Résumé

Cooled liquid oxygen (non boiling) is used as a cryogenic component of fuel in space apparatus. It has lower temperature than its boiling temperature at atmospheric pressure, hence its density is high. Thus it allows increasing liquid oxygen reserves in a space apparatus tank. That's to say that the equal capacity tank is filled with more product mass and product losses at storage and fillings are substantially decreased. Liquid oxygen cooling in stationary conditions is carried out in both ways: stationary reservoirs and special devices (heat-exchanging apparatus, cooling reservoirs). The results of analysis of liquid oxygen cooling conditions and storage are given. In this case liquid nitrogen is used as a cooling reagent. Nitrogen is cooled by means of vapour space vacuuming on liquid surface with the help of ejectors. The constructive solution of tank-reservoirs for cooled liquid oxygen is given.
