Detailed Description

Uses no fuel.

Member Function Documentation

virtual bool DtNoFuelUsageAircraftFuelConsumptionModel::addDataPoints	(	const DtRwAircraftEngineEfficiencyDataPointList &	datapoints,
		double	startMass,
		double	endMass,
		std::ostream *	errorStream = `0`
	)

virtual

Configure the model with a set of data points.

Each data point has a range, altitude, and speed. Combined with the startMass and endMass, can be used to determine an engine efficiency.

Parameters

startMass	Starting mass of aircraft.
endMass	Ending mass of aircraft. For example if the aircraft starts out with a full fuel tank and uses all of it's fuel (the usual case for range specifications) then startMass would be the mass of the aircraft plus the mass of the full fuel tank and endMass would be the mass of the aircraft. This doesn't have to be the case though, if you knew the range when using half the fuel then you could use that.

virtual double DtNoFuelUsageAircraftFuelConsumptionModel::interpolateEfficiency	(	double	speed,
		double	altitude
	)		const

virtual

Interpolate an engine efficiency at a given speed and altitude.

virtual double DtNoFuelUsageAircraftFuelConsumptionModel::fuelConsumed	(	double	range,
		double	speed,
		double	altitude,
		double	mass
	)		const

virtual

Calculate the fuel consumed over a given range.

Parameters

mass	The mass of the aircraft (airframe + fuel) at the start of the movement. Does not take into account the amount of fuel the aircraft has, i.e. it may use more fuel than the aircraft has. It's up to the user to actually deal with decrementing the fuel.

virtual double DtNoFuelUsageAircraftFuelConsumptionModel::calculateRange	(	double	speed,
		double	altitude,
		double	startMass,
		double	endMass
	)		const

virtual

Calculates the range at specific conditions.

virtual bool DtNoFuelUsageAircraftFuelConsumptionModel::shouldConsumeFuel ( ) const

virtual

Always returns false.
