Pulse Jet

A pulse jet build with two friends, focused on making the test setup repeatable before worrying about making it fast. The goal right now is a fixture geometry that can be modified without rebuilding the whole test rig, and a data capture setup that gives comparable run-to-run numbers.

Build a pulse jet test setup where geometry changes can be evaluated without rebuilding the fixture every time. Repeatability before optimization.

• Thermal stress and material fatigue under repeated combustion runs
• Strict test safety envelope in a compact fixture format
• Currently in safety review phase. No hot fires until the protocol is signed off.

• Modular chamber and intake geometry for faster revision cycles
• Fixed ignition routing to separate ignition variables from geometry variables
• Temperature and thrust measurement integrated at set reference points before the first run

1. 01

   Initial chamber fabrication and support fixture complete

2. 02

   Safety documentation and review in progress

3. 03

   Instrumentation mounting designed into the fixture, not added after

• Fixture stiffness matters more than expected. Run-to-run geometry drift contaminated early data.
