Vertical Aerospace reports it has successfully completed the second stage of piloted thrustborne testing of its full scale VX4 prototype. The company is now preparing for a new chapter in its history, with the VX4 entering the penultimate phase of flight testing: wingborne flight.
“This phase will mark a defining moment in the VX4’s development, pushing beyond the limits of the secure airspace of Cotswold Airport’s airfield and into real-world operating conditions for the first time,” said the company in a press release. “During Phase 2, the aircraft completed over thirty piloted test flights. Flight tests included completing successful hover and low speed flight manoeuvres, as well as executing handling and performance procedures including roll, yaw, and spot-turns. Engineers were able to collect hundreds of data points to determine the reliability of the aircraft systems, as well as thrust levels, lift efficiency, and power-to-thrust ratio and control responsiveness.
“These piloted prototype flights experienced no system failures and exceeded expectations for stability and performance.”
Simon Davies, Vertical’s Chief Test Pilot, who flew the VX4, said: “This phase of testing allowed us to put the VX4 through key flight manoeuvres in real-world conditions, giving us valuable insights into its reliability and responsiveness under more demanding scenarios. The aircraft performed exceptionally, being just as stable and simple to fly as our simulations.”
To progress to wingborne flight, the next phase of the flight test programme, the UK Civil Aviation Authority (CAA) will first need to expand Vertical’s Permit to Fly. Once approved, the VX4 will take off, fly, and land like a conventional aircraft, with lift generated by its wings rather than its rotors.
“Transitioning from a tightly controlled test environment to more dynamic, scalable operations is a major leap forward on the path to full certification and commercial viability,” said the company. “Once the aircraft has completed wingborne flight, the aircraft will have, in effect, completed a mini-certification process with this prototype. While Vertical works with the CAA to expand its Permit to Fly it will continue to perform important system and component testing as well as progressing the development of an identical full-scale prototype which will accelerate the VX4’s flight test programme and demonstration capability. Following wingborne testing, the VX4 will enter a final phase of transition testing to demonstrate its ability to switch between vertical and forward flight modes.”
