Description

The BAK-9801 Cherub is the little sister of the BAK-9900 Seraph. She is not recoverable, but is much lighter, easier to fly, and quicker to reach orbit.

Vital statistics

Launch altitude: 28-30 km
Time to launch altitude: 26-27 minutes
Take-off mass: 20-25 tons (supplied configuration: 21.8 tons)

Operation

SAS on, surface radial out. Engage rotors and fuel cells (action 1). Increase collective to 4.0 (action 3). Increase throttle until take-off. Monitor RPM to keep them under 140, gradually increasing pitch to 11.0 (action 5) while increasing throttle to match. At 3.5 km, full throttle. Allow the craft to climb to 26 km, then decrease collective to 9.0. Monitor the small fuel tank in the first stage. When it runs out, stage the launcher, commencing gravity turn around 100 m/s, and fly to orbit.

The supplied configuration reached orbit with 631 m/s in the tank, so there is a quite a lot of room for a bigger payload.
