The RV-105 RCS Thruster Block is a part with four RCS thrusters used for spaceship rotation and translation movement and is fuelled by monopropellant.

Usage

This RCS thruster allows thrusting in any direction sideways to it. Placing four thrusters of this kind is sufficient to rotate and translate the craft in all directions, but then are only good for one them. In this layout the translation force along the roll axis is twice as high as the two other axes usually.

Description

The recent discovery of a third law of physics made it possible for STEADLER Corps engineers to produce these small monopropellant thrusters, to help with attitude control and linear motion. Even though many Kerbal physicists still dispute the validity of this new law, studies show that the thrusters seem to work as advertised.

STEADLER Engineering Corps

The third law of physics referenced in the quote is likely a reference to third law of motion, which says that every force generates an equal counter-force. That's exactly how monopropellant thrusters or rather any kind of reaction engines work: When expelling propellant with a specific force, an equal force pushes the spacecraft in the opposite direction.

Trivia

Between their introduction in 0.11 and 0.17.1 (including the old 0.13.3 demo), all RCS blocks were massless and dragless, despite the CFG file values. Since 0.18 (including the new 0.18.3 demo), RCS blocks have the expected mass values.

Changes

0.18.2
  • Nominal performance increased, bug providing vastly superior linear performance removed.
0.18
  • Retextured, given Isp values and actual mass.
0.11.0
  • Initial Release
