A composition that includes a fuel and a perfluoropolyether (PFPE) is disclosed. The composition may be used as a flare composition in a countermeasure device. Countermeasure devices including the flare composition are also disclosed, as are methods of forming grains of the countermeasure device.

The invention relates to a cast explosive composition, particularly to a pre-cure castable explosive composition comprising an explosive material, a polymerisable binder, a microencapsulated cross linking reagent, said microencapsulated cross linking reagent, comprising a cross linking agent encapsulated in a microcapsule.

The invention relates to a process for forming a pre-defined recess in a cured or cast explosive composition comprising the steps of: i) providing a female mould, ii) providing a male former, and locating said male former proximate to the female mould to create a gap between said male former and female mould, iii) forming an admixture of a curable/castable explosive composition, charging the gap with the admixture of explosive composition, causing the cure or cast of said curable/castable explosive composition, removing the male former to furnish a cured or cast explosive composition with a pre-defined recess.

A method for manufacturing a solid propellant includes: forming a tool of layers of a first material wherein cuts in the layers form a first interior chamber in the tool; using the tool to mold a second material in the first interior chamber; removing the molded second material from the tool; using the molded second material to mold an interior chamber in a rocket propellant grain; and removing the molded second material from the rocket propellant grain.

The present disclosure is related to the technical field of propellant performance research, and in particular, to a method for reducing propellant curing residual stress by a high-energy acoustic beam. The method includes the following steps: injecting a propellant slurry into a curing container and waiting for the propellant slurry to start curing; actuating, when the propellant slurry starts curing, a high-energy acoustic beam generator and a high-energy acoustic beam transducer to continuously emit high-energy acoustic beam to the propellant slurry in the curing container until the propellant slurry is cured to form a propellant grain; and closing the high-energy acoustic beam generator and the high-energy acoustic beam transducer. The method for reducing propellant curing residual stress by high-energy acoustic beam provided in the present disclosure can reduce residual stress inside the propellant in an effective manner, thereby ensuring operation safety of the aerospace equipment.

An in-situ process for synthesizing highly pyrophoric foam materials using metal and carbon precursors wherein the precursors serve as foaming and activating agents to disperse and lock nano-sized metal particles within a rigid porous carbon matrix. The resulting carbon matrix is also pyrophoric.
