Design And Implementation Of An Emission Spectroscopy Diagnostic In A High-pressure Strand Burner For The Study Of Solid Propell
… an oxidizer. The powders were held together with Hydroxyl-Terminated-Polybutadiene (HTPB), a hydrocarbon polymer that is solidified using a curative after all components are homogeneously mixed. The other two propellants did not contain aluminum, but rather relied on the HTPB as a fuel source. The …

Degradation and stabilisation of diisocyanate cured polybutadiene
Hydroxyl terminated polybutadiene (HTPB) has been used as a rocket propellant binder which is required to be stored for at least twenty years. It is found that the excellent stress-strain characteristics of this propellant can be totally lost, during this long storage, due to the deterioration of …

Investigation of Fuel Geometry and Solid Fuel Combustion for Solid Fuel Ramjets
… of polymethylmethacrylate (PMMA) and hydroxyl-terminated polybutadiene (HTPB). Investigations using two lab-scale SFRJs were conducted to determine the feasibility and performance impacts of implementing a cavity-style flame holder as a means of improving the flammability limits of a …

Rheology of Filled and Unfilled Polyurethanes for Reactive Extrusion-Based Applications
… in the form of a thermosetting reaction between hydroxyl-terminated polybutadiene (HTPB) and isophorone diisocyanate (IPDI). When uncatalyzed at room temperature, full conversion takes place over the course of multiple weeks which necessitates an accelerated kinetic analysis. Hence, a combination …

Composite propellant combustion with low aluminum agglomeration
… unique, wide-distribution, ammonium perchlorate/hydroxyl-terminated polybutadiene (AP/HTPB) propellant formulation that results in low Al agglomeration, even at low pressures (1-30 atm). Variations in formulation—such as fine-AP/binder ratio, Al particle size, Al loading, coarse-AP size—are also …
