-the rotary engine was an early type of ‘internal-combustion engine’, usually designed with an ‘odd #’ of ‘cylinders’ per ‘row’ in a ‘radial configuration’, in which the ‘crankshaft’ remained ‘stationary’ in operation, with the entire ‘crankcase’ and its ‘attached cylinders’ rotating around it as a ‘unit’-
.
(its main application was in ‘aviation’, although it also saw use before its primary aviation role, in a few early ‘motorcycles’ + ‘automobiles’)
(this type of ‘engine’ was widely used as an alternative to ‘conventional inline engines’ (‘straight’ or ‘V’) during ‘world war 1’ and the years immediately preceding that conflict)
(it has been described as “a very efficient solution to the problems of (‘power output’ / ‘weight’ / ‘reliability’)”)
(by the ‘early 1920s’, however, the inherent limitations of this type of ‘engine’ had rendered it obsolete, with the ‘power output’ increasingly going into overcoming the ‘air-resistance’ of the ‘spinning engine itself’)
(the ‘rotating mass’ of the ‘engine’ also caused significant ‘gyroscopic precession’)
(depending on the type of ‘aircraft’, this produced ‘stability’ + ‘control’ problems, especially for ‘inexperienced pilots’)
.
(another factor in the demise of the ‘rotary’ was the fundamentally inefficient total-loss oiling system, caused by the need to ‘aspirate’ the ‘fuel/air mixture’ through the hollow ‘crankshaft’ + ‘crankcase’ along with the ‘lubricating medium’, as in a ‘2-stroke engine’)
