Question relates to this topic Horizontal space launch
Question is rewritten, so some details are probably lost.
Here I make a sketch of the launch principle and I want to know, if it could improve the whole launch process regarding its safety in first place. In other words, I suppose that this method should reduce the probability of a fault by a launch.
This is a possible carrier, which should be reusable in ideal case. The rocket is placed on the top and splits off at certain height:
A ramp is ca 30 degrees on its end. This looks realistic, since more inclination means more construction complexity and thus safety. After liftoff it should smoothly correct it's trajectory to more vertical position, but that is not a must, it depends on how much fuel I can save due to total air resistance difference:
Whole trajectory could be like that:
Rocket detachement happens when it is time to make the trajectory more horizontal again, lets say at 10 km altitude.
Mass of the vehicle I suppose should be also optimised, it should not be too big. The carrier should land after split off, how exactly, I don't know, it is subject to a separate question.
So main questions:
This seems a much more intuitive and natural way to launch a heavy thing to the orbit. So I wonder, is vertical start believed to be safer or just some economical aspects?
What can be a strong argument against my scheme, besides fuel consumption?
- What could go wrong by rocket detachement on high speed? Like for example a strong trajectory declination due to turbulence?
Please note, this all is to a known grade just a speculation, since I am not expert and do not know specific parameters. Also it is not focused on fuel consumption aspects in first place.
Main benefit as I see it, we don't need a huge engine on first stage, which I believe is unnecessarily powerful.
Also the vehicle by vertical start does not seem to be much controllable, if at all. Small crack on the nozzle edge - and it will loose stability. Mechanical vibrations in engine area, overheating, it all adds scepticism. Looks so freaking dangerous even compared to jet fighter take off from an aircraft carrier.
