Technical field
The utility model relates to a kind of experimental rigs, and in particular to a kind of pack boronitriding examination of simulated altitude environment
Experiment device.
Background technique
Pack boronitriding passes through the burning of gas generator propellant powder column, generates the combustion gas of certain flow, pressure and temperature；
As a kind of gas supply device, form simple, compact-sized with it and produce the rapid feature of gas, be widely used in it is all kinds of not
Same occasion；Igniter is the important composition component of gas generator, is also relatively easy the component of failure；Igniting dress
The unreasonable design set will lead to excessively high firing delay, ignition Pressure or even therefore cold run, igniting explosion are sent out in combustion gas
In raw device design process, it is necessary to carry out ignition performance certification test for igniter.
For being applied to the gas generator of high altitude environment, ignition performance certification test is relatively more complicated, it is necessary to consider
Influence of the high aerial environment under low pressure to igniting；It therefore, is that high-altitude is low how in the high aerial true point fire environment of ground simulation
The critical issue that pressure fire trial needs to solve；Various types of vacuum chambers have been had both at home and abroad at present, it being capable of simulated altitude
Gas generator can be placed in vacuum chamber and test by environment under low pressure；But using vacuum chamber carry out test exist test it is complicated,
The disadvantage that preparatory period is long, experimentation cost is high, the fire trial for being unsuitable for gas generator especially small gas generator make
With.
Utility model content
The purpose of the utility model is to provide a kind of pack boronitriding experimental rigs of simulated altitude environment, can
The point fire environment of enough simulated altitudes, examines the ignition performance of igniter.
To achieve the above objectives, the present invention adopts the following technical solutions:
A kind of pack boronitriding experimental rig of simulated altitude environment, gas generator experimental rig are fired with solid
Gas generator；System for solid rocket grain is installed in the shell of pack boronitriding；The system for solid rocket grain by tail portion simulation powder column and
The true powder column in head is bonded；The length of the tail portion simulation powder column is greater than the size of the true powder column in head;The tail portion mould
Quasi- powder column is reusable structure；The overall dimensions of the system for solid rocket grain are identical as the size of powder column under true environment；Gu
The combustion gas spout of body fuel gas generator is sealedly connected with the vacuum tank to simulated altitude environment；The corresponding vacuum tank setting
There is coupled logical suction line；One end of the suction line and the vacuum tank are tightly connected, and other end connection is true
Sky pump；Pressure sensor, shut-off valve and exhaust valve are additionally provided in the suction line.
The utility model proposes a kind of simulated altitude environment pack boronitriding experimental rig, using vacuum tank mould
Quasi- upper low environment guarantees that the back pressure during the ignition of gas generator is identical as real operating environments；Relative to vacuum chamber,
The utility model has the characteristics that small in size, structure is simple, sucking rate is small, experimentation cost is low；In addition, being not necessarily in test by combustion gas
Generator is mounted in vacuum chamber, is reduced test complexity, can be obviously shortened test time；In the utility model
In, powder column is simulated by tail portion and the true powder column in head replaces true gas generator propellant powder column, guarantees that the ignition of gas generator is empty
Between and initial combustion face it is constant；Tail portion simulation powder column will not burn as inertia powder column, the combustion that only the true powder column burning in head generates
Tolerance is significantly lower than true gas generator propellant powder column；Gas quantity during test reduces, simple true under identical pressure conditions
The volume of slack tank can reduce, therefore be conducive to the reduction of simple vacuum tank volume using tail portion simulation powder column, can reduce examination
Test cost and time；In addition, tail portion simulation powder column can be reused, experimentation cost can be reduced.
