摘要

Reentry technology is a key technology for future reusable launch and space transportation vehicles. In Europe, several technology programs have been dedicated to this field throughout the last decade and before. Also some technology demonstration have been obtained with ballistic and semi-ballistic capsules like ARD, EXPRESS and MIRKA and an automatic landing demonstration with PHOENIX lately. No further experience has been gained, but only studies for demonstrators have been performed. Last but not least, the X-38 cancellation has taken away a real flight opportunity to prove technology of different fields. Especially, the last example included extensive work not only on materials and thermal protection system technology, but also on guidance, navigation and control (GNC). Due to the lack of flight opportunities the paper will describe a project of a reentry demonstrator, initiated at the Institute of Space Systems (IRS) within the Stuttgart small satellite program. The overall mission concept is presented as well as scientific and experimental topics. In comparison to other reentry experiments, the intended mission implies not a simple ballistic, but a lifting reentry vehicle to obtain demonstrating capability for GNC algorithms. Therefore, vehicle design including aerodynamic and aero-thermodynamic problems have to be solved. In opposite to conventional small satellite designs, a reentry mission will need a propulsion system to perform orbit transfer and deorbit.
