hyperloop.Python.pod.cycle.comp_len module

class hyperloop.Python.pod.cycle.comp_len.CompressorLen[source]

Bases: openmdao.core.component.Component

The CompressorMass class represents a compressor length component in an OpenMDAO model.

A CompressorMass models length of a compressor that uses NPSS data to obtain enthalpy data,and mass_flow for a particular pressure ratio. It also uses a correlation derived by Micheal Tong at NASA Glenn Center to obtain Compressor Length.

Params:

h_in : float

Heat in. (kJ/kg)

h_out : float

Heat out. (kJ/kg)

comp_inletArea : float

Compressor Inlet Area. (m**2)

h_stage : float

enthalpy added per stage. (kJ/kg)
Returns:

comp_len : float

Length of Compressor (m)
