By single complete independently, this facilitate that the impact test requirement of the structure position of internal body or narrow space.
Further, the position close to end on the gun tube is provided with a pair of of aperture by installing based on photoelectric velocity measurement, this
Distance of the aperture apart from gun tube end is respectively equal to and slightly larger than the length for impacting bullet, passes through this distance divided by punching to aperture
The speed for bouncing off out the time difference of aperture to calculate impact moment impact bullet is hit, the impact bullet speed that this method measures is more accurate.
In addition, the end of gun tube has carried out grid processing, the air before impact bullet is made to be discharged in time from gun tube, it is empty to improve compression
The efficiency of gas.
Further, the convenient operating personnel during experiment of the handle carry the present apparatus and the angle of adjustment impact,
Improve the operability of Portable gas gun device of the present invention.
Concrete scheme is as follows：
For the Portable gas gun device that composite aircraft structure impact injury is prefabricated, including buttstrap 1, air storage chamber 2, hair
Penetrate switch 3, gun tube 4, handle 5, valve-inside type intake valve 6, high-precision electronic air gauge 7 and vent valve 8；One end of air storage chamber 2
It is connected with buttstrap 1；The other end is connected with emission switch 3, and intake valve 6,7 and of high-precision electronic air gauge are equipped on air storage chamber 2
Vent valve 8；The other end of the emission switch 3 is connected with one end of gun tube 4；The other end of the gun tube 4 is opened on air,
On handle 5 is installed, and be provided with by installing the hole based on photoelectric velocity measurement.
Preferably, when emission switch 3 is opened, connected inside the air storage chamber 2, emission switch 3 and gun tube 4, group
Into the compressed air gas circuit of Portable gas gun device.
Preferably, the air storage chamber 2 is cylindrical shape, after the completion of inflation, can depart from external air source or air compressor and list
Solely work.
