PALV - Personal Air And Land Vehicle

The PALV (Personal Air and Land Vehicle) is a concept for a flying car, which utilizes autogyro flying technology. In fact, the PALV is a cross-breed between a car, a motorcycle and a gyrocopter, and is designed to eliminate limitations in either flying or driving mode. The vehicle is under development by the Dutch entrepreneur John Bakker in close cooperation with the Dutch company Spark Design Engineering and other partners. Take a look at pictures of this cool concept air car:
The design of the PALV is based on the three-wheeled road-going production vehicle Carver One from the Dutch company Carver Europe. The Carver One has a fully enclosed cabin with two seats placed behind one another. The rear wheels are incorporated into one unit together with the engine and gearbox. The cabin is attached to the rear unit by a mechanical-hydraulic system. The Dynamic Vehicle Control (DVC) automatically tilts the cabin, depending on the steering input, speed and acceleration of the vehicle, much like a motorcycle.
The same system and general cabin layout is used for the PALV. On the road, the PALV can reach speeds of 200 kilometres per hour (125 mph).
For flying mode, the vehicle is fitted with a single foldable rotor on top of the cabin, a single foldable push propeller at the rear of the cabin and a foldable tail-wing section. By folding out the rotor blades, propeller and tail-wing section, the PALV is able to take to the skies with autogyro flying technology.
Forward speed is produced by the rear propeller, which is driven by the same engine that drives the wheels in road-mode. Within a takeoff run of just 50 metres (165 ft), the PALV is lifted into the air by the foldable rotor on top of the cabin. This rotor auto-rotates due to the forward speed and generates lift. Because of the slower auto-rotation, as well as the absence of a tail rotor, the PALV is much quieter than a helicopter.
The PALV is designed to fly under the 1,500 metre (4,000 ft) floor of commercial air space. This makes it possible to take off at any time, without a flight plan, from the nearest airfield or helipad. Much like a helicopter, the PALV has a Very Short Take Off and Vertical Landing (VSTOVL) capability, enabling it to land almost vertically within a distance of just 5 metres (16 ft). The autogyro technology furthermore enables a safe landing even when the engine fails, as the vehicle descends vertically instead of nose-diving.

At last! a vehicle that challenges the gas guzzling American V8 hot rod. If you can convert the speed and danger hungry, dare to die, ballsy American male to chasing around the country side in one of these, and power it with bio-diesel too, you will have contributed greatly to solving the oil crises in the world.
Put skis on it and we could land it on ski-doo trails and small lakes here in Canada for about 50% of the year, and with floats we could get to fishing sites in the summer like never before!
Good Show!
It would cost thousands of dollars to get a license for it. There is no such thing as a floor of 4,000 feet for commercial airspace. (at least not in the U.S.) As for replacing a V8 hot rod, I don’t foresee that happening cause people just can’t hop into an aircraft and fly, it takes hours of experience and lots of practice before the FAA deems you safe enough to operate an aircraft by yourself. There is much to flying that the average person doesn’t realize or know about. This would be terrible for the General Aviation Community.
It blurs boundaries between land and air transport so there would have to be a new type certificate issued for this hybrid vehicle, 10 years of certification I would estimate. After buying and training only millionaires would be able to afford this and they would soon be dead millionaires, without extensive training and safety features such as the SR-22 parachute system that let aircraft float back to earth when the pilot becomes disoriented. Personally I think this is a pipe dream without unprecedented airspace and civil infrastructure reforms. Spend the money on education and health care instead, not hobbies for the rich and bored.
