T-72K: Command version of the T-72 "Ural" with an additional R-130M radio. Company command versions were fitted with two additional R-123M/R-173 radios and also carried a 10 m telescopic mast. Battalion and regiment command versions were fitted with two additional R-123M/R-173 radios and the R-130M that used the 10 m mast when it was erected.
For a diesel at its introduction date of 1951, the engine operated at relatively high speed, up to 1,800 rpm. This was assisted by a viscous torsion damper at the opposite end to the flywheel. [ 1 ] High rotational speed made the engine an attractive choice in the developing market for small diesel-hydraulic locomotives .
The L stands for ledning (command or leadership). The Strb 90 KompL is a plain Strb 90 H in which portable computer and communications equipment have been installed, allowing it to temporarily provide company-level command and control. Electrical power is provided by a rather loud portable generator installed on the deck.
The key feature of the Ward Leonard control system is the ability to smoothly vary the speed of a DC motor, including reversing it, by controlling the field and hence the output voltage of a DC generator, as well as the field of the motor itself. As the speed of a DC motor is dictated by the supplied voltage, this gives simple speed control.
Constant speed drive for Boeing 727, made by Sundstrand Corporation. A constant speed drive (CSD) also known as a constant speed generator, is a type of transmission that takes an input shaft rotating at a wide range of speeds, delivering this power to an output shaft that rotates at a constant speed, despite the varying input.
Old Buda 8-cylinder Diesel engine. Buda-Lanova engines were also used by the Whitcomb Locomotive Works of Rochelle IL. Two Buda-Lanova model DCS 1879 6 cylinder supercharged Diesel engines (6.75 bore x 8.75 stroke, 325 hp @ 1,200 rpm) were installed in both 65-DE-14a and 65-DE-19a Diesel electric centercab locomotives that were purchased by the Army and shipped over to Africa and Europe during ...

The rotor of a turbo generator is a non-salient pole type usually with two poles. [5] The normal speed of a turbo generator is 1500 or 3000 rpm with four or two poles at 50 Hz (1800 or 3600 rpm with four or two poles at 60 Hz). The rotating parts of a turbo generator are subjected to high mechanical stresses because of the high operation speed.
