The Klemm Kl 151 was a four-seat aircraft designed by Hanns Klemm and his head of design, Carl Bucher , which was built in wood by Leichtflugzeugbau Klemm GmbH in the early 1940s . You should from congestion material aluminum manufactured Messerschmitt Bf 108 Taifun replace.

history

During a visit to the Reich Aviation Ministry (RLM) in 1940, Klemm and Carl Bucher received an order from General Aircraft Master Ernst Udet to start work on the four-seater in wood as quickly as possible, with the above-mentioned aim. One of the requirements was that the manually retractable landing gear of the Bf 108 should also be used for the new aircraft. However, this caused considerable difficulties in the assembly of the clamping wing, which were eventually circumvented by initially providing a fixed undercarriage for testing. In order to speed up the completion, both the wings and the fuselage were manufactured on the cores from the Kl 107 using the clamping partial shell construction. Since the fuselage was too short, Bucher lengthened it at the rear with an attached, welded and sheet steel-clad tubular steel frame that also accommodated the tail wheel. The wings had to be extended inwards at the roots and pulled forward in the nose area to accommodate the fuel tanks that had to give way to the two rear seats.

The chief pilot Karl Voy flew for the first time in Böblingen on September 10, 1942 with the Kl 151 V1 that was created in this way, which had received the TB + QK code . The aircraft was powered by an Argus As 10 P engine with 240 hp. The planned further development Kl 151 B, for which an Argus As 410 with 355 hp was intended, was no longer built. On February 19, 1943, the V1 was transferred to the DVL in Berlin-Adlershof for sample testing, which was successfully completed on March 1. The rigid landing gear had made the relevant Luftwaffe people thoughtful when they thought of the difficulties the landing gear of the Bf 108 had to deal with on the poor field airfields in the east. Therefore, in addition to the version with the retractable landing gear, a second one with a fixed landing gear was required. Instead of the previously used three-legged landing gear , the V1 now has powerful Y-shaped handlebars welded together from two steel half-shells to guide the suspension struts. The further endurance testing was thus continued. The plane was also used by the factory as a touring machine until it fell victim to bombs in July 1944.

The RLM had meanwhile given the further development and construction of the V2 as well as a possible series to the Czech company Zlín . A solution had been found for the retractable landing gear. The aircraft was never fully built.

After the war, a resumption of the class project was planned 151 by clamping, but the decision then fell in favor of the 107 A class of.
