Aerodynamic/thrust vector combined control type tail-sitter unmanned aerial vehicle

Abstract

The invention discloses an aerodynamic / thrust vector combined control type tail-sitter unmanned aerial vehicle. The tail-sitter unmanned aerial vehicle is characterized by comprising a body, rotor engines, elevons, steering engines and undercarriages. The rotor engines are mounted at the tail of the body, the steering engines are mounted on inner sides of the rotor engines and control the elevonsthrough steering engine rocker arms which drive pull rods, the elevons are mounted under the rotor engines, and the carriages are mounted on two sides of the body. When the unmanned aerial vehicle isin a post-stall flight state, by deflection of the elevons, thrust sector control is realized through high-speed flip flow generated by the rotor engines, and control capability of the elevons is improved; in a high-speed level flight state, aerodynamic control is realized mainly through deflection incoming flow of the elevons, and cruising flight efficiency is improved. The unmanned aerial vehicle is simple in structure, safe in use and high in attitude control performance and integrates vertical take-off and landing and efficient cruising performance, thereby being suitable for popularization and application.

Description

technical field [0001] The invention belongs to the field of aircraft design and relates to aircraft configuration design, aerodynamic efficiency analysis and safety design. Background technique [0002] Tailseat UAVs have been extensively studied in recent years because they have both the vertical take-off and landing functions of rotor UAVs and the high-speed cruise capabilities of fixed-wing UAVs. At present, there are many types of tailstock unmanned vehicles that have been studied at home and abroad: [0003] 1. Single rotor (rudder surface control) [0004] This type of tail seat UAV is generally improved on the basis of the existing fixed-wing UAV (such as adding landing gear, increasing engine power, etc.). The disadvantage is that the flight endurance is limited due to the limited power provided by the single rotor. Weak capability; when hovering, due to the loss of propeller slipstream and the limited residual rudder deflection of the ailerons after counteracting...
