An injector-combustor assembly and a dedicated flow system, currently under construction, are described which allow the photography and spectroscopy of liquid propellant spray combustion in high pressure and temperature clear inert gas environments. The gas is pressure regulated from a room temperature reservoir and is heated convectively in a particle bed heater prior to entering a windowed chamber combustor. The unique particle bed has a heat capacity of 0.67 calcm C and up to 2 KWcm power density for gas heating. Typically, steady state gas flow pressure and temperature are obtained in the combustor after 1 sec for a duration of 4 sec with downward velocities of less than 1 msec and temperatures ranging from 400 C to 800 C for pressures of 10 MPa to 69 MPa.
