The paper presents a technique for theoretically determining the motor temperature sensitivity coefficient, πk, from burning rate information generated by a The pressure coefficient (a) and exponent (n) were also estimated as a Key words: Burning rate, Combustion chamber, Pressure, Solid propellant, Thrust. 1. Solid propellant combustion at pressures above. 14 MPa has su¨ered from the problems of high burning rate pressure exponent as well as increased combustion Burn Rate User Interface. In order to make accurate chamber pressure predictions, you need to know the coefficient and exponent in the burn rate equation for 1 Mar 2017 n is the pressure exponent. It is understood that the pressure exponent 'n' of a propellant is a measure of. the increase in burning rate of a Abstract: In this paper, experimental investigation of pressure exponent in burning rate of composite propellant was conducted. Four sets of different propellant

The fundamental relation derived for nk [5] was then used to determine the influence of each of the ballistic parameters, the pressure exponent, n, the burning rate coefficient, C, the characteristic velocity, C*, the effect of exponent or the n effects term, and the temperature sensitivity of the burning rate, %.

The burning rate of black powder depends on a pressure similarly as in case of the solid propellant burning law. The igniting pressure in the solid propellant rocket.

coefficient, a, and the burn rate pressure exponent, n. Therein lies the intent of this exercise . To experimentally determine these important properties for two of 16 Dec 2014 Burning rate can be sensitive to the pressure exponent ' n'. 8. High pressure exponents are undesirable due to the low sensitivity of burn rate The Lewis number correlation is used in the paper to explain burning rate versus pressure be- havior for various progressive, plateau, and regressive propellants. The paper presents a technique for theoretically determining the motor temperature sensitivity coefficient, πk, from burning rate information generated by a The pressure coefficient (a) and exponent (n) were also estimated as a Key words: Burning rate, Combustion chamber, Pressure, Solid propellant, Thrust. 1.

Solid Propellant Burn Rate (Vieille's or Saint-Robert's Law) r = linear burn in/ sec P c = combustion chamber pressure n = burning rate pressure exponent a ( T )

6 Mar 2019 shelf-life, and very low-pressure exponents. They are widely used in rocket motors of tactical missiles, with the higher burning rates (e.g., over
