Abstract

The Automatic Landing Flight Experiment (ALFLEX) was conducted in Woomera, Australia, in 1996 in order to develop the automatic landing technology required for the future Japanese unmanned spacecraft, HOPE. In order to ensure successful landings, computer simulation played an important role in the preflight analysis. Monte Carlo Simulation was applied for the analysis. The Root Sum Square (RSS) method, which is commonly used in Japanese launcher rocket development projects, was also applied. Monte Carlo results were compared with the RSS results and the flight test results. All 13 flighttests were successfully completed. Longitudinal guidance in the flare phase was found to be sensitive to some modeling-errors. The cause is discussed.
