Electric Aircraft Design: Rolls Royce "Spirit of Innovation"

 Registration is closed for this event
A FREE IMechE talk for the public by John Wighton - Managing Director of Acroflight Ltd

Acroflight's current client portfolio includes the Rolls Royce ACCEL electric aircraft programme. From 2018 Acroflight's role was to contribute to the aircraft design, perform engineering analysis(stress) and create verification reports leading to releasing the flight readiness documents. The Rolls Royce ACCEL is a 7.3mtr(24ft) span aircraft powered by three high power density electric motors driving a single three blade propellor spinning at 2,400 rpm. Battery output power will be 500hp(375kw) continuous, reaching 750kw (1,010 hp) at maximum power. It is designed to have the highest energy density for an aircraft and should allow a 310km range.

John's career began at British Aerospace (Hatfield) where he completed an Undergraduate Apprenticeship. He joined the Stress Office working on TA9/10 (A330/A340) Airbus wings, HS125, BAe 146 at which time he realised a passion for engineering analysis. He worked at HW Structures as an analyst and thereafter, in 1988 created his first business to bring computational methods (FEM/FEA) to companies who could not afford (or understand) how to use them. He set up a JV with GE Plastics [design division] which led to rapid growth in the deployment of engineering thermoplastics across a wide industry base. Divesting ownership of that company in the mid-'90s allowed him to re-focus on specific capabilities in aerospace and automotive product development. The company achieved UK CAA Design Organisation Approval in the early 2000s. Acroflight's current client portfolio consists of SME, start-ups (eVTOL) and research projects, such as involvement in the Rolls Royce ACCEL electric aircraft program.

Refreshments will be available from 30 minutes before the advertised start time.
