A pulsed detonation combustor (PDC) is a constant volume combustor operating under oscillatory conditions, based on the so-called Humphrey cycle [1], which is significantly more efficient than the constant pressure combustion, Brayton cycle, typical for the modern gas turbine engines [2]. If a detonation wave is used instead of a regular flame to burn the combustible mixture, as in a PDC, the speed of the burning process increases by several orders of magnitude and the thermal efficiency further increases [3,4,5]. A detonation wave can be regarded as a shock wave coupled with a combustion wave. Even though detonation has been studied starting from the XIX century, detonation has become of significant interest for the combustion research community in later years. However, to the date, the operating frequency of PDC’s reported in the literature remains in the region of several tens of Hz [2]. Earlier studies [4,5] have shown that the efficiency of a PDC based engine is directly related to the PDC operating frequency. To address this issue, a valveless PDC design, shown in Figure 1 (centre and middle), is proposed. The admission of air into the PDC is, in this case, controlled aerodynamically, by means of a system of oscillating shock waves generated by Hartman resonators placed inside the PDC. The testing of the PDC experimental model showed that strong and reasonably regular (in both frequency and amplitude) detonation waves are obtained inside the PDC experimental model. The shape (left) and the frequency (right) of the detonation waves are presented in Figure 2. The operating frequency of the tested PDC is found to be of 100 Hz, s shown in Figure 2.
