Vertical Aerospace Begins Testing OnNew VX4 Prototype
London, UK; New York, USA - 22/07/2024•

Testing for the new, more advanced VX4 prototype has begun with initial powered
ground tests, including propeller balancing, complete at Vertical’s Flight Test Centre.

•Vertical will now conduct powered, propulsion testing ahead of “wheels up” phase withpiloted flights, once the UK Civil Aviation Authority (CAA) has issued its Permit to Fly.

Vertical Aerospace (Vertical) [NYSE: EVTL], a global aerospace and technology company
that is pioneering zero emissions aviation, today announced that testing on its mostadvanced eVTOL aircraft, unveiled last week, has started with initial powered ground tests,
including propeller balancing, successfully complete.
Propeller balancing and spinning tests measure weight distribution of each propeller blade
to ensure vibrations are minimised for smooth, stable flying.

Press Release 22 July 20241Over the coming days, the company will conduct powered, propulsion system testing of its
most advanced powertrain, which includes proprietary battery packs capable of producing
1.4 MW of peak power and has been designed, and built to certification safety standards at
its multi-million-pound Vertical Energy Centre.
These next tests involve securely anchoring the aircraft to prevent lift-off and runningthe engines at various power levels to measure thrust output, system integration, andstructural integrity. Together, these tests will ensure the VX4 meets the highest standardsof operational safety which are needed for piloted flights.
The company will then move onto its “wheels up” phase with tethered flight tests before
progressing to low-speed untethered flights, once it has been issued its Permit to Fly fromthe UK Civil Aviation Authority (CAA).

David King, Chief Engineer, Vertical Aerospace, said:“These tests are a crucial step forward in our mission to certify the VX4 and make a cleaner,
quieter, and safer way of air mobility a reality. Every day we are seeing amazing progressfrom the team at our Flight Test Centre, each test providing valuable insights to help shape
the next. We continue to work alongside our regulator to develop the safest and mostadvanced eVTOL aircraft in the world.”
As the aerospace world meets in Farnborough this week, we could not be prouder of theteam and look forward to sharing more on our progress towards piloted flights.”
This next-generation VX4 is more powerful than the previous full-scale prototype, with animpressive 20% increase in the power to weight ratio, enabling the aircraft to reach speedsof up to 150mph – the certification aircraft’s intended cruise speed.
The aircraft has been designed and built alongside global aerospace partners, including
GKN Aerospace, Honeywell, Hanwha, Molicel, Leonardo and Syensqo. It features Vertical’s
next generation propellers and new proprietary battery technology, designed andmanufactured at its multi-million pound state-of-the-art Vertical Energy Centre near
Bristol, the UK’s most advanced aerospace battery facility.

NOTES TO EDITOR
Piloted flight test programme explainer:•••••

Tethered: the VX4 will perform stabilised hover while loosely tethered to the ground.
Untethered: the VX4 will hover without a tether.
Thrustbourne: the VX4 will take-off and land vertically and conduct low speed flightmanoeuvres with lift generated by the propellers.
Wingbourne: the VX4 will take-off, fly and land like a conventional aircraft, with lift
generated by the wing.
Transition: The VX4 will transition between thrustbourne and wingbourne flight, andvice versa.
