Adjective
medium-speed (comparative more medium-speed, superlative most medium-speed)
That operates, moves or takes place at a normal speed.
medium speed
Most medium-speed engines produced are four-stroke machines, however there are some two-stroke medium-speed engines such as by EMD ( Electro-Motive Diesel ), and the Fairbanks Morse OP ( Opposed-piston engine ) type. Source: Internet
Due to the lower rotational speed of slow- and medium-speed engines, there is more time for combustion during the power stroke of the cycle, allowing the use of slower-burning fuels than high-speed engines. Source: Internet
Typical cylinder bore size for medium-speed engines ranges from 20 cm to 50 cm, and engine configurations typically are offered ranging from in-line 4-cylinder units to V-configuration 20-cylinder units. Source: Internet
Most larger medium-speed engines are started with compressed air direct on pistons, using an air distributor, as opposed to a pneumatic starting motor acting on the flywheel, which tends to be used for smaller engines. Source: Internet
Slow-speed engines are predominantly large two-stroke crosshead engines, hence very different from high- and medium-speed engines. Source: Internet
The 40 by 80 Foot Wind Tunnel is primarily used for determining the low- and medium-speed aerodynamic characteristics of high-performance aircraft, rotorcraft, and fixed wing, powered-lift V/STOL aircraft. Source: Internet
