class openconcept.atmospherics.compute_atmos_props.ComputeAtmosphericProperties(**kwargs)

Bases: Group

Computes pressure, density, temperature, dyn pressure, and true airspeed

Inputs:

  • fltcond|h (float) – Altitude (vector, km)

  • fltcond|Ueas (float) – Equivalent airspeed (vector, m/s)

  • fltcond|TempIncrement (float) – Temperature increment for non-standard day (vector, degC)

Outputs:

  • fltcond|p (float) – Pressure (vector, Pa)

  • fltcond|rho (float) – Density (vector, kg/m3)

  • fltcond|T (float) – Temperature (vector, K)

  • fltcond|Utrue (float) – True airspeed (vector, m/s)

  • fltcond|q (float) – Dynamic pressure (vector, Pa)

Options:

  • num_nodes (int) – Number of analysis points to run (sets vec length) (default 1)

  • true_airspeed_in (bool) – Flip to true if input vector is Utrue, not Ueas. If this is true, fltcond|Utrue will be an input and fltcond|Ueas will be an output.
