Description
Technical field
The utility model is related to hydrodynamics technology field, more particularly to a kind of hypersonic inlet self-starting ability inspection
Survey device.
Background technology
Using supersonic combustion (super burn) punching engine as the Air-breathing hypersonic vehicle of power set, for obtain compared with
Good performance, it is desirable to capture, the hypersonic inlet of compression member has good self-starting ability, that is, work as its air-flow
Cause after the inoperative factor elimination of air intake duct, it is not necessary to which extra auxiliary starter measure, air intake duct can also revert to starting
State (is restarted).However, free stream Mach number is too low, the angle of attack is excessive, the excessively high flight of air intake duct back-pressure and Manipulative Factors, all may be used
Air intake duct can be caused inoperative, have a strong impact on flight safety.The inoperative risk of air intake duct is met with flight test in order to reduce,
The self-starting ability of hypersonic inlet is detected in the wind tunnel experiment of ground, skill is tested as an important wind tunnel experiment
Art.
In view of hypersonic wind tunnel continuous difficulty for controllably changing free stream Mach number in a blowing experiment, generally exists
Under conditions of fixed free stream Mach number, air intake duct self-starting ability test experience is carried out.During the experiment of conventional hypersonic wind tunnel
Between it is longer, up to the second to tens of second-times, by actuation mechanisms such as traditional stepper motor, magnetic valves, carry out air intake duct from
Kinetic force test experience is relatively easy.There is scholar in conventional hypersonic wind tunnel, by the lip cover of mobile air intake duct, continuously change
Become the angle of attack of air intake duct, the choke plug of mobile air intake duct downstream simulation air intake duct back-pressure to bore, in air intake duct downstream injection high pressure gas
The measures such as body segment stream, first force air intake duct inoperative, then remove the inoperative factor of corresponding air intake duct, and air intake duct is recurred
Act to assert that air intake duct has the foundation of self-starting ability under similar conditions.
Ground impulse type wing tunnel test apparatus by representative of shock tunnel, it is relatively low with its construction and operating cost,
The method of operation flexibly, can provide the advantage of high-enthalpy flow for large scale air intake duct, in hypersonic aircraft research field hair
Wave important effect.However, the experimental period of shock tunnel is of short duration, generally only millisecond is conventional superb to several ms magnitude
Air intake duct self-starting ability detection technique in velocity of sound wind-tunnel, it is impossible to which direct " transplanting " is applied to shock tunnel.Therefore, shock wave wind
Hole faces the challenge of air intake duct self-starting ability test experience method.
In the prior art, some scholars force air inlet to be said by setting quick sliding valve at inlet throat
It is existing inoperative, and detect in shock tunnel the self-starting ability of air intake duct.However, this quick sliding valve, not only its skill
Art difficulty is big, and also needs to specially be designed for specific air intake duct configuration, and its versatility is limited.Also scholar passes through
Distance piece lower wall surface in air intake duct downstream is pre-placed lightweight tamper, first forces air intake duct inoperative, thing to be occluded occur
It is blown runner after air intake duct and recovers unimpeded, then detects the self-starting ability of air intake duct.Although this detection method is easy,
It is that the geometry of lightweight tamper is irregular, and the modes of emplacement of tamper is more random, and the movement law of tamper is indefinite,
The forms of motion of tamper can not be controlled effectively, and tamper is reused after cannot also reclaiming.These factors, result in blocking
Thing action effect it is repeatable poor.In addition, some scholars close air intake port using installation polyester fiber diaphragm in advance,
First force air intake duct inoperative;Then, polyester fiber diaphragm is ruptured using pulse high-energy igniter in experimentation, opens air inlet
Road is exported, and detects the self-starting ability of air intake duct.However, experiment needs to reinstall polyester fiber diaphragm this test device every time,
And certain puzzlement is brought to control mode and security using pulse high-energy igniter.Therefore, using shock tunnel as generation
In the impulse type wind-tunnel of table, the experimental method of hypersonic inlet self-starting ability detection needs further improve.
