ABSTRACT

An eco-friendly higher solid loaded HTPB propellant with improved energetics has been realized in small scale by incorporating 10−20% by weight of a high energy material namely, HMX. This propellant with 88% solid loading has given good processability, mechanical properties and reduced pressure index. Pollution due to HCl smoke in the rocket exhaust is reduced by 20 to 30% by weight. This propellant is expected to give a vacuum specific impulse of 293 seconds at an operating pressure of 70 ksc and an area ratio of 10. Sub Scale motors of 2kgs size have been successfully static tested to evaluate the performance.
