Accounting for Non-Constant Thrust in a Model Rocket Simulator

Model rocket simulators usually account for the thrust of the engine by assuming it is constant. However, in reality the force is not constant. The purpose of this project is to determine the thrust curves of various model rocket engines by measuring the thrust vs. time and fitting an eight-parameter function to the data. The thrust curves were used in a rocket simulator developed with Easy Java Simulations (EJS) and results were compared with the case of constant force.
