LAUNCH VEHICLE UPPER STAGE AMPOULIZATION AS A MEANS OF PAYLOAD CAPABILITY IMPROVEMENT

摘要

Advantages of ampoulization usage are given for upper stage propellant compartment with intermediate dome. Areas of stage modification are chosen, efficient pressures in the cavities of propellant compartment, as well as reliability indexes of filling and draining operations are determined. The given measures complex has ensured a considerable increase of the injection payload capability.
