Investigation of hybrid rocket motors

Hybrid rocket motors contain a solid, inert fuel element and an oxidant that is pumped into contact with the fuel. This configuration is distinct from a liquid rocket where both the fuel (hydrogen) and the oxidant (oxygen) are mixed or a solid rocket where the fuel and oxidant are combined in the propellant grain. The research group at the University of Arkansas at Little Rock investigates fundamental aspects of combustion in hybrid rocket motors, for example thrust oscillations, pressure, plume flicker and acoustical output.
