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.

Terminator-like entities haunt the grounds:

 Wicked-looking battle bots and robot crawlers lurk in the garage, the walking cannons scurry around like mechanized chickens:

 Imagine meeting this thing somewhere in the country field in the middle of the night… You just might become a connoisseur of “grotesque” for the rest of your life.

Aptera - Aerodynamic Three Wheeler

The American company Accelerated Composites aims to keep the design of its Aptera concept car even closer to an aerodynamic ideal shape. The company claims to be able to achieve a drag coefficient of less than 0.06 using a highly unconventional aerodynamic body shape. Combined with a lightweight composite construction, the Aptera should achieve a fuel consumption as low as 0.7 litres per one hundred kilometres (336 mpg US).

The styling of the Aptera concept car shows more resemblance with airplane than with car design. The car has a wide front with two separate front wheels and a tapered rear section with one, fully enclosed rear wheel. Because of the very low drag, the Aptera is equipped with movable fins on the back to create active aerodynamic stabilization at high speeds.

The Aptera will be equipped with a parallel hybrid-electric propulsion system.
The first prototype of the Aptera is under constructed during 2006. Accelerated Composites is planning production in Southern California, which could start as early as 2008.

TECHNICAL SPECIFICATIONS
DRIVE SYSTEM: Parallel hybrid-electric + combustion engine
POWER OUTPUT
Diesel engine: 9 kW (12 hp)
Electric motor: 18.6 kW (25 hp)
FUEL: Diesel
FUEL CONSUMPTION: 0.7 l / 100 km (335 mpg US)
MAXIMUM SPEED: 155 km/h (95 mph)
ACCELERATION 0-97 KM/H (60 MPH): 11 sec.
