The Effects of Material‐Filled Voids on Detonation Wave Shape in Rubberized RDX Explosives
Propellants, Explosives, Pyrotechnics, Volume 49, Issue 12, December 2024.Abstract The sensitivity of explosives is affected by inhomogeneities within the material. This is evident in the increased shock sensitivity of explosives with slightly lower densities resulting from an increased number of hotspots. The influence of hotspots on explosive initiation has been well studied; however, few studies have been conducted on the

Alternate propellants for the space shuttle solid rocket booster motors [PDF]
As part of the Shuttle Exhaust Effects Panel (SEEP) program for fiscal year 1973, a limited study was performed to determine the feasibility of minimizing the environmental impact associated with the operation of the solid rocket booster motors (SRBMs ...

The Synergistic Effect of Fe-Based MOFs and HTPB on AP Decomposition in Solid Propellants
SolidsMany factors and their mutual interaction between catalysts and AP/HTPB composite solid propellant induce the complexity in the combustion. Among them, we prepared two Fe-based MOFs as catalysts and investigated their catalytic effects and mechanism on ...

Switchable RDX‐Based Rubberized Explosive with Thermally‐Expandable Microspheres
Propellants, Explosives, Pyrotechnics, Volume 49, Issue 10-11, October 2024.Abstract Improving the safety of explosive materials through the synthesis of insensitive explosives has been studied extensively. However, little work has focused on creating switchable explosives. A switchable explosive is normally insensitive to detonation, and therefore safe to handle and transport, but can be sensitized when needed to create a ...

Investigating Premature Ignition of Thruster Pressure Cartridges by Vibration-Induced Electrostatic Discharge [PDF]
, 2010 Pyrotechnic thruster pressure cartridges (TPCs) are used for aeroshell separation on a new NASA crew launch vehicle. Nondestructive evaluation (NDE) during TPC acceptance testing indicated that internal assemblies moved during shock and vibration testing
