Problems solved by technology

[0003] Since the invention of rotorcraft such as helicopters, it has played a huge role in the field of military and civil aviation. Because the rotor is used to provide lift, it has excellent hovering and low-speed performance, which is its advantage compared with fixed-wing aircraft. Providing lift and overcoming the resistance of forward flight also limits the increase of its flight speed. It is difficult to achieve the higher speed and longer range that fixed-wing aircraft can achieve, which is not conducive to expanding its application field
At the same time, the flight principle of fixed-wing aircraft determines that it is difficult to hover, and lacks low-altitude and low-speed maneuverability. The combination of high-speed and long-distance advantages will play a greater role in the field of military and civil aviation

Embodiment 1

[0049] Such as Figure 1-3 , a high-speed long-endurance aircraft, comprising a fuselage 1, wings 2, lift rotor 3, vertical tail 4, horizontal tail 5, propeller 6, rotating rotor system and power system; wherein, the power system is propeller 6, Rotating rotor system and lift rotor 3 provide power. An electronic governor 2 is arranged on the transmission path between the power system and the lift rotor 3 .

[0050] The wing 2 adopts a wing with a large aspect ratio, and is symmetrically arranged on both sides of the fuselage 1; the lift rotor 3 is located above the head of the fuselage 1, and the lift rotor 3 is a coaxial dual rotor, and the upper and lower rotors of the coaxial dual rotor Same speed, opposite direction. Wherein, there are two propulsion paddles 6, which are respectively arranged on the trailing edge of the wing 2, and the propulsion paddles 6 are arranged symmetrically with respect to the fuselage 1; wherein the two propulsion paddles 6 rotate at the same s...

Embodiment 2

[0056] Such as Figure 1-3 , when the aircraft among the present invention is the vertical lift mode: the working principle and the flight method of the aircraft among the present invention are: start the engine of the aircraft among the present invention, and the engine transmits power to the lift rotor 3 by the lift transmission system; The system transmits power to the rotating rotor 11 . Increase the output power of engine now, utilize electronic governor two to control the rotating speed of lift rotor 3; Utilize electronic governor three, control the rotating speed of rotating rotor 11; Make the rotating speed of lifting rotor 3 and rotating rotor 11 increase, further make total When the pulling force increases, when the total pulling force is enough to overcome the weight of the whole machine, the aircraft will rise vertically from the ground; on the contrary, if the output power of the engine is reduced, the aircraft will descend vertically until the aircraft lands in b...

Embodiment 3

[0058] Such as Figure 1-3 , when the aircraft among the present invention was converted into the high-speed level flight mode by the vertical lifting mode, its conversion principle and method were: start the engine of the aircraft among the present invention, and the engine transmits power to the lift rotor 3 through the lift transmission system; The transmission system transmits power to the rotating rotor 11 . Increase the output power of engine now, utilize electronic governor two to control the rotating speed of lift rotor 3; Utilize electronic governor three, control the rotating speed of rotating rotor 11; Make the rotating speed of lifting rotor 3 and rotating rotor 11 increase, further make total The pulling force increases, and when the total pulling force is enough to overcome the weight of the whole machine, the aircraft will rise vertically from the ground. After the aircraft reaches a certain height, start the power supply system, and the battery drives the prop...

Abstract

The invention discloses a high-speed long-endurance aircraft, which comprises a fuselage, a wing, a lifting rotor, a vertical tail, a horizontal tail, a propulsion paddle, a rotating rotor system anda power system; the power system provides power for the propulsion rotor, rotating rotor system and lifting rotor. The wings are symmetrically arranged on both sides of the fuselage; a lifting rotor is positioned above that fuselage head; two or more propulsion paddles are arranged on the trailing edge of the wing, and symmetrically arranged with respect to the fuselage. The vertical tail and thehorizontal tail are arranged at the tail of the fuselage, and the vertical tail is perpendicular to the horizontal tail. There are two horizontal tail fins, symmetrically arranged on both sides of thevertical tail fins. The aircraft provided by the invention integrates the characteristics of the vertical take-off and landing aircraft and the advantages of the long endurance aircraft, has simple control system, and realizes the horizontal taxiing function of the long endurance manned aircraft.

Description

technical field [0001] The invention relates to the technical field of flight, and more specifically relates to a high-speed and long-endurance aircraft. Background technique [0002] High-speed rotorcraft is an aircraft that combines the characteristics of vertical take-off and landing of rotorcraft and the characteristics of high-speed and long-distance fixed-wing. It plays an irreplaceable important role and has a very broad application prospect. [0003] Since the invention of rotorcraft such as helicopters, it has played a huge role in the field of military and civil aviation. Because the rotor is used to provide lift, it has excellent hovering and low-speed performance, which is its advantage compared with fixed-wing aircraft. Providing lift and overcoming forward flight resistance also limits the improvement of its flight speed. It is difficult to achieve the higher speed and longer range that fixed-wing aircraft can achieve, which is not conducive to expanding its a...
