Detailed Description

Newtonian aerodynamic model.

This uses 4 matrices per surface. The organization of the data file is m Number of models [ x;y;z ] Rotation axis of model [ x;y;z ] Location of model with respect to the refernce [ v ] nx3 points [ f ] mx3 faces If the rotation axis is [0;0;0] then the model is assumed not to rotate relative to the core body.

Member Function Documentation

◆ initialize()

void aero_newtonian::initialize ( char * filename )

Initialize with a filename.

Initialize the model from an ASCII text data file.

References polygon_props(), sc_log(), and sc_warn().

◆ update()

void aero_newtonian::update	(	const ml_matrix &	u,
		const ml_matrix &	center_of_mass,
		double	rho,
		const ml_matrix &	angle
	)

Update the values of torque and force.

Compute the force and torque.

Parameters

u	Velocity vector in the ECI frame
center_of_mass	Center of mass
rho	Atmospheric density
angle	Actuator angles
