Aerodynamics Aerodynamics is the study of objects in motion through the air and the forces that produce or change such motion. INTRODUCTION It is unnecessary that a mechanic be totally  versed  on  Aerodynamics   and  Theory  of  Flight .  However  he  must understand  the  relationships  between  the  atmosphere,  the aircraft and the forces acting on it in  flight,  in  order  to  make intelligent decisions affecting the flight safety of both  airplanes  and  helicopters.
The Atmosphere Air is a mixture of gases composed principally of  nitrogen and  oxygen.  An  aircraft  operates  in  the air,  therefore,  the properties of air that affect aircraft control and performance must be understood. Pressure   –  Atmospheric  pressure  varies  with  altitude.  The higher an object rises above sea level, the lower  the  pressure. Density  – It varies directly with the pressure and inversely with the temperature. With the same horse power, an aircraft can fly faster at high altitude because of less resistance of air at there. Humidity  – Humidity is the amount of water vapor in the air. It varies directly with temperature.
Newton's First Law of Motion According to Newton's first law of motion (inertia), an object at rest will remain at rest, or an object in motion  will  continue  in motion at the same speed and in the same  direction,  until  an outside force acts on it. For an aircraft  to  taxi  or  fly,  a  force must  be  applied  to  it.  It  would  remain  at  rest  without  an outside force. Once the aircraft is moving, another force must act on it  to  bring  it  to  a  stop.  It  would  continue  in  motion without  an  outside  force.  This  willingness  of  an  object  to remain at rest or to continue in motion is referred to as  inertia .
Newton's Second Law of Motion The second law of motion (force) states that if a object  moving with uniform speed is  acted  upon  by  an  external  force,  the change of motion (acceleration) will be directly  proportional  to the amount of force and inversely proportional to the  mass  of the object  being  moved.  The  motion  will  take  place  in  the direction in which the force acts. Simply stated, this means that an object being pushed by 10 pounds of force will travel  faster than it would if it were pushed by 5 pounds of force. A  heavier object will accelerate more slowly than a lighter object when an equal force is applied.    F = m  ×  a

  • 3. Aerodynamics Aerodynamics is the study of objects in motion through the air and the forces that produce or change such motion. INTRODUCTION It is unnecessary that a mechanic be totally versed on Aerodynamics and Theory of Flight . However he must understand the relationships between the atmosphere, the aircraft and the forces acting on it in flight, in order to make intelligent decisions affecting the flight safety of both airplanes and helicopters.
  • 4. The Atmosphere Air is a mixture of gases composed principally of nitrogen and oxygen.

The higher an object rises above sea level, the lower the pressure. Density – It varies directly with the pressure and inversely with the temperature. With the same horse power, an aircraft can fly faster at high altitude because of less resistance of air at there. Humidity – Humidity is the amount of water vapor in the air. It varies directly with temperature.
  • 5. Newton's First Law of Motion According to Newton's first law of motion (inertia), an object at rest will remain at rest, or an object in motion will continue in motion at the same speed and in the same direction, until an outside force acts on it. For an aircraft to taxi or fly, a force must be applied to it. It would remain at rest without an outside force. Once the aircraft is moving, another force must act on it to bring it to a stop. It would continue in motion without an outside force. This willingness of an object to remain at rest or to continue in motion is referred to as inertia .
  • 6. Newton's Second Law of Motion The second law of motion (force) states that if a object moving with uniform speed is acted upon by an external force, the change of motion (acceleration) will be directly proportional to the amount of force and inversely proportional to the mass of the object being moved. The motion will take place in the direction in which the force acts. Simply stated, this means that an object being pushed by 10 pounds of force will travel faster than it would if it were pushed by 5 pounds of force. A heavier object will accelerate more slowly than a lighter object when an equal force is applied. F = m × a
  • 7. Newton's Third Law of Motion The third law of motion (action and reaction) states that for every action (force) there is an equal and opposite reaction (force). This law can be demonstrated with a balloon. If you inflate a balloon with air and release it without securing the neck, as the air is expelled the balloon moves in the opposite direction of the air rushing out of it. Figure shows this law of motion. Action Reaction Balloon Air

  • 42. CONTROL To achieve the best performance, the aircraft must have the proper response to the movement of the controls. Control is the action taken to make the aircraft follow any desired flight path. Different Control surfaces are used to control the aircraft about each of the three axes. Flight Control Surfaces – Hinged or moveable airfoils designed to change the attitude of the aircraft during flight. 1. Primary group - ailerons - elevators - rudder 2. Secondary group - trim tab, spring tab - servo tab, balance tab 3. Auxiliary group - wing flaps - spoilers - speed brakes - slats - leading edge flaps - slots

  • 45. Ailerons – The ailerons form a part of the wing and are located in the trailing edge of the wing towards the tips. The control stick is connected by means of wires or hydraulics to the wings’ ailerons. By turning the stick, the pilot can change the positions of the ailerons. ROLLING Control around the Longitudinal Axis
  • 46. Rudder – The rudder is a moveable control surface attached to the trailing edge of the vertical stabilizer. The foot pedals are connected by means of wires or hydraulics to the rudder of the tail section. The rudder can also be used in controlling a bank or turn in flight. YAWING Control around the Vertical Axis Moving rudder to the right forces tail to the left, nose to the right Moving rudder to the left forces tail to the right, nose to the left.
  • 47. Elevators – Elevators are the movable control surfaces hinged to the trailing edge of the horizontal stabilizer. The control stick is connected by means of wires or hydraulics to the tail section’s elevators. - Stabilator - Ruddervator PITCHING Control around the Lateral Axis

Editor's Notes

  1. Discuss weight from lift equation POV.
  2. Propeller is a rotating airfoil.
  3. The stick is connected by means of wires or hydraulics to the wings’ ailerons. By turning the stick, the pilot can change the positions of the ailerons . When the control wheel is turned to the right, the right aileron goes up and the left aileron goes down, rolling the airplane to the right. When the control wheel is turned to the left, the right aileron goes down and the left aileron goes up, rolling the airplane to the left.
  4. Rudder: The foot pedals are connected by means of wires or hydraulics to the rudder of the tail section. The rudder is the vertical part of the tail that can move from side to side. When the foot pressure on the left rudder pedal moves the rudder to the left, causing the nose of the airplane to move to the left.
  5. The stick (joy stick) is connected by means of wires or hydraulics to the tail section’s elevators. By moving the stick, the pilot can change the position of the elevators. When the control column is pushed in, the elevators move down, pitching the tail of the airplane up an the nose down, rolling the airplane down. When pulling the control column back makes the elevators move up, pitching the tail of the airplane down and the nose up, rolling the airplane upwards. Cars go only left or right, but planes must be steered up or down as well. A plane has parts on its wings and tail called control surfaces to help it. These can be demonstrated by use of folded paper gliders and balsa gliders. Let’s start with an experiment to illustrate how a plane is controlled.
