Hover Landing Gear

Fixed wing flight is the fastest way to travel across long distances, and is the most efficient form of flight, producing 10X the lift of rotors. But fixed wing flight requires a long runway for a long rolling takeoff and long rolling landing, in order to transition from standstill to flight velocity with sufficient lift, and vice-versa.

Instead of landing gear that's primarily designed to roll, we need landing gear whose primary purpose is to lift the fixed-wing aircraft off the ground to transition it to forward flight (and vice-versa, to transition it from forward flight to standstill on the ground)

We will use the usual combustion engine to power our usual fixed-wing forward flight, to travel from departure point to destination point. But we will use electric motors to power our hovering VTOL "landing gear", which consists of rotors. This is because electric power can more easily provide distributed power to multiple points on the aircraft, to help it hover for transition purposes. Electric power has low storage density, but we expect our takeoff & landing to be of brief duration, as contrasted with the longer duration of the forward flight travel from departure point to destination point, which will be done by standard fuel-powered combustion engine.

The electric power could be supplied by a dynamo/generator attached to our combustion engine shaft, supplemented by a not-too-heavy battery. Takeoff procedure would obviously require starting the main combustion engine to provide current to power the electric rotors.

The main transit portion of the flight would use a regular axially-aligned propeller driven by the combustion engine. But the rotors used for the takeoff & landing portions of the flight could themselves be cycloidal rotors. Cycloidal rotors are able to modify their thrust axis dynamically (see link)

Just as regular landing gear can be retracted into the body of the aircraft during transit, likewise these liftoff & touchdown rotors would also be retracted during transit.

Finally, even though this landing gear is not meant for rolling takeoffs or landings, it would have some small token wheels to facilitate ground towing. An aircraft so equipped would however typically be expected to hover out of or into its parking spot.
