they’re sucked up into it. This reason is known as Bernoulli’s Principle. It says: "...as air travels faster [than surrounding air] across a surface‚ the air pressure against it is reduced...". By curving the top of an airplane’s wing‚ forming an airfoil‚ air above it has to travel farther (as the distance is greater) than the air below‚ forcing the air to move faster. The result is lower pressure on top and more pressure on the bottom. Another name for this is lift. The higher pressure below the

someone on water skis? Here ’s a project on designing propellers to do the job. ObjectiveThe goal of this project is to investigate how changes in chord length affect the efficiency of propellers.IntroductionA propeller‚ like an airplane wing‚ is an airfoil: a curved surface that can generate lift when air moves over it. When air moves over the surface of a moving propeller on an airplane‚ the air pressure in front of the propeller is reduced‚ and the air pressure behind the propeller is increased. The

competitive with more conventional sources of energy such as coal. Rotor blade is a key element in a wind turbine generator system to convert wind energy in to mechanical energy. Most blades available for commercial grade wind turbines incorporate airfoil shaped cross sections. These blades are found to be very efficient at lower wind speeds in comparison to the potential energy that can be extracted. Computational fluid dynamics (CFD) is a branch of fluid mechanics that uses numerical methods and

slipstream that tends to rotate the aircraft to the left around the vertical axis‚ and to the right around the longitudinal axis. The four forces acting on an airplane in flight are lift‚ weight‚ thrust‚ and drag. Lift produced by an airfoil is the net force developed perpendicular to the relative wind. When are the four forces that act on an airplane in equilibrium? During unaccelerated flight. Which action will result in a stall? Exceeding the critical angle of attack
