    The lift and drag characteristics of NACA 0012, 1408, 2412, and 4412 airfoils are characterized using a 6” by 6” subsonic wind tunnel equipped with a force balance. The axial and normal forces on the airfoil are measured at angles of attack ranging from -8° to 28° and used to determine lift and drag forces. Lift, drag, and drag polar curves are generated using experimental data. Lift coefficients are found to increase linearly with increasing angle of attack up to the critical angle of attack. Drag

    which is the airflow that caused by the forward motion of the aircraft. It acts in the direction that is parallel to the flight path but in the opposite direction. In this case, the force that acts perpendicular to the airflow will be equal to the lift force. However, for the ornithopters, there are two airflows passing through its aerofoil. The first component is the same as the normal aircraft. However, the second component is the airflow that caused by the flapping motion of the wings. The direction

  • Importance Of Aerodynamics

    1391 Words  | 6 Pages

    Aerodynamics is one of the most important objects of study because they provide the bases for flight and the designing of not only aircraft, but also cars, spacecraft, and buildings. Aerodynamics work through the combination of three forces, thrust, lift, drag, and weight. In 350 B.C., Aristotle devised the idea that air has weight and he examined that an object moving through a fluid experiences resistance, or drag. Drag is the force of air opposition propelling in the reverse direction of an aircraft

    we known, during flight, there are four forces acting on the airplane. Those are LIFT, DRAG, THRUST, and WEIGHT. In order to make the wings to move in the air, of course, the plane itself has to move. A helicopter works by having its wings move through the air while the body stays still. The helicopter's wings are also called Main Rotor Blades. Depend on the shape and the angle of the wings will determine how much Lift force is needed. After the helicopter lifted off the ground, the pilot can tilt

  • Essay On Flight Control

    Extending these slats creates even more lift, this allows the plane to fly at lower speeds without dropping altitude. Slats allow air to flow smoothly along the surface of the wing. Sometimes air is unable to follow the surface of the wing and becomes turbulent which can affect lift, the use of slats reduces this problem. The difference between slots and slats is that Slats can be retracted to be flush with the

    maneuvers that help them in their journeys. Some of the likes as decreasing their surface area to decrease drag across the opposing flow of the fluid. They achieve this by closing their wings, which will increase their speed. They also try to increase lift by rapidly flapping its wings to push it upwards. As stated later, they also use their large flight muscles to produce thrust that allows them easier passage. Another very important strategy that large winged animals use is the soaring one. Their large

    Flying in the Theatre A system of ropes, pulleys and counterweights is used in a theatre in order to lift scenery, flats and sometimes people among other theatre hardware. This system is commonly known as a fly system or a rigging system. Flying people can be a dangerous act and must be carried out by a competent person with adequate training and experience. A fly system consists of battens, lines (made of both hemp and wire), blocks, a cradle and counterweights. When flying people a harness is also

  • Aircraft Wings Advantages And Disadvantages

    811 Words  | 4 Pages

    The aircraft wings are the primary lift producing device for an aircraft. The aircraft wings are designed aerodynamically to generate a lift force which is required in order for an aircraft to fly. Besides generating the necessary lift force, the aircraft wings are used to carry the fuel required for the mission of the aircraft, can have mounted engines or can carry extra fuel tanks or other armaments. The basic goal of the wing is to generate lift and minimize drag as far as possible. When the

    1655 Words  | 7 Pages

    The Elevons are present in an aircraft control surfaces that which will combine the functions of a elevator and a aileron. These elevons are frequently utilized on the tailless aircraft such as flying with wings. The elevon that is not part of the main wing, but instead is a separate tail surface, is a stabilator (but stabilators are also used for pitch control only, with no roll function, as on the Piper Cherokee series of aircraft). The word "elevon" is a portmanteau of elevator and aileron. Elevons

    flight. Some of the most dangerous types of turbulence are wake vortex, mountain wave, and clear air. Each of these types have specific characteristics and conditions in which they occur. Wake vortex turbulence is produced by an aircraft generating lift. Wake vortices are produced when the high-pressure air under the aircraft wing flows to the low-pressure area on top of the wing by the shortest means possible at the wing tips. The pressure differential that causes this movement is greatest
