Presentation Transcript

  1. FLIGHT CONTROL SYSTEMS

  2. Flight Control Systems (FCS) Control surfaces and Engine controls. Cockpit controls – Primary and Secondary. Basic FCS – Mechanical, Hydro-mechanical, Fly-by-Wire (FBW), Fly-by-Light (FBL), and IFCS. Mechanical FCS Hydro-mechanical FCS

  3. FBW Flight Control System Basic components of a FBW flight control system

  4. FBW Flight Control System – Features Electrical data transmission / serial digital data transmission with TDM. Flight control system bus configuration

  5. FBW Flight Control System – Features Failure survival control surface actuation. Quadruplex actuation system

  6. FBW Flight Control System – Features Air data information and motion sensors feedback. FBW system schematic

  7. FBW Flight Control System – Advantages Increased performance. Reduced weight. FBW control sticks. (Inceptor) Carefree maneuvering. Ability to integrate additional controls. Ease of integration of autopilot. Closed loop maneuver command control.

  8. FBW Flight Control System – Advantages Roll rate command system Roll rate response

  9. Fly-by-Light (FBL) Flight Control System Need for a protection from electro-magnetic interference (EMI). Optical transmission media – best choice. Now, the use of fibre optic links to interconnect the basic elements of the flight control system – pilot’s stick, sensors, flight control computers, actuator control electronics, etc.  Fly-by-Light.

  10. Fly-by-Light Flight Control System Passive optical sensor concept
