JetZero has been selected by the U.S. Federal Aviation Administration (FAA) to receive $5.3 million under Phase IV of the FAA's Continuous Lower Energy, Emissions and Noise (CLEEN) programme. The award will fund engine and nacelle instrumentation that will collect data for top-mounted engines in an all-wing configuration.

Under the CLEEN IV award, JetZero will capture and share airflow data at the engine inlet and fan exit across takeoff, climb, cruise, and crosswind ground operations in a representative operational environment rather than on costly engine rigs or simulated ground-plane tests.

JetZero's design has the engines mounted on top of the fuselage, reducing noise for airport communities. The Z4 is designed to deliver up to 50% better fuel efficiency than comparable-class tube & wing aircraft using the same propulsion technology, with entry into service targeted in the early 2030s. The FAA's CLEEN programme is the agency's principal public-private partnership for maturing aircraft technologies that reduce fuel burn, emissions, and community noise, and accelerate their introduction into the commercial fleet.
