I hoping to look at learn more about Main Engine Cut Off (MECO) for various scenarios. 5 quantities I want are:
1) Booster mass at lift off.
2) Booster mass at MECO
3) Booster velocity at MECO (including direction, horizontal and vertical components)
4) Booster altitude at MECO.
5) Booster distance from launch pad at MECO.
The scenarios I want to compare are:
Ordinary expendable launch
Reusable booster flying a vertical path and Return To Luanch Site (RTLS)
Reusable booster flying eastward and then horizontal boost back for RTLS.
Reusable booster landing on a sea platform downrange.
It seems to me the quantities I'm looking for would vary for each scenario.
It's my belief reuse would have a hit on payload mass. I've heard vertical lofting RTLS would have a 15% hit on payload mass and horizontal boost back RTLS would have a 30% hit on payload mass. I don't know if that's accurate as I don't know what math and models are used to arrive at those figures.
