Description
Technical field
The utility model relates to a kind of microminiature aero-engine, in particular to one kind that a kind of new approaches are founded is novel micro-
Small-sized whirlpool paddle jet engine.
Background technique
The development history of modern age aircraft power plant is made a general survey of, (hereinafter referred to as whirlpool paddle starts aircraft gas whirlpool paddle jet engine
Machine) appearance eventually led to the earth-shaking variation of aircraft performance, there is epoch-making significance, sprayed soon in whirlpool
On the basis of engine technology again be born gas turbine airscrew engine (abbreviation turbo oar engine), combustion gas turbofan starts
Machine (abbreviation fanjet) and combustion gas turboshaft engine (abbreviation turboshaft engine) etc., it is increasingly mature with technology, gradually
Applied in each department of aviation field, such as the large aerospace engine of high thrust, it is widely used in airliner and military now
On transporter.
The working principle and characteristic of turbojet, aviation piston engine and turbo oar engine is compared as follows:
1) turbojet is a kind of direct reaction propulsion device, when velocity air is pressurized after air intake duct,
Fuel oil, which enters, to be sprayed with the high high temperature gas flow of speed after combustion chambers burn expansion and directly generates reaction thrust, and a part of air-flow is outside
It scatters and disappears, causes working efficiency lower.
2) piston aviation engine is the petrol engine of 4 strokes of one kind, sparking plug igniting.By piston in vapour when work
4 times (i.e. 4 strokes) are moved back and forth in cylinder.4 strokes are followed successively by air-breathing, compression, expansion and exhaust, collectively form 1 and determine
Hold heat cycles.Piston aviation engine technology maturation, oil consumption rate is low, and disadvantage is that power to weight ratio is small, and ceiling is low.
3) turbo oar engine is derived by turbojet engine, and in whirlpool, the rear of jet engine is further added by N grades of whirlpool paddles, is led to
It crosses turbine transmission combination and drives a certain number of major diameter propellers, constitute turboprop.When whirlpool paddle jet is sent out
When motivation works, sucking air enters combustion chamber, and fuel oil is made to burn in a combustion chamber, forms high speed, high-temperature gas drives power
Turbine drives propeller rotational by retarder, and driving air flows to generate thrust backward.Turbo oar engine passes through increase
Stage of turbine, make full use of the dump energy of outlet gas, improve efficiency, reduce oil consumption.
Microminiature Aeroengine Products application field is extensive, demand is big, dog-eat-dog.Microminiature aero-engine is
Integrate the high-tech dynamical system of modern microelectronic technology, control technology, material technology, manufacturing technology.With traditional whirlpool
Spray, fanjet are compared, and turbo oar engine has many advantages, such as that thrust is big, oil consumption rate is low, cruise-ability is good, with piston engine phase
Have that thrust ratio is high than, turbo oar engine, good reliability, it is altitude good the advantages that.Therefore small-sized turbo oar engine is widely used in gently
Type aircraft, military unmanned air vehicle etc., such as U.S. army " MQ-9 " harvester " unmanned plane and researching and developing " the hollow long endurance in Europe nobody
The power device of machine system " (MALE) has selected turbo oar engine.
But it is small in size, light-weight due to microminiature whirlpool paddle jet engine, microminiature whirlpool is researched and developed with traditional thinking
Technical difficulty required for paddle jet engine is very big, and cost will also be significantly increased therewith, needs to seek in summary a kind of novel
Design concept and technological means research and develop small-sized whirlpool paddle jet engine.
Summary of the invention

1. being that need to seek one kind novel design concept and technological means to research and develop small-sized turbo oar engine；
2. utilizing the novel design concept and technology hand Research idea sought.It is simple to found a kind of structure, low oil consumption, at
This is low, safeguards a kind of easy novel microminiature turbo oar engine.
Realizing the technical solution of the utility model aim is: with existing mature technology, selecting that a kind of structure is simple, performance
Well, the jet engine of microminiature turbine that environmental suitability is strong, maintainability is good is as microminaturization whirlpool paddle jet engine
Core engine and functional unit carry out local structural modification, interface improvement is assembled.It is characterized by: it is the whirlpool by restructuring
Jet engine is taken turns as core engine instead of the gas generator component in the paddle jet engine of whirlpool；It is by gas generator
Component 1, power turbine and gas deflation assembly 2, reducer assemblies 3, propeller 4 form；Reducer assemblies 3 pass through power turbine and row
Pneumatic module 2 and gas generator component 1) it connect, the output shaft of 3 other end of reducer assemblies installs propeller 4.
