Histoire résumée | The Aachen Team likewise reappeared at the Rhön meeting 1929 after an interval of some years of inactivity The Aachen Aeronautical Union's practice glider "M 1" of strutted wing type, had been constructed by Dipl.-Engineer Mayer with the object of producing a practice glider, of simple type but at the same time with good soaring qualities, as an improvement on the "Prüfling". The wing is of two-spar construction ; it is built in three sections, and throughout its span is of equal thickness and has the same wing-section (Gottingen 535). The middle portion lies upon the upper border of the body, and is supported by V struts at the points of junction with the outer portions. Thus the struts are held on by the same attachments as those which serve for the junctions with the outer wing portions. L'Akaflieg Karlsruhe est apparu dans les années 1930 avec son planeur simple Karlsruhe, qui était la réplique (éventuellement légèrement modifiée) du MIa par Hermann Mayer d'Aix-la-Chapelle, que le Karlsruher avait rencontré sur le Rhön. Mayer a fourni les plans et a également contribué aux conseils et à l'action pendant la construction, qui a lieu dans la saison hivernale de 1929/30 à juin 1930. The body has a hexagonal cross-section. It is covered with plywood as far back as the rear spar and from there onwards with fabric. At the rear it terminates in a vertical edge, which is continued upwards into the vertical stabilising fin. The rudder is rectangular, and narrow in width. The horizontal stabilising fin is fixed to both sides of the body and supported underneath by a strut to each side. The elevator is rectangular with a portion cut away for the rudder. The performance of this aircraft was very satisfactory, so that the machine, piloted by its constructor Mayer, was able to carry out some very notable flights during the meeting. The Aachen team thereby performed a valuable service for the further development of the school sailplane type. | ||||||
