• This paper presents atomization characteristics of a double impinging F-O-O-F type injector with four streams. A phase doppler particle analyzer was employed to measure the droplet-size and water was used as the inert simulant liquid instead of reactive propellant liquids. The droplet mean diameter(SMD) and size distribution were measured to investigate the effects of the momentum ratio of fuel and oxidizer. The SMD distribution appeared to be the largest at MR=2.12(r=2.00). The difference between <SMD>^^^- at x=50mm and at x=100mm reduces as the momentum ratio increases. Droplet size distributions measured in the impinging spray flow field coincide well with all size distribution functions. MMD and D_<0.632> decrease as the momentum ratio increases. This experimental results can be used at the preliminary design stage of an impinging stream type injector for the liquid rockets.
