Paddle – used in kayaks and canoes for propulsion and made of plastic, wood, fiberglass, carbon fiber or metal. Paddles for use in kayaks are longer, with a blade on each end and are handled from the middle of the shaft; Paddle float – buoyance aid fitted to paddle used for re-entry into a kayak after a capsize in open water. It may also be ...
the rear of the F135 engine (nozzle rotated down) that powers the Rolls-Royce LiftSystem. Instead of using separate lift engines, like the Yakovlev Yak-38, or rotating nozzles for engine bypass air, like the Harrier, the "LiftSystem" has a shaft-driven LiftFan, designed by Lockheed Martin and developed by Rolls-Royce, [3] and a thrust vectoring nozzle for the engine exhaust that provides lift ...
Sprint kayak is a type of canoe sprint held on calm water. The paddler is seated, facing forward, and uses a double-bladed paddle pulling the blade through the water on alternate sides to propel the boat forward. Kayak sprint has been in every summer Olympics since it debuted at the 1936 Summer Olympics. [1]
Over these four distances, the ICF recognizes six boat classes, known as 'International Boats'. These are: K1, K2, K4, C1, C2, and C4, where the number indicates the size of the crew and “K” stands for kayak and “C” for canoe. [10] Thus "MK1 1000m" would stand for a male one-person kayak racing over 1000 meters.
True sea kayaks, not to be mistaken for wider, more stable recreational kayaks, are available in many designs. The length of a solo sea kayak can range anywhere from 4.3 to 6.1 m (14 to 20 ft) long, and tandem kayaks can range from 5.5 to 7.3 m (18 to 24 ft) long. Sea kayaks can range in width (beam) from 22 to 24 inches wide. [15]

Johnson Lifts started out doing lift maintenance. [8] The company installed its first lift at the New Woodlands Hotel in Chennai in 1966. [1] It began manufacturing lifts in 1970. [8] Johnson Lifts started out with a small manufacturing unit at Vyasarpadi, before moving to a larger facility in Ambattur in 1988. [9] K.J. John died in 2002. [8]
Lift is proportional to the density of the air and approximately proportional to the square of the flow speed. Lift also depends on the size of the wing, being generally proportional to the wing's area projected in the lift direction. In calculations it is convenient to quantify lift in terms of a lift coefficient based on these factors.
