Abstract

The invention discloses a helicopter design using a centrifugal rotor engine. The helicopter using the centrifugal rotor engine directly drives a main rotor wing of the helicopter or drives the main rotor wing of the helicopter after decelerating through a reducer, thereby avoiding the known problems of driving the main rotor wing of the helicopter by wing tip jetting, i.e. the phenomenon that a wing tip jet engine inhales tail gas generated by itself to shut down or cause power descent. The centrifugal rotor engine drives a spindle to rotate and drives a back propulsion propeller to rotate after steering through a steering gear, thereby enhancing the propulsion efficiency of the helicopter, also realizing the functions of a rotorcraft and ensuring that the engine of the helicopter has the advantages of stable work and simple structure.

Description

Use the helicopter of centrifugal rotor engine

Technical field

The present invention relates to the jet-driven helicopter of wing tip, especially be different from known use ramjet propulsion or pulse duct as the jet-driven helicopter of wing tip.

Background technology

At present, the jet-driven helicopter of known blade tip uses ramjet propulsion or pulse duct as the blade tip jet drive; But the admission port of driving engine and burning gases air nozzle are in the circumference of a horizontal surface; Driving engine sucks the tail gas of self easily and causes and shut down or power decline.

Summary of the invention

In order to solve existing use ramjet propulsion or pulse duct cause shutdown or power decline because of the waste gas of suction oneself generation easily as the jet-driven helicopter engine of wing tip problem.The invention provides and use me to propose the helicopter of the centrifugal rotor engine (200910148645.9) of patent application as driving engine, the present invention solves the scheme that its technical matters adopts: use centrifugal rotor engine to drive main rotor, perhaps use centrifugal rotor engine to drive main rotor again, to produce raising force through after the speed change; Deflector and change-speed box can be with the takeoff output of centrifugal rotor engine to cardan shafts, and drive the propelling screws rotation, for helicopter provides thrust.

The beneficial effect that the present invention carries is: solved the jet-driven helicopter engine of existing wing tip because the easy problem that sucks the tail gas of self and cause shutdown or power to descend; the dynamic structure of helicopter is simplified; improved the work efficiency and the stability of helicopter, driven propelling screws and improved propulsion coefficient.

The specific embodiment

In Fig. 1 to Fig. 6,1. centrifugal rotor engine, 2. main shaft, 3. speed change and deflector, 4. main rotor sleeve, 5. main rotor, 6. cardan shaft, 7. propelling screws, the 8. downward jet engine of centrifugal rotor, the 9. downward jet engine spout of centrifugal rotor.

In Fig. 1, centrifugal rotor engine (1) is fixedly linked with main shaft (2).

In Fig. 2, main shaft (2) drives main rotor (5) rotation, and main rotor (5) produces lift; Speed change and deflector (3) can be as required with the takeoff output of main shaft (2) to cardan shaft (6); Cardan shaft (6) drives propelling screws (7) rotation and produces thrust.

In Fig. 3, centrifugal rotor engine (1) drives main shaft (2) rotation, and the power of main shaft (2) is input to speed change and deflector (3), outputs to main rotor sleeve (4) through after the speed change; Main rotor sleeve (4) is captiveed joint with main rotor (5), makes main rotor (5) rotation, produces lift.Speed change and deflector (3) can be as required with the takeoff output of main shaft (2) to cardan shaft (6); Cardan shaft (6) drives propelling screws (7) rotation and produces thrust; After helicopter reached certain speed, centrifugal rotor engine (1) did not drive main rotor (5) rotation, and only drive propelling screws (7) rotation and produce thrust, main rotor (5) spinning down with the wind, this moment, helicopter was in the cyclogyro state of flight.

In Fig. 4, the downward jet engine of centrifugal rotor (8) is center of circle rotation with main shaft (2), and the jet gas of the downward jet engine spout of centrifugal rotor (9) produces and goes up thrust and forward thrust.

In Fig. 5, when taking off, the downward jet engine of centrifugal rotor (8) rotation, the jet gas of the downward jet engine spout of centrifugal rotor (9) produces and goes up thrust and forward thrust, makes helicopter rising, the downward jet engine of centrifugal rotor (8) rotation; Main shaft (2) is not input to power speed change and deflector (3).When flying forward, main shaft (2) also is input to speed change and deflector (3) with power, drives propelling screws (7) rotation and produces thrust.

In Fig. 6, centrifugal rotor engine (1) drives main shaft (2) rotation, and main shaft (2) direct drive and main rotor (5) rotation produce lift.Speed change and deflector (3) can be as required with the takeoff output of main shaft (2) to cardan shaft (6); Cardan shaft (6) drives propelling screws (7) rotation and produces thrust.
