The rocket test facilities at DLR Lampoldshausen can be divided into two different systems: the first group conducts tests under ambient conditions (sea level tests). The second group uses special altitude systems for rocket aggregates and serves to simulate pressure conditions that really occur during rocket launch (altitude simulation tests).
Tests on the development, qualification and flight acceptance for small propulsion engines with 200 or 400 newton thrust are executed on the altitude simulation test facility P1.0 for propulsion engine manufacturers. The altitude simulation test facility P4.1 for high-performance liquid hydrogen/liquid oxygen (LH2/LOX) upper stage engines of ARIANE 5 is used for the development of new upper stages. Currently, we are testing VINCI, the new European upper stage engine. The altitude simulation test facility P4.2 is laid out for qualification and flight acceptance tests of AESTUS, the upper stage engine of the ARIANE 5 launcher.
Further tests on technical development, qualification and flight acceptance are planned on test facility P5 for the VULCAIN engine of the ARIANE 5 main stage. Research and technology test series are continued on the high-pressure test facility P8 for cryogenic hydrogen/oxygen rocket propulsions as European co-operation.
