Keynote title:
Research on Novel Landing Mechanisms for Their Implementation in Lunar/Planetary Exploration Spacecraft in the Near Future
Abstract
Currently to suppress the effects of impacts on landing of lunar/planetary exploration spacecraft, most devices use the process of plastic deformation of the cushioning material similar to bumpers on an automobile. The body of the landing probe of Apollo’s lunar lander also suppressed impact by using plastic deformation in a honeycomb design. However, in order to obtain highly reliable mechanisms at low costs, a shock response control mechanism that can be re-experimented on is necessary, instead of a crushing shock suppression mechanism. For this purpose, we have proposed two ideas and their applicable mechanisms – the momentum exchange type and the energy exchange type. This talk introduces the effectiveness and features of the methodologies based on these two ideas.
