In this study, the nuts and bolts of designing and building a high powered rocket have been
presented. A computer simulation program called RockSim was used to design the rocket. Simulation
results are consistent with time variations of altitude, velocity, and acceleration obtained in the
actual flight. The actual drag coefficient was determined by using altitude back-tracking method and
found to be 0.825. Speed of the exhaust determined to be 2.5 km s −1 by analyzing the thrust curve
of the rocket. Acceleration in the coasting phase of the flight, represented by the second-degree
polynomial of a small leading coefficient, have been found to approach ‘- g ’ asymptotically.
