ABSTRACT

This engineering reports the design construction and analysis of a pulsejet engine to achieve

static thrust. An engine was designed using available theory. Following a delay due to ignition

system problems, the completed engine was tested extensively in an attempt to achieve static

thrust. Various sizes of pulsejets are used to study the effects of heavy liquid fuels like

kerosene and military grade JP-8. A pulsejet According to the design is constructed, is used

with gasoline to verify data acquisition techniques, and attempts are made to use LPG to fuel

the jet to prove the viability of using LPG to power pulsejet engines. A large valved pulsejet,

predicted to deliver 21 lbs of thrust, is designed to be used with LPG for initial testing to prove

the feasibility of using such a propulsion device for personal troop transport. A 25 cm valveless

pulsejet is designed, fabricated, and tested using LPG to determine if such an engine is practical

for propelling a small, high speed Unmanned Aerial Vehicle (UAV) for military application.

Dimensions are calculated by using thrust by Theoretical calculations .
