The task of an high-altitude simulation test facility is to provide this ambient pressure of around 2 millibars for the ignition of the engine and to maintain it even when the engine is running.

He tells me he came up with the idea after reading research on breathwork as high altitude simulation training, which traditionally has involved more complex practices such as wearing a high ...

Significant modifications were made in 2002, converting test position P4.1 from a test stand for testing upper stages under atmospheric conditions to a high-altitude simulation test stand. This ...
