override void	SetThrottlePercent (float throttlePercent)
	Set the engine throttle level (as a percent).
override void	SetEngine (bool on)
	Set engine state to on.
override double[]	acceleration (double time, GravityState gravityState, ref double massKg)
	Determine the acceleration at the specified time. The accleration returned must be in the physical units used by the integrators. For GE units other than DIMENSIONLESS this will involve some use of GravityScalar conversion functions. See the MultiStageEngine implementation for an example.

Member Function Documentation

acceleration()

override double[] OneStageEngine.acceleration ( double  time, GravityState  gravityState, ref double  massKg  )

virtual

Determine the acceleration at the specified time. The accleration returned must be in the physical units used by the integrators. For GE units other than DIMENSIONLESS this will involve some use of GravityScalar conversion functions. See the MultiStageEngine implementation for an example.

When used in trajectory mode, this function may be called more than once for a given time, and as thrust changes. It will also be called for future times to determine the future path of the rocket.

Parameters

time	time for which the thrust should be determined.

Returns

acceleration in [0..2], mass in [3]

Implements RocketEngine.

GetFuel()

override float OneStageEngine.GetFuel ( )

virtual

Get the current fuel remaining.

Returns

Amount of fuel in the current stage

Implements RocketEngine.

GetThrottlePercent()

override float OneStageEngine.GetThrottlePercent ( )

virtual

Implements RocketEngine.

SetEngine()

override void OneStageEngine.SetEngine ( bool  state )

virtual

Set engine state to on.

Parameters

state

Implements RocketEngine.

SetThrottlePercent()

override void OneStageEngine.SetThrottlePercent ( float  throttle )

virtual

Set the engine throttle level (as a percent).

Parameters

throttle

Implements RocketEngine.

SetThrustAxis()

override void OneStageEngine.SetThrustAxis ( Vector3  thrustAxis )

virtual

Set the thrust axis. May be over-ridden to update internals if they exist.

Parameters

thrustAxis

Implements RocketEngine.
