Testing of Boron Carbide – Zirconium-Based Solid Fuel in a Hybrid Gas Generator of a Ducted Rocket Engine

Abstract

The hybrid rocket fuel average regression rate is one of the most important variables that must be calculated in the hybrid rocket design process and for estimating rocket performance. There isn't a whole theory that can be used to predict this number, however. Quantifying data on regression rates is particularly difficult. A viable replacement for conventional propellants is the testing and assessment of boron-zirconium rocket propellant. It is a desirable alternative for next-generation rocket systems due to its distinctive qualities, including high energy density and little environmental effect. The testing procedures used to evaluate the propellant's performance, stability, and safety are explained, with an emphasis on the developments made and the difficulties faced throughout development. Two substances that have excellent qualities and have a lot of promise for cutting-edge applications are boron and zirconium. Numerous studies are currently being conducted on the use of boron and zirconium in aerospace materials, including improvements in fuel formulation, combustion efficiency, and structural materials, which show how boron and zirconium may be used to enhance the efficiency, security, and sustainability of hybrid ducted rockets. Understanding the testing process may help to shed light on the potential benefits and downsides of the propellant for future rocket applications.

Zirconium, charcoal, and paraffin wax are only a few examples of the boron-loaded polymeric fuels included in the present study. The regression rate is calculated for different propellant percentages in order to identify the ideal composition for a satisfactory regression rate.
