Unsteady Internal Ballistics of a Hybrid Rocket
<p>With the recent progress made in the field of space tourism, hybrid rocket engines have gained a renewed interest due to their simplicity, low cost, operational flexibility, and safety. The flow in the ports of a hybrid rocket motor involves several coupled unsteady phenomena like moving walls, …

Computational interior ballistics modeling
Interior ballistics are the events in a gun system that determines the performance of any gun design. In order to efficiently design any gun system the internal ballistics should be understood to minimize energy losses and correctly define design parameters. The goal of this computational model is …

Analysis of a Hybrid Rocket Burn Using Generalized Compressible Flow
… into equivalent square ports. As an example, the internal ballistics of a hybrid rocket with circular ports is analyzed by transforming it to an equivalent solid grain with square ports having the same amount of solid fuel and burn time. The results obtained are similar to that of circular port …

Optimal Sizing and Control of Hybrid Rocket Vehicles
… of the rocket. First, an analysis of the internal ballistics and the ascent trajectory has been carried out for different mass flow rates of the oxidizer as a function of time, for a fixed amount of oxidizer, in order to study the effect of throttling. Two equivalent problems are …

Performance of the UBC two-stage light-gas gun
… with systems used by other researchers. The internal ballistics of the gun were modelled with a 1½ dimension Arbitrary Lagrange Eulerian computer code. The calculations had limited success in obtaining the measured projectile velocity. The calculations were also used to estimate the time …
