    Abstract: The ignition and combustion process of fuels in a supersonic combustion chamber plays an important role in the design of hypersonic propulsion system. However, it is a quite complicated process, due to the large variation of inlet air velocity, temperature, oxygen concentration, and shocks in the supersonic combustion chamber. The purpose of this paper is to observe the ignition delay and combustion phenomenon of the JP-8 fuel droplets in a supersonic flowfield experimentally. A shock tube is used as a basic test facility to create a high-speed and high-temperature flowfield as a supersonic combustor. In the experiments, several test parameters are controlled, such as shock velocity, gas temperature, fuel droplet size and distance, initial fuel temperature, and oxygen concentration, etc. The test results show the influence of these parameters on ignition delay, ignition limitation, and detonation. The most important factor in the experiment is the initial fuel temperature effect, which is influenced by the altitude variation during a flight.
