Leading develop of zero-emission solutions for commercial aviation ZeroAvia has received its second twin-engine 19-seat Dornier 228 aircraft at its headquarters in Hollister, California. The new U.S. initiative will take the system developed in the UK HyFlyer II project and integrate it into the same type of aircraft. It will serve as the basis for testing new components and integrations, as well as a testbed for working with the FAA ahead of the ZA600 engine's planned certification in 2024. The company will test new components and integrations under an FAA certificate ahead of the ZA600 engine's planned certification in 2024.ZeroAvia will work towards a hybrid engine configuration that incorporates both the company's hydrogen-electric powertrain and a conventional engine into the aircraft. The conversion is expected to take approximately 3-4 months to prepare the aircraft for test flights. After the engine is configured, it will enter into the flight testing and demonstration program, spanning passenger, cargo, and industrial use cases with a number of to-be-announced partners.In addition to the launch of this program, ZeroAvia will be expanding its facility at Hollister to ensure adequate staff and resources to reach planned milestones. The company has added a new 15,000 square foot hangar to its footprint at the airfield, enabling space for conducting engineering work on the aircraft and its HyperTruck test bed platform, as well as ample office space to support its growing operations.Last fall, ZeroAvia conducted the first program ground test of its HyFlyer II program and successfully tested the flight-intent 600kW powertrain with its 15-ton HyperTruck mobile ground testing platform. The HyperTruck, developed based on heavy-duty military trucks, is sized to also support testing the company’s larger planned powertrain (ZA-2000, with shaft power over 1.8 megawatt) which can be used to test systems for 40-80 seat aircraft.
