All Rocket engines produce thrust as a result of two inputs that make up the Propellant: an Oxidizer and a Fuel.The Fuel is pretty self explanatory, it provides a source of combustion that is capable of accelerating gas. The hybrid fuel is contained within the combustion chamber, and the oxidiser is fed from an oxidiser tank. at the University of Miami. The solid fuel is built into the combustion chamber in the form of a cylinder with one or more channels hollowed out along its axis. Some of the issues with hybrid rocket motors are that they vibrate a lot and are prone to unstable combustion which makes the thrust and pressure vary during the burn. Abstract. Without a engine there is no way to get there so we had to make our own. Liquid oxygen and paraffin-based fuel are . As far as I can tell, there are no advantages to them at all. Another option could be to figure out a way to project the injector plate since the heat from the ignited fuel can damage the injector plate quite easily.

Hybrid (solid-fuel/fluid-oxidizer) rocket engines offer advantages of safety and simplicity over fluid-bipropellant (fluid-fuel/fluid-oxidizer) rocket engines, but the thrusts of HTPB-based hybrid rocket engines are limited by the low regression rates of the fuel grains. I was thinking that I could improve the geometry of the injector plate in order to help improve some issues with the hybrid rocket - such as the burn regression rate. The Oxidizer is also a very important components when it comes to any combustion reaction as stated in the equation that defines a combustion reaction. Hybrid rocket engines are classified as those that utilize a liquid oxidizer and solid propellant to achieve thrust. After a first chapter brushing up on the science and maths .

American Institute of Aeronautics and Astronautics 12700 Sunrise Valley Drive, Suite 200 Reston, VA 20191-5807 703.264.7500 When the liquid oxidiser passes through the solid fuel in a chamber, they combust to form high temperature gases, which pass through a nozzle to provide thrust. Most of the propellant combinations listed are dangerous, toxic, and expensive. A hybrid-propellant rocket is a rocket with a rocket motor that uses rocket propellants in two different phases: one solid and the other either gas or liquid.The hybrid rocket concept can be traced back to the early 1930s. Before beginning a design encompassing all parts of the rocket we decided to design and build the engine first, since it is the main component of the rocket.
