The Model V was among the early [2] electromechanical [3] general purpose computers, [4] [5] [6] designed by George Stibitz and built by Bell Telephone Laboratories, operational in 1946. Only two machines were built: first one was installed at National Advisory Committee for Aeronautics (NACA, later NASA), the second (1947) at the US Army’s ...
The two-stage valve-lift function is performed by electro-hydraulically operated switchable tappets. Each of these 12 tappets consists of concentric lifters which can be locked together by means of a pin. The inner lifter is actuated by a small cam lobe, while the outer ring element is moved by a pair of larger-profile lobes.
The Red Army adopted the V-2 engine in the same year in three modifications: the V-2 (500 hp (370 kW)), the V-2K (600 hp (450 kW)) for the KV line of tanks and the V-2V (375 hp (280 kW)). [ 1 ] Near the end of the 20th century, the V-2 was fitted with more modern modifications by the chief designer of the head design bureau for the Chelyabinsk ...

In 1956 the Superior Aircraft Company bought the assets of Culver and put the Model V back into production as the Superior Satellite. The main difference was the use of a 95 hp Continental engine which increased the cruise speed to 130 mph (209 km/h). Only a prototype and five production aircraft were built.
A modified variant of the V, the F, was the first aircraft to fly with the new Liberty L-12 engine that would find widespread use in the latter part of World War One.The model F in turn led to the "Reconnaissance", an intended production variant of the F, which in turn evolved into the LWF model G, although none of these would see large scale production.
SOHC design (for a 1973 Triumph Dolomite Sprint) . The oldest configuration of overhead camshaft engine is the single overhead camshaft (SOHC) design. [1] A SOHC engine has one camshaft per bank of cylinders, therefore a straight engine has a total of one camshaft and a V engine or flat engine has a total of two camshafts (one for each cylinder bank).
The V-model is a graphical representation of a systems development lifecycle.It is used to produce rigorous development lifecycle models and project management models. The V-model falls into three broad categories, the German V-Modell, a general testing model, and the US government standard.
