  • Type: SPH
  • Class: spaceplane
  • Part Count: 139
  • Mods: 5 ###Description A large, SSTO test vehicle for large payloads.

A mod aircraft called XSP1 Ostritch. Built with 139 of the finest parts, its root part is HL.Aero.Cockpit. It has a large cargo bay, and is a great LKO payload delivery platform.

Flight instructions:

To enter orbit -

• Apply brakes, fire engine to maximum thrust, then release the brakes. • Nose up occurs at about 90-120 m/s, depending on payload. • Pitch up 20 degrees through 12km. • At 12km alt., level pitch to between 10-15 degrees, keeping velocity vector rising at all times. • Build velocity to around 1,500-1,700 m/s. • At around 35km alt., SABRE-M engines will toggle to rocket mode. • At engine toggle, pitch up to 45 degrees and push apoapsis to desired altitude. • Once apoapsis is reached, set orbital insertion burn node. You will likely still be rising through upper atmosphere at this point. • IF USING NEAR/FAR - With engines cut, fine tune apoapsis up or down as you rise through upper atmosphere by adjusting nose pitch above or below velocity vector

My De-Orbit Procedure (NEAR, Deadly re-entry) –

• Establish new equatorial orbit circularized at 75km alt. • Set 200m/s DV retro burn ¾ of an orbit away from KSC • Immediately re-align along prograde vector. • Double check center of lift & mass to make sure craft aerodynamically stable. (Note: Lights on cargo bay floor mark the center of lift for craft. In-flight POV rotates around center of mass. Make sure POV focal point is slightly ahead of cargo bay floor lights to ensure craft aerodynamically stable. If not, pump fuel to adjust COM. Tanks are located fore and aft.) • Descend through atmosphere at pitch .0 degrees, heading 90 degrees. • Glide to runway.

Built in the SPH in KSP version 0.90.0.
