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
| Field | Meaning and default | Range |
|---|---|---|
isp | Specific impulse; exhaust velocity is 9.81 \times ISP, which sets propellant cost. | \texttt{i32} |
thrust | Thrust in newtons, used for lift-off and landing delta-v; read as a 32-bit integer. | \texttt{i64} |
Example
