today unveiled its ‘Project Zero’, an electrically-powered tilt rotor technology demonstrator, giving an insight into what advanced of the future may look like. The company funded technology demonstrator was designed and built in less than 6 months and has already secretly flown several times in 2011 and 2012.
An electric powered vehicle, ‘Project Zero’ can hover like a helicopter and convert to a fixed wing aircraft in forward flight thanks to its two integrated rotors, which can be tilted through more than 90 degrees. The demonstrator performed its first unmanned tethered flight in June 2011 at’s Cascina Costa facility in Italy and has since performed untethered hovering flights inside a secured area.
Daniele Romiti,’s CEO, said “The ‘Project Zero’ technology demonstrator program brings together many of the advanced technologies AgustaWestland has been researching in recent years and demonstrates our strong technological base from which we will develop new products to meet the needs of our customers in the future. We strongly believe in the tilt rotor concept as the future of high speed flight as it offers much greater speed and range than compound helicopter technology.”
The demonstrator’s rotors are driven by advanced electric motors powered by rechargeable batteries; future hybrid solutions have also been investigated using a diesel engine to drive a generator. All of the aircraft control systems, flight control and landing gear actuators are electrically powered, removing the need for any hydraulic system.
During cruise, the wings will provide most of the lift, with the blended fuselage and shroud also making a contribution. ‘Project Zero’ has been designed with detachable outer wings for missions that will be performed primarily in helicopter mode. Elevons provide pitch and roll control in forward flight while the V-tail provides longitudinal stability. The aircraft has very low noise and thermal signature in flight and does not require oxygen, thereby permitting it to fly at altitude or in heavily polluted conditions, such as volcanic eruptions.
When parked on the ground the rotors can be tilted forward, with the the aircraft pointed into wind, to allow the rotors to windmill and recharge the aircraft’s electrical storage device. The electrical drive system also has the advantage that it does away with the complex and heavy transmission system required by conventional.
