EEE Parts Selection Idea For The Advanced Solid Rocket
JAXA has undertaken the research on the next generation solid propellant launch vehicle called the Advanced Solid Rocket (ASR). The ASR consists of the three-stage solid propellant launch vehicle and the major aims are to have the ability for launching of 1.2 metric tons in the low earth orbit and to establish low cost and short period launch operation. In order to respond to the demands of small satellites flexibly, the ASR aims for the establishment of correspondence to various orbits, mitigation of the payload mechanical environments, such as sound environment and a separation shock, and correspondence to a short period of time and a quantity frequency launch. Reliability will be improved by sharing and strengthening of the infrastructure with the H-IIA rocket which is currently-operated and the H-IIB rocket under development. Furthermore, cost reduction will be established by pursuit of the ground equipment simplification, the efficiency of the launch operations and balance with the advanced technologies. The new launch processes with high operability will be established by shortening of the period for the rocket assembly operations. As the avionics polices, the launching system innovation and the development toward the next generation standard technologies have been determined to apply the ASR. And we plan to secure the reliability by establishing the appropriate parts quality as the ASR in accordance with the past results of the H-IIA rocket development. In addition, we plan to establish the infrastructure technologies strengthening and cost reduction by minimizing the part kinds to be used for the avionics equipments.
