RCAIDE.Library.Mission.Segments.Climb.Constant_EAS_Constant_Rate

Constant_EAS_Constant_Rate

Functions

initialize_conditions(segment)

Initializes conditions for constant equivalent airspeed climb segment

initialize_conditions(segment)

Initializes conditions for constant equivalent airspeed climb segment

Parameters:

segment (Segment) – The mission segment being analyzed

Notes

This function sets up the initial conditions for a climb segment with constant equivalent airspeed (EAS) and constant rate of climb. It handles the conversion between EAS and true airspeed accounting for density variations with altitude.

Required Segment Components

segment:

• climb_ratefloat

  Rate of climb [m/s]

• equivalent_air_speedfloat

  Equivalent airspeed [m/s]

• altitude_startfloat

  Initial altitude [m]

• altitude_endfloat

  Final altitude [m]

• sideslip_anglefloat

  Aircraft sideslip angle [rad]

• state:

  numerics.dimensionless.control_pointsarray

  Discretization points [-]

  conditionsData

  State conditions container

• analyses:

  atmosphereModel

  Atmospheric model for property calculations

Conversion Process

1. Compute atmospheric properties at altitude

2. Convert EAS to true airspeed (TAS) using density ratio

3. Decompose TAS into velocity components

Major Assumptions

• Constant equivalent airspeed

• Constant rate of climb

• Standard atmosphere model

• Small angle approximations

• Incompressible flow

Returns:

Updates segment conditions directly: - conditions.frames.inertial.velocity_vector [m/s] - conditions.frames.inertial.position_vector [m] - conditions.freestream.altitude [m]

Return type:

None
