A vertical take-off and landing fixed-wing aircraft with a canard configuration

Abstract

The invention discloses a vertical take-off and landing fixed wing aircraft with canard configuration, including a body, a main wing is arranged on both sides of the rear part of the airframe, and canard wings arranged on both sides of the front part of the airframe. The aircraft is characterized by a plurality of leading main rotors arranged at the front of the main wing, a plurality of after main rotors arranged at the rear of the main wing. A number of forward ailerons disposed at the front of the canard. A number of after ailerons disposed at the rear of the canard, the junction of the main wing and canard with the airframe can be rotated 90 DEG around the airframe; the invention adopts multiple rotors to realize vertical take-off and landing, and switches between straight flight modeand vertical take-off and landing mode by rotating the rotor driven by the wing. The invention utilizes the advantages of multiple groups of rotors to provide power, abrupt force reduction of the wingrotation, and canard configuration to adjust the center of gravity, and realizes the stable switch and flight of the fixed-wing aircraft with vertical take-off and landing.

Description

technical field [0001] The invention relates to the technical field of vertical take-off and landing aircraft, and more specifically relates to a fixed-wing aircraft with vertical take-off and landing in canard layout. Background technique [0002] Fixed-wing UAVs have the advantages of long battery life, large cruising radius, and high flight efficiency. Using fixed-wing unmanned aerial vehicles as mission platforms to carry various load equipment for flight operations can be widely used in passenger transportation, geographic surveying and mapping, geological exploration and other fields. [0003] However, compared with rotary-wing UAVs, it is difficult to take off and land ordinary fixed-wing UAVs. In terms of take-off methods, large fixed-wing UAVs require a certain take-off speed. Generally, the catapult frame is used to provide a certain initial speed. Therefore, some UAV companies have preliminarily realized the function of fixed-wing vertical take-off and landing by...

Problems solved by technology

[0003] However, compared with rotary-wing UAVs, it is difficult to take off and land ordinary fixed-wing UAVs. In terms of take-off methods, large fixed-wing UAVs require a certain take-off speed, and generally use a catapult to provide a certain initial speed. Therefore, some UAV companies have preliminarily realized the function of fixed-wing vertical take-off and landing by installing several rotors on the fixed-wing wing or on the fuselage. In practical applications, the lack of lift for vertical take-off and landing, and the switch between vertical take-off and landing and horizontal flight have always been technical difficulties, resulting in unstable flight attitude and serious shaking of the fuselage during the switching process, which greatly restricts the performance of vertical take-off and landing.
