Method Summary

Modifier and Type	Method and Description
void	checkConfiguration(SolidRocketMotor solidRocketMotor)
double	getBurningArea(double burnProgression) Compute the burning area during burn
double	getGrainEndSurface(double burnProgression) Compute the end grain surface during burn
double	getGrainVolume(double burnProgression) Compute the grain volume during burn
double	getXincp(int numberOfPoints) This method should return the length that will be remove in each computation iteration ex : for hollow cylinder grain this will be : initial web thickness / numberOfPoints

Method Detail

getGrainEndSurface

double getGrainEndSurface(double burnProgression)

Compute the end grain surface during burn

Parameters:

burnProgression - (0 to 1, 0 = before burn start ; 1 = grain completly burn)

Returns:

the end grain surface in mm^2

getGrainVolume

double getGrainVolume(double burnProgression)

Compute the grain volume during burn

Parameters:

burnProgression - (0 to 1, 0 = before burn start ; 1 = grain completly burn)

Returns:

the grain volume in mm^3

getBurningArea

double getBurningArea(double burnProgression)

Compute the burning area during burn

Parameters:

burnProgression - (0 to 1, 0 = before burn start ; 1 = grain completly burn)

Returns:

the burning area mm^2

getXincp

double getXincp(int numberOfPoints)

This method should return the length that will be remove in each computation iteration ex : for hollow cylinder grain this will be : initial web thickness / numberOfPoints

Parameters:

numberOfPoints - the number of iteration during the computation

Returns:

xincp (cf. SRM_2014.xls)

checkConfiguration

void checkConfiguration(SolidRocketMotor solidRocketMotor)
                 throws InvalidMotorDesignException

Throws:
