- Abstract
The gas-filled pressure vessel in satellites will begin to leak or burst while it is collided by the Meteoroid/Orbital debris, which may lead to the satellite functional failure or decomposed. The thrust from the leakage gas can also deflect the flight attitude of satellites strongly. Therefore, it is very meaningful to explore the failure mechanism for the purpose of satellites application on the full-scaled pressure vessel in satellites. In this paper, the titanium alloy pressure vessel hypervelocity impact tests in satellites are presented with Two Stage Light Gas Gun under the shielding of the multi-layer insulations (MLI) and the carbon-fiber honeycomb panel, which simulates the configuration in satellites. In addition, the internal pressure 6MP in the gas-filled vessel and no internal pressure in the vessel are considered in the tests. The velocities of spherical projectiles with the aluminum alloy are kept 6.5Km/s constantly. Furthermore, the ballistic limits diameters are figured out by adjusting the various projectile diameters. Moreover, the test results applied in satellites are also analyzed in the paper.
