Abstract
The utility model belongs to the auxiliary power system technology relates to an eccentric blast pipe that local gas -bearing rotor power device used, an eccentric blast pipe that local gas -bearing rotor power device used, and it includes: eccentric gas vent (1), baffle (2) and flange (3), characterized by, the central point that blast pipe is deviated in eccentric gas vent (1) puts, just to local gas -bearing rotor's work blade, using the exhaust orientation to lie in the upper reaches of eccentric gas vent (1) as positive direction, baffle (2), covering other inoperative blades, eccentric blast pipe passes through flange limit (3) and is connected with the volute end. The utility model discloses the local gas -bearing rotor power device gas vent size of creating of beneficial effect reducible to enough reduce the exhaust loss.
Description
Technical field
This utility model belongs to accessory power system technology, it is possible to for aircraft emergency power plant。
Background technology
Development along with aircraft the second dynamical system synthesization, it is desirable to work turbine can work under multiple inlet air conditions, and partial admission's turbine is the effective way realizing multi-mode working。The discharge characteristic of partial admission's turbine is different from conventional full admission turbine, and air-flow accumulates near working-blade, and traditional in line structure is unfavorable for the abundant development of air-flow, thus adding discharge loss。
Summary of the invention
The purpose of the present invention: the invention provides a simple in construction, is suitable for the eccentric exhaust pipe structure of partial admission's turbine power plant。
Technical scheme: the eccentric exhaustor of a kind of partial admission turbine power plant, comprising: eccentric air vent 1, baffle plate 2 and flange 3, eccentric air vent 1 deviates the center of exhaustor, is right against the working-blade of partial admission's turbine；With discharge directions for positive direction, baffle plate 2 is positioned at the upstream of eccentric air vent 1, covers other inoperative blades, and eccentric exhaustor is connected with volute end by flange 3。
Preferably, the aperture area of eccentric air vent 1 is less than exhaustor。
The beneficial effect of the invention
Partial admission's turbine power plant air vent size can be reduced, and enough drop discharge loss。
Accompanying drawing explanation
Fig. 1 is the gas generator structure chart of this reality invention。
Wherein, 1-bias air vent, 2-baffle plate, 3-flange。
Detailed description of the invention
A kind of eccentric exhaustor sectional view such as Fig. 1 of partial admission turbine power plant。Exhaustor is connected with volute end by flange (3), and air-flow flows into from flange (3), flows out from eccentric air vent (1)。Eccentric air vent (1), not in the center of exhaustor, is right against partial admission's moving turbine blade part, is only capable of so that partial admission's moving turbine blade tail gas is discharged。Baffle plate (2) is positioned at eccentric air vent (1) upstream, covers other inoperative blades, reduces the air-flow flowing at inoperative leaf area。
Claims (2)
1. the eccentric exhaustor of partial admission's turbine power plant, comprising: eccentric air vent (1), baffle plate (2) and flange (3), it is characterized in that, the center of eccentric air vent (1) deviation exhaustor, is right against the working-blade of partial admission's turbine；With discharge directions for positive direction, baffle plate (2) is positioned at the upstream of eccentric air vent (1), covers other inoperative blades, and eccentric exhaustor is connected with volute end by flange (3)。
2. eccentric exhaustor as claimed in claim 1, it is characterised in that: the aperture area of eccentric air vent (1) is less than exhaustor。
