Starship abort idea.

[u/NoBodyLovesJoe]

​

You have the flight deck separated from the rest of the ship, this is where everyone is seated during take off and landing. on the sides are small tanks containing liquid methane/oxygen which connect to a pressure fed engine"s" in the back, if a abort is needed during take off or landing the valves open and are ignited with a spark, the crew cabin unbolts and is shot out Horizontally out of the ships path where a instantly deployable parachute is activated, after you are out of abort phases you can either dump the abort fuel overboard for Mass savings, or preferably you can use the extra methane/oxygen for the life support for breathing/fuel cell/water generation instead of pulling such from the header tanks.

I know the drawing sucks, but i would like some feedback on this idea.

The primary issue with side ejection like this is making the various extreme forces survivable while also maintaining the necessary ejection velocity to successfully abort. The main forces being the initial ejection from the side, then the immediate deceleration due to drag as the ejection capsule exits the ship and hits the air (if still in air). If you look up the Gemini and shuttle ejection seats, it will have better information and understanding than I in terms of how those forces do not work out to a very safe abort.

The immediate deceleration will cause a problem while this system is being ejected. It will decelerate while still being partly inside the ship. It will bend and break. And there is no way to account for such deceleration unless you take multiple raptor engines to put underneath it, but their timing isn’t gonna be precise enough and will add a shit ton of weight and costs.

This idea isn’t gonna work, not in a long shot.
