A solid rocket propellant includes a hydroxyl-terminated polybudadiene (HTPB) binder system having a high molecular weight diol that is greater than thirty carbon atoms (>C) and less than fifty carbon atoms (<C) and excluding dimeryl diisocyanate (DDI).

Solid rocket motor having hydorxyl-terminated binder weight diol

A solid rocket propellant includes a binder that has hydroxyl-terminated polybudadiene (HTPB) with a curative that is selected from isocyanate-terminated polyether, isocyanate-terminated polysiloxane, or combinations thereof.

Solid rocket propellant with low glass transition

A method for enhanced validation of an entity associated with a COF token includes: storing at least transaction data, a token requester identifier (TRJD), and a COF token identifier; receiving payment credentials, wherein the payment credentials include at least a COF-specific payment token; generating a transaction message, wherein the transaction message is formatted based on one or more standards and includes at least a plurality of data elements including at least a first data element configured to store the COF-specific payment token, a second data element configured to store the COF token identifier, a third data element configured to store the TRID, and one or more additional data elements configured to store the transaction data; and electronically transmitting the generated transaction message to a financial institution via a payment network.

Additive for solid rocket motor having perchlorate oxidizer

An end-burning grain of a solid rocket motor or other gas-generating device is supplemented with one or more sticks of high-burn-rate propellant embedded in a matrix of a relatively low-burn-rate propellant. The sticks increase the burning surface area as the grain burns by forming conical indentations in the surface.

End-burning propellant grain with area-enhanced burning surface

A propellant includes a binder system that has a polybutadiene component, a polytetrahydrofuran component, and an anti-oxidant component. In an example, the propellant includes a solid oxidizer, a solid fuel, and a binder system that holds the solid oxidizer and the solid fuel together. The binder system includes a polybutadiene component, a hydrocarbon diluent component of a higher level of saturation than the polybutadiene component, and an anti-oxidant component.

Propellant with extended storage life

Propellant compositions containing cyclic nitramines that are susceptible to unintentional detonation are desensitized by the incorporation of a linear nitramine having a backbone containing one to three ethylene groups and one or two nitramine groups.
