The secret site was officially called "Inchindown, Royal Navy Fuel Tanks" and also known as the "Invergordon Oil Fuel Depot". [3] The complex consists of six tanks: five are 237 m (778 ft) long, 9 m (30 ft) wide, with arched roofs 13.5 m (44 ft) high; a smaller sixth tank is of the same height and breadth but shorter. [4]
The current formulation of 100LL (low lead, blue) aviation gasoline contains 2.12 grams per US gallon (0.56 g/L) of TEL, half the amount of the previous 100/130 (green) octane avgas (at 4.24 grams per gallon), [85] and twice as much as the 1 gram per gallon permitted in regular automotive leaded gasoline prior to 1988 and substantially greater ...
The first tank-to-tank engagement occurred in mid-1968 when a US reconnaissance airplane observed a PT-76 being washed by its crew in the Bến Hải River in the DMZ (17th Parallel). The Forward Air Control pilot radioed the tank's position to a nearby M48 Patton tank unit of the US 3rd Tank Battalion .
An emergency main ballast tank blow is a procedure used aboard a submarine that forces high-pressure air into its main ballast tanks. The high-pressure air forces ballast water from the tanks, quickly lightening the ship so it can rapidly rise to the surface.
The Mark 8 Landing Craft Tank (also referred to as the LCT (8) or LCT Mark VIII) were landing craft tank ships operated by the British Armed Forces. The vessels were based on an American design, but improved into ocean-going vessels capable of sailing to and operating in the Far East .
Cross section of a vessel with a single ballast tank at the bottom. A ballast tank is a compartment within a boat, ship or other floating structure that holds water, which is used as ballast to provide hydrostatic stability for a vessel, to reduce or control buoyancy, as in a submarine, to correct trim or list, to provide a more even load distribution along the hull to reduce structural ...
Eutectic alloys for soldering, both traditional alloys composed of lead (Pb) and tin (Sn), sometimes with additional silver (Ag) or gold (Au) — especially Sn 63 Pb 37 and Sn 62 Pb 36 Ag 2 alloy formula for electronics - and newer lead-free soldering alloys, in particular ones composed of tin, silver, and copper (Cu) such as Sn 96.5 Ag 3.5.
The "Vessel Boiling Electric" or "BV" was an innovation at the very end of World War II, when the Centurion tank was introduced with the device fitted inside the turret. [2] [3] Previously, British tank crews had disembarked when they wanted to "brew-up" (make tea), using a petrol cooker improvised from empty fuel cans [4] called a "Benghazi burner". [5]
