Abstract

The invention belongs to the technical field of aviation flight equipment, and discloses a tandem electric double-rotor helicopter and a control system thereof. Rotor devices are longitudinally arranged at the front end and the rear end of a helicopter body; the front and rear ends of the fuselage are flexibly connected with two sets of independent undercarriages, and a container is suspended at the bottom of the fuselage; the control end of the rotor wing device is provided with a control device in a matched mode, the power end of the rotor wing device is connected with a power device, and the rotor wing device and the power device are connected with a control device. Compared with other helicopters, the helicopter body is small in size, simple in structure, large in load capacity, higherin aerodynamic efficiency and insensitive to the gravity center position. The two auxiliary rotors are arranged in a front-and-back longitudinal arrangement mode relative to the helicopter body, andthe overall size of the helicopter body is smaller than that of a single-rotor helicopter with a tail rotor, a double-rotor helicopter with a transverse arrangement mode and a multi-rotor helicopter with multiple rotors. Compared with the same conventional helicopter with rotors provided with tail rotors, the novel helicopter with two basically same rotors is adopted, and the take-off weight larger than two times of the take-off weight of the helicopter can be obtained.

Description

technical field

[0001] The invention belongs to the technical field of aviation flight equipment, and in particular relates to a tandem electric double-rotor helicopter and a control system thereof. Background technique

[0002] At present, the commonly used prior art in the industry is like this: the outstanding feature of helicopter is to do maneuvering flight at low altitude, hovering, low speed and nose direction constant, especially vertical take-off and landing at small area sites. Based on these characteristics, helicopters are widely used in military and civilian applications, and have strong versatility between military and civilian use. Helicopters generally include fuselage, landing gear, rotor device, control device, power device, control device, etc. Helicopters can generally be divided into single-rotor with tail rotor type, double-rotor type, and multi-rotor type according to the rotor structure.

[0003] The single-rotor with tail rotor type is the most com...
