Postwar
By the time the war ended, the rotary engine had become obsolete, and it disappeared from use quite quickly. The British Royal Air Force probably used rotary engines for longer than most other operators - the RAF's standard post-war fighter, the Sopwith Snipe, used the Bentley BR2 rotary, and the standard trainer, the Avro 504K, had a universal mounting to allow the use of several different types of low powered rotary, of which there was a large surplus supply. However, the cheapness of war-surplus engines had to be balanced against their poor fuel efficiency and the operating expense of their total loss lubrication system.
By the mid-1920s, rotaries had been more or less completely displaced even in British service, largely by the new generation of air-cooled "stationary" radials.

Famous quotes containing the word postwar:
“Fashions change, and with the new psychoanalytical perspective of the postwar period [WWII], child rearing became enshrined as the special responsibility of mothers ... any shortcoming in adult life was now seen as rooted in the failure of mothering during childhood.”
—Sylvia Ann Hewitt (20th century)
