  1. ELEMENT OF AERONAUTICS 111305

  2. PARTS OF AEROPLANE THE IMPORTANT PARTS OF AN AROPLANE • WINGS • FUSELAGE • EMPENNAGE • LANDING GEARS • CONTROL SURFACE • ENGINES

  3. PARTS OF AEROPLANE

  4. AIRCRAFT : CLASSIFICATION AND PARTS 1. CLASSIFICATION BY CONFIGURATION • POSITION OF THE WING • LOW WING • MID WING • HIGH WING • NUMBER OF WINGS • MONO PLANE • BI PLANE • TRI PLANE • SHAPE OF THE WINGS • DELTA WING • DIAMOND WING • SWEPT WING • GULL SHAPED WING • POSITION OF THE WINGS • CONVENTIONAL WING • NO TAIL OR TAILESS • HORIZONTAL TAIL LOCATED AOVE THE VERTICAL TAIL • CANARD TYPE

  5. AIRCRAFT : CLASSIFICATION AND PARTS • LOCATION AND TYPE OF LANDING GEAR • RETRACTABLE • NON RETRACTABLE • TAIL WHEEL • NOSE WHEEL

  6. AIRCRAFT : CLASSIFICATION AND PARTS • CLASSIFICATION BY POWER PLANTS • POWER PLANT TYPES • PISTON ENGINE • TURBO PROP • TURBO SHAFT • TURBO JET • TURBO FAN • ROCKET • NUMBER OF ENGINES • SINGLE ENGINE • TWO ENGINE • MULTI ENGINE • LOCATION OF THE ENGINES • NOSE • FUSELAGE • JET ENGINE SUBMERGED IN WING • PYLON MOUNTING

  7. AIRCRAFT : CLASSIFICATION AND PARTS • TYPES OF FUSELAGE • ROUND • SQUARE • OVAL

  8. AIRCRAFT : CLASSIFICATION AND PARTS 5. CLASSIFICATION BY PURPOSE A. CIVIL B. CARGO C. MILITARY I. BOMBERS II. FIGHTERS III. INTERCEPTORS

  9. FLIGHT CONTROL SURFACE • PRIMARY GROUP • AILERON • ELEVATOR • RUDDER • SECONDARY GROUP • TRIM TAB • SPRING TAB • AUXILIARY GROUP • WING FLAPS • SPOILERS • SPEED BRAKES • LEADING EDGE FLAP • SLOTS

  10. AILERON • Longitudinal axis extends lengthwise from the nose through the tail. Movement about the longitudinal axis is called roll.  Roll is controlled by the ailerons.

  11. ELEVATOR • Lateral axis extends crosswise from wingtip through wingtip. Movement about the lateral axis is called pitch. Pitch  is controlled by the elevator.

  12. RUDDER • Vertical axis passes vertically through the center of gravity (when the aircraft is in level flight). Movement about the vertical axis is called yaw. Yaw is controlled by the rudder.

  13. AIRCRAFT ENGINES DIFFERENT TYPES OF AIRCRAFT ENGINES ARE • PROPELLER WITH PISTON ENGINE • JET ENGINE • TURBOPROP • TURBOFAN • TURBOJET • RAMJET • ROCKET ENGINE

  14. TURBOPROP

  15. PUSHER

  16. TURBOFAN

  17. TURBOJET

  18. TURBOJET WITH AFTERBURNER

  19. ROCKET ENGINE LIQUID FUEL SOLID FUEL

  20. AIRFOIL AN AIRFOIL IS A SURFACE DESIGNED TO OBTAIN A DESIRABLE REACTION FROM THE AIR THROUGH WHICH IT MOVES AIRFOIL GEOMETRY • CHORD LINE • MEAN CAMBER LINE • ANGLE OF ATTACK • ANGLE OF INCIDENCE

  21. FOUR FORCES OF FLIGHT

  22. DRAG • DRAG IS THE RESOLVED COMPONENT OF THE COMPLETE AERODYNAMIC FORCE WHICH IS PARALLEL TO THE FLIGHT DIRECTION (OR RELATIVE ONCOMING AIRFLOW). • IT MUST ALWAYS ACT TO OPPOSE THE DIRECTION OF MOTION. • IT IS THE UNDESIRABLE COMPONENT OF THE AERODYNAMIC FORCE WHILE LIFT IS THE DESIRABLE COMPONENT

  23. TYPES OF DRAG

  24. DRAG POLAR

  25. TOPICS TO BE COVERED • Why should we study properties of • atmosphere? • Variation of Temperature with Altitude • Variation of Pressure with Altitude • Variation of Density with Altitude • Tables of Standard Atmosphere

  26. Why should we study Atmospheric Properties • Engineers design flight vehicles, turbine engines and rockets that will operate at various altitudes. • They can not design these unless the atmospheric characteristics are not known. • For example,

  27. What is a standard atmosphere? • Weather conditions vary around the globe, from day to day. • Taking all these variations into design is impractical. • A standard atmosphere is therefore defined, that relates fight tests, wind tunnel tests and general airplane design to a common reference. • This common reference is called a “standard” atmosphere.

  28. Powered Controls May take one of two basic forms: Servo-assisted Hydraulic pressure transmitted to servo actuator which assists mechanical linkage to move surface. Linkage still available if power is lost but system then very heavy to operate. Fully power-operated Control signals transmitted hydraulically, electrically (fly-by-wire) or optically (fly-by-light).

  29. AIRCRAFT INSTRUMENTS

  30. INTRODUCTION • HISTORY • THE VERY FIRST AIRCRAFT HAD LITTLE TO NO FLIGHT INSTRUMENTS • ALL WEATHER FLYING WAS RISKY • NAVIGATION DEPENDED ON PILOT’S ABILITY TO USE LANDMARKS

  31. AIRCRAFT INSTRUMENTS • FLIGHT INSTRUMENTS • ENGINE INSTRUMENTS • NAVIGATION AND COMMUNICATION INSTRUMENTS

  32. THE COMMON FLIGHT INSTRUMENTS • ALTIMETER • AIRSPEED INDICATOR • VERTICAL SPEED INDICATOR • HEADING INDICATOR • ATTITUDE INDICATOR (“ARTIFICIAL HORIZON”) • TURN COORDINATOR

  33. AIRCRAFT CONSTRUCTION

  34. TRUSS

  35. MONOCOQUE

  36. SEMI MONOCOQUE

  37. THANK YOU
