In the aerospace industry most of the current launch vehicle, payload and spacecraft designs utilize numerous pyrotechnic devices over the course of their mission. These devices are generally used to separate structural subsystems, deploy appendages or activate on-board operational systems.
Pyroshock is the oscillating response of a structure to a high frequency and high amplitude mechanical excitation. Therefore the Beyond Gravity Test Center is equipped to test mechanisms for pyroshock in a broad spectrum of frequency and amplitude.
The frequencies of the response can rise up to 20 kHz. They consist of resonant frequencies of the sample being tested. The peak acceleration can be as high as 10’000 g for weights up to 25 kg.
Please note: This maximum values depend on the specifications of the test pieces (weight, special dimensions, configuration, etc.).
Following standards are used in the Beyond Gravity Center:
- MIL-STD-810 Meth. 517
