The Ryan PT-22 Recruit, the main military version of the Ryan ST, is a military trainer aircraft used by the United States Army Air Corps and its successor, the United States Army Air Forces for primary pilot training.
Design and development
The PT-22's fuselage is a simple monocoque structure, with thick gauge alclad skin. The wings feature spruce spars, aluminum alloy ribs, steel compression members, with aircraft fabric covering aft to the trailing edge and aluminum alloy sheet covering from the leading edge to the spar.[1] The wings have 4° 10' of sweep back, 3° of incidence and 4° 30' dihedral.[2]
The PT-22 fuel system consists of a single tank mounted forward of the front cockpit. Fuel is gravity fed to the carburetor. The oil system is a dry-sump type, with all oil stored in a tank located on the front side of the firewall in the upper section of the fuselage. The wing flaps are mechanically operated from a lever located on the left side of each cockpit. Adjustable elevator trim is provided via an elevator trim tab controllable from a handwheel mounted on the left side of each cockpit. In its original configuration, the aircraft was not equipped with an electrical system. Hydraulic brakes are provided for each wheel, controllable via the rudder pedals in each cockpit.[3]
In order to simplify maintenance, the wheel spats and landing gear fairings were deleted in the production examples
Operational history
The PT-22 was developed in 1941 from the civilian Ryan ST series. The earlier PT-20 and PT-21 were the military production versions of the Ryan ST-3 with a total of 100 built. The PT-22 was the United States Army Air Corps' first purpose built monoplane trainer. The rapid expansion of wartime aircrew training required new trainers, and the Ryan PT-22 was ordered in large numbers.[4] Named the "Recruit", it entered operational service with the U.S. Orders also were placed by the Netherlands, but were never realized as the nation capitulated to Axis forces. The small order of 25 ST-3s was redirected to the United States and redesignated as the PT-22A. Another order also came from the U.S. Navy for 100 examples. The PT series was in heavy use throughout the war years with both military and civil schools, but with the end of the war, was retired from the USAAF.[5]
The Ryan PT-22 remains a popular World War II collector aircraft.
