Abstract
Description
Die Erfindung betrifft ein senkrecht startendes und landendes Propellerflugzeug, das keine vorbereitete Start- und Landebahn benötigt.The invention relates to a vertical takeoff and landing Propeller plane that has no prepared runway needed.
Bekannt sind einmotorige Propellerflugzeuge, die den Propeller vorn haben, und senkrecht auf dem Heck starten und landen. Bekannt sind auch zwei oder viermotorige Flugzeuge, die ihre Motore an Tragflächen oder Auslegern, seitlich vom Rumpf haben. Bei diesen Flugzeugen werden die Triebwerke samt Propellern zum Senkrecht- bzw. Waagrechtflug, um jeweils neunzig Grad geschwenkt. Die Entwicklung der Heckstarter wurde bereits nach der Erprobung der ersten Muster wieder eingestellt. Die auftretenden flugtechnischen Probleme erwiesen sich als zu schwerwiegend. Bei der zweiten Art von Senkrecht startern, wirft das Schwenken von ganzen Triebwerken Probleme auf. Außerdem werden die Tragflächen, an denen die Triebwerke befestigt sind, großen Belastungen ausgesetzt. Bisher wurde noch keiner der vorgenannten Senkrechtstarter zur Serienreife entwickelt.Single-engine propeller aircraft are known, which Have propellers in front, and start vertically on the stern and land. Also known are two or four engine aircraft, which their engines on wings or booms, from the side Have fuselage. The engines on these aircraft including propellers for vertical or horizontal flight, respectively pivoted ninety degrees. The development of the rear starter was already back after testing the first samples set. The flight problems encountered proved turned out to be too serious. The second type of perpendicular starter, the swiveling of entire engines poses problems on. In addition, the wings on which the engines are attached, exposed to large loads. So far none of the above-mentioned high-flyers ready for series production developed.
Der Erfindung liegt die Aufgabe zugrunde, eine praktikable Lösung für ein senkrecht startendes und landendes Propellerflugzeug zu finden. Diese Aufgabe wird erfindungs mäßig dadurch gelöst, daß das Flugzeug am vorderen Rumpfende einen Zugpropeller, und am hinteren Rumpfende einen Schub propeller hat. Die Propeller sind, jeder für sich, in Propeller trägern gelagert, die schwenkbar am Rumpf befestigt sind, und zwar so, daß der vordere Propeller, für Senkrechtstart und Landung um neunzig Grad von der Flugzeuglängsachse nach oben geschwenkt werden kann, und der hintere um neunzig Grad nach unten. Der Antrieb der Propeller erfolgt dadurch, daß durch die Lagerachse des Propellerträgers die Antriebswelle geführt wird, die über Kegelzahnräder vom Motor angetrieben wird, und, ebenfalls über Kegelzahnräder, den Propeller antreibt. Das Flugzeug kann mit zwei Motoren ausgestattet sein, so daß sich je einer vor und hinter der Kabine befindet, oder auch mit ein oder zwei Motoren über oder unter der Kabine. Beim Antrieb durch zwei Motore, ist das Flugzeug so eingerichtet, daß im Falle des Ausfalls eines Motors bei Start oder Landung, der funktionierende Motor den Antrieb beider Propeller übernimmt. Auf der Lagerachse des Propellerträgers befindet sich ein Schneckenrad, in das eine im Rumpf befindliche Schnecke ein greift, die von einem Elektromotor angetrieben wird, wodurch der Propellerträger mit Propeller geschwenkt werden kann. Gegenüber anderen Senkrechtstartern dürfte der Vorteil hauptsächlich in der höheren Geschwindigkeit und der größeren Reichweite liegen. Daß Flugzeuge mit einer solchen Triebwerks- und Propelleranordnung sehr gute Flugeigenschaften haben können, beweist die Dornier 335, das schnellste Propellerflug zeug des zweiten Weltkriegs.The invention has for its object a practical solution for a vertical take-off and landing Find propeller plane. This task is fiction moderately solved in that the aircraft at the front end of the fuselage a train propeller, and a thrust at the rear end of the fuselage propeller. The propellers are, each individually, in propellers mounted on supports that are pivotally attached to the fuselage, in such a way that the front propeller for vertical takeoff and Landing ninety degrees up from the aircraft's long axis can be pivoted, and the rear by ninety degrees below. The propellers are driven by the bearing axis of the propeller carrier guided the drive shaft which is driven by the motor via bevel gears, and, also via bevel gears, which drives the propeller. The Airplane can be equipped with two engines, so that one in front of and behind the cabin, or with one or two engines above or below the cabin. With the drive with two engines, the aircraft is set up in such a way that In the event of an engine failure at take-off or landing, the working motor takes over the propulsion of both propellers. There is a on the bearing axis of the propeller carrier Worm wheel into which a snail located in the fuselage enters engages, which is driven by an electric motor, causing the propeller carrier can be swiveled with the propeller. Compared to other high-flyers, the advantage is likely mainly in the higher speed and the larger Range. That aircraft with such an engine and propeller arrangement have very good flight characteristics can prove, the Dornier 335, the fastest propeller flight witness of the Second World War.

Antriebswelle 4 kommt vom Motor und treibt über Kegelzahnrad 5+6 die durch den Lagerzapfen 7 des Propellerträgers 2 führende Welle 8, die wiederum über Kegelzahnrad 9+10 den Propeller 3 antreibt. Lagerzapfen 11 des Propellerträgers 2 ist mit dem Schneckenzahnrad 12 versehen, in das die im Rumpf befestigte Schnecke 13 eingreift, angetrieben vom Elektro motor 14, wodurch der Propeller geschwenkt werden kann. 1 is the fuselage in top view, 2 the propeller carrier with the propeller 3 . Drive shaft 4 comes from the motor and drives the bevel gear 5 + 6 through the bearing journal 7 of the propeller carrier 2 leading shaft 8 , which in turn drives the propeller 3 via bevel gear 9 + 10 . Bearing pin 11 of the propeller carrier 2 is provided with the worm gear 12 , in which the worm 13 fixed in the fuselage engages, driven by the electric motor 14 , whereby the propeller can be pivoted.
