Concept

Pulse Jets are a relatively simple machine that consists of three parts, The Intake, Combustion Chamber, and Exhaust. Working in unison to produce pulses of thrust.

There are many different configurations for a pulse jet, some of the more Iconic ones include:

• A straight inline configuration with valves such as the one used in the infamous V1 bomb

• Focused Wave "Chinese design" Pulse Jets which include an intake connected to the combustion chamber but is facing the same direction as the exhaust but offset

• The Lockwood Pulse Jet a valveless design with an iconic U shape.

The Pulse jet chosen for this project is the lockwood design. It was chosen for its ease of manufacturing, scale-ability, and it has a large amount of enthusiast use, leading to a lot of information on its design and manufacture

Put simply, the Pulse Jet functions on a pulsing repetition of explosions to produce thrust.

1. Propane fills the combustion chamber and explodes

2. A portion of the explosion goes out the intake and part of the way out of the exhaust

3. A vacuum created by the escaping gasses draws in fresh air through the intake and mixes with new propane

4. The same vacuum pulls in some of the hot gas back through the exhaust igniting the propane- air mixture now in the combustion chamber

5. the process repeats

Knowing that the Lockwood Pulse Jet is semi-scalable, finding a design with a lot of dimensions would make manufacturing easier. So the design below was chosen
