The Helicron is an open-wheel car that used a propeller as its drive. The Helicron was abandoned in the late 1930s, but was restored after its barn find in 2000. [1] In the same year, the car was permitted by the French government to drive on the French roads. [2] The car currently resides in the Lane Motor Museum and is on display, as a ...
For small-scale quadcopters, this makes the vehicles safer for close interaction. It is also possible to fit quadcopters with guards that enclose the rotors, further reducing the potential for damage. [2] However, as size increases, fixed propeller quadcopters develop disadvantages relative to conventional helicopters.
A brushless, geared inrunner motor in a quadcopter. The term inrunner refers to an electric motor where the rotor (runner) is inside the stator. The term is in particular used for brushless motors to differentiate them from outrunners that have their rotor outside the stator. The vast majority of electric motors are inrunners.

Rotor-powered vehicles are wind-powered vehicles that use rotors—instead of sails—which may have a shroud around them or constitute an unducted propeller, and which may adjust orientation to face the apparent wind. The rotor may be connected via a drive train to wheels or to a generator that provides electrical power to electric motors that ...

A screw-propelled vehicle. A screw-propelled vehicle is a land or amphibious vehicle designed to cope with difficult terrain, such as snow, ice, mud, and swamp. Such vehicles are distinguished by being moved by the rotation of one or more auger-like cylinders fitted with a helical flange that engages with the medium through or over which the vehicle is moving.
A pusher aircraft is a type of aircraft using propellers placed behind the engines. Pushers may be classified according to lifting surfaces layout (conventional or 3 surface, canard, joined wing, tailless and rotorcraft) as well as engine/propeller location and drive. For historical interest, pusher aircraft are also classified by date.
On the road, most flying cars drive the road wheels in the conventional way. A few use the aircraft propeller in similar manner to an airboat, but this is inefficient. In the air, a flying car will typically obtain forward thrust from one or more propellers or ducted fans. A few have a powered helicopter rotor. Jet engines are not used due to ...
