Abstract
An innovative Panel ExTension SATellite (PETSAT) and propulsion system for PETSAT, are presented in this paper. Based on PETSAT ethos, design policy of the propulsion system is provided. According to the policy, we designed propulsion system and concretely estimated and assembled mono-propellant and bi-propellant systems, and it indicated that mono-propellant propulsion with 50-60 seconds of specific impulse and 1 N of thrust is probable. In the case of bi-propellant, 120-150 seconds of specific impulse is valid even based on the design policy. We conducted captive tests of mono-propellant and bi-propellant propulsions with a breadboard model and flight model of propulsion system for PETSAT, and obtained good operations and performances. Now we are proceeding with its further improvements.
