Effect of Ageing on Mechanical Properties of Composite Solid Propellants
WebDec 1, 2024 · The choosing of propellant type is at the core of any solid rocket motor design. The desirable characteristics for a solid propellant are high specific impulse, predictable and reproducible burning rate and ignition characteristics, high density, ease of manufacturing, low cost, and good aging characteristics. WebThe latter propellant clearly follows the classic "de Saint Robert" model of burn rate behaviour, with which burn rate may be represented by a single power function equation over the full pressure range. In this model, where (ro usually taken as zero), the pressure exponent n is the slope of a straight line on a Log pressure-Log burn rate plot ... inward-looking country
