So I'm sure many of you on this forum have heard of ramjets, which would be ideal for supersonic travel but have one drawback - they need to be accelerated to high speeds to be made efficient.
I read that a Ramjet becomes "self sustaining" at speeds of above Mach 0.5, which got me thinking. Obviously, throwing jet engines and ramjets onto one airframe would be hideously inefficient. However, what if you accelerate the ramjet up to speed on the ground - using say, an electromagnetic catapult or steam catapult like what is used on aicraft carriers? Obviously, you would need to build new runways which have roughly double or triple the length of current runways in order to make the acceleration comparable to a normal aircraft.
Basically, what do you think of this idea? Is it commercially viable? I don't really know what to make of it and I'm curious.
