Questions for future iterations:
- What is a good momentum ratio for Nitrous/IPA?
- Will the top of the chamber wall melt if it's being sprayed by nitrous exiting radially out of the pintle tip?What is the optimal skip length (distance from annulus exit to pintle tip exit)/a rule of thumb for the skip length? How will we enforce that length if we're screwing the pintle tip in?
- For some pintles, I've seen the bottom face of the baseplate be slanted – is there any advantage to this? Perhaps if the taper is parallel to the spray angle it will prevent hotspot accumulation on the sides?
- Does combustion happen right at the face of the pintle tip, where the two fluids collide? If it does, is it a concern?
- How will pressure of the nitrous manifold be measured? Is it okay to just have a PT right before the nitrous flows into the center body?
