An Eight-Parameter Function for Simulating Model Rocket Engine Thrust Curves
Dooling, Thomas A.
Physics Teacher, v45 n5 p280-283 May 2007
The toy model rocket is used extensively as an example of a realistic physical system. Teachers from grade school to the university level use them. Many teachers and students write computer programs to investigate rocket physics since the problem involves nonlinear functions related to air resistance and mass loss. This paper describes a nonlinear eight-parameter function that correctly models the thrust profile for model rocket engines. Examples are given for commonly used Estes rocket engines.
