The wing ribs flexed under the weight of the pilot, distorting the airfoil shapes of the wings. The brothers fixed the trouble, but the wings still produced much less lift than expected, and wing-warping sometimes made the glider turn opposite the intended direction: it was the discovery and first description of adverse yaw.

It can be assumed that the animal skins were used for clothing throughout the human history, although in the ways that are primitive when compared to the modern processing, the earliest known samples come from Ötzi the Iceman (late 4th millennium BC) with his goatskin clothes made from leather strips put together using sinews, bearskin hat, and shoes using the deerskin for the uppers and ...
This is typically controlled by the rudder at the rear of the airplane. Roll (bank) – in which one wing of the airplane moves up and the other moves down. This is typically controlled by ailerons on the wings of the airplane. Coordinated flight requires the pilot to use pitch, roll and yaw control simultaneously. See also flight dynamics.
An airplane (North American English) or aeroplane (British English), informally plane, is a fixed-wing aircraft that is propelled forward by thrust from a jet engine, propeller, or rocket engine. Airplanes come in a variety of sizes, shapes, and wing configurations .
Many transports, bombers and trainers still used fabric, although the flammable nitrate dope was replaced with butyrate dope instead, which burns less readily. [4] The Mosquito is an example of a fabric-covered plywood aircraft. The Vickers Wellington used fabric over a geodesic airframe which offered good combat damage resistance.
Sharkskin has historically been made with different types of natural fibers, including mohair, wool and silk. More expensive variations exist and are often demarcated by fabric content labels bearing "Golden Fleece" or "Royal" titles. These indicate an older style of sharkskin fabric that was extremely rare and were costly to produce.
The yaw axis has its origin at the center of gravity and is directed towards the bottom of the aircraft, perpendicular to the wings and to the fuselage reference line. Motion about this axis is called yaw. A positive yawing motion moves the nose of the aircraft to the right. [1] [2] The rudder is the primary control of yaw. [3]
The rudder is a fundamental control surface which is typically controlled by pedals rather than at the stick. It is the primary means of controlling yaw—the rotation of an airplane about its vertical axis. The rudder may also be called upon to counter-act the adverse yaw produced by the roll-control surfaces.
