Summary of the invention
In view of this; The main purpose of the utility model is to provide a kind of miniature turbine jet engines start-up system; The motor of this turbojet engine is started voluntarily; Replace compressed-air actuated mode of operation, eliminate the restriction of existing technology, to adapt to the characteristics of field work to the engine start number of times.
For achieving the above object, the technological scheme of the utility model is achieved in that
A kind of miniature turbine jet engines start-up system mainly comprises starting electrical machinery 2, starts clutch 5, starting electrical machinery installation sleeve 1 and airscoop shroud 6; Wherein: said starting electrical machinery 2 and starting electrical machinery axle 3 are encapsulated in the starting electrical machinery installation sleeve 1; Said startup clutch 5 is installed on the starting electrical machinery axle 3; Starting electrical machinery installation sleeve 1 is fixed on the airscoop shroud 6; Airscoop shroud 6 is fixed on the inlet casing 9 of motor through six equally distributed fixing bolts 8.
Wherein: the power line 12 of this starting electrical machinery 2 links to each other with the circuit board 11 of engine charge casing 9.
Said circuit board 11 links to each other with control system ECU through datawire.
Inner in the rear end of starting electrical machinery installation sleeve 1, starting electrical machinery axle 3 through spring 13, get rid of piece 14 with pin 15 with get rid of piece cover 16 and link to each other.
The said the other end that gets rid of piece cover 16 is provided with friction pad 17.
The miniature turbine jet engines start-up system that the utility model provided has the following advantages:
Use this start-up system, in the time of can realizing that the small sized turbine air breathing engine is worked in the open air, need not carry a large amount of pressurized air, and can pass through control system (ECU) and start voluntarily; Eliminated restriction, and motor can not produce high temperature when starting, and has effectively increased the life-span of motor, and also can play automatic cooling action later at engine cut-off to the engine start number of times.

Embodiment
Embodiment below in conjunction with accompanying drawing and the utility model does further detailed explanation to this novel start-up system.
Fig. 1 is the horizontal section schematic representation of the utility model miniature turbine jet engines start-up system, and is as shown in Figure 1, and this start-up system mainly is made up of starting electrical machinery 2, startup clutch 5, starting electrical machinery installation sleeve 1 and airscoop shroud 6; Wherein: start clutch 5 and be installed on the starting electrical machinery axle 3; Starting electrical machinery installation sleeve 1 is fixed on the airscoop shroud 6; Airscoop shroud is fixed on the inlet casing 9 of motor through six equally distributed fixing bolts 8.
Adopt motor to start automatically to turbojet engine, have start simple, stable performance, reliability high, be easy to characteristics such as control.
The control of starting electrical machinery is to be connected on the circuit board 11 that is installed in engine charge casing 9 by its power line 12, and circuit board 11 links to each other with control system (ECU) through a data lines.
During engine start; Send actuating signal by control system (ECU) to starting electrical machinery 2; Starting electrical machinery 2 rotates automatically; At this moment be connected on the starting electrical machinery axle 3 startup clutch 5 since the effect of inertia of motor rotation dock with the front end nut (being the set screw nut 7 of centrifugal turbine 10) of motor, thereby the drive engine revolution.The front end that starts clutch 5 is equipped with a silica gel circle, and hemispherical dome structure is adopted on the front end nut top of motor, and annular knurl strengthens the frictional force with the silica gel circle in sphere processing, can prevent that surface of contact skids when starting.
Fig. 2 is the partial exploded view of the utility model miniature turbine jet engines start-up system; As shown in Figure 2; Starting electrical machinery 2 and starting electrical machinery axle 3 are encapsulated in the starting electrical machinery installation sleeve 1; The rear end of said starting electrical machinery installation sleeve 1 is inner, starting electrical machinery axle 3 through spring 13, get rid of piece 14 with pin 15 with get rid of piece cover 16 and link to each other.The said piece that gets rid of overlaps 16 rear portions and is provided with friction pad 17.When starting turbojet engine, this friction pad 17 contacts with the set screw nut 7 of said centrifugal turbine 10.
Introduce the process that the start-up system of utilizing the utility model starts turbojet engine below:
After starting electrical machinery 2 rises to 2500～3500 rev/mins with engine speed, these starting electrical machinery 2 stalls; Firing head energising, initial fuel tap is opened, the oil spout that is interrupted to engine interior; In igniting process, engine speed slowly descends.If once not success of igniting, starting electrical machinery can reattempt several times so.If in 30 seconds, motor is not still lighted a fire successfully, will withdraw from this start-up course, in case light a fire successfully, starting electrical machinery restarts work, drives motor and quickens.When engine speed reached about 3600 rev/mins, oil pump can thoroughly be opened; Engine speed then promotes rapidly, up to reaching stabilized (steady-state) speed.When engine speed surpassed idling, starting electrical machinery stopped operating, and motor promptly starts success.
We are that example (also can customize electric current, voltage, rotating speed and the moment of torsion of direct current generator according to the size of air breathing engine) is tested with the direct current generator of 12V, 10A, 6000rpm.During work, control by control system fully.The miniature turbine jet engines start-up system also can play automatic cooling action later at engine cut-off except the effect with startup, can prevent that engine interior from occurring overheated and the damage parts.
The above is merely the preferred embodiment of the utility model, is not in order to limit the protection domain of the utility model.
