Hayabusa2 Asteroid Sample Return Mission: Technological Innovation and Advances 433-452 2022年1月
In this chapter, the development procedure and the operation of Hayabusa2 bipropellant chemical propulsion system are described in detail. Lessons learned from the original Hayabusa (sample return mission from the asteroid Itokawa) and Akatsuki (V...
HAN-based liquid monopropellant has been studied for its possible substitution of hydrazine toxic component. The onset temperature of decomposition was provided by DTA-TG thermal analysis. Moreover, the effect of 5M HNO3 and 5M NH2OH addition on c...
HAN-based liquid monopropellant is considered as promising alternative for hydrazine toxic system due to its high specific impulse, high density and low freezing point. During the application for HAN thrusters for reaction control system and green...
Most mono-propellant thruster technologies were developed in the 1960s. Those basic principles and fundamental mechanisms, such as the catalyst and propellant, are still in use without major technical innovation. However, much remains to be clarif...
