| Summary: | Experimental investigation on a valveless pulse combustor that applies Helmholtz resonation
concepts is presented. The pulse combustor is attached with a J-shape inlet. Part of the burnt gases
mixes with inlet air in the J-shape inlet due to pulse action. Since the J-shape is in the same
direction as the tailpipe, it also produces additional thrust. The thrust produced is from 22.07 N to
31.88 N. The J-shape inlet increases the minimum required fuel supply. It also reduces the noise
that is produced by the pulse combustor. It is shown that the optimum range of fuel supply for the
pulse combustor is in the lean region. The effect of the J-shape inlet to the operating frequency is
the same as lengthening the tail pipe with a frequency of 125 Hz with the J-shape and 157 Hz
