RÉSUMÉThe combustion behaviors of three formulations of very high burning rate (VHBR) propellants are being studied. These formulations contain 0, 2, and 4% boron hydride, B10H10, the burning rate catalyst. Two diagnostic tools were used in this study: a realtime X-ray radiography (RTR) system with a high-pressure double-windowed (HPDW) test rig and a pressure and temperature controlled optical strand burner (OSB). The RTR system is used to obtain instantaneous X-ray images of the solid propellant grain as it burns during a transient test at pressure up to 340 MPa (50,000 psi). The optical strand burner maintains a steady pressure up to 41.4 MPa (6,000 psi) and allows the initial temperature of the strand to be set from −40°C to +70°C (−40°F to + 158°F).
