The Capstan is a high-winged monoplane of wooden construction, the last two-seat wooden glider built by Slingsby, [1] intended for both training and general club flying. Side-by-side seats for the two pilots are accommodated in an enclosed cockpit with a one-piece perspex canopy. The prototype T.49A first flew in 1961, and it entered production ...
A capstan is a vertical- axled rotating machine developed for use on sailing ships to multiply the pulling force of sailors when hauling ropes, cables, and hawsers. The principle is similar to that of the windlass, which has a horizontal axle. The capstan and the anchor windlass on the deck below that it drives.
Fletcher. -class destroyer. The Fletcher class was a class of destroyers built by the United States during World War II. The class was designed in 1939, as a result of dissatisfaction with the earlier destroyer leader types of the Porter and Somers classes. Some went on to serve during the Korean War and into the Vietnam War.
The capstan equation[ 1 ] or belt friction equation, also known as Euler–Eytelwein formula[ 2 ] (after Leonhard Euler and Johann Albert Eytelwein), [ 3 ] relates the hold-force to the load-force if a flexible line is wound around a cylinder (a bollard, a winch or a capstan). [ 4 ][ 1 ] It also applies for fractions of one turn as occur with ...
Fletcher FU-24-950M of Fieldair at Thames airfield New Zealand in 1992. FU-24 c/n1 flew on 14 June 1954 in the United States as N6505C, then was disassembled for shipment to New Zealand where it flew as ZK-BDS. This original prototype had a 225 hp (168 kW) engine and open cockpit. Prior to production commencing the design was altered to add an ...
A capstan on a sailing ship. This model is manually driven by inserting long beams in the holes seen at the top. A torque amplifier is essentially two capstans connected together. A capstan consists of a drum that is connected to a powerful rotary source, typically the steam engine of the ship, or an electric motor in modern examples. To use ...
USCGC Bollard breaking light ice. The USCG 65' small harbor tug is a class of fifteen tugs used by the United States Coast Guard for search and rescue, law enforcement, aids-to-navigation work and light icebreaking. The tugs are capable of breaking 18 in (0.46 m) of ice with propulsion ahead and 21 in (0.53 m) of ice backing and ramming. [2]
The Turbo-Cat was a jet aircraft catapult launch system powered by six jet engines. It was invented by Don Doolittle, and manufactured by the All American Engineering Co. of Wilmington, Delaware, USA. Six Allison J33 engines in a capstan arrangement provided 50,000 horsepower directly to the launching cable. It was developed for expeditionary ...
