- Aerodynamics is the air or any kind of gas that affects all moving objects
- A plane uses aerodynamics to fly the air flows over the wings creating lift and the engine or propeler propels it forward creating thrust otherwise the plane would lift off slightly but most likely crash
- A helicopter spins its main propeller to lift it off the ground then It Leans its propeller from one side in order to fly in different directions and the second propeller pushes it through the air
- The forces of aerodynamics are: Lift,Thrust,Drag,and Weight
- Thrust propels the aircraft
- Drag is the air you propel through
- Lift helps the aircraft fly off the ground
- Weight + gross weight pulls the aircraft down
- Gross weight is the extra weight of the pilot,passengers,luggage,etc...
Weight is the force that pulls the aircraft down with its weight and gravitational pulls pulling it down to earth.
Gross weight is basically the same as weight but it's the weight of the pilot,passengers,luggage,etc... Adding to the weight of the aircraft. Lift is the opposite of weight lift is created by the air flowing over the air foil of the plane witch is it's wings and the helicopters rotters blades. Thrust is created by the propeller or the engine of the air craft. Thrust pushes the aircraft forward through the air. Drag is the air that is slowing the air craft down from the parts that air takes more time to pass over. Air foil is the shape of the wing of a plane or the rotters of a helicopter. The airfoil's front edge is wider than the rear one witch is much skinnier than the front. Both top and bottom of the airfoil has a curve. The tops is much bigger than the bottom one with a smaller curve. Since the upper side takes air longer to flow over and the bottom quicker witch generates lift. |
