Abstract
Microsatellites are now in vogue in the world and propulsion will be desired for the more complicated space mission with them. We have been devoting ourselves to develop a propulsion system based on hydrogen peroxide solution with middle-level concentration and tested it for several years, and are now working on price reduction of the propulsion system with the view of a budget of satellite development. One of the key elements of the propulsion for the price reduction is a bladder to pressure liquid propellant, and we confirmed a COTS bladder is practicable with respect to storage performance of hydrogen peroxide and application way of pressure in this study.
