1 Part 2 - Pitch and Roll Yaw Transportation TechnologyFlightPart 2 - Pitch and Roll Yaw
2 Objectives of the Day Objectives Students will be able to list the axis on which a plane can turnStudents will be able to describe how Bernoulli's principle worksStudents will be able to list and explain controlling parts of an Airplane.Students will complete Paper Planes Construction, Begin Design Process for Wooden Planes.
3 There are 3 main Rotations of a Plane The Axes of AirThere are 3 main Rotations of a PlanePITCH ROLL YAW
4 The Axes of AirThere are 3 main Rotations of a PlanePITCH ; The Aircraft PITCHES around the Lateral or WING Axis.(i.e. The Plane Flips Forwards or Backwards)
5 The Axes of AirThere are 3 main Rotations of a PlaneROLL ; The Aircraft ROLLS around the Longitude or Fuselage Axis.(i.e. The Plane does a “Barrel Roll”)
6 The Axes of Air YAW ; The Aircraft YAWS around the Vertical Axis. There are 3 main Rotations of a PlaneYAW ; The Aircraft YAWS around the Vertical Axis.(i.e. The Plane revolves around in a 360°Fashion)
7 Airfoils and Air Pressure LowHighAir Pressures around an Air FoilLow Air Pressure on top of the airfoil, High Air Pressure on the bottom of the airfoil.What does this cause to happen?
8 Bernoulli’s Principle LowHighThe Basics of Bernoulli’s PrincipleAs the velocity of the air moves increases, the pressure of the air decreases.
10 Controlling PartsHORIZONTAL STABILIZERPart of the Airplanes Tail that Helps keep the airplane stable on the PITCH Axis during Flight.
11 Controlling PartsVERTICAL STABILIZERPart of the Airplanes Tail that Helps keep the airplane stable on the YAW Axis during Flight.
12 Controlling PartsAILERONSParts that move in opposite direction of each other and cause the plane to roll to whichever side the aileron is up.ELEVATORSParts that move up or down that cause the plane to Pitch in the opposite direction. If the Elevator is up, the nose of the plane will pitch down, and vice-versa.
13 Controlling PartsFLAPSFlaps that move up and down together to increase or decrease DRAG on the plane.RUDDERThe Rudder moves Left and Right and causes the plane to YAW left or right. It is the sole part that controls the YAW axis.
14 DESIGN CHALLENGEYou are to design a wooden plane that can maintain air flight for at least 10 seconds or more when flown outside. You may use the design style given to you, or be innovative and come up with your own style.
15 DESIGN CHALLENGEYou must use and show the 12 steps of the design process in your design. You must complete the research directed questions and evaluation worksheet on your design.
16 Review QuestionsWhat are the three axes of flight? What controlling part causes the plane to increase or decrease drag? What does the Elevator on a plane do? What part moves the plane on the YAW Axis?
