KerbalX

EveBlowfly

Cost: ~171k overall
Recovery: ~31k
Payload: 5 Kerbals

Rationale:

• SSTO - on Kerbin ;)
• Can’t make the Eve SSTOs work?
• Are you a shitty pilot?
• Just like me?
• This Eve ascending vehicle shall be fool-proof!
• Even I can fly it!

EveBlowfly procedures:

Take-Off (Kerbin):

• <2> to disengage rotors and close their bays
• Wait until all bumping and jumping is over
• <T> to activate SAS, <Y> for full throttle
• <3> to activate two of the Vectors
• At 100m/s pull up to 40° AoA
• Retract landing gear <G>
• Start observing apoapsis
• When it reaches 80km, put SAS on prograde, turn off Vectors <3> and thrust <X>
• Create maneuver node to circularize orbit in AP
• Execute maneuver node on single Vector <4>

Transfer to Eve:

• <0> to open small service bay
• <9> to inflate airlock
• Rendevouz with a transfer stage of your choice - I would use Pusher 3

Landing (Eve)

• Activate cooler <7>, close all bays, antenna, airlock, …
• Activate brakes, extend landing gear
• Either refuel completely before and brake by 1000m/s on Vectors …
• or burn 500m/s retrograde on Vectors
• Try coming in radial-out and bottom first
• If craft becomes uncontrollable, pump fuel in front of the rotors
• Activate rotor engines below 10km <1>, using
  • deactivate the brakes <B>
  • full thrust <Y> and
  • approximately a deploy angle of -70 on the rotors <H>/<N>
• Safe landing speed is ~50m/s
• Brakes are effective!
• Do not forget to disengage rotors! <2>

Hints for Eve

• Transfer flights on Eve using the rotors may need you to use reserve fuel <6>
• Refuel using some ground station
• With the small service bay open <0>, <8> helps you getting Kerbals onboard

Take-Off (Eve)

• Disable side-to-mid cross feed <5>
• Activate cooler <7>, close all bays, antenna, airlock, …
• <1> to engage rotors and open the bays
• Open and fix stats of one rotor and one fan blade
• <B> loosen the brakes
• Put engines on full power <Y> and adjust rotors as needed <H>/<N>
• -68 fan blade deploy angle and 80m/s shoud be fine for take-off
• Climb to 12500m and try to go as fast as possible, maybe 130m/s
• Turn off rotors <2> and activate side vectors <3>
• Pull up to an AoA of 30-40°
• Stage <space> when out of fuel until middle vector is active
• Start observing apoapsis, cut off thrust <X> if it reaches 110km
• Quickly create circularization maneuver node
• Execute on Vector, stage to Terrier if needed
• Reserves should be plenty, 1900m/s left in 200x200km Eve orbit

Transfer to Kerbin:

• <0> to open small service bay
• <9> to inflate airlock
• Rendevouz with a transfer stage of your choice
• Remaining piece can nicely be landed on Kerbin docking it into the bay of a SpacePony

A stock aircraft called EveBlowfly.
Built with 118 of the finest parts, its root part is landerCabinSmall.

Built in the SPH in KSP version 1.9.1.

Acknowledgements:
No idea who invented the impellers you find in Eve planes regularly at the moment.
I found them on Mephisto’s Eve SSTO here and in that thread he linked.

But unfortunately I am to incapable to fly or even copy those masterpieces.
And I do not like heavy clipping.
So after this thing is now fool-proof, I thought I re-share it to help others as well.
