RCAIDE.Library.Mission.Segments.Climb.Linear_Speed_Constant_Rate.initialize_conditions

initialize_conditions(segment)

Initializes conditions for linear speed climb segment

Parameters:

segment (Segment) – The mission segment being analyzed

Notes

This function sets up the initial conditions for a climb segment with linearly varying airspeed and constant rate of climb. The airspeed varies linearly between the start and end values.

Required Segment Components

segment:

• climb_ratefloat

  Rate of climb [m/s]

• air_speed_startfloat

  Initial true airspeed [m/s]

• air_speed_endfloat

  Final true 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

Calculation Process

1. Discretize altitude profile

2. Calculate velocity magnitude variation

3. Decompose velocity into components using:

   • Climb rate constraint

   • Sideslip angle

   • Linear speed profile

Major Assumptions

• Linear airspeed variation

• Constant rate of climb

• Small angle approximations

• Quasi-steady flight

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
