Abstract

This article shows in a general way the optimization process for a solid fuel engine based on a mixture of Potassium Nitrate and Sorbitol (KNSB) with a Bates type grain configuration, generally used in low power experimental rocketry. In this process, the maximum thrust is selected for the least amount of mass required, indicating the estimated size of the most efficient motor through multiple iterations, where from the initial range of thrust values the amount of propellant mass required is calculated. Additionally, through the graphical estimation of the second derivative of the thrust relation to the mass, an efficiency limit is established where the increase of the propellant amount must represent at least an increase greater than 0.5% in the slope of that relationship. Finally, a model of the motor assembly schematized by computer aided design software is proposed.
