Introduction 1936

The Henschel Hs 122 was a German army cooperation/reconnaissance aircraft of the mid-1930s, radial-engined and with a parasol wing. Though only pre-production variants entered service, the Hs 122 led on to the Hs 126 which was produced in large numbers.

Development[edit | edit source]

The Hs 122 was the Henschel company's second aircraft, its first, the Hs 121 not being intended for production. It was designed in response to a Reich Air Ministry call for a multi-role army co-operation aircraft to replace the ageing Heinkel He 46.

The design emerged as a single-engine two-seat parasol wing machine with a fixed undercarriage. The wing centre section was carried above the fuselage on a series of short struts and the swept outer sections were braced to the lower fuselage with V struts. The wings were built around two metal spars and had metal-covered leading edges and upper surfaces with fabric elsewhere. The fuselage was an elliptical metal monocoque, with a metal-structured tail also metal covered apart from fabric control surfaces. The tailplane was mounted about halfway up the fin, supported by a parallel pair of struts. The spatted mainwheels were each mounted on V struts to the fuselage. The cockpits were open, with the pilot sitting below a cut-out in the wing trailing edge and the second crew member in a separate cockpit aft.[1]

The first prototype, registered D-UBYN was powered, like several other German aircraft of the time including the Messerschmitt Bf 109 by a Rolls-Royce Kestrel V-12-cylinder water-cooled engine, but the next prototype (D-UBAV) had a 460 kW (610 hp) Siemens Sh 22B 9-cylinder supercharged radial.[1]

There were at least three prototypes, followed by a small number of pre-production Siemens-powered Hs 122B-0 aircraft which entered service in 1936. These were followed on the Henschel production lines at Schönefeld by the more powerful Hs 126.
