CHEMICAL ROCKET PROPULSION: A COMPREHENSIVE SURVEY OF ENERGETIC MATERIALS 545-575 2017年 [査読有り]
The demand for the economic and dedicated space launchers for vast amount of lightweight, so-called nano-/microsatellites, is now growing rapidly. There is a strong rationale for the usage of the hybrid propulsion for economic space launch as sugg...
Numerical analysis on the instability of liquid/dense fluid films under supercritical operating conditions is performed on methane fuel. A numerical code for compressible fluid flows, accommodated for the van der Waals equation of state, is develo...

In this paper, described is the development of a numerical simulation system, what we call "Advanced Computer Science on SRM Internal Ballistics (ACSSIB)", for the purpose of improvement of performance and reliability of solid rocket motors (SRM)....
For the last 50 years solid propulsion has successfully created a multitude of small launchers and many first stages or boosters for heavy launchers with low risk, high performance. competitive cost, superb storability, and "instant" readiness in ...

In order to handle increased demand of launch of ultra-small satellites in recent years, it is effective to simplify the handling of propulsion systems by eliminating hazardous nature of them. And a prime example of an essentially non-explosive pr...
Combustion instabilities in the low-frequency spectrum have been reported in several axially-injected hybrid rocket motors. In this paper, development of an unsteady computational model which can predict these instabilities is presented. The numer...
