Abstract

The adopted technical scheme of the invention is a direct-driven type oil-driving fixed-rotating-speed propeller pitch changing multi-rotor unmanned aerial vehicle and a controlling method thereof. The direct-driven type oil-driving fixed-rotating-speed propeller pitch changing multi-rotor unmanned aerial vehicle comprises a vehicle body, a power system, a landing gear and an avionic system. The vehicle body is a total complex material integrated vehicle body. The power system is composed of engine systems, propeller pitch changing systems, an oil supplying system and rotor systems. The landing gear is a skid landing gear. A flexible hoisting position is arranged on the landing gear to be fixedly connected with different task devices. A driving mechanism is not needed, the structure is simple, and the weight is reduced relatively by 10%-20%. Lifting force is adjusted through a propeller pitch changing angle, the abrasion of an engine is small, and the life is prolonged by 30% or above. The vehicle body adopts nested-type placement. The oil supplying system, a power supply system, a spraying system and the like are arranged inside the vehicle body, so that the space utilization rate is improved, and waste resistance is reduced.

Description

technical field [0001] The invention belongs to the technical field of oil-driven multi-rotor UAVs, and in particular relates to a direct-drive oil-driven multi-rotor UAV with fixed speed and variable pitch and a control method thereof. [0002] technical background [0003] Generally, UAVs are divided into unmanned fixed-wing, unmanned helicopter, unmanned multi-rotor, unmanned airship, unmanned paraglider and unmanned flapping wing. The first three types are the most common and widely used. Unmanned fixed-wing flight has the highest efficiency, long battery life, and high cruising speed, but it needs a runway, cannot hover in the air, and has the worst maneuverability; unmanned helicopters can take off and land vertically, hover in the air, have the best maneuverability, and have a long flight time and The load is heavy, but the structure is the most complex and the cost is the highest; the unmanned multi-rotor has the simplest structure, the easiest operation, strong fault...
