Page 16 of 67 17 forward flight. Initially, the aircraft will be flown by a pilot, but it could eventually become pilot-less. The intermediate design could be adapted for personal and public transport, logistics, and military applications and is based upon technologies that already exist or are currently under development. It could enter service in the early 2020s we’ve been told assuming collaboration with airframers and a range of strategic partners for aspects of the electrical system. The EVTOL wings are able to rotate 90 degrees, enabling the vehicle to take off or land vertically. The propellers on the wing would fold away once the craft has reached cruising height, reducing drag and cabin noise, with the craft relying on two rear propellers for horizontal flight thrust. Accelerating the Electrification of Flight ACCEL Rolls-Royce is leading a research project known as Accelerating the Electrification of Flight (ACCEL) to explore the use of a high power electrical system in a demonstrator aircraft. They are working with YASA, a UK manufacturer of high-power, light weight electric motors and controllers used in automotive, aerospace, and industrial applications. A 12-foot carbon fiber airplane chassis which has been built combining Formula E auto racing and high-power battery development was exhibited in the Innovation Zone. Once complete, this plane will be the centerpiece of Rolls-Royce’s ACCEL initiative and it will be all electric. In a way it shows a new way of working at Rolls-Royce. The ACCEL team plans to build, test, and commercialize this product in a short timeframe. The ACCEL initiative, short for accelerate, will use funding from the UK’s Aerospace Technology Institute and involves a host of UK partners including electric motor and controller manufacturer YASA and Electroflight Ltd. The Rolls-Royce digital team will be in the cockpit with them, running the data analytics and performance modeling. ACCEL plans to set new records for time to climb for an electrically powered aircraft, and highest voltage and highest power density achieved for an aircraft battery system. Almost no technical data was disclosed and Cervenka was underlining that this airplane should not be understood as a model, and the purpose is to YASA DISPLAYED a 12-foot carbon fiber airplane chassis that is part of Rolls-Royce's ACCEL project.
