Calculation of Solid Fuel Rockets Optimal Values by Analytical Method
Ján Tvarožek, Július Alcnauer

Abstract
This article deals with the analytical method of solid fuel rocket calculating. Reference is made to methodology of determining mathematical functions, which have great importance for calculation not these rockets. In the article, as an example of use of analytical method, characteristic numbers dependencies on length of solid fuel grain and caliber of rockets (diameter of combustion chamber) are derived. Using these dependencies’ (functions), and some analytical operations with them, it Is possible to determine main parameters of the rocket, and their optimal values.
