Description
Technical field
Disappear the utility model relates to a kind of propulsive thrust test pressure-air and disturbs device.
Background technique
Engine reverse thrust technology extensive application in current aeronautical technology, thrust reverser, which is one, can make original
Jet-stream wind transfers the device for spraying air-flow forward backward for this.When device starting, engine can change air-flow flow pass, produce
A raw reversed thrust.Aircraft landing is sliding run and take off interrupt sliding run during to reduce its ground run distance, to reduce to race
The limitation of road length, aircraft is frequently with engine reverse thrust technology.Propulsive thrust technology is to civil aviation construction also economy with higher
Value and practical value, runway required for the application of thrust reverser makes aircraft landing is sliding to run greatly are shortened, are landed
Safety greatly improves, the considerable economic benefit created for civil aviation construction.
After the starting of engine reverse thrust device, the high pressure draught sprayed from thrust reverser will be ejected into aircraft machine
On the wing, fuselage, horizontal tail, vertical fin and each control rudder face, the flow field on the rudder face of wing, flat vertical fin and each control is made to send out upper play
Strong variation substantially change aircraft aerodynamic characteristic and control and stability generation.As China's Ci vil Aircraft Design unit tests propulsive thrust
The attention of technology, it is established that mature full mould propulsive thrust wind-tunnel technique has become a top priority.In order to meet aircraft development
In the full mould propulsive thrust wind tunnel test demand of low speed, needs a kind of pressure-air to disappear and disturb device.
Utility model content
Based on the above shortcomings, the utility model, which provides a kind of propulsive thrust test pressure-air and disappears, disturbs device, meets low
The high accuracy testings such as fast full mould intake and exhaust, which disappear to pressure-air, disturbs the demand of device.
Technology used by the utility model is as follows: a kind of propulsive thrust test pressure-air, which disappears, disturbs device, including high-voltage tube
Road, and further include that three flexibilities disappear and disturb unit, the pressure duct is U-shaped structure, is equipped with first in the leading portion of U-shaped structure
Flexibility, which disappears, disturbs unit, disappears in the middle section of U-shaped structure equipped with the second flexibility and disturbs unit, flexible equipped with third in the back segment of U-shaped structure
Disappear and disturbs unit.
The utility model also has following technical characteristic:
1, originally disappearing, to disturb device further include temperature and pressure sensor.
2, the flexibility disappears, and to disturb unit include front end pipeline, back end line, high-pressure seal ring and elastic ring, front end pipeline
It is all enclosed with elastic ring with the outside of back end line, front end pipeline is connect by high-pressure seal ring with back end line.
The utility model have the advantages that disappear immunity can it is good, small in size, at low cost, structure is simple, can also be applied to slide
It flows in turbine motor wind tunnel test.The utility model is able to carry out disappearing for six-freedom degree direction and disturbs, and passes through height in high pressure gas
Pressure air disappear disturb device be turbine device (TPS) gas supply when, can be with the internal pressure of impaired gas, temperature gradient and internal flow to balance
Influence.
Detailed description of the invention
Fig. 1 disappears for the present apparatus disturbs unit external structure；
Fig. 2 disappears for the present apparatus disturbs unit internal structure chart；
Fig. 3 is the combination assumption diagram of the present apparatus and internal balance；
Wherein 1, flexibility disappears and disturbs unit, 2, pressure duct, 3, front end round pipe road, 4, external elastic ring, 5, high pressure sealing
Circle, 6, rear end round pipe road, 7, balance fixed device, 8, internal balance.
Specific embodiment
It illustrates with reference to the accompanying drawings of the specification and the technical solution of the utility model is described further.
Embodiment 1
It as shown in Figure 1, a kind of propulsive thrust test pressure-air, which disappears, disturbs device, including pressure duct, and further include three
