Lift Lifting and Lifting Helping

Lift Lifting and Lifting Helping. First we need Airfoils. a body (as an airplane wing or propeller blade) designed to provide a desired reaction force when in motion relative to the surrounding air. This force can come in the form of lift, drag, stability and control. Airfoil Aspects.

  1. Lift Lifting and Lifting Helping

  2. First we need Airfoils • a body (as an airplane wing or propeller blade) designed to provide a desired reaction force when in motion relative to the surrounding air. • This force can come in the form of lift, drag, stability and control.

  3. Airfoil Aspects

  4. Types of Airfoils

  5. Definitions • Camber – the curvature of the airfoil • Chord Line – A reference line to go from leading edge to trailing edge • Chord line is used to discuss two angular definitions

  6. Angles • Angle of Attack – the angular difference between the airplanes relative wind and the wings chord line • Angle of Incidence - the angular difference between the longitudinal axis of the airplane and the wings chord line • Pitch Angle – the difference between the longitudinal axis of the airplane and the horizon

  7. Angle of Attack

  8. Angle of Attack • All factors being equal lift will increase with an increase in angle of attack.

  9. Angle of Attack • Ways to change AoA • Changing pitch • Changing the shape of the airfoil

  10. Angle of Incidence

  11. Lift Adding Devices

  12. Lift Adding Devices

  13. Lift Adding Devices • Aspect Ratio – The ratio between a wings chord and its span. The larger the aspect ratio the less force needed to create lift. Thus larger aspect ratio requires less thrust. 27:1 Aspect Ratio
