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 ...
Alpina B7 (F02) (rear view; post face-lift) Interior The B7 is based on the BMW 750i and the 750Li and uses a modified version of its 4.4-litre N63 twin-turbocharged V8 engine. The modifications include large 44 mm (2 in) Honeywell turbochargers, reinforced cylinder heads, NGK spark plugs, high strength MAHLE pistons and an Alpina specific ECU.
The car, designed by Edmund Woodward Lewis (1870-1941) who had joined Rover from Daimler, had an unusual structure.Instead of the conventional chassis, the car had a backbone structure, formed by the engine crankcase, the gearbox housing, a rigid tubular propeller shaft housing, and the rear axle housing; the whole described as having a box girder section.
The original type (designated as Type 1) calls for operation at 540 revolutions per minute (rpm). A shaft that rotates at 540 rpm has six splines on it, and a diameter of 1 + 3 ⁄ 8 inches (35 mm). [10] Two newer types, supporting higher power applications, operate at 1000 rpm and differ in shaft size. [10]
25 mm to 60 mm with 5 mm steps; 60 mm to 110 mm with 10 mm steps; 110 mm to 140 mm with 15 mm steps; 140 mm to 500 mm with 20 mm steps; The standard lengths of the shafts are 5 m, 6 m and 7 m. Usually 1m to 5m is used.
The BMW N20 is a 1.6 and 2.0 L (98 and 122 cu in) turbocharged four-cylinder DOHC petrol engine with variable valve lift and variable valve timing which replaced the N53 (or BMW N52 in some markets) and was produced from 2011 to 2017 by BMW. Although the N20 is a four-cylinder engine, it is considered a replacement for the naturally aspirated ...
Headframe of the #1 Shaft at Oyuu Tolgoi. A steel headframe is less expensive than a concrete headframe; the tallest steel headframe measures 87 m. [4] Steel headframes are more adaptable to modifications (making any construction errors easier to remedy), and are considerably lighter, requiring less substantial foundations.
The 229 cu in (3.8 L) used the same 2.45-inch (62.2 mm) main bearing and 2.1-inch (53.3 mm) rod bearing diameters as the 200 cu in (3.3 L) V6 engine. Also like the 200 cu in (3.3 L) V6, the 229 cu in (3.8 L) used the same crankshaft with the 18-degree offset throws and the same 5.7-inch (140 mm) connecting rods with 0.05-inch (1.3 mm) narrowed ...
