In aviation , a strake is an aerodynamics aerodynamic surface generally mounted on the fuselage of an aircraft to improve the airflow and hence the flight characteristics. In general a strake is longer than it is wide, in contrast to a winglet or a Wing configuration Minor aerodynamic surfaces moustache . Leading edge root extension s LERX are also sometimes referred to as wing strakes . Usage Many supersonic jet designs suffer from marginal lateral stability. One or two large strakes are sometimes positioned under the rear fuselage, below the tail empennage , to provide adequate stability at high angles of attack when the tail fin is shielded from the main airstream by the fuselage. Typical examples can be seen on the Lockheed F 104 Starfighter and the MiG 21 . On both supersonic and subsonic types, smaller strakes are sometimes applied to the forward fuselage or elsewhere to reduce drag and improve predictability at variable angles of attack, for example on the Concorde SST . Munitions Certain air deployed munitions, particularly dumb or unguided 500 pound bombs, are often retrofitted with bolt on strake sets. Designed as an open collar with strakes fitted to the outside face, these strake sets are used to alter and normalize the aerodynamics of the weapon, yielding greater accuracy. As most such munitions were manufactured with only tail mounted stabilizer fins, the addition of longitudinal strakes proves a much cleaner flow of air around the weapon during its glide, reducing the tendency to yaw and improving terminal accuracy. Strakes are also often found on smart or guided munitions as an aid to the guidance system. By stabilizing the slipstream of air traveling over the weapon, the actions of control surfaces are much more predictable and precise, again improving the accuracy of the w ... more details

In modern boats, it is the top edge of the side where there is usually some form of stiffening.

On a Watercraft rowing rowing boat especially in Rowing sport sports , the gunwale is sometimes referred to as the saxboard .

Overview In an open boat it is often fastened to the keel and hog in such a way that it can be removed for maintenance.

The remains of the ship, and a modern reconstruction, are on display at the Lat nium archeology museum. The boat Image Latenium Gallo Roman ship mg 2218.jpg thumb The Bevaix boat was built from large oak planks and measured convert 19.40 m ft in length and around convert 2.90 m ft in beam. It is characterized by a flat bottom and the complete absence of a keel or any central plank. Its four principle bottom planks were arranged one besides the other in a way that the first plank forms the stern and the last one forms the bow ship bow . The beam of the boat was determined by the addition of L shaped bilge strake s. These strakes allowed a direct transition between the flat bottom and the sides of the boat. The spaces left between the bilge strakes and the four large bottom planks were filled by two planks with an irregular outline. The purpose of these last planks was to obtain appropriate symmetry of the bottom. The upper strakes, those above the bilge strake, did not survive. However, evidence of caulking , found on the upper edges of the bilge strakes clearly suggests that the sides had been heightened by at least one or two strakes. This, in turn, lead to estimates suggesting that the maximum height of the boat was about convert 0.80 to 0.90 m ft .

Image bilgekeel.jpg right thumb A bilge keel. A bilge keel is used to reduce the hull s tendency to Ship motions roll . Bilge keels are employed in pairs one for each side of the ship . A ship may have more than one bilge keel per side, but this is rare. Bilge keels increase hydrodynamic resistance to rolling, making the ship roll less. Bilge keels are Ship stability passive stability systems . On commercial shipping the bilge keel is the form of a Strake Shipbuilding strake , or small keel or blister, running along much of the length of the hull watercraft hull . They are typically fitted one on each side, low down on the side of the hull, so as not to increase the Draft hull draft of the vessel. In battleship s they were often quite large and used as part of the torpedo protection system. A bilge keel is often in a V shape, welded along the length of the ship at the turn of the bilge. Although not as effective as Stabilizer ship stabilizing fins , bilge keels have a major advantage in their low impact on internal ship arrangements. Unlike fins, bilge keels do not have any components inside the hull that would adversely affect cargo or mission spaces. Like fins, bilge keels have the disadvantage of increasing the hydrodynamic resistance of the vessel, thus hindering forward motion. Design considerations When designing a bilge keel, there are important decisions to consider. To minimize hydrodynamic drag, the bilge keel should be placed in way of a flowline where it does not oppose crossflow. For such a usage the ends of the bilge keel should be tapered and properly faired into the hull. Also, a bilge keel should not protrude from the hull so far that the device could be damaged when the vessel is alongside a pier , even with a few degrees of adverse heel. Bilge keels on commercial vessels should not protrude below the baseline either, where they could be damaged or fouled by grounding. Note that small bilge keels are often fitted to smaller fishing boats precisely ... more details
refimprove date December 2011 A trash rack is a wooden or metal structure, frequently supported by masonry , that prevents water borne debris such as logs, boats, animals, masses of cut waterweed, etc. from entering the intake of a water mill , pumping station or water conveyance. This protects water wheel s, penstocks , and sluice gates from destruction during flood s. Trash racks composed of vertical wooden strake s separated by narrow gaps are very common and perform extremely poorly. Metal gratings are sturdier and can have narrower strakes, and angling the trash rack properly can allow some self cleaning from the action of the water. Modern trash racks as used by hydropower hydroelectric plants can incorporate such advanced features as wedge wire wedge wire screens , the Coanda effect , and cleaning robot s. In waterways with large amounts of floating debris, various permanently installed trash rakes may be required to reduce the labor required for regular cleaning. Trash racks are designed for water velocity of around 2 feet second 0.6 metres second to prevent excessive energy loss due to the head loss across the trash rack. ref Karassik, Igor J. et al, ed.
