• Great progress for revamping fall onboarding, more work still needed to change slides and finalize the plans.
• Igniter redesign in progress, need to do some more research and work on both the mount and switchbox before doing a second test early fall.

• Alex did inital calculations for making the Romulus testing manifold for a water test without the nozzle
• John finished first onboarding lesson
  
  

The idea is to have a manifold with an inlet port that routes the fuel/water to the anulus without having the nozzle so we can see the impingement of the fluids. To accomplish this we can have a volume with a decreasing area as a function of the angle around the circle. This is needed to preserve the fluid velocity so the fluid around circle is uniformly ejected. As mass flow decreases, so does the velocity; we compensate for this by decreasing the cross sectional area. It will not be a linear function, but we might be able to approximate with a linear cut for machining purposes.
