Vertical takeoff and landing aircraft achieving simple structure and stable operation

Abstract

The invention discloses a vertical takeoff and landing aircraft achieving simple structure and stable operation. The aircraft comprises a fixed wing and a fuselage, wherein the fuselage is provided with a suspension arm; the fixed wing is mounted at the top end of the suspension arm; the fixed wing is provided with more than three power rotors; the rotation axis of at least one of the power rotors and the rotation axes of the remaining power rotors are positioned on different planes; the power rotors are fixedly mounted on the fixed wing through power rotor mounting arms; and each power rotor mounting arm is further provided with an engine for driving the power rotor to rotate. The vertical takeoff and landing aircraft achieving simple structure and stable operation further comprises an undercarriage, wherein the undercarriage is mounted on the fuselage. The vertical takeoff and landing aircraft is low in research and development difficulty, low in cost, simple in structure, low in cost, convenient to maintain and long in duration of flight, and can easily ensure the reliability.

Description

Technical field [0001] The invention relates to the technical field of aircraft, in particular to a vertical take-off and landing aircraft with simple structure and stable operation. Background technique [0002] There are currently two main types of vertical take-off and landing fixed-wing aircraft: [0003] 1. In the take-off and landing phase, lift fans, rotors, tilting wings, or deflection nozzles are used to provide lift and attitude control, the cruise phase is switched to horizontal thrusters to provide cruise thrust, fixed wings provide lift, aerodynamic control of the rudder surface, vector thrust or cycle The variable pitch propeller provides attitude control. [0004] 2. The vertical take-off and landing scheme with the tail landing on the ground is adopted to allow the aircraft to take off and land upright. In the air, the aircraft can be turned into level flight through pneumatic control surfaces, periodic variable pitch propellers or differential thrust. [0005] The fi...

Problems solved by technology

[0005] The first type of vertical take-off and landing fixed-wing aircraft needs to have two sets of control methods and switching logic for take-off and landing and cruise at the same time. It is difficult to develop and costly, and it is difficult to guarantee the reliability of work.

In addition, due to the need to have two different power systems and control mechanisms for takeoff and landing and cruise at the same time, the structure is complex and the weight is heavy, which increases the energy consumption of flight

[0006] The second type of vertical take-off and landing fixed-wing aircraft needs to be pitched forward and backward by 90° in order to switch between take-off and landing. Data collection equipment that needs to work continuously during takeoff and landing and in flight will have orientation problems

In addition, because this type of vertical take-off and landing fixed-wing aircraft has a large windward area during take-off and landing, it cannot take off and land when the wind speed is high.
