  • Magnus effect

    Some aircraft have been built to use the Magnus effect to create lift with a rotating cylinder instead of a wing, allowing flight at lower horizontal speeds. The earliest attempt to use the Magnus effect for a heavierthanair aircraft was in 1910 by a US member of Congress, Butler Ames of Massachusetts. The next attempt was in the early 1930s by three inventors in New York state.

    Aerodynamic Lift and Drag and the Theory of Flight . The wings of birds were the original inspiration for the design of aerofoils however it was not until 1799 that engineer George Cayley carried out the first methodical study of the performance of aerofoils. His publiion "On Aerial Navigation" in 1810, marked the beginning of the science of Aerodynamics.

  • The Basics of AXIAL FLOW FANS

    An axial flow fan moves air or gas parallel to the axis of rotation. By comparison, a centrifugal or radial flow fan moves air perpendicular to the axis of rotation. Axial flow fans are better suited for lowresistance, highflow appliions, whereas centrifugal flow fans apply to highpressure resistance, lowflow conditions. Typically, the types of fans discussed in this manual can .

    As the air flows through the engine, each rotor is free to operate at its own efficient speed. These speeds are all quite precise and are carefully calculated by the engineers who designed the engine. The speed in RPM of each rotor is often displayed on the engine flight deck and identified by gages or readouts labeled N1 RPM and N2 RPM. Both rotors have their own .
