Design and developmentEdit
Slovak designer Professor Štefan Klein began working on flying cars in the late 1980s. Having developed the AeroMobil, he left the company to develop a new idea as the AirCar, and set up Klein Vision with colleague Anton Zajac.
The main fuselage of the AirCar doubles as a two-seat road car with four large road wheels. Styled like a sports coupe, it contributes 30-40 per cent of the total lift when in the air. For flight it is fitted with foldout wings and extending tailbooms carrying a high tail. A pusher propeller is permanently installed between the fuselage and tail, and a safety parachute is installed. Construction is primarily a semi-monocoque of carbon fibre composite over a steel subframe. Over 20 programmable servo motors are used to perform the transition between road and air configurations. When on the road, the retracted tail surface creates a downforce similar to conventional rear aerofoils.
Power is provided by a 1.6 litre BMW road car engine, running on automotive petrol or gasoline and delivering 104 kilowatts (139 hp).
The prototype takes off at around 120 kilometres per hour (75 mph), after a run of 300 metres (980 ft). Cruising speed in the air is said to be 170 kilometres per hour (92 kn) Range is estimated as 1,000 kilometres (620 mi), at a height of 2,500 metres (8,200 ft). The current version of the car can reach heights of 4,572 metres (15,000 ft). It is said to take two minutes and 15 seconds to transform from car into aircraft.
