Detailed explanation-1: -Liquid oxygen-abbreviated LOx, LOX or Lox in the aerospace, submarine and gas industries-is the liquid form of molecular oxygen. It was used as the oxidizer in the first liquid-fueled rocket invented in 1926 by Robert H.
Detailed explanation-2: -Cryogenic engine makes use of Liquid Oxygen (LOX) and Liquid Hydrogen (LH2) as propellants which liquefy at-183 deg C and-253 deg C respectively. LOX and LH2 are stored in their respective tanks.
Detailed explanation-3: -The LOX tank liner is manufactured by rotomoulding ETFE resin inside a steel negative mould. Most polymers, including ETFE, are somewhat permeable to oxygen. When the tank is pressurised with LOX, oxygen will diffuse through the liner.
Detailed explanation-4: -Liquid oxygen is a cryogenic liquid. Cryogenic liquids are liquefied gases that have a normal boiling point below –130°F (–90°C). Liquid oxygen has a boiling point of –297°F (–183°C).
Detailed explanation-5: -Liquid oxygen has a density of 1.141 g/cm3 (1.141 kg/L or 1141 kg/m3) and is cryogenic with a freezing point of 54.36 K (−218.79 °C; −361.82 °F) and a boiling point of 90.19 K (−182.96 °C; −297.33 °F) at 101.325 kPa (760 mmHg).
