Abstract
A joint research team of universities and private companies in Hokkaido, Japan has been organized to develop a small-scale reusable launch system based on CAMUI hybrid rocket. The main purpose is to drastically reduce the cost of rocket experiments and thus attract potential users such as metrological and microgravity researchers. The meteorological observation model of 400-kgf class motor is under development and a launch test in 10 km altitude is planned. Anomalous combustion occurred in the last four static firing tests out of seven serial tests with a flight model motor. This anomalous combustion is a specific phenomenon in the flight model engine and is not caused by the CAMUI method itself. Development testing to overcome this problem is under way and resumption of the launch program will follow.
