Engine

Base Class: Part

Engine of a ship (vehicle/vessel).

Instance Properties:

• multiModule: MultiModeEngine - [Unsafe] KSP API. Module of multi-mode engine, if present (null otherwise).
• firstModule: ModuleEngines - [Unsafe] KSP API. Module of first engine.
• secondModule: ModuleEngines - [Unsafe] KSP API. Module of second engine, if present (null otherwise).
• firstIsActive: bool - Running primary engine (or the only one).
• secondIsActive: bool - Running secondary engine.
• activeModule: ModuleEngines - [Unsafe] KSP API. Active engine module.
• gimbalModule: ModuleGimbal - [Unsafe] KSP API. Gimbal module, if present (null otherwise).
• multiMode: bool - Is multi-mode engine (or not).
• hasGimbal: bool - Has gimbal module.
• operational: bool - Whether engine is operational (ignited and not flameout).
• ignited: bool - Wheter engine is ignited.
• flameout: bool - Wheter engine flamed out.
• isp: double - Current ISP (Specific impulse). [seconds]
• vacuumIsp: double - Vacuum ISP. [seconds]
• seaLevelIsp: double - Sea-level ISP. [seconds]
• thrust: double - Current thrust [kN] (at current pressure, with current thrustPercentage and current throttle).
• thrustPercentage: double - Thrust limiter in percents.
• propellants: PropellantList - [WIP] List of propellants used by the engine (by currently active mode).
• propellants1: PropellantList - [WIP] List of propellants used by first mode.
• propellants2: PropellantList - [WIP] List of propellants used by second mode (null for single-mode engines).
• booster: bool - [WIP] Indicator that the engines is (probably) solid rocket booster (contains propellant that does not flow).

Instance Methods:

• istype(): bool, name string
  • Accepts engine. (Case insensitive)
• activate(): void - Activate the engine.
• shutdown(): void - Shutdown / deactivate the engine.
• getIsp(): double, atm double
  • Get specific impulse [kN] at atmospheric pressure (0 = vacuum, 1 = Kerbin sea-level pressure, default NaN = current pressure).
• getThrust(): double, atm double, throttle double
  • Get thrust [kN] at atmospheric pressure (0 = vacuum, 1 = Kerbin sea-level pressure, default NaN = current pressure) and throttle (default 1 = full throttle). Ignores thrustPercentage.
