USStandardAtmosphere1976 Class

Provides scalars that calculate values using the U.S. Standard Atmosphere model, 1976 version. This model is defined with respect to mean sea level, so you must configure the MeanSeaLevel property on EarthCentralBody before using this model.

Properties

	Name	Description
	Density	Gets a ScalarDependentOnServiceProvider that calculates atmospheric density using the U.S. Standard Atmosphere model, 1976 version, in kg/m^3. The calculation requires the given service provider to provide the ILocationPointService service.
	DensityRatio	Gets a ScalarDependentOnServiceProvider that calculates the ratio of the local density to the density at sea level using the U.S. Standard Atmosphere model, 1976 version. The calculation requires the given service provider to provide the ILocationPointService service.
	EarthRadius	Gets or sets the effective radius of the Earth (r₀) used by the model, in meters. By default, this value is 6356766.0.
	EarthSurfaceGravity	Gets or sets the sea-level value of the acceleration of gravity (g₀) used by the model, in m/s^2. By default, this value is 9.80665.
	IdealGasConstant	Gets or sets the ideal gas constant (R^) used by the model, in J/(kmolK). By default, this value is 8314.32.
	IsFrozen	Gets a value indicating whether this object is frozen. A frozen object cannot be modified and an ObjectFrozenException will be thrown if an attempt is made to do so. (Inherited from DefinitionalObject.)
	MeanMolecularWeightAtSeaLevel	Gets or sets the mean molecular weight of the atmosphere at sea level (M₀) used by the model, in kg/kmol. By default, this value is 28.9644.
	Pressure	Gets a ScalarDependentOnServiceProvider that calculates atmospheric pressure using the U.S. Standard Atmosphere model, 1976 version, in pascals. The calculation requires the given service provider to provide the ILocationPointService service.
	SpecificHeatRatio	Gets or sets the ratio of specific heat of air at constant pressure to the specific heat of air at constant volume used by the model (γ). By default this value is 1.4.
	SpeedOfSound	Gets a ScalarDependentOnServiceProvider that calculates the speed of sound using the U.S. Standard Atmosphere model, 1976 version, in m/s. The calculation requires the given service provider to provide the ILocationPointService service.
	Temperature	Gets a ScalarDependentOnServiceProvider that calculates temperature using the U.S. Standard Atmosphere model, 1976 version, in kelvin. The calculation requires the given service provider to provide the ILocationPointService service.

Methods

	Name	Description
	Calculate	Calculate results from the U.S. Standard Atmosphere model, 1976 version.
	Clone	Clones this object using the specified context. (Overrides DefinitionalObjectClone(CopyContext).)
	EnumerateDependencies	Enumerates the dependencies of this object by calling EnumerateT(T) for each object that this object directly depends upon. Derived classes which contain additional dependencies MUST override this method, call the base implementation, and enumerate dependencies introduced by the derived class. (Inherited from DefinitionalObject.)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Freeze	Freezes this object. Further attempts to modify it will result in an ObjectFrozenException. (Inherited from DefinitionalObject.)
	GetDefinitionHashCode	Gets a hash code representing the definition of this object. (Inherited from DefinitionalObject.)
	GetEvaluator(IServiceProvider)	Gets an evaluator that can be used to calculate results from this model for a given location.
	GetEvaluator(EvaluatorGroup, IServiceProvider)	Gets an evaluator that can be used to calculate results from this model for a given location.
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IsSameDefinition	Determines if this object has the same definition as another object. (Inherited from DefinitionalObject.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
