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.
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.
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.
COMAC chose Collins Aerospace Pro Line 21 integrated avionics system (IAS) as their flight deck avionics solution, [41] [42] they also supplies the FMS-4200 flight management system (FMS) for the C909, which can also be seen on Mitsubishi CRJ550/700/900/1000 regional aircraft and the weather radar.
Cardom – the Soltam Systems recoil mortar system; Dragon Fire – a similar project by the US Marines, also known as Expeditionary Fire Support System (EFSS). M1064 mortar carrier – in use with the Army, based on the M113 tracked vehicle. XM1204 Non-Line-of-Sight Mortar, U.S. Army Future Combat Systems mortar carrier canceled in 2009
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.
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 .
In vector control, an AC induction or synchronous motor is controlled under all operating conditions like a separately excited DC motor. [21] That is, the AC motor behaves like a DC motor in which the field flux linkage and armature flux linkage created by the respective field and armature (or torque component) currents are orthogonally aligned such that, when torque is controlled, the field ...
