Back to Teacher Overview Outline Teacher Background See Student Informational Reading: Orbiter Control Vocabulary 1. aileron: Control surfaces on the trailing edge of each wing that affect the motion of roll. 2. axis: A straight line through the center of gravity around which an aircraft rotates. 3. center of gravity: A point on an airplane at which the entire weight of the airplane is considered concentrated so that if the airplane is supported at this point the airplane would remain in equilibrium (or balance). 4. drag: The force that resists the motion of the aircraft through the air. 5. elevator: Control surfaces on the horizontal part of the tail section (horizontal stabilizer) that affects the motion of pitch. 6. elevon: Control surfaces located on the trailing edge of a delta wing airplane that control the motion of pitch and roll. 7. force: A push or pull in a certain direction that can be measured. 8. lift: Upward force produced by air passing over and under the wing of an airplane. 9. lateral axis: The axis extending through the center of gravity of an airplane and parallel to a line connecting the tips of the wings. 10. longitudinal axis: The axis extending through the center of the fuselage from the nose to the tail. 11. pitch: A rotational motion in which the aircraft turns around its lateral axis by raising or lowering the nose of the airplane. 12. roll: A rotational motion in which the aircraft turns around its longitudinal axis by raising one wing higher as the other wing dips lower. 13. rudder: A control surface o nthe trailing edge of the vertical part of the tail section (vertical stabilizer) that affects the motion of yaw. 14. thrust: A force created by the engines that pushes an aircraft through the air. 15. weight: A force of gravity acting on an object. 16. vertical axis: The axis extending straight up and down through the center of gravity of an aircraft. 17. yaw: A rotational motion in which the aircraft turns around its vertical axis by moving the nose of the aircraft to the pilot's left or right. Prerequisite Knowledge 1. Familiarity with the motions of an airplane: roll, pitch, yaw. 2. Familiarity with the 3 axes: lateral, longitudinal and vertical. Skills 1. Reading for meaning 2. Observation of flight 3. Data collection Concepts 1. Rudder affects the motion of yaw (horizontal axis). 2. Elevon is a control surface located along the trailing edge of a delta wing and is actually a combination of an elevator and an aileron. 3. The elevator (inner elevon on the orbiter's delta wings) affects the motion of pitch (vertical axis). 4. The aileron (outer elevon on the orbiter's delta wings) affects the motion of roll (lateral axis). 5. Ailerons (outer elevons) work in opposition. 6. Elevators (inner elevons) work in tandem. Processes 1. Use the scientific method to answer a question. 2. Perform research to gather additional information. 3. Making models.
