Abstract
The utility model belongs to field of turbochargers, specifically a kind of guide ring with two-sided centrifugal pinch roller miniature turbine jet engines.It comprises outer shroud and inner ring, is fixed with some radial guide pillars, is provided with pod apertures in radial guide pillar between outer shroud and inner ring, and interior ring outer surface is taper, and tapering is α is 4-6 °.The utility model has the advantages that the air inlet problem solving the two-sided centrifugal compressor lobus dexter wheel of Micro Turbine Jet Engine well, the inlet loss that it makes lobus dexter take turns is less, simultaneously, meet again the demand to air mass flow, its compact structure, rationally, lightweight, guide ring and motor matching coordinative, do not increase the wind-exposuring area of motor.
Description
Technical field
The utility model belongs to field of turbochargers, specifically a kind of guide ring with two-sided centrifugal pinch roller miniature turbine jet engines.
Background technique
Microvovtex is a kind of aviation power that turbojet engine develops rapidly in recent years.Its feature is the macro of traditional turbojet engine power and geometric scale, the simplification of structure.It has a wide range of applications in a lot of fields, and its working principle is same as conventional turbine air breathing engine.This project guide ring is then the vitals of miniature turbine jet engines, and its function is that the high pressure draught that two-sided centrifugal compressor three-dimensional diffuser flows out is imported firing chamber after rectification, deceleration, diffusion.And ambient air is introduced the right impeller inlet of two-sided gas compressor by the radial guiding discharge orifice on guide ring.It is a kind of structural member, and adopt welding or precision casting to form, material is generally aluminum alloy or cast aluminium.
Summary of the invention
The utility model provides a kind of guide ring being applied in miniature turbine jet and starting, and the high pressure draught that two-sided centrifugal compressor three-dimensional diffuser flows out can be imported firing chamber by it after rectification, deceleration, diffusion.
Have employed following technological scheme:
Have the guide ring of two-sided centrifugal pinch roller miniature turbine jet engines, it comprises outer shroud and inner ring, is fixed with some radial guide pillars, is provided with pod apertures in radial guide pillar between outer shroud and inner ring, and interior ring outer surface is taper, and tapering is α is 4-6 °.
Described outer ring inner surface and the outer surface of inner ring are all evenly equipped with the fixed hole of eight directional posts.
Described radial guide pillar is provided with eight, is equipped with pod apertures in radial guide pillar.
The utility model has the advantages that the high pressure draught that two-sided centrifugal compressor three-dimensional diffuser flows out can be imported firing chamber by it after rectification, deceleration, diffusion, solve the air inlet problem of the two-sided centrifugal compressor lobus dexter wheel of Micro Turbine Jet Engine well, the inlet loss that it makes lobus dexter take turns is less, simultaneously, meet again the demand to air mass flow, its compact structure, rationally, lightweight, guide ring and motor matching coordinative, do not increase the wind-exposuring area of motor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the right elevation of Fig. 1;
Fig. 3 is application schematic diagram of the present utility model.
Embodiment
As shown in Figure 1 and Figure 2, there is the guide ring of two-sided centrifugal pinch roller miniature turbine jet engines, it comprises outer shroud a and inner ring b, be fixed with some radial guide pillar c between outer shroud a and inner ring b, be provided with pod apertures d in radial guide pillar c, inner ring a outer surface is taper, tapering is α is 4-6 °, the outer surface of outer shroud a internal surface and inner ring b is all evenly equipped with the fixed hole e of eight directional posts, and radial guide pillar d is provided with eight, is equipped with pod apertures d in radial guide pillar d.
As shown in Figure 3, two-sided centrifugal pinch roller miniature turbine jet engines comprises starting electrical machinery 1, two-sided centrifugal compressor 2, three dimensional streamline Diffuser 3, middle casing 4, nozzle ring 5, turbine 6, exhaust tail cone 7, jet pipe 8, outer casing 9, firing chamber 10, guide ring 11, rotor shaft 12, air inlet rectifier 13, aiding support 14, left main supporting 15 and right main supporting 16, ambient air is by miniature turbine jet engines suction port f, pod apertures d enters two-sided centrifugal compressor 2, become high-pressure air after being compressed and flow into three dimensional streamline Diffuser 3, firing chamber 10 is entered again after guide ring 11 diffusion slows down.
Guide ring should have less flow resistance in using; Produce at each operating conditions non-obstruction phenomenon of motor; Structure is reliable, has good rigidity, and the utility model adopts welding or precision casting to form usually, and material is generally aluminum alloy or cast aluminium.
