Title：A new paraffin-based hybrid propellant formulation designing
and its burning performance research
Abstract:
Hybrid rocket engine becomes a very attractive way of the general suborbital flight and space exploration mission,because of its high security nature,low-cost, adjustable and other properties,but its development and application has been restricted by low regression rate.Paraffin-based fuel has high regression rate,its regression rate is 3-4 times the HTPB fuel under the same experimental conditions,at the same time,paraffin-based fuel has low requirements for processing,storage and transport which made it become the ideal energy of hybrid engine,but the wax is poor of mechanical properties and is prone to brittle deformation,thus we should ensure the combustion performance at the same time to improve the mechanical properties as much as possible.The new type of particle-paraffin-based composite fuel designed in the reserach, realized a greater degree of increasing fuel retreat rate, and enhanced its mechanical properties.This research was carried out to study the mechanical and combustion properties of particle-paraffin-based composite fuel,preliminary master its combustion characteristics.The results show that the regression rate and the oxidizer mass flow both to meet the power function,the higher the mass fraction of the polymer particles or the bigger the particle size ,the higher regression rate, provided the theoretical reference of its application in hybrid propulsion.
