Typically, there are annular ports on the injector plate to introduce fuel to cool the combustion chamber. Why is LOx not used for cooling despite it being extremely cold?
Given there will be a lot of LOx droplets on the inside, will it also impinge and provide additional cooling or the combustion chamber design takes care none of the LOx droplet come in contact with the chamber wall?
Cons of cryogenic LOx are:
- might cause thermal shocks on the wall
- oxidation/corrosion of chamber wall
This might end up damaging the chamber.
