Hi Guys,
i'm trying to build a big SSTO to travel to far away planets, moons, asteroids and so on... My goal is to go far, do many things and come back safely (as everybody wants :D).
I have some background to launch small ssto to orbit around kerbin and it's moons but only with small ships (ie no payload or very few). I achieve this with many fly test and adjustments and "by chance" my ships were finally created.
Now getting things bigger chance is no more working and my tests flys are just crash test with no learning at all...... So i beg help to experienced engineers !
My goal is :
- 20-30t of payload
- 1 crew
- 1 passager cabin
- a ramp to deliver some payload
Here is my actual design, almost working... With this I can go up to ~40km, but no more, i ran out of oxydizer for RAPIER.
Here is my fly plan that i try to stick
Full throttle
10° pitch and getting to 10Km hight
try to keep altitude around 10km and wait until Mach 4/4.5 (usually i achieve this speed while i am around 20km)
change pitch to 30-45°
rapid ascent to 26km
change rapier to closeCycle
try to keep my pitch and heading after (30km it's very hard) and plane is almost uncontrollable
40km.... oxydizer depletion... Get back to kerbin
What I have to to IMOO there are main objective :
- set my plan to lighter weight
- how to set it more manoeuvrable after 30km
Some more info about the ship :
mass : 192 000/377 000
liquidFuel : 38500 units
oxydizer : 9000 units
monopro : 1000 units
