With a great help of past advisors, collaborators, and past/current students, the author has contributed to aerodynamic understanding of Japanese rockets, i.e., Epsilon Launch Vehicle and Reusable Launch Vehicle, through construction of numerical methods for compressible flows such as Simple Low-dissipation Advection-Upstream-splitting-method (SLAU) and SLAU2. This manuscript briefly looks back these topics: 1) SLAU and SLAU2 were designed to handle both low-speed and high-speed flows without experts’ care, 2) The Epsilon aerodynamics, specifically its roll-moment, was accurately predicted at the early stage of the development, 3) The effects of protuberance on slender-bodied rockets are being studied, and 4) The very high angle-of-attack aerodynamics of launch vehicles is also being surveyed for their reusability.
