Characterization of Improved Wax-based Hybrid Propellant in Hybrid Rocket

P K Dash, Jhumki Nandy, Shruti Giri

Abstract


In this paper, an experimental investigation on mechanical and combustion properties of wax-based hybrid propellant with additives has been carried out. Different types of additive compositions like Steric acid (ST), Araldite and Hardener, LDPE, EVA and Carbon Black are processed with Paraffin wax with pre-determined weight percentage. Assembling eight different types of the composition of paraffin wax, stearic acid, Araldite, hardener, LDPE, EVA, and Carbon black, the propellant grain is structured for mechanical characterization. A selection of three different compositions has been done after mechanical characterization with the merit of low strength, average strength and high strength are selected for further identification of hybrid propellant characterization, i.e., calorific value, regression rate and compositional character inside rocket motor. The stress-strain measurement of these eight samples under tensile loading was recorded. Based on the mechanical observation, three compositions based on low to high strength and regression rate are noticed. The mechanical characterization of the propellant had shown that the tensile properties varied from 109MPa to 225.62MPa. Out of those, three groups of composites have shown improved mechanical properties (0.806MPa,0.902MPa, and 1.386MPa) and are further processed for static firing tests. As per static firing result for virgin as well as modified paraffin composition recorded, an observable improvement on propellant behavior on regression rate is noticed. Although the improvement of modified wax-based hybrid propellant about 107% and 21% improved regression is obtained.
