I want to see a "reverse aerospike" as the diverter.
OK so it's just a plain spike, with a water outlet at the top, dump a
squillion tonnes of water out the top of an 8ish meter high spike (to
fit under the OLM) that has a nice radiused curve into being level with
the ground.
Careful here -- the aerodynamics of flame deflectors, especially big ones,
aren't simple. That exhaust flow is highly supersonic, and when it hits
something shock waves will form, so just making the shape any old smooth
curve won't necessarily do what you want.
