[RSS] LCUS/Sail Block-A Upper Stage

General Introduction:

LCUS, or LPE Cryogenic Upper Stage

Sail Block-A, the first upper stage of LCUS, uses liquid hydrogen and liquid oxygen as fuel, using IVF technology to make better use of the leaked liquid hydrogen.

The engine uses a modified FE-10A closed expansion cycle hydrogen-oxygen engine from ATGA.

Thanks to SatelliteTorifune for guidance and assistance in engine programming.

Liquid hydrogen tank diameter: 5.2m

Liquid oxygen tank diameter: 3.5m

Introduction to Activation group:

AG 10: IVF RCS

How to use:

Start each component by activating the next tier.

A stage is activated after the separation/sinking engine is ignited and the engine is started by changing the throttle valve.

Throttle range: 5%~100%, when the throttle is less than or equal to 5%, it automatically enters the engine shutdown procedure.

Hope you have a good time!
