fixed-wing vertical take-off and landing aircraft

Abstract

A design scheme resides in addition of a pair of long and new wings (named as flanks) on basis of common fixed wings, wherein the flanks are parallel to an aircraft body, and are slightly downwards connected and fixed on the left and right sides of the aircraft body. Main wings are connected to externals sides of the flanks. Air flow is accelerated by a plurality of centrifugal blowers in the aircraft body, and is high-speed sprayed out from upper and lower surfaces of the flanks at two sides of the aircraft body. A turbine engine with a rotatable jet pipe is installed on the tail of the aircraft body. The design scheme simulates an air flow state when the aircraft horizontally slides on the flanks when vertical take-off, and fully utilizes air flow lift. The fixed wing vertical takeoff and landing aircraft has advantages of energy saving, high efficiency, simple structure, simple control, and stable transition and fast speed from vertical lifting to a horizontal flight attitude, can implement hover and turning motions, is balanceable and stable when vertical takeoff and landing, and is especially suitable for short-distance gliding takeoff. The fixed wing vertical takeoff and landing aircraft is used in an aviation flight field, and is suitable for an unmanned plane, a private plane, a business plane, a fighter, etc., especially for a naval fighter.

Description

technical field [0001] It is used in the field of aviation flight, such as military aviation and civil aviation. Suitable for such as: drones, private jets, business jets, fighter jets, etc. Especially suitable for carrier-based fighters, etc. Background technique [0002] Compared with helicopters, fixed-wing aircraft mainly have the advantages of fast speed, good maneuverability, and low energy consumption. But the disadvantage is that the landing site is limited and requires a long runway. Helicopters, on the contrary, can hover, sail at low speeds, and are not restricted by take-off and landing sites. Therefore, the characteristics of fixed-wing aircraft compatible with helicopters are the final development direction. [0003] At present, there are mainly two vertical take-off and landing methods for fixed-wing aircraft, one is the propeller steering method, and the other is the turbine vertical jet method. However, these two methods have some insurmountable shortco...

AI Technical Summary

Problems solved by technology

However, these two methods have some insurmountable shortcomings, such as: complex structure, complex control, high power consumption, poor balance, complex transition from vertical to horizontal attitude and slow transition speed, etc.

Therefore, it has not been widely used
