Kinematic Model

The Kinematic Model describes the equations of motion the govern the orientation, movement and position of an aircraft. They are describe by:

McFarland, Richard E.: A Standard Kinematic Model for Flight Simulation at NASA-Ames, NASA CR-2497, January 1975

The following structure chart describes the functional calling hierarchy of the kinematic model code. Ls_toplevel_init() is called to initialize the system, and ls_update() is called during each iteration.

There are four control inputs set within crrc_main.c, and then copied into four corresponding variables used within the kinematic model code.

Module Variable
crrc_main.c aileron_input elevator_input rudder_input throttle_input
ls_update() Lat_Control Long_Control Rudder_Pedal Throttle_pct

Module	Variable
crrc_main.c	aileron_input	elevator_input	rudder_input	throttle_input
ls_update()	Lat_Control	Long_Control	Rudder_Pedal	Throttle_pct
