Experiments have been carried out to examine the combustion characteristics of propane-air mixtures under normal gravity and microgravity conditions by using high ignition energy in a combustion tubę. The microgravity technique achieved in a freely falling chamber is employed because the realizations of symmetrical flame propagations in a tubę are possible. Experimental condition for the initial mixtures corresponds to room temperature and 0.1 MPa and the fuel used is propane of 99.9% purity. The main conclusions are as follows: (J) The flame speed monotonically decreases with decreasin the equivalence ratio under normal gravity and microgravity. (2) The probability of the irregular flame propagation for both fuels under microgravity are larger than that under normal gravity at same equivalenence ratio. (3)The range of distance of flame propagation under normal and microgravity conditions by using high ignition energy can possible to distinguish.
