Description
Technical field
The present invention relates to aeroengine combustor buring room diffuser testpieces field, a kind of more particularly to disconnectable rectangle
Diffuser.
Background technology
The effect of diffuser is that the angled speed of band at blower outlet is larger in aeroengine combustor buring room
Air-flow carries out rectification and reduction of speed is pressurized to reach the condition of suitable burner inner liner burning.The size of diffuser static pressure recovery coefficient, always
The size that crushing loses directly affects the performance of combustion chamber entirety, it is therefore desirable to carries out in-depth study to diffuser.Traditional expansion
Depressor testpieces, which is required for doing substantial amounts of testpieces, to be compared, and wastes substantial amounts of resource.
The content of the invention
The purpose of the invention is to individually be split as needed, the use of other parts is not influenced, is provided
A kind of disconnectable rectangle diffuser.
The present invention provides a kind of disconnectable rectangle diffuser, it is characterised in that：The disconnectable rectangle diffusion
Device, including import turbulator 1, import installation side 2, preposition diffuser 3, sudden expansion section 4, casing 5, calotte 6 and rear bleed section
7；
Specially：Import turbulator 1 is connected with preposition diffuser 3；Preposition diffuser 3 is installed side 2 by import and is consolidated
Calmly, together with installation side 2 is bolted with sudden expansion section 4；Sudden expansion section 4 is connected with casing 5, and internal calotte 6 is complete
Containing, rear bleed section 7 is connected with calotte 6.
The import turbulator 1, before preposition diffuser 3, is fixed on by screw and preposition diffuser 3
Together.
The preposition diffuser 3, leading portion ensure air-flow smooth transition for horizontal rectification section, and back segment is preposition diffuser
Runner type face.Preposition diffuser is divided into upper and lower two parts, is respectively bolted on import turbulator 1, and centre is logical
Cross to be fitted close with installation side 2 and play the role of supporting mutually.
The sudden expansion section 4, when front-end and back-end are machined with the installation being easy to and install in 2 and the connection of casing 5 respectively, in
Section is the sudden expansion section of diffuser, and the sudden expansion angle with different angle is in order to the comparison and research during testing.
The casing 5, front-end and back-end are machined with installation side respectively.
Calotte 6, arranged on left and right sides are rectangular steel plates, and center section is the steel plate of simulation flame tube head calotte shape, steel plate
Both sides up and down be machined with installation support plate, calotte 6 and bleed section are linked together with will pass through bolt.Center section and left and right
The steel plate of both sides is integrally welded, prevents both sides gas leakage.Equally, can be had herein according to the size or length processing of calotte mouth
Different schemes, is individually replaced, and does not influence miscellaneous part.
Bleed section 7, front end are the installation side and covering plate structure that calotte 6 and casing 5 link into an integrated entity, and are bonded with calotte 6
The face at place is equipped with groove, can fix calotte 6 on the cover board, and installation bolt is tightened.With upper and lower two pieces of calotte for border
Cover board is divided into 3 regions many apertures are had in these three regions, it is small so that 7 back segment of bleed section draws air
Hole can also carry out part closure to achieve the purpose that to compare according to the needs of bleed ratio.
Advantages of the present invention：
Disconnectable rectangle diffuser of the present invention, inducer, sudden expansion section and endpiece can be replaced individually,
Entirety installation and the normal work of other parts have not been influenced, certain form of diffuser can have been goed deep into by this part
Research, obtain closing pitot loss, the parameters such as static pressure recovers, while it has the advantages of simple in structure, reliability is high concurrently.
