Abstract
A method for the degassing of hypergolic propellants includes introducing hypergolic propellant into a vacuum-tight vessel, cooling the vacuum-tight vessel containing the hypergolic propellant, and applying a pressure that is reduced as compared to the atmospheric pressure to the hypergolic propellant.
Claims7
A method for the degassing of hypergolic propellants, comprising:
- introducing hypergolic propellant into a vacuum-tight vessel;
- cooling the vacuum-tight vessel containing the hypergolic propellant, thereby cooling the hypergolic propellant;
- applying a pressure that is reduced as compared to the atmospheric pressure to the hypergolic propellant before the temperature of the hypergolic propellant reaches the freezing point;
- and
- maintaining the pressure that is reduced as compared to the atmospheric pressure at least temporarily while further cooling the hypergolic propellant to the hypergolic propellant freezing point.
