I think this is fundamentally pretty hard problem. It involves control of turbulence, and this is a big in general unsolved problem today. That includes hypersonic flights, thermonuclear plasma control... Rocket engines work on the edge of material capabilities, and fluctuations - which you want to tame to guarantee things like that won't happen - are hard to deal with.
