The Junkers T 19, originally designated the J 19, was a German-designed, single-engine aircraft from the early 1920s featuring an all-metal parasol wing and seating for two or three occupants. Created for both training and touring purposes, its high manufacturing expenses restricted commercial appeal, resulting in only three units produced; one of these was later adapted as a platform for engine testing.
Design and development
As the initial model in a trio of Junkers aircraft aimed at private users, the T 19 employed pioneering all-metal construction with a duralumin tubular framework sheathed in corrugated metal panels. However, these advanced materials and methods led to production costs surpassing those typical of fabric-covered planes, which limited its market penetration.
The aircraft’s cantilever parasol wing consisted of a constant chord center section combined with tapered outer panels, equipped with broad-chord ailerons that extended beyond the trailing edge. The wing was supported by four pairs of struts—both V-shaped and inverted V-shaped—linking it to the upper fuselage longerons.
Its fuselage was tapered with flat sides and featured an elongated open cockpit stretching from the front to the rear edge of the wing. The pilot occupied the forward position behind the engine, while one or two passengers sat behind, accessible through a door on the starboard side. Mounted atop the fuselage, the tailplane included elevators with horn balances; a triangular fin with a straight-edged rudder extended below the fuselage between elevator cutouts, creating a pointed vertical silhouette. The main landing gear incorporated shock-absorbing legs attached to upper fuselage longerons, forward bracing struts beneath the engine compartment, and wheels connected by a hinged axle affixed to the lower fuselage.
Operational history
The T 19's maiden flight occurred on 14 July 1922, powered by a Siemens-Halske Sh 4 five-cylinder radial engine delivering 55 hp (41 kW). Subsequently, two additional T 19s were built: one equipped with a seven-cylinder Siemens-Halske Sh 5 producing 77 hp (57 kW), and another powered by a nine-cylinder Siemens-Halske Sh 12 generating 110 hp (82 kW). The second aircraft was utilized as an engine test platform, notably flying with Junkers' first air-cooled six-cylinder inline petrol engine—the 75 hp (56 kW) L1 introduced in 1921. It also operated using a 1926 Armstrong Siddeley Genet engine. The third T 19 found its way to India through sale.
