Identifiers: Oxygen systems.An invesigaion was made of the relative afety of 7500-psi gaseous oxygen sytes when sed as a sorce of brething oxygen in aerospce vehiles. Experiments were performed to invesigte the effes on the system of temperure, vibration, shok, extended storage, and conmination. lso tudied were the effects of high pressure, high-velocity flow, and heing due to apid compression. Evaluation of the resuts of this progm inates tht 7500-psi gseous oxygen sytems an be compratively afe if proper afety pretions are taken. nder conrolled opeations, the had of exploion bese of conaminaion can be overcome. sinless steel and onel loys were found to be aceptable mterias of contrucion. eflon and Kel-F compouns appear to be uitable for seals. Hydroarbons in minte concenion were found not to be dangerously reacive. ELECROSTC CHRGES UE TO HIGH-VELOTY FLOW WERE SL, BUT THERE WAS EVDENCE THT EROION COULD BE A SERIOS PROLEM. (ATHO)
