Destruction Test of Small Scaled Solid Propellant Motors

概要

論文の詳細を見る
Destruction tests have been carried out on the ground by using three small scaled motors of solid propellant with a pair of destruction devices of V-shaped charge type. Each motor has the size of about 1/10 of the rear segment of one third of the 1st stage of Mu-3C that is a three staged and all solid propellant satellite launcher, developed by ISAS. Destruction devices in these tests are roughly the same in function and installation as those for Mu-3C. Several interesting results have been obtained on breakup characteristics of motor, such as mode of destruction, shapes of fragments of propellant and hardware, scattering distribution of them, shock load undergone by motor and surrounding overpressure. These results are expected to be useful for prediction of breakup characteristics of Mu-3C due to V-shaped charges.
