Energy conversion efficiencies of approximately 40% can be achieved in today’s gas turbines by the utilization of various design methods and materials. However, the main part of the primary energy used is still lost in form of heat, thereby producing greenhouse gases. It is common knowledge that after significant improvements in the past only marginal steps can be expected in the future for the classical design of a machine. Hence, only radical changes offer new opportunities. It is the vision of this Collaborative Research Center to increase the efficiency of a gas turbine by more than 10% by the exploitation and control of a combination of innovative combustion concepts and unsteady characteristics of a machine.

The major contribution to an efficiency increase is expected from a thermodynamically motivated move from a constant-pressure to a constant-volume combustion. This will be done with the more classical pulsed detonation as well as with a new shockless explosion concept. A pulsed combustion, however, will give rise to severe consequences with respect to a stable operation of the compressor or a reliable cooling of the first stages of a turbine, to name just a few challenges. To control these implications flow control methods either passive or in closed loop will be applied. These flow control methods will be built up in such a fashion that they offer an additional increase in efficiency which can even be used in a classical gas turbine as well.
