Maths: tylo landing

[Lohan2008]

Craft weight: 5.26 t, Speed 2136 m/s, altitude 35-106 km, fuel: 163/200, engine lv-909

Looks like I will land too hard.... suggestions ???

Lv 909 = impact 1400 m/s Edited January 26, 2015 by Lohan2008

Suggestion = F9.

Mass and fuel-units not imporant on their own (included in dV and TWR calcs).

Can't do TWR calcs without knowing thrust.

Can't do dV calcs without knowing engine Isp.

ETA for post #3 above: burn to circularise instead of landing. Rescue later

Nevermind. Unless you happen to have an LV-N, there's no way you're making that landing.

Nowhere near enough DV.

My advice is to abort the landing and figure out how to get more fuel on board. You need an absolute minimum of 2,270 m/sec to land on Tylo.

Best,

Also, for future reference, you're gonna want a lot more thrust for a better TWR on future landing attempts. For ~ 5 tons, you'd probably want at least 100 kN of thrust to get of Tylo's surface (TWR ~ 2.5), which would be at least 2 909s.
