Detailed Description

Computes the acceleration due to drag in the Earth's atmosphere for a given height and velocity.

This component is attached to the spaceship and called via the GEExternalAcceleration interface from within the physics integrator as a callback. It will potentially get called a LOT so efforts are made to make the acceleration computation effecient where possible.

Member Function Documentation

acceleration()

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

Determine the acceleration due to atmospheric resistance.

Parameters

time	(not used)
gravityState
massKg	Updated mass (0 to use the inertial mass from inspector)

Returns

Implements GEExternalAcceleration.

GetAccelSI()

double EarthAtmosphere.GetAccelSI

(

)

Get the last "in flight" value for atmosphere deceleration.

Returns

Magnitude of the acceleration in m/s^2
