JetZero selects Boeing 757 engine for Z4 demonstrator

JetZero has chosen the Pratt & Whitney PW2040 engine to power its Z4 demonstrator plane. This aircraft is a blended-wing-body design, with plans for its first flight in 2027 and commercial use by 2030. Although the PW2040 engine is a legacy engine from the Boeing 757, it is still unclear what engine will be used for final production. JetZero aims to revolutionize commercial aviation with its Z4 aircraft. The company claims it will reduce fuel consumption and carbon emissions by up to 50% compared to current models. It plans to carry around 250 passengers over a distance of approximately 4,000 nautical miles. Several notable investors, including the United States Air Force and major airlines like Delta and Alaska Airlines, are backing JetZero. Contractors such as Northrop Grumman and Collins Aerospace are collaborating with JetZero to bring the aircraft to life. One innovative feature of the Z4 design is its engine placement. Unlike traditional planes where engines are mounted under the wings, the Z4 will have its engines mounted on top. This change is expected to make the aircraft quieter. While the PW2040 engine is outdated, it provides a readily available option for the demonstrator phase. JetZero hopes to improve aircraft efficiency and has plans to eventually use more advanced engines or even hydrogen-powered options in the future. Today’s commercial jets operate under conventional designs, but JetZero believes the blended-wing-body design is the future of aviation. The company is moving quickly, aiming for its aircraft to be in service in just five years. However, whether this timeline is realistic remains to be seen.
