Constant_Throttle_Constant_Speed

Functions

initialize_conditions(segment)	Sets the specified conditions which are given for the segment type.
unpack_body_angle(segment)	Unpacks and sets the proper value for body angle
update_differentials_altitude(segment)	On each iteration creates the differentials and integration funcitons from knowns about the problem.

unpack_body_angle(segment)

Unpacks and sets the proper value for body angle

Parameters:

segment (Segment) – The mission segment being analyzed

Notes

This function handles the initialization of the body angle for a climb segment with constant throttle and constant speed.

Required Segment Components

segment:

state:

unknowns:

body_anglearray

Aircraft body angle [rad]

conditions:

frames:

body:

transform_to_inertialarray

Rotation matrix from body to inertial frame

Returns:

Updates segment conditions directly: - conditions.frames.body.transform_to_inertial

Return type:

None

initialize_conditions(segment)

Sets the specified conditions which are given for the segment type.

Assumptions: Constant throttle estting, with a constant true airspeed

Source: N/A

Inputs: segment.air_speed [meters/second] segment.altitude_start [meters] segment.altitude_end [meters] segment.state.numerics.dimensionless.control_points [Unitless] conditions.freestream.density [kilograms/meter^3]

Outputs: conditions.frames.inertial.velocity_vector [meters/second]

Properties Used: N/A

update_differentials_altitude(segment)

On each iteration creates the differentials and integration funcitons from knowns about the problem. Sets the time at each point. Must return in dimensional time, with t[0] = 0

Assumptions: Constant throttle setting, with a constant true airspeed.

Source: N/A

Inputs: segment.climb_angle [radians] state.conditions.frames.inertial.velocity_vector [meter/second] segment.altitude_start [meters] segment.altitude_end [meters]

Outputs: state.conditions.frames.inertial.time [seconds] conditions.frames.inertial.position_vector [meters] conditions.freestream.altitude [meters]

Properties Used: N/A
