Experiment ID
| LH2-Tank rupture tests
|
Short Description
| Tanks for cars with liquid hydrogen up to 70 l were ruptured at the top and the instantaneous jet ignited: high speed cinematography, pressure measurements and radiation measurements at distances of about 20 - 22 m
|
What phenomena were studied
| Tables, graphs of Pressure, radiation intensity, temperatures depending on time
Films of the events
