Abstract
A new concept for accelerating stoichiometric hydrogen-air mixtures to superdetonative velocities in an expansion tube using a Ludwieg tube as hydrogen reservoir is the subject of this paper. With this special set-up hydrogen/air gas mixtures can be successfully accelerated to a flow having a superdetonative speed with a static pressure of about 200 kPa at 350 K. The experiments in the expansion tube are carried out for basic research purposes on ram-accelerator-related combustion phenomena and also for supporting and optimizing the operation of the 30 mm and 90 mm ram accelerator facilities at ISL. Problems encountered while using an expansion tube for this purpose and some preliminary experiments performed with this new facility will be discussed.
