Overview of the laboratory
Philae landing tests
Tests on one leg
The modular testbed (Landing and Mobility Test Facility – LAMA) was established at the DLR Institute of Space Systems to support the development of landing systems. The aim is to study how landing systems work in real-life simulations, depending on their weight, dynamics and the planetary surface. Important issues to be addressed include stability when landing on an inclined surface with lateral speed, and safety when landing on rough terrain. These issues can often elude reliable numerical simulations due to little knowledge about granular surface materials and their behaviour during dynamic phases of motion.
The LAMA facility will feature a reproduction of a planet's surface complete with granular soil and arbitrarily placed stones. An encasement measuring 10 metres x 4 metres will house this simulated planetary surface. It will also be possible to introduce an inclination in the terrain (up to 30 degrees) to simulate landing on a slope and uphill / downhill travel. Another key element of the facility is a mobile industrial robot system with a load capacity of up to 500 kilograms, designed to ensure accurate control of the test object (sample).
Landers can be thrown during a drop test with predefined speeds and angles.
Alternatively, a permanent connection with the robot system means that they can also be moved whilst relieved of weight.
In addition to the tests at the system level, component tests can also be carried out on individual landing gear legs
