Cranfield Aerospace receives UK grant for development of electric flight

Cranfield Aerospace Solutions (CAeS) has received the backing of the UK Government for a project to develop electric aviation. Coined ‘Project Fresson’, CAeS has received a grant of £9 million to design, manufacture and integrate a hybrid-electric propulsion system into a 9-seat Britten-Norman (B-N) Islander aircraft, which is typically used on short flights such as island-hopping routes.

CAeS announced that the grant is provided through the ATI Programme: a partnership of the Aerospace Technology Institute (ATI), the Department for Business, Energy & Industry Strategy, and Innovate UK. Mark Scully, Head of Technology for Advanced Systems & Propulsion at the ATI, said: “Project Fresson brings together a partnership to develop innovative technology for a sustainable all-electric air transport solution for isolated islands. The partners’ ultimate goal of delivering the first commercial passenger-carrying all-electric aircraft service in the UK will mark a significant breakthrough for all-electric propulsion.”

According to CAeS, the Project Fresson team is comprised of several UK businesses: Rolls-Royce, who will be supplying the power management system; the Denis Ferranti Group, supplying the electric motors; Delta Motorsport, providing battery packs; WMG (University of Warwick), who will perform battery testing and characterisation, and Britten-Norman, the aircraft OEM (Original Equipment Manufacturer) providing the baseline aircraft and aircraft data/design support. CAeS parent Cranfield University will be researching key technology solutions vital for the 30-month project.

Paul Hutton CAeS CEO, said: “The results of this exciting electric aircraft demonstrator project can be rapidly developed into an EASA/CAA (European Aviation Safety Agency/Civil Aviation Authority) certified modification kit, enabling the UK to lead the way with the first passenger-carrying sub-regional aircraft capable of all-electric flight. The strength of the industrial partners involved in this project, are underpinned by the world-class aerospace/manufacturing research capabilities of Cranfield University. This is going to accelerate our green transport revolution.”

Following the demonstrator project, CAeS will go on to certify the modification through EASA to obtain a Supplemental Type Certificate. This will then be immediately available in the global market, allowing the current operators of B-N Islanders to convert their aircraft reducing operating costs and carbon footprint.

In follow-on phases of CAeS’s green aircraft strategy the intention is to design and implement a similar modification, this time to a larger existing 19-seat sub-regional aircraft type, continuing with partners to design and build a new 19-seat aircraft. The design of the new aircraft will be optimised for emission-free propulsion, described by CAeS, making use of the certified propulsion systems architecture from the earlier phases.
