Vertical Aerospace has officially commenced testing on a new hybrid-electric propulsion system designed for its Valo electric vertical take-off and landing (eVTOL) aircraft. Trials are currently underway at the company’s Hybrid Propulsion Evaluation Rig facility in England. By integrating a sustainable aviation fuel-compatible gas turbine with an electric generator, the aircraft is expected to achieve an operational range of up to 1,000 miles—a tenfold increase over the all-electric version. Capable of transporting 2,425 lbs of cargo, the platform is being developed for diverse applications, including defense operations, emergency response, and logistics, with autonomous flight capabilities.
The testing phase at the Cotswold Airport facility focuses on the full integration of the hybrid powertrain. Engineers are evaluating the turbine, generator, and electrical systems to ensure the control architecture and fault-response mechanisms function correctly under demanding conditions. This rigorous validation process is a critical precursor to upcoming ground and flight demonstrations. The hybrid model’s design offers significant tactical advantages, such as reduced heat and noise signatures, which make it particularly suitable for military environments where stealth and efficiency are paramount.
Beyond the propulsion system, the company is advancing its manufacturing capabilities at the Vertical Energy Center. Vertical Aerospace recently unveiled its first all-electric Valo battery produced on an upgraded, automated assembly line. These battery packs are undergoing extensive environmental and operational testing to meet the stringent requirements of the UK Civil Aviation Authority and the European Union Aviation Safety Agency. As the company works toward certification, it is simultaneously preparing for commercial production to fulfill approximately 1,500 pre-orders from global aviation partners, including American Airlines, Japan Airlines, and the Bristow Group.
