Description
Technical field
The present invention relates to aircraft, specifically a kind of single slurry wing helicopter.
Background technology
Existing light helicopter is mostly the single-blade tailing wing, double-vane, multiple wing helicopter, and mechanical structure is relative complex, price height,
Maintenance cost is high, it is difficult to meet the market demand.
The sustainer of single-rotor helicopter also exports power to the minor spiral paddle of tail portion simultaneously, and the airbone gyro instrument can be detected
Helicopter angle of revolution simultaneously feeds back to tail-rotor, and the difference turn of king bolt paddle generation can be offset by adjusting the screw pitch of minor spiral paddle
Reaction force under speed, at the same time damage can be also bigger, also increases the overall volume of helicopter.Twin-rotor helicopter is usual
The uneven lift of rotor generation is offset, but complicated by the way of the opposite reversion of rotor, flow perturbation is serious, because
There is double-vane, so counterweight increases.
The structure of modern turbojet is made of air intake duct, compressor, combustion chamber, turbine and jet pipe, fight
There is after-burner between the turbine and jet pipe of machine.Turbojet still falls within one kind of heat engine, just must comply with heat
The acting principle of machine：Input energy under high pressure releases energy under low pressure.Therefore, from the principle for generating output energy, spray
Gas formula engine and piston-mode motor are identical, have been required for air inlet, pressurization, burning and have been vented this four-stage, different
, this 4 stages are that timesharing carries out, but be then carried out continuously in jet engine successively in piston-mode motor
, gas just corresponds to four operating positions of piston-mode motor followed by the various pieces of jet engine.
What air initially entered is the air intake duct of engine, when aircraft flight, is considered as air-flow with flying speed stream
To engine, since the speed of aircraft flight is variation, and the speed of incoming flow that compressor adapts to is that have certain range, because
And the function of air intake duct is exactly by adjustable pipe, and incoming is adjusted to suitable speed.In supersonic flight, in air intake duct
Preceding and air intake duct interior air-flow speed reduces to subsonic speed, and the stagnation of air-flow can make even tens times of more than ten times of pressure rise at this time, greatly
The big pressure more than in compressor improves multiple, thus produces and depend merely on speed punching press, and the punching jetting for being not required to compressor starts
Machine.
Compressor after air intake duct is the pressure for being specifically used to improve air-flow, when air flows through compressor, compressor work
Make blade to do work to air-flow, make the pressure of air-flow, temperature raising.In subsonic speed, compressor is the critical piece of air-flow supercharging.
The high-temperature high-pressure fuel gas flowed out from combustion chamber flows through turbine of the same compressor on same axis.The portion of combustion gas
Point interior energy expands in turbine is converted into mechanical energy, drives compressor rotation, in turbojet, gas under equilibrium state
It flows and expands that work done is equal to the work(that is consumed of compressor compressed air and driven accessary is overcome needed for friction in turbine
Work(.After burning, the combustion gas energy before turbine greatly increases, thus the expansion ratio in turbine is much larger than the pressure in compressor
Contracting ratio, the pressure and temperature at turbine outlet is all more much higher than compressor inlet, and the thrust of engine is exactly this Some gases
Energy and come.
The high-temperature high-pressure fuel gas flowed out from turbine continues to expand in jet pipe, with high speed along engine shaft to from spray
Mouth is discharged backward.The speed that this speed enters engine than air-flow is much bigger, and engine is made to obtain counteractive thrust.

Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment shall fall within the protection scope of the present invention.
As shown in attached drawing 1 to Fig. 3, a kind of single slurry wing helicopter, including rack, propeller 1, transmission line shaft 2, power plant
3rd, empennage 4, universal joint assembly 5, the frame upper end universal-joint assembly 5, universal joint assembly upper end connection transmission line shaft 2,
Line shaft upper end connection propeller 1 is driven, total shaft gear, total shaft gear connecting power device 3, the machine are set on transmission line shaft
The rear end connection empennage 4 of frame, the quantity of the power plant at least sets two, under vertical view state all power plants with
It is driven total shaft centre line and forms ring quasi array for the center of circle, the power plant includes the turbojet assembly being connected with each other
10th, change gear assembly 9, the jet direction of the turbojet assembly are opposite with propeller direction of rotation.Use jet
Mouthful power be converted into propeller torque, utilize the rotating speed of gearbox symmetric screw propeller and turbine balance.
According to drawing, the present embodiment employs 2 sets of power plants, it is of course possible to again increased third, the 4th, or more
Turbojet, but to ensure that all power plants under vertical view state form ring to be driven total shaft centre line as the center of circle
Shape matrix.As long as meeting dynamic balancing continues to increase turbine assembly, so as to achieve the purpose that increase power.But 2
It covers to the selection that 4 sets of power plants are comparative superiority.
The turbojet assembly includes turbine, fuel feeding assembly 12, combustion chamber 11, puff prot 13, the fuel feeding
Assembly is between combustion chamber and turbine, the output axis connection change gear assembly of turbine, and change gear assembly reconnects transmission
Total shaft gear on line shaft, combustion chamber external port are puff prot, and the fuel feeding assembly connection is arranged on the fuel tank 6 in rack.Institute
