Vertically-lifted fixed wing aircraft with balancing mechanism

Abstract

The invention discloses a vertically-lifted fixed wing aircraft with a balancing mechanism. The vertically-lifted fixed wing aircraft includes a fuselage, tail wings, power devices with tilting mechanisms and a balancing mechanism, and the power devices with the tilting mechanisms include fixed pitch propellers, engine nacelles, slipstream rudders, wings, tilting wings and steering engines; the engine nacelles are internally provided with engines which are connected with the fixed pitch propellers and the balancing mechanism; one ends of the tilting wings are fixedly connected to the engine nacelles, and the other ends of the tilting wings are rotatably connected to the wings; the slipstream rudders are movably connected to the tilting wings, and the steering engines drive the slipstream rudders; the power devices with the tilting mechanisms are symmetrically arranged on both sides of the fuselage and horizontally arranged with the wings; the head of the fuselage is provided with a through hole, the through hole is internally provided with a ducted fan; and the balancing mechanism is arranged inside the fuselage to maintain balance of the fixed wing aircraft. According to the vertically-lifted fixed wing aircraft with the balancing mechanism, the lifting inertia is small, running stability is good, and fuel consumption is low.

Description

technical field [0001] The invention relates to the technical field of aircraft, and more specifically relates to a vertically ascending and descending fixed-wing aircraft with a balancer set. Background technique [0002] Since the 21st century, more and more aircraft developers have turned their attention to fixed-wing aircraft that take off and land vertically. This type of aircraft has similar functions to helicopters and can take off and land vertically without using a runway. The difference is that this This type of aircraft can accelerate from a hovering state to level flight through power tilt and transition to a fixed-wing flight mode. [0003] At present, practical vertical take-off and landing fixed-wing aircraft are mainly AV-8 Harrier fighter jet, V-22 Osprey tilt-rotor aircraft, and F-35 fighter jet. The AV-8 Harrier fighter uses a Pegasus engine, and on the basis of a jet engine, it adopts a thrust reversing scheme with a rotatable exhaust nozzle. In actual u...

Problems solved by technology

[0004] However, since the V-22 Osprey uses two helicopter rotors, in the vertical take-off and landing mode, the rotors need an automatic tilter to control the stability of the attitude of the aircraft, which increases the difficulty of control, and the blades use a periodic pitch change device, which also increases In addition, in the vertical take-off and landing mode of the Osprey, the rotor slipstream blows directly on the wing surface, causing a large pressure drop resistance loss, and forcing the wing to increase the structural strength, which in turn increases the structural weight of the aircraft and reduces the aircraft performance

[0005] However, in order to balance the lift of any machine that needs to be lifted vertically, it is generally necessary to rely on a certain balance system. The balance systems used in the prior art include: a traditional mechanical balance mechanism, which has a lifting inertia Large, single speed, poor running stability, unable to meet the needs of the performance of the machine itself; or use an engine specially equipped with a balance system, although it can make the vertical lift maintain a basic balance during vertical take-off, but rely on this system to realize the vertical lift of the aircraft, Not only the fuel consumption is high, the voyage is short, and the combat radius is small, but also the elevator where the system is installed needs to carry more fuel, and its maneuverability is also poor
