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 fixture geometry that can be modified without rebuilding the whole test rig, plus instrumentation that will make later test data comparable.

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

   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 needs to be measured before hot-fire testing. If the fixture moves under load, geometry changes will be impossible to evaluate cleanly.
