3, folding and expanding mechanism is unable to get effective verifying on launching cradle, and verifying subject is limited.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of for the cold air emitter of flight test and flight
The cold air launching technique of device, to simulate true emission state, compared to traditional launching cradle, the project of the utility model verifying is more filled
Point, it is as a result more accurate, reliable.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is as follows:
A kind of cold air emitter for flight test, including power gas source, the first valve, gas storage being sequentially communicated
Tank, launching tube, the launching tube are installed on bracket, and the height of launching tube transmitting terminal is higher than the height of launching tube inlet end, institute
It states and solenoid valve is installed on launching tube；The air accumulator is equipped with third pressure gauge.
The power gas source is high pressure nitrogen air accumulator.
Pass through pipeline connection between first valve and air accumulator, is successively arranged first pressure gauge on the pipeline, subtracts
Pressure valve and second pressure gauge.In this way, power gas source mesohigh gas enters the positions such as air accumulator after pressurizing valve pressure regulation.
Second valve is installed, the second valve can be used as safety valve, let out reservoir pressure is excessively high on the air accumulator
Pressure.
The air accumulator is connected to one end of launching tube by high-pressure hose.
The bracket is equipped at least two mounting bases, and the launching tube is fixed on branch by least two mounting base
On frame, guarantee launching tube mounting stability.
In some embodiments of the utility model, the high pressure gas discharged from high pressure nitrogen air accumulator is by pressure reducing valve tune
After pressure enter gas delivery tube road, after pipeline inner pressure reaches setting value, the first valve close, pressure maintaining for a period of time, electromagnetism
Valve is opened, and in gas transport pipeline under the promotion of high pressure gas, is launched object and is travelled forward；Gas enters in launching tube, quilt
Emitting substance moves forward under the action of high pressure gas in launching tube, goes out launching tube until being launched object.
The cold air launching technique of aircraft is carried out using cold air emitter as described above, is included the following steps:
S1, aircraft to be launched is packed into launching tube；
S2, it keeps solenoid valve to close, opens the first valve, so that the power gas in power gas source enters in air accumulator,
After gas storage pressure inside the tank reaches setting value, the first valve, pressure maintaining 1min are closed；
S3, solenoid valve is opened, completes the transmitting of aircraft.
Compared with prior art, the cold air emitter emission process ratio of the utility model more actually simulates aircraft
Actual transmission state, compared to traditional launching cradle, the project of verifying is more abundant, as a result more accurate, reliable, has wide
Application prospect.
Detailed description of the invention
