Strand Burner

Description

The Pulham Group specialises in studying the structure and properties of materials under various conditions, typically extremes of pressure and temperature. The overall objective is to determine how changes in structure or composition influence the resulting properties of the materials—be that their thermochemical balance, energetic sensitivity and performance, or suitability for use in car engines—to influence the design of better heat storage materials, safer explosives and propellants, or more efficient biofuels. As part of their ongoing research, the Pulham Group intends to procure a pellet/strand burner to investigate the performance of ballistic modifiers on the burn rate performance of solid rocket propellant compositions. A pellet/strand burner is required to measure the burn rate pressure profile which can show the performance of burn rate modifiers. Funding was awarded for this project to investigate alternatives to lead-based ballistic modifiers Lot 1: The Pulham Group specialises in studying the structure and properties of materials under various conditions, typically extremes of pressure and temperature.

A pellet/strand burner is required to measure the burn rate pressure profile which can show the performance of burn rate modifiers. Funding was awarded for this project to investigate alternatives to lead-based ballistic modifiers. To evaluate ballistic modifiers, the change in burn rate with pressure must be measured with a Crawford burner. A Crawford burner is a device used to test the burn rate of solid propellants. It can take the form of a pellet or strand burner.
