofan powerplants.
The engine maker’s PW2000 family powers Boeing 757s, and a military derivative is used on the C-17 strategic transport. RTX Canada will also supply an APS3200 auxiliary power unit for the blended-wing-body aircraft. Collins Aerospace will design and build nacelle structures, including fairings and support structures.
JetZero aims to develop a conceptual demonstrator called the Z4, which will have twin turbofans on its aft fuselage. The company plans to conduct its first flight in 2027. This project envisions an aircraft that could burn half as much fuel as current planes, with estimates suggesting it could travel 5,000nm and carry 200-250 passengers.
The blended-wing-body design allows the entire structure to create lift, rather than just the wings. JetZero’s development is influenced by both traditional tube-and-wing designs and flying wing concepts. RTX’s involvement comes after Delta Air Lines agreed to assist with operational and cabin-design input.
