The Soviet Project 183R class, more commonly known as the Komar class, its NATO reporting name, meaning "mosquito", is a class of missile boats, the first of its kind, built in the 1950s and 1960s.
This direct-drive aero-engine is unusual in two respects: it is very oversquare with a bore:stroke ratio of 1.295:1, and it has a side-valve (flathead) valvetrain.The designer determined that since maximum continuous power output (65.3 kW [2]) was to be developed at only 2800 rpm, the extra weight and complexity of overhead valves (OHV) would be superfluous.
D-Motor is a Belgian aircraft engine manufacturer based in Deerlijk. The company specializes in the design and manufacture of aircraft engines for homebuilt and ultralight aircraft. [1] [2] The company was formed in about 2009 to develop an engine to replace the Rotax 582 and Jabiru 2200 in the Belgian Masquito M80 helicopter project.
The D-Motor LF39 is a lightweight liquid cooled side-valve four-stroke flat six 4 litre petrol aircraft engine, ... Width: 566 mm (22.28 in) Height: 423.4 mm (16.67 in)
The Comac C919 is a narrow-body airliner developed by Chinese aircraft manufacturer Comac.The development program was launched in 2008. Production began in December 2011, with the first prototype being rolled out on 2 November 2015; the maiden flight took place on 5 May 2017.
Ram air collected by the air intakes in the nose is used to provide power to move the control fins. [10] The 17.2 kg (37.8 pound) missile is 690 mm (27.1 inches) long and has pop-out fins (with a 250 mm/69 girth span) that aid in guidance. The missile is guided by the modulated laser beam steered by the tank gunner.
The OM646 engine is sold under the 200 CDI and 220 CDI designation and features an electric fuel pump, exhaust gas recirculation, particulate filters, [1] and Euro 4 emission standard compliance (from 2003). [2]
The switched reluctance motor (SRM) is a type of reluctance motor. Unlike brushed DC motors , power is delivered to windings in the stator (case) rather than the rotor . This simplifies mechanical design because power does not have to be delivered to the moving rotor, which eliminates the need for a commutator .
