Evaluation of the Linear Serospike SR-71 Experiment (LASRE) oxygen sensor

“…3). 2 The limits remained about the same throughout the LASRE flight envelope, extending up to 50,000 ft. 3 Calculation of combustion conditions at equilibrium or for detonation showed that, even for low flammable concentrations of hydrogen and oxygen, temperatures and pressures high enough for structural damage could develop. A conservative ground rule stated that the oxygen and hydrogen concentrations must be maintained below 4 percent during the entire mission, because any combustion in the pod was deemed unacceptable.…”
