rocket

Rocket propellant stats of a fluid.

Place the object under traits in a fluid-property file. Rocket and station engines, orbital-station docking and the Rocket Transporter Pad read it; the transporter cannot send without a propellant carrying it. The LPW-3N Station Thruster accepts a heated product only when that product has this trait. An engine whose propellant lacks it uses ISP 300; station docking then uses thrust 600,000.

Fields

FieldMeaning and defaultRange
ispSpecific impulse; exhaust velocity is 9.81 \times ISP, which sets propellant cost.\texttt{i32}
thrustThrust in newtons, used for lift-off and landing delta-v; read as a 32-bit integer.\texttt{i64}

Example

From data/hbmspace/fluid_property/hydrazine.json:

{"rocket": {"isp": 210, "thrust": 600000}}
