Emission imaging of AP/HTPB propellant sandwich combustion

Combustion Science and Technology, 2002
Ultraviolet emission imaging (305-315 nm) was used to study the combustion of sandwiches of ammonium perchlorate (AP) and hydroxyl-terminated polybutadiene (HTPB) in nitrogen at pressures up to 32 atm, with binder layers from 50 to 450 µm in thickness.

The Damage Law of HTPB Propellant under Thermomechanical Loading

Journal of Energetic Materials, 2015
By way of measuring the acoustic emission (AE) signals of Hydroxyl-terminated polybutadiene (HTPB) propellant in condition of uniform speed, and combined with the scanning electron microscopy (SEM) fracture surface observation, the damage law of HTPB composite solid propellant under thermomechanical loading was studied.

Accelerated Aging Tests of HTPB-Based Propellants

2018
In the late twentieth century, liquid and solid propulsion technologies have been integrated into hybrid engines currently apllied in propulsion launch vehicles and missiles. The reaction of polyol (HTPB) and diisocyanate (IPDI) provides the most versatile of the binders in the production of solid propellants due to its ability to withstand high loads ...

Investigation of Aluminum Agglomeration in AP/HTPB Composite Propellants

44th AIAA Aerospace Sciences Meeting and Exhibit, 2006
Aluminum flame conditions, burning surface structure, and surface regression rate of co mposite propellant laminates of aluminum powder, fine and coarse ammonium perchlorate (AP), and hydroxyl -terminated polybutadiene (HTPB) are experimentally investigated. An aluminum matrix consisting of 15 µm Al powder mixed with fine -AP/HTPB (76:24) is sandwiched

Infrared imaging of AP/HTPB laminate propellant flames

Combustion and Flame, 2008
Abstract The combustion of ammonium perchlorate (AP), hydroxyl-terminated polybutadiene (HTPB) two-dimensional laminate propellants is investigated using simultaneous infrared (IR) and ultraviolet (UV) emission imaging at 1–50 atm. The IR (3300–3900 nm) measurements sense flame presence nominally via HCl rovibrational excitation and the UV (310 nm ...

Structure‐property relationship of HTPB‐based propellants. I. Effect of hydroxyl value of HTPB resin

Journal of Applied Polymer Science, 1993
AbstractComposite propellants based on hydroxyl‐terminated polybutadience (HTPB) resin are the most common contemporary solid propellants for launch vehicle and missile applications. A series of HTPB resins, manufactured by free‐radical polymerisation using a peroxide initiator, with varying molecular weights and hydroxyl values, was used in propellant
