The vortex lattice method is built on the theory of ideal flow, also known as Potential flow.Ideal flow is a simplification of the real flow experienced in nature, however for many engineering applications this simplified representation has all of the properties that are important from the engineering point of view.
Propeller walk (also known as propeller effect, wheeling effect, paddle wheel effect, asymmetric thrust, asymmetric blade effect, transverse thrust, prop walk) is the term for a propeller's tendency to rotate about a vertical axis (also known as yaw motion). The rotation is in addition to the forward or backward acceleration.
The Sweep Roll represents one of the earliest techniques employed in kayaking. In this maneuver, the paddler initiates an arc motion with the paddle, starting at the bow of the kayak. This technique facilitates the paddler's proximity to the water's surface, providing a tactical advantage in aerated water conditions.
Move the paddle forward, rotate the grip of the paddle in the palm of your upper hand. Then you are ready for the next power stroke without taking the blade out of the water. Pry stroke The pry stroke begins with the paddle inserted vertically in the water, with the power face outward, and the shaft braced against the gunwale. A gentle prying ...
Wing warping was an early system for lateral (roll) control of a fixed-wing aircraft or kite. The technique, used and patented by the Wright brothers , consisted of a system of pulleys and cables to twist the trailing edges of the wings in opposite directions.

The KF airfoil was designed by Richard Kline and Floyd Fogleman. Aircraft wing showing the KFm4 Step. In the early 1960s, Richard Kline wanted to make a paper airplane that could handle strong winds, climb high, level off by itself and then enter a long downwards glide.
