"Pulsed Jet Propulsion"
Pulse Jet Engine Project
The higher thrust generating capability of a pulse jet engine makes it very desirable in a variety of aerospace applications such as in a Vertical Take Off Landing (VTOL) aircraft. In this project, the dependence of thrust of the pulse jet engine on various operating parameters such as fuel mass flow rate, air intake, length of exhaust pipe, etc. will be studied in some detail. An empirical relation describing the relationship between these parameters will be developed.

Project Details
The project we are working on is A High Thrust Propulsion System. A high thrust propulsion system is a machine that produces thrust to push an object forward. A gas, or working fluid, is accelerated by the engine, and the reaction to this acceleration produces a force on the engine. In this project, we will study in some detail how the fuel mass flow rate, air intake, and length of exhaust pipe will affect the amount of thrust. The problem with using a high thrust propulsion system is that most aircrafts don’t require high thrust for a long period of time. Most aircrafts, like airlines and cargo planes, spend most of their life in a cruise control condition, so it is very important to understand what applications would be able to use a high thrust propulsion system. For these airplanes, excess thrust is not as important as high engine efficiency and low fuel usage. Another problem with the high thrust propulsion system is that it is not extremely marketable at this current moment in time, however, a great amount of research is being put into place for this system.

The prototype we intend to build at the moment does not have a fixed price, but it may range from $75-$150. The price depends on the size of scale we want the model to be. As a solution for the above problems, we will study and manipulate a high thrust propulsion jet engine in order to observe the change in thrust. While working with the pulse jet engine, we will hopefully observe the advantages of the high thrust capabilities produced by the pulsejet, and the fuel efficiency compared to regular engines. We will also hopefully stumble upon some complications, which will give us insight into why the pulse jet engine is not used in more aircrafts today.
