Electrotor

	ELECTROTORS
	ELECTROTORS

Electrically Driven Principal Assemblies, for Bilateral Rotor UAVs, ULRs and Future PAVs.

Electrotor - Simplex;

A simple arrangement, for development purposes.

Electrotor - SloMo;

No gearbox. It uses an axial-flux motor that has a one to one ratio with the rotorhead.

Incorporates a 3-blade rotor c/w a Constant Velocity Joint and Hub Spring for greater control.

Electrotor - Plus;

Incorporates a 2-blade teetering rotor, however the hub has enhanced control; due to the gyroscopic precession of a high speed, high inertia motor.

General Notes:

Unmanned Arial Vehicle (UAV); with Interleaving or Side-by-side Configuration:

The induced velocity distribution throughout the total disk area should be quite good, particularly during forward flight. This is because the UAV has no need for a central fuselage. There would be a pod below both rotor hubs. In these two pods could be located the engine(s) power trains and payloads. The ABC and ARR should improve the induced velocity distribution. There is no need for active blade twist unless the craft is eventually intended for high speed forward flight.

Extended Flight: Where warranted, bundling the battery packs in a number of groups could extend the flight time. When a group is discharged that group could be jettisoned from the craft to reduce the gross weight.

Miscellaneous General Information: To eventually be moved to separate page.
