The DLR Bremen with the Kryo Lab as testing facility provides the service of both static and dynamic cryogenic tests with the cryogenic test demonstrator (CTD). These tests are part of the FLPP3 program and have to be made with liquid nitrogen (LN2) as testing fluid and both gaseous nitrogen (GN2) and gaseous helium (GHE) as pressure gas. The former test campaigns estimated the damping and frequency characteristic of the cryogenic liquid in WP31320 [RD2] as well as the cryogenic static behavior during filling, draining and stratification conditions in WP31330 [RD3]. Being the last part of FLPP3 the actual test report within WP31340 finally deals with the pressure development during sloshing. In this context test aim of this test campaign is to analyze the pressure development inside the test vessel with respect to different levels of dynamic excitation and ullage gas mixture. All tests were performed with a thermally chilled tank. During testing pressure level, gaseous flow rates, wall- and fluid temperatures, liquid fill levels, gaseous helium concentration in the ullage and tank acceleration are recorded. Additionally the tank camera system provides an overview video of each test.
