Constant_Temperature#

class Constant_Temperature(*args, **kwarg)[source]#

Bases: Atmosphere

Modified US Standard Atmosphere 1976 model with constant temperature profile.

This class implements a simplified atmospheric model where temperature remains constant across all altitudes while maintaining US Standard 1976 pressure and density variations.

Notes

This model is useful for simplified analyses where temperature variations with altitude are not critical, while still maintaining realistic pressure and density gradients.

Major Assumptions

  • Temperature remains constant at 301.15 K across all altitudes

  • Pressure and density variations follow US Standard 1976 model

  • Valid from -2 km to 84.852 km geopotential altitude
