Design and test of refillable start-basket surface tension PMD

The working principle of the start-basket surface tension PMD is described. A simulation model of the refilling process of the refillable start-basket is established and the factors which affect the refilling process are analyzed. A test sample was manufactured, and then the static and dynamic refilling tests were carried out. The test results have a good agreement with the simulation tests, which indicates the validity of the simulation model. The design, manufacture and test technology of the refillable start-basket have been mastered preliminarily. The design is important to develop the tank used in restartable propulsion system.
