Van Norman #12 milling machine. The Van Norman Machine Tool Company was an American machine tool builder from late in the 19th century until the mid-1980s. The company was based in Springfield, Massachusetts, USA. Its main areas of focus were milling machines and grinding machines. The company was acquired by Universal American Corporation ...
Swashplates can be used in an axial engine in place of a crankshaft to translate the motion of a piston into rotary motion. Such engines are the only variation of the cam engine to have any success. Internal combustion engines and Stirling engines have been built using this mechanism. Duke Engines has been working on such a platform since 1993. [3]
He mounted this machine on an army surplus vehicle chassis. A blade mounted on the machine shaved the ice, which then received a thin layer of water to create a smooth sheet of ice. The prototype had a tank that held the ice shavings, which it carried to the tank via a conveyor belt. This machine was powered by a Jeep engine and transmission ...
An engine crane (also referred as engine hoist [1]) is a common repair tool used in vehicle repair shops to remove or install gasoline or diesel engines in small and crowded vehicle engine compartments. It uses a heavy cantilevered support structure to hold the engine in mid-air so that the mechanic can carefully connect or disconnect fragile ...
The higher the loading, the more power needed to maintain rotor speed. [3] A low disk loading is a direct indicator of high lift thrust efficiency. [4] Increasing the weight of a helicopter increases disk loading. For a given weight, a helicopter with shorter rotors will have higher disk loading, and will require more engine power to hover.
The term recreational vehicle (RV) is often used as a broad category of motor vehicles and trailers which include living quarters for designed temporary accommodation. [1] Types of RVs include motorhomes, campervans, caravans (also known as travel trailers and camper trailers), fifth-wheel trailers, popup campers, truck campers and Park Model RVs.
Rotor solidity is a function of the aspect ratio and number of blades in the rotor and is widely used as a parameter for ensuring geometric similarity in rotorcraft experiments. It provides a measure of how close a lifting rotor system is to an ideal actuator disk in momentum theory .
Quasiturbine QT-AC. The Quasiturbine or Qurbine engine is a proposed pistonless rotary engine using a rhomboidal rotor whose sides are hinged at the vertices. [1] The volume enclosed between the sides of the rotor and the rotor casing provide compression and expansion in a fashion similar to the more familiar Wankel engine, but the hinging at the edges allows the volume ratio to increase.
