<p>methods of filling spacecraft with propellant; charging propellant tank of spacecraft with propellant, such as hydrazine from combined filling module. SUBSTANCE: combined filling module includes propellant transfer tank 14, vacuum tank 12 and compression agent tank 16. Propellant transfer tank 14 is transported to filling module at launching site. Prior to launch, filling module is connected to spacecraft 50. Propellant is transferred under action of compression agent to spacecraft tank 52. Compression agent builds up flight pressure in propellant tank 52. Remaining propellant is removed from joint 45 and from propellant transfer lines 42 by means of vacuum tank 12. EFFECT: reduced probability of propellant leakage. 10 cl, 2 dwg</p> |
