Abstract

The multi cylindered model air craft engine consists of two or more series produced two stroke engines. Each engine has its own crank shaft which carries a gear wheel. The individual gear wheels mesh with a single gear wheel fixed to a central drive shaft. The central drive shaft (1) is mounted in bearings (2) carried by a crank case housing (3). The air screw (4) revolution speed can be selected according to the gear wheel ratio (5). The individual crank shafts (6) are supported in bearings (7) mounted in the crank case housing. The individual carburettors are retained.

Betr.: Mehrzylinder Zweitakt - Sternmotor für Flugmodelle.Re: multi-cylinder two-stroke radial engine for model aircraft.

Für Flugmodelle werden als Antrieb Einzylinder-Kolbenmotore, die im Zweitakt System arbeiten, verwendet. ,Single-cylinder piston engines are used as the drive for model aircraft, that work in the two-stroke system. ,

Sie sind erhältlich, für einen Hubraum von 0,8 bis 25 cm . Bei einer Leistung von 0,08 bis 2,5 PS.They are available for a displacement from 0.8 to 25 cm. With an output of 0.08 to 2.5 hp.

Ein von mir erdachtes System ermöglicht es, aus allen Serienteilen dieser Motore, außer dem Kurbelgehäuse, einen Mehrzylinder-Sternmotor herzustellen.A system devised by me makes it possible to use all series parts of these engines, apart from the crankcase, a multi-cylinder radial engine to manufacture.

Auch kann die Drehzahl der luftschraube entsprechend dem Durchmesser und der Größe des Modelles angepaßt werden.The speed of the propeller can also be adjusted according to the diameter and size of the model.

Das von mir erdachte System ist folgendes:The system I devised is the following:

Eine in der Mitte des Kurbelgehäuses zentral gelagerte Vifelle erhält an einer Seite ein Zahnrad, in welches die Zahnräder, die auf den einzelnen Kurbelwellen montiert sind, eingreifen.A vifelle centrally mounted in the middle of the crankcase receives a gear on one side, in which the gear wheels, which are mounted on the individual crankshafts, intervention.

Je nach Zahnrad-Übersetzungsverhältnis kann die Drehzahl der Zentralwelle ( gleich Luft-Schraubenwelle ) gewählt werden.Depending on the gear ratio, the speed of the central shaft (equal to the air screw shaft) can be selected.

Der Sternmotor hat ein Kurbelgehäuse, in dem zwei, drei oder entsprechend mehr Kurbelwellen eingebaut sind.The radial engine has a crankcase in which two, three or more crankshafts are installed.

Das Gehäuse wird von einer Seite so ausgebohrt, daß die Kurbelwellen um die Zentralwelle gelagert sind.The housing is drilled out from one side so that the crankshafts are supported around the central shaft.

Jeder Zylinder hat somit sein eigenes Kurbelgehäuse und seine eigene Kurbelwelle.Each cylinder thus has its own crankcase and its own crankshaft.

Es kann der Vergaser ( auch Serienherstellung ) für jeden einzelnen Zylinder beibehalten werden.The carburetor (also series production) can be retained for each individual cylinder.
