Description

A mod aircraft called FAR POWERMONGER . Built with 125 of the finest parts, its root part is MK2 Cockpit.
Built in the KSP version 0.90. Test and Run with F.A.R
4 RAPIER engines powerfull spaceplane leaving you with 2100 DV to use at 100km orbit around Kerbin. Its 4 Rapiers associated with 4 individual Sabre air intakes allow a continuous climb at 50 m/s vertical speed accelerating up to 33000m and Mach 3.85 before switching on Rocket cycle. No need of vernor engines or RCS as it flies easily through hypersonic speed with only the help of Mechjeb to deal with small roll oscillations.

Flight Manual for auto flight or manual flight

TAKE OFF 49T
Switch all RAPIER on manuel switch mode
Preset Pilot assistant on Heading 90 and Vertical speed 50
Select SAS, start 4 engines and apply full power
Take off smoothly at 110 - 120 m/s, fly positive climb and retract gear
Select Heading, then Vertical speed on Pilot assistant and let your spaceplane climb on 90° and V/S 50m/s accelerating
You can time warp 3. It is very stable. Prepare a mechjeb ascent profile at 21%
Climb continuously up to 23000m keeping this parameters, you should reach M2.92 or 915m/s speed.
At 23-24000m you should encounter roll oscillations.
Switch off any Pilot assistant selections and Select Mechjeb Ascent guidance with the 21% turn shape profile, it will go easy through oscillations.
At 33000m switch on Rocket mode (action group 3 and 4) and select 25% on turn shape profile.
You will pass rapidly through last roll oscillations, then you can leave Mechjeb do the job or take it manually.
I tried different ascent profile and this one leave you 2100 DV at 100 km orbit.
When establish don’t forget to balance fuel on TAC fuel balancer

Re entry
If minimum fuel fill the forward tank as COG goes back when low fuel
The spaceplane is well strut and should go through unwanted stall or spin.
AT 40000m burn on retrograde to set speed under 1500m/s, the using SAS turn on prograde You could encounter stall and spin and you should pass through.
Preselect Heading and -150m/s vertical speed on Pilot assistant and don’t forget to leave prograde on SAS before switching PA modes When stabilize, switch 2 or 4 Rapier (action grp 3 and 4 to cycle to air cycle, then 1 and 2 to start engines) and fly on manual or using PA.
Final around 80m/s or less. At 10m on final, vertical speed 5m/s, select brakes, this will deploy chutes and speed brakes. Cut off power and you should stop very quickly. All this can be done manually or through Pilot assistant.

Landing on low gravity Use Rocko engines , they are balanced for fuel in central tanks. If necessary, Pump fuel from forward and aft tank to central tanks.

Docking on refuelling stations Docking port is a center of gravity, use RCS Thrusters
