Application of Amorphous Boron Granulated With Hydroxyl‐ Terminated Polybutadiene in Fuel‐Rich Solid Propellant

Amorphous boron powder granulated with HTPB, whose particle diameter could be controlled, was prepared by mechanical mill method. It was found that amorphous boron powder could be granulated with HTPB binder to form B‐HTPB particles, whose median particle diameter (d₅₀) and specific surface area are in the range of 125.0–431.0 µm and 0.02–0.1 m² g⁻¹, respectively. The B‐HTPB particles could be dispersed in the HTPB binder with relatively low viscosity compared with direct addition of amorphous boron powder to the HTPB binder. The experimental results showed that the content of boron particles in a fuel‐rich propellant could be increased by addition of B‐HTPB particles and the combustion characteristics of the fuel‐rich solid propellant could be improved.

Hypergolic Studies of Ethanol Based Gelled Bi‐Propellant System for Propulsion Application

The experiments conducted in this study examined the hypergolicity and ignition delay of the formulated ethanol gelled fuel and hydrogen peroxide oxidizer bipropellant system. The hypergolicity and ignition delay data for bipropellant system are very important for propulsion applications. It was observed that the ethanol based gelled fuel systems were hypergolic with hydrogen peroxide (90% pure) in a presence of a suitable catalyst. The observed ignition delay was within the range of 10∼50 ms, which was comparable with the existing liquid hypergolic bipropellant systems. Temperature profile also indicated that the hypergolic system attained a very high temperature profile range of 1000 °C to 1400 °C for a very small weight percent of fuel. Experiments conducted with two separate volumes of oxidizer, 14 μl and 50 μl. In both cases the propellant system was fuel rich. It was also observed that the formation of cage in the gel network, which could encapsulate the higher temperature gases and flame in a network, might be a plausible reason for recorded higher ignition delay.
