The '''Vernor Engine''' is the first stock [[RCS]] thruster fueled by [[liquid fuel]] and [[oxidizer]] like rocket engines. Instead of being [[throttle|throttleable]] like other stock [[reaction engine]]s, the Vernor Engine reacts to movement commands for [[Reaction Control System]].

The Vernor Engine (officially known as the VR-N1ER Veer-Governor in the product description) is a RCS thruster used for craft rotation and translation. Unlike other RCS thrusters, it is fueled by liquid fuel and oxidizer.

Product description

The VR-N1ER Veer-Governor, or "Vernor" Engine is an attitude control thruster. These motors are linked to RCS controls, but are powered by a Fuel+Oxidizer mix, making them significantly more powerful than MonoPropellant-powered RCS thrusters. They are fairly more bulky in comparison though, and feature only one nozzle facing outwards, although most agree that is an acceptable trade-off for the additional punch they pack.

Usage

Compared to the other two RCS engines previously available, this new engine has a higher specific impulse in atmosphere which makes them suitable to steer heavy craft while ascending. The thrust is also 12 times higher than one RCS port which allows only a few thrusters to stabilize the craft. Because it uses liquid fuel and oxidizer the same fuel flow logic applies. Thus the part needs to be connected to a tank either directly or by a fuel transferring part.

Although it uses a different fuel, the Vernor Engine acts identically to monopropellant-based RCS ports, like the Place-Anywhere 7 Linear RCS Port.

Despite the listed mass, the part has the "PhysicsSignificance = 1" flag, making it a physicsless part; its mass and drag are added to the part it is mounted on.

Trivia

  • The name seems to be a play on Vernier thruster which are used in real life like this part to control the craft.
  • The vernor engine generates 12 Kn of thrust, which can be considered an intermidiate between the Spider and the Twitch, however, the Twitch has a TWR of 2, while the Vector's TWR is at 1.1, but, considering its ability to translate and backfire, it can be useful for small probes that have to maneuver accurately (i.e to grab onto an Asteroid)
