Ultrasonically Accelerated Nitration of Hydroxyl-Terminated Polybutadiene: Process Efficiency and Product Characterization

Eng
Hydroxyl-terminated polybutadiene (HTPB) is widely studied and the most used prepolymer for the binder system of composite solid propellants. A suitable functionalization of HTPB with energetic groups greatly improves the performance of the propellant ...

Effect of AP/rGO/Al Solid Loading on Interfacial Interactions, Microstructure, and Crystalline Phase Stability in HTPB-Based Composite Solid Propellants [PDF]

EPJ Web of Conferences
Optimizing solid loading is critical in developing composite solid propellants; increasing the solid fraction maximizes active phase contributions but risks degrading binder wetting and interfacial stability.

ADN Solid Propellants with High Burning Rates as Booster Material for Hypersonic Applications

, 2022
RAM- and SCRAM-Jet engines can not generate static thrust and only work at high speeds. This starting velocity of the motor v0 is usually generated by carrier rockets or boosters, which mostly use solid propellants based on ammonium perchlorate (AP) and ...

The effect of reactive plasticizer on viscoelastic and mechanical properties of solid rocket propellants based on different types of HTPB resin

Defence Technology
Conventional plasticizers deteriorate mechanical and viscoelastic properties of the propellants due to their migration upon aging and long-term storage, which affects reliability and safety properties during exploitation.
