- Abstract
An innovative propulsion system for microsatellites based on SAFETY FIRST policy, are presented in this paper. The propulsion system is available for the ways of small impulse bit and large delta-V applications, due to have operabilities of both mono- and bi-propellant propulsions. We estimated its performance by CEA, resulted in probabilities of 60-second Isp for mono-propellant and 150-second for bi-propellant even based on the non-toxic propellant policy. We conducted captive tests of mono-propellant and bi-propellant propulsions with a breadboard model for microsatellite, and obtained good operations and performances. We once established such a propulsion system in the project of SOHLA-2 Microsatellite by Space Oriented Higashiosaka Leading Associations(SOHLA), but handleability was not so good in the system. We proceeded its improvements and succeeded its compactification which indicated that the system has more capability of propellants and availability of larger delta-V. Now we are proceeding with its further improvements.
