Adverse yaw!!! Roll causes Yaw and Yaw causes Roll...

Image
Do you know what adverse yaw is and how to solve it? To understand what adverse yaw is, we need to first explain the axes of motion for an  airplane. An aircraft in flight can rotate around three different axes, as illustrated below. Aircraft control surfaces However, the effect of one control surface is not always limited to just pitch, roll, or yaw  alone. When the deflection of one control surface affects more than one of these  orientations, we say that the orientations are coupled. The most important of these  coupled interactions is adverse yaw. To better understand the concept, let's study a  picture of what happens when the pilot deflects the ailerons to roll the aircraft. As you can see, the aircraft rolls because one aileron is deflected downward while the other is deflected upward. Lift increases on the wing with the downward-deflected aileron because the deflection effectively increases the camber of that portion of the wing. Conversely, lift decreas...

Aircraft Landing Gear

Image
Why do aircraft have only three landing gear? Why not four? Most aircraft today have three landing gear. Two main landing gear struts located near the middle of the aircraft usually support about 90% of the plane's weight while a smaller nose strut supports the rest. This layout is most often referred to as the "tricycle" landing gear arrangement. However, there are numerous other designs that have also been used over the years, and each has its own advantages and disadvantages. Let's take a closer look at the various undercarriage options available to engineers. Tail-wheel or Tail-dragger :  Gear Though the tricycle arrangement may be most popular today, that was not always the case. The tail-wheel undercarriage dominated aircraft design for the first four decades of flight and is still widely used on many small piston-engine planes. The tail-dragger arrangement consists of two main gear units located near the center of gravity (CG) that support the majority of the p...
