Standard Atmospheres

Compute FlowState properties in standard atmospheres.

mcycle.library.standard_atmospheres.isa(double altitude, double pStag=101325., double TStag=288.15, double g=9.80665, double R=287.058, unicode fluidCP=u'Air', int phaseCP=-1) → FlowState

FlowState: Returns FlowState at desired altitude in the International Standard Atmosphere.

Parameters:

altitude : float

Geopotential altitude [m].

pStag : float, optional

Stagnation (absolute) pressure at sea level [Pa]. Defaults to 101325.

TStag : float, optional

Stagnation (absolute) temperature at sea level [Pa]. Defaults to 101325.

g : float, optional

Acceleration due to gravity [m/s^2]. Assumed to be constant. Defaults to 9.80665.

R : float, optional

Specific gas constant of air [J/Kg/K]. Assumed to be constant, air is assumed to be dry. Defaults to 287.058.
