GOX/GH2 is all too likely to detonate instead. Maybe if the mixture ratio
was way off center?
GH2/GO2 mix was used in a massive chamber horizontal gas gun with a small
caliber barrel ±10 m long. To avoid explosive compression of He or GH2
"light gas".
Off centre? Non-stoichiometric you mean; mix ratio was stoichiometric IIRC.
Deflagration or detonation who cares? It worked. Years ago I sent pictures
of that eighties lab contraption in Moscow to AR. Twice. The aluminum
projectiles in part melted when hitting the atmosphere beyond the vacuum
barrel. Go figure. Too old a website for Google.
