Abstract
Description
Diese Erfindung bezieht sich auf Flugzeugturbinen an allen Flugzeugtypen im Zivil- sowie Militärflugwesen.This invention relates to aircraft turbines on all types of aircraft in civil and military aviation.
Flugstrahlturbinen kommen in verschiedenen Typen als Flugzeugantrieb an verschiedenen Flugzeugtypen vor.Air jet turbines come in various types as aircraft propulsion on various types of aircraft.
Es gibt bislang keine Vorrichtung, die einen Absturz eines Turbinenflugzeuges durch Flugtiere verhindert.There is currently no device that could crash a turbine plane prevented by flying animals.
Im deutschsprachigen Raum und im europäischen Patentwesen gibt es keine derartige Erfindung. Die Strahltriebwerke/Turbinen saugen die Flugtiere an und erwirken so Abstürze. In den vergangenen Jahren wurden sehr oft Abstürze von Turbinenflugzeugen, die durch Flugtiere verursacht werden, in allen Medien bekanntgegeben.There are none in German-speaking countries and in European patent systems such invention. The jet engines / turbines suck in the flying animals and cause crashes. In the past few years, very often Turbine aircraft crashes caused by flying animals announced in all media.
Durch den Vorsatz einer Schutzvorrichtung (Fig. 1/2/3/4) vor den Turbinen könnten Abstürze verhindert werden!A protective device ( Fig. 1/2/3/4) in front of the turbines could prevent falls!
Gegenstand der vorliegenden Erfindung ist eine Schutzvorrichtung bestehend aus einem Ring (Fig. 3/4/5/6) mit Maschennetz aus starkem Draht. Das Maschengewebe (Fig. 5/6) soll die Flugtiere abhalten und somit ein Ansaugen verhindern.The present invention relates to a protective device consisting of a ring ( Fig. 3/4/5/6) with a mesh of strong wire. The mesh fabric ( Fig. 5/6) should keep the flying animals and thus prevent suction.
Diese Erfindung weist nur Vorteile auf. So lassen sich diese Schutzvorrichtungen/ Schutzkörbe an jedem Turbinenflugzeug nachträglich anbringen, jederzeit auswechseln oder nachrüsten (Wartung).This invention has only advantages. This is how these protective devices / Attach protective cages to every turbine aircraft at any time replace or retrofit (maintenance).
Erfindungsgemäß wird der Schutz dadurch erreicht, daß die Schutzvorrichtung in kegelförmiger oder konvexer erhabener Form (Fig. 1/2/3/4) die Flugtiere vor einem Ansaugen bewahrt, und ein Flugzeugabsturz vermieden wird. Ein weiterer Vorteil liegt in der Tatsache, daß diese Ringsiebe (2) mit starkem Maschendraht (Fig. 5) jederzeit ausgewechselt und erneuert werden können. Eine Herstellung ist unkompliziert, einfach und ökonomisch äußerst vorteilhaft, aufgrund des einfachen Aufbaues und der einfachen Befestigung (wahlweise in Dreipunkt- oder Vierpunktaufhängung [Fig. 5/6]) durch Öse (3) und Spannhaken (4).According to the invention, the protection is achieved in that the protective device in conical or convex raised form ( Fig. 1/2/3/4) prevents the flying animals from being sucked in and an aircraft crash is avoided. Another advantage lies in the fact that these ring sieves ( 2 ) with strong wire mesh ( Fig. 5) can be replaced and renewed at any time. Manufacturing is uncomplicated, simple and extremely economical, due to the simple structure and the simple fastening (optionally in three-point or four-point suspension [ Fig. 5/6]) by means of an eyelet ( 3 ) and tensioning hook ( 4 ).
Die Drahtnetze (Fig. 1/2) sollten jeweils mit einem der (gewählten) Form entsprechenden Skelett (Fig. 5/6) als Versteifung/Verfestigung (zur Erhöhung der Sicherheit und Haltbarkeit) eingesetzt werden. Im folgenden wird diese Erfindung anhand eines Beispiels mit Bezug auf die beiliegenden Zeichnungen (Fig. 1 . . . 9) näher erläutert. Die Fig. 1 und 2 zeigen die erfindungsgemäße Schutzvorrichtung in Seitenansicht, in Aufhängung an Tragflächen. Die Maschensiebe/Drahtgewebe (Fig. 1/2/3/4) sind in kegelförmiger oder konvexer Form (Fig. 3/4), damit die Flugtiere noch vor dem Turbineneintritt aufgefangen werden und die Vorsätze selbst genügend Widerstand leisten (Haltbarkeit, Festigkeit). The wire nets ( Fig. 1/2) should each be used with a skeleton ( Fig. 5/6) corresponding to the (selected) shape as stiffening / strengthening (to increase safety and durability). In the following, this invention is explained in more detail using an example with reference to the accompanying drawings ( Fig. 1 ... 9). Figs. 1 and 2 show the protection device according to the invention in side view, in suspension at wings. The mesh screens / wire mesh ( Fig. 1/2/3/4) are in a conical or convex shape ( Fig. 3/4), so that the flying animals are caught before the turbine enters and the attachments themselves provide sufficient resistance (durability, strength) .
Als Strukturelemente wurden sogenannte Skelette (Fig. 5, 6) zur Verfestigung und Haltbarkeit gedacht.So-called skeletons ( Fig. 5, 6) were considered as structural elements for strengthening and durability.
Anbringung der Schutzvorsätze:
An jeder Turbine soll eine Öse (3) sein in die der Ringhaken (1) (oder
Ösenhaken genannt) einfach eingeschoben und damit eingeklemmt wird.
Dann werden die Spannhaken (4), die an der Turbine befestigt sind, über den
Rand (2) des Ringes (Fig. 7, 8) gespannt.Attaching the protective attachments:
There should be an eyelet ( 3 ) on each turbine into which the ring hook ( 1 ) (or called the eyelet hook) is simply inserted and thus clamped. Then the clamping hooks ( 4 ), which are attached to the turbine, are stretched over the edge ( 2 ) of the ring ( Fig. 7, 8).
Eine nachträgliche Anbringung der Schutzkörbe/Schutzvorrichtungen, die Wartung und Erneuerung, ist also unkompliziert. Diese Erfindung ist kostengünstig, einfach und wichtig, so daß ein Anbringen dieser Schutzvorrichtungen an alle Turbinenflugzeuge im Zivil- und Militärflugwesen international erzwungen werden müßte!A subsequent attachment of the protective baskets / protective devices that Maintenance and renewal is therefore straightforward. This invention is inexpensive simple and important, so attaching these guards to all turbine aircraft in civil and military aviation should be enforced internationally!
