Vertical Aerospace has unveiled its second full-scale prototype of the VX4 eVTOL aircraft, marking a significant milestone ahead of its planned flight testing. The UK-based company released images of the newly completed aircraft on Thursday and announced that it will commence flight tests once the UK Civil Aviation Authority (CAA) grants a permit to fly.
The new prototype incorporates substantial changes from an earlier version used for flight tests since August. Vertical stated that 60% of the technology and components in this latest model have been provided by key partners, including GKN Aerospace, Hanwha, Honeywell, Leonardo, Molicel, and Synesqo.
A notable update is the redesigned propeller system. This change stems from lessons learned following an accident on August 9, 2023, which severely damaged the first prototype. According to Vertical, the aerodynamic shape of the new propellers is optimized for both hover and cruise phases by balancing their distinct requirements.
