JetZero Receives $5 Million For Blended Wing Body Research

The FAA has awarded JetZero $5.3 million to study airflow through its top-mounted engines on the Jet1 demonstrator, a full-scale prototype of the company’s blended-wing-body Z4 airliner. The funding comes from the agency’s Continuous Lower Energy, Emissions, and Noise program. JetZero aims to use the data to improve fuel efficiency and reduce noise for communities near airports. The company plans to put the Z4 into service in the early 2030s, with United Airlines and Delta Air Lines already showing interest. This development was first reported by AIN Science & Technology Editor Hanneke Weitering in Leeham News.
