Abstract
The utility model discloses a start -up power generation facility of turbojet engine, including fixing the pivot in motor case by the pivoted, the one end of pivot be provided with the impeller, the other end is provided with the turbine, is close to the one end of impeller is provided with the diffuser, the pivot on, be provided with power generation facility between impeller and the diffuser, power generation facility include brushless permanent magnetism direct current motor, put power generation facility's mounted position between compressor impeller and diffuser, moreover the starter motor changes brushless permanent magnetism direct current motor into for the whole contraction in length of engine, and the motor no longer blocks the entering of air uses miniature whirlpool to spout engine bearing and saves the motor and hold from the tape spool, makes turbojet engine combustion efficiency increase, improve the thrust -weight ratio, reduce the space and occuping. Power generation facility double as starter motor and generator, the power generation facility after the start -up has the motor to become the generator, makes the one of which machine dual -purpose.
Description
Technical field
This utility model relates to turbojet engine technical field, and the startup particularly to a kind of turbojet engine is sent out
Electric installation.
Background technology
Existing turbojet engine starts motor and mainly uses special brush motor, and volume is big, generally pacifies
It is loaded on before turbojet engine the suction hindering air, also add the length of turbojet engine, have impact on whirlpool
Wheel efficiency of combustion, and start motor Heavy Weight, starting current is big, it is big to require power supply capacity, adds whirlpool
The weight of fuel-injection engine thus reduce the performance of turbojet engine.And this startup motor is only in start-up course
Middle use, after engine start, actuating motor the most no longer works, owing to its effect single wastes resource.
Utility model content
It is many that the technical problems to be solved in the utility model is to provide a kind of startup electric motors function, enhances product performance
The startup TRT of turbojet engine.
In order to solve above-mentioned technical problem, the technical solution of the utility model is: opening of a kind of turbojet engine
Dynamic TRT, including the rotating shaft being fixed in engine shell body that can rotate, one end of described rotating shaft
Being provided with impeller, the other end is provided with turbine, and one end of described impeller is provided with diffuser, described
In rotating shaft, being provided with TRT between impeller and diffuser, described TRT includes that brush-less permanent magnetic is straight
Stream motor.
Preferably, described brushless permanent magnet DC motor includes rotor and stator.
Preferably, described rotor includes that DC rotor, described stator include DC stator.
Preferably, described rotating shaft is fixed in engine shell body by bearing chamber, described bearing chamber two ends
By bearing fixed rotating shaft.
Preferably, described rotor is fixed in described rotating shaft, and described stator is fixed on described bearing
On room or motor body or diffuser.
Preferably, described diffuser is fixed on described bearing chamber.
What employing technique scheme this utility model reached has the beneficial effect that the installation site of TRT
It is placed between compressor impeller and diffuser, and described startup motor changes brushless permanent magnet DC motor into, makes
The entire length obtaining electromotor shortens, and motor no longer stops the entrance of air, uses Micro Turbine Jet Engine
Bearing saves motor and carries bearing, makes turbojet engine efficiency of combustion increase, improve thrust-weight ratio, decrease
Space hold.TRT doubles as starting motor and electromotor, and the TRT after startup has motor to become
Electromotor so that it is dual-use, the deficiency of the waste resource that the most no longer works after electric motor starting before solving,
And its generated energy increases.

In figure: 1. impeller, 2. rotor, 3. stator, 4. diffuser, 5. rotating shaft, 6. bearing chamber, 7. turbine.
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described further.Explanation is needed at this
, the explanation of these embodiments is adapted to assist in and understands this utility model, but be not intended that this reality
With novel restriction.Additionally, technology involved in each embodiment of this utility model disclosed below
Just can be mutually combined as long as feature does not constitutes conflict each other.
In conjunction with accompanying drawing 1, this utility model is further described, make person of ordinary skill in the field more preferable
Implementing this utility model, the startup TRT of this utility model turbojet engine, including consolidating of can rotating
The rotating shaft 5 being scheduled in engine shell body, one end of described rotating shaft 5 is provided with impeller 1, and the other end is provided with
Turbine 7, is provided with diffuser 4 near one end of described impeller 1, it is characterised in that: in described rotating shaft 5,
Being provided with TRT between impeller 1 and diffuser 4, described TRT includes brushless permanent-magnet direct-current electricity
Machine, described brushless permanent magnet DC motor includes rotor 2 and stator 3；Described rotor 2 includes DC
Rotor 2, described stator 3 includes DC stator 3.
Rotating shaft 5 described in the utility model is fixed in engine shell body by bearing chamber 6, described diffusion
Device 4 is fixed on described bearing chamber 6；Bearing fixed rotating shaft 5 is passed through at described bearing chamber 6 two ends；Described
Rotor 2 be fixed in described rotating shaft 5, described stator 3 is fixed on described bearing chamber 6 or starts
On casing body or diffuser 4.
This utility model is placed on the installation site of TRT between compressor impeller 1 and diffuser 4, and
And described startup motor changes brushless permanent magnet DC motor into so that the entire length of electromotor shortens, and motor
No longer stop the entrance of air, use Micro Turbine Jet Engine bearing to save motor and carry bearing, make whirlpool erupt
Motivation efficiency of combustion increases, improves thrust-weight ratio, decreases space hold.TRT doubles as starting motor
And electromotor, the TRT after startup has motor to become electromotor so that it is dual-use, solves
The deficiency of the waste resource that the most no longer worked after electric motor starting in the past, and its generated energy increases.
Above in association with accompanying drawing, embodiment of the present utility model is explained in detail, but this utility model does not limits
In described embodiment.For a person skilled in the art, without departing from this utility model principle
In the case of spirit, these embodiments are carried out multiple change, revises, replace and modification, still fall within
In protection domain of the present utility model.
