fr.cnes.sirius.patrius.assembly.vehicle.AerodynamicProperties

public class AerodynamicProperties
extends Object

This class defines an aerodynamic property to be applyied to aerodynamic parts of a vehicle (PATRIUS assembly). It has a dual nature, actually it is either an AeroGlobalProperty or an AeroSphereProperty depending on the constructor used.

Method Detail

setAerodynamicProperties

public void setAerodynamicProperties(AssemblyBuilder builder,
                                     String mainPartName,
                                     double multiplicativeFactor)

Set aerodynamic property to a part (it modifies vehicle surface model as a function of the multplicative factor).

Parameters:

builder - assembly builder

mainPartName - main part name

multiplicativeFactor - the multiplicative factor (applied to the reference surface)

getFunctionType

public AerodynamicCoefficientType getFunctionType()
                                           throws PatriusException

Get the type of the aerodynamic coefficients functions among:
- Coefficients as a function of altitude,
- Coefficients as a function of angle of attack
- Coefficients as a function of Mach number
- Coefficients as a function of Mach number and angle of attack.

Returns:

the type of function (see AerodynamicCoefficientType enumeration)

Throws:
