Two points on a fuselage at waterline 100/fuselage station 93 and waterline 101/fuselage station 276. Lofting coordinates are used for aircraft body measurements. The system derives from the one that was used in the shipbuilding lofting process, with longitudinal axis labeled as "stations" (usually fuselage stations, frame stations, FS), transverse axis as "buttocks lines" (or butt lines, BL ...
The waterline is the line where the hull of a ship meets the surface of the water. A waterline can also refer to any line on a ship's hull that is parallel to the water's surface when the ship is afloat in a level trimmed position. Hence, waterlines are a class of "ships lines" used to denote the shape of a hull in naval architecture lines ...
A water tunnel is an experimental facility used for testing the hydrodynamic behavior of submerged bodies in flowing water. It functions similar to a recirculating wind tunnel , but uses water as the working fluid, and related phenomena are investigated, such as measuring the forces on scale models of submarines or lift and drag on hydrofoils .
The tropical load line is one forty-eighth of the summer load draft above the summer load line. The fresh water load line is an amount equal to Δ / 4T millimetres above the summer load line where Δ is the displacement in tonnes at the summer load draft and T is the tonnes per centimetre immersion at that draft. In any case where Δ ...
The Dutch Water Defence lines (Dutch: Hollandse Waterlinies) [1] is a UNESCO World Heritage Site in the Netherlands comprising the New Dutch Waterline and Stelling van Amsterdam. The Stelling van Amsterdam was added as a World Heritage Site in 1996, and was extended in 2021 with the New Dutch Waterline in 2021.
Dryer lint is lint generated by the drying of clothes in a clothes dryer; it typically accumulates on a dryer screen. Underwriters Laboratories recommends cleaning the lint filter after every cycle for safety and energy efficiency. [6] Failure to clean the lint filter is the leading cause of home clothes dryer fires. [7]
The test method consists of pushing an instrumented cone, with the tip facing down, into the ground at a controlled rate (controlled between 1.5 -2.5 cm/s accepted). The resolution of the CPT in delineating stratigraphic layers is related to the size of the cone tip, with typical cone tips having a cross-sectional area of either 10 or 15 cm 2 ...
A knife edge at the point source-image location is positioned as to partially block some light from reaching the viewing screen. The illumination of the image is reduced uniformly. A second lens is used to image the test section to the viewing screen. The viewing screen is located a conjugate distance from the plane of the schliere.
