Problems solved by technology

[0011] Different from the tilting rotor, the tail seat UAV system has a simple structure, can meet the minimum requirements for the landing area, and can take off and land vertically and hover in the air. controlled situation
Because it has a large airfoil, most of the reasons for its instability are the interference of external airflow, especially in the hovering state, the airfoil in the wind area can easily cause a large disturbance moment, which will cause the aircraft to Uncontrollable attitude deflection

Abstract

The tandem vector thrust full-drive aircraft and its design method relate to the technical field of aerospace. The front vector actuating mechanism is respectively connected with the front connecting mechanism and the front electric thrust system to form a front thrust vector actuating mechanism. The moving mechanism is respectively connected with the rear connecting mechanism and the rear electric thrust system to form a rear thrust vector actuating mechanism. The rear connecting mechanism is connected with the rear end of the body. The invention can realize the vertical take-off, landing and hovering of the aircraft, and has strong application flexibility. In addition to the vertical flight mode, it can be mounted on a fixed wing for horizontal flight, taking into account the requirements of speed and efficiency for long-distance flight. Near the working point is a full-drive system, which can directly generate lateral control force without attitude deflection, and directly perform position translation, with strong anti-interference ability and high maneuverability.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a tandem vector all-drive aircraft and a design method thereof. Background technique [0002] At present, for the structure of special-shaped aircraft, it mainly includes tailstock type, tilting fuselage type, tilting rotor type, etc. Among them, the tilting rotor and tilting fuselage type are relatively difficult to realize due to the need for complex rotating mechanisms. The existence of the structure leads to the limitation of its speed during level flight, making it impossible to achieve high-speed flight. For the tail seat aircraft, due to its large wing surface, the environmental factors, especially the wind factors, are relatively high during take-off and landing. Once the wind speed is high, the aircraft will not be able to take off and land smoothly. landing. [0003] In addition, currently small UAVs use an underactuated structure to control the UAV. If it is neces...
