Solid-propellant erosive burning

Journal of Propulsion and Power, 1987
A modeling approach based on experimental verification for the erosive burning of ammonium perchlorate composite propellants is proposed. It retains the idea that erosive burning is due to the penetration of the flow turbulence within the flame height and to the consequent enhancement of the transport coefficients and of the heat flux to the surface ...

Erosive burning research

22nd Joint Propulsion Conference, 1986
A status report is given on the results for the completed tests in a series of motor firings being carried out to measure the effects of the parameters that are considered to most strongly influence the scaling to larger rocket motor sizes of the transition to/or threshold conditions for erosive burning rate augmentation.

Erosive burning. Modeling problems

Combustion, Explosion, and Shock Waves, 2007
Existing models for the erosive burning of homogeneous energetic materials ignore the fact that the burning regime can be changed radically by exposure to a hot gas blowing over the burning surface. In other words, transition can occur from the gasification regime at very high blowing rates (where the burning rate is determined primarily by the heat ...

Erosive Burning of Solid Propellants

48th AIAA Aerospace Sciences Meeting Including the New Horizons Forum and Aerospace Exposition, 2010
We examine the combustion response of homogeneous and heterogeneous solid propellants to an imposed velocity field, as a model for erosive burning. The imposed velocity field has its roots in a multiscale analysis of a solid rocket motor. For homogeneous solid propellants we show that for certain realistic choices of the parameters both positive and ...

Erosive and strand burning of stick propellants. II - Theoretical modeling of erosive-burning processes

Journal of Propulsion and Power, 1990
Interior ballistic performance of unslotted single-perforated stick propellants in a large-caliber gun could be influenced significantly by erosive burning. To analyze erosive-burning phenomena, a comprehensive model, with special emphasis on the interaction of turbulence and combustion, was formulated to simulate erosiveburning processes occurring ...

Erosive Burning: Landsbaum Revisited

46th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2010
Operational erosive burning models are examined for hydraulic diameter scaling capability. Models based on the Reynolds-Colburn analogy cannot robustly scale hydraulic diameter e.g. it is a Prandtl number phenomena. Landsbaum's innovative approach to hydraulic diameter scaling with incompressible velocity profile information is re-examined as a ...
