Abstract

A free piston driven Ludwieg tube is introduced that enables the simulation of flows of high Reynolds and Mach numbers at high stagnation temperatures. The test time is longer than in other hypersonic facilities operating under similar test conditions as, for example, in shock tunnels. The test gas is unsteadily compressed and heated thus reducing the thermal loads to the walls. It is shown that the free piston driven shock tunnel HEG of the DLR at Göttingen can also be run in a free piston driven blowdown tunnel mode.
