Vertical Aerospace [NYSE: EVTL] has successfully conducted the first tethered piloted flight of its latest VX4 eVTOL prototype.
The “wheels up” phase of testing commenced with the VX4 prototype performing a piloted flight while loosely tethered to the ground.
During this crucial test, Vertical Aerospace’s team measured over 20,000 flight and system parameters. This comprehensive data collection allowed the company to verify the aircraft’s thrust, handling qualities, and overall system performance.
Stuart Simpson, CEO of Vertical Aerospace, gave comment on the latest test flight. “The first tethered flight of our new VX4 prototype represents 14 months of relentless hard work and dedication.”
“We’ve taken this advanced aircraft from initial design through development and now into the air.”
“This milestone is a testament to the skill and commitment of our talented team, solidifying the VX4’s position as the best eVTOL aircraft available in the market.”
CAA Approval Process
The flight test was made possible after Vertical Aerospace secured a Permit to Fly from the UK Civil Aviation Authority (CAA).
This permit was granted following a rigorous evaluation process, which essentially amounted to a “mini certification” program for the aircraft. The CAA’s assessment covered engineering aspects, design elements, test data, and the aircraft itself.
To progress through each phase of flight testing, Vertical must submit extensive documentation to the CAA. This paperwork is fairly comprehensive, detailing every aspect of the aircraft and its operations, including:
- Safety protocols
- Engineering specifications
- Operational procedures
This meticulous approach ensures that every step in the VX4’s development meets the highest standards of safety and performance.
Next: Expanding the Flight Envelope
Following the success of the initial tethered flights, Vertical Aerospace is set to enter the next phase of testing, pending CAA approval. The upcoming stages include:
- Thrustborne flight testing: This phase will see the VX4 perform vertical take-offs and landings, as well as low-speed flight maneuvers. During these tests, lift will be generated primarily by the aircraft’s propellers.
- Wingborne or conventional flight (CTOL): As testing progresses, the VX4 will demonstrate its capabilities in traditional aircraft flight modes.
- Piloted transition flight: The final and most critical test stage will showcase the VX4’s ability to transition seamlessly between vertical and conventional flight modes.
Each of these phases will only commence after receiving rigorous approval from the CAA, ensuring the utmost safety and compliance throughout the testing process.
The VX4: A Game-Changer in Urban Air Mobility
The VX4’s impressive performance is powered by technology developed at Vertical’s state-of-the-art Energy Centre.
The aircraft features an advanced powertrain with proprietary battery packs capable of delivering a remarkable 1.4 MW of peak power.
This innovative energy system underwent extensive ground testing, including powered propulsion trials, before the tethered flight.
Vertical Aerospace’s VX4 is a four-passenger, piloted Electric Vertical Take-Off and Landing (eVTOL) aircraft designed to revolutionize urban air mobility. Key features include:
- Zero operating emissions, aligning with global sustainability goals
- Partnerships with leading aerospace companies like GKN, Honeywell, and Leonardo
- Proprietary battery and propeller technology
- Advanced safety features, positioning it as one of the safest eVTOLs in development
Market Confidence and Global Interest
The company has secured an impressive 1,500 pre-orders for the VX4, valued at $6 billion. These orders come from a diverse range of customers across four continents, including major players such as Virgin Atlantic, American Airlines, Japan Airlines, GOL, and Bristow.
Looking to the Future
As Vertical Aerospace continues to make strides in eVTOL technology, the company remains focused on its ultimate goal of commercialization.
Vertical, based in Bristol, the heart of the UK’s aerospace industry, stands poised to lead the charge in sustainable aviation.
It was founded in 2016 by Stephen Fitzpatrick, also known for creating the OVO Group – Europe’s largest independent energy retailer.
With each successful test, the company now moves closer to its vision of transforming urban air mobility and revolutionizing the way we travel.
