CEA Electric Helicopter medium-lift passenger concept design rotorcraft with NOTAR technology
The CEA Electric Helicopter is a futuristic sleek medium-lift passenger concept design rotorcraft with NOTAR technology concept design. The CEA means Czech Experimental Aircraft. NOTAR means NO TAil Rotor. NOTAR technology was developed by McDonnell Douglas Helicopter Systems and the company is now called MD Helicopters. The aircraft holds one pilot and carries four passengers. The helicopter can have two pilots in the cockpit if they choose to. The helicopter holds a total of five people.

While most specifications have not been estimated by the designer, the helicopter has five rotorblades with swept angled tips. The swept angled tips are for added performance during high-speed flight. The helicopter also uses NOTAR (no tail rotor) technology to keep the helicopter in the direction the pilot desires. MD Helicopter's five bladed MD 500 helicopter has a long track record for being very stable in flight, even in slightly windy conditions, which is why MD 500 helicopters are the typical choice for powerline maintenance.

The helicopter's fuselage has been made from carbon fiber composite material for a high-strength low weight ratio. The rotorcraft has been design with large windows to provide excellent views for the pilots and passengers. The helicopter has fixed skid landing gear. If you notice, this fixed skid landing gear is a new rear design that has never been used on a helicopter, as far as we know. In case of a power failure, the pilot can autorotate the helicopter and land the helicopter to safety.
