Detailed Description

Function Documentation

AddExcrescence()

void AddExcrescence	(	const string &in	excresName,
		const int &in	excresType,
		const double &in	excresVal
	)

Add an Excresence to the Parasite Drag Tool

EXCRES_TYPE

Parameters

[in]	excresName	Name of the Excressence
[in]	excresType	Excressence type enum (i.e. EXCRESCENCE_PERCENT_GEOM)
[in]	excresVal	Excressence value

CalcAtmosphere()

void CalcAtmosphere	(	const double &in	alt,
		const double &in	delta_temp,
		const int &in	atmos_type,
		double &out	temp,
		double &out	pres,
		double &out	pres_ratio,
		double &out	rho_ratio
	)

Calculate the atmospheric properties determined by a specified model at input altitude and temperature deviation. This function may not be used for any manual atmospheric model types (i.e. ATMOS_TYPE_MANUAL_P_T).

WriteAtmosphereCSVFile()

void WriteAtmosphereCSVFile	(	const string &in	file_name,
		const int &in	atmos_type
	)
