Klemm. Легкие самолеты
Следующим этапным проектом стал двухместный низкоплан Kl 35, прототип которого Kl 35a поднялся в воздух в 1935 году с мотором Hirth HM 60R мощностью 80 л.с. На втором прототипе Kl 35b установили мотор Hirth HM 504A-2 в 105 л.с.; аналогичные
двигатели стояли на первом серийном Kl 35B. Kl 35BW оснащался поплавковым шасси и мог собираться в "домашних" условиях. Kl 35 разных модификаций экспортировались в Чехословакию, Венгрию, Румынию. В Швеции такие самолеты строили по лицензии и использовали в ВВС.
В 1938 году появился улучшенный Kl 35D, предназначенный для первоначального обучения военных летчиков. Самолет строился массово.
Самолет Kl 106 со 100-сильным двигателем Hirth HM 500 был разработан на основе Kl 35D.

A NEW GERMAN TWO-SEATER
The Klemm Kl.35: An Open-cockpit Touring Aeroplane With Full Aerobatic Factors
SHOWN to the general public for the first time at the Milan Aero Show, the Klemm Kl.35 departs both in its general form and in the details of its structure from the machines which have made the name Klemm famous. It does, however, remain true to Dr. Klemm's original ideal of a low-wing cantilever monoplane, a type which he has done much to popularise, and which has now, more than ten years afterwards, come to be a very common type.
Changes in general design immediately noticeable are the downswept wing roots find the cantilever undercarriage. The reason for the former is probably that of obtaining "open" angles at the junction of the wing roots and the fuselage, thereby reducing the amount of interference without the use of large "fillets." Another advantage of the arrangement is that the ground angle of the machine is increased without increasing the length of the undercarriage legs. Thus it has become possible to adopt a cantilever type of leg of reasonably low weight. The leg, by the way, is designed for sinking speeds of as high as 9.2 ft./sec.
Structurally the Klemm Kl.35 is chiefly noteworthy for the fact that the fuselage is a steel tube girder of oval cross-section with fabric covering.
The two cockpits are arranged in tandem in the usual way, but it is claimed that the view is considerably improved by dropping the wing as previously described.
Large-span ailerons are fitted, but trailing-edge flaps are, apparently, not used. The only concession to Dame Fashion is to be found in the "tabs" on the elevator trailing edge, which take the place of a trimming tailplane. All flying controls are carried on ball bearings.
A Hirth H.M. 60 R engine of 70-80 h.p. is fitted in the prototype machine, but we are informed that the production model may have an engine of about 100 b.h.p.
The main data relating to the first model are as follows: wing area, 163 sq. ft.; weight empty, 870 lb.; disposable load, 605 lb.; loaded weight, 1,475 lb.; wing loading, 9 lb./sq.ft.; max. speed, 118 m.p.h.; cruising speed, 108 m.p.h.; landing speed, 45 m.p.h.; range, 500 miles; climb to 3,300 ft., 6.5 min.
A batch of production machines is to be laid down shortly at the Boblingen (Wurttemberg) works of Leichtflugzeugbau Klemm G.m.b.H. so that the machine should be on the market in a few months.

Kl 35D стал развитием Kl 35, отличался усиленным шасси (допускалась замена колес на поплавки или лыжи). Кроме того была предусмотрена возможность установки двигателя Hirth HM 60R меньшей мощности.
Downswept wing roots are the most noticeable innovation in the latest German Klemm.
THE LATEST KLEMM: The clean "frontage" of the new German Klemm Kl.35 (70-80 h.p. Hirth H.M. 60R. engine) is apparent in this view.

The Klemm is painted in the RLM Grey that was common to most trainers, but the yellow band around the fuselage, normally symbolizing an aircraft operating on the Russian Front, is somewhat of a mystery.

In the foreground of this general view are the Bucker and Klemm exhibits. The Fokker C11W seaplane is in the distance.
Herr Hellman Tolxis and Herr Ritsch, his passenger, who came over in a Klemm 35, are linguistically assisted by the ever-helpful Mr. R. L'E. Malone of Airwork.
Herr Clausen is being congratulated by Mrs. W. E. Davis, who entered the machine which finished third.
SUNSHADE SPECIAL. Built for the personal use of sports and glider pilot Wolf Hirth of Nabern/Teck, this Klemm Kl 35 Spezial (D-EDEX) is a single-seat cabin development of the open, tandem-seat, pre-war Kl 35D. In place of the standard 105-h.p. HM 504 in-line is a 160-h.p. HM 506. The Klemm Spezial was photographed at the 9th International Exposition, Venice, 16th-20th July.
