Abstract
Description
Die bisher bekannten einfachen Winglets haben zwar einen positi ven, relativ geringen Einfluß auf die Flugeigenschaften, das hier von mir vorgestellte wird den bislang bekannten in den positiven, nach stehend beschriebenen Eigenschaften um einiges überlegen sein.The simple winglets known so far have a positi ven, relatively little influence on the flight characteristics, that of here is presented to me in the positive, according to the previously known properties described above can be a lot superior.
Die von mir nachstehend vorgestellten Multiwinglets teilen die großen Randwirbel an den Endpunkten in mehrere kleine auf und reduziert daher die gesamte Masse der Wirbel.The multiwinglets I presented below share the big ones Edge vertebrae at the end points are broken up into several small ones hence the total mass of the vertebrae.
Es ist vorgesehen, die Einstellung der Multiwinglets je nach Größe und Geschwindigkeit und Größe des Objektes stufenlos in der senk rechten und waagerechten Ebene einzustellen. Es wird Aufgabe der Zukunft sein, diese Werte durch Windkanal, Messungen und prakti sche Versuche genau zu ermitteln.It is intended to adjust the multiwinglets depending on their size and speed and size of the object continuously in the lower right and horizontal level. It will be the job of Be future, these values through wind tunnel, measurements and practical attempts to determine exactly.
In einem von mir vor etwa 12 Jahren entwickelten Flugmodell wurden
diese Art Multiwinglets als Patent von mir eingereicht. Leider war
das zu dieser Zeit noch zu früh, niemand interessierte sich dafür und
ich habe den Antrag zurückgezogen. (Siehe Anlage)
Die Art des zu verwendeten Materials ist natürlich zwischen Groß
flugzeug und Segler absolut verschieden und kann erst durch prakti
sche Versuche festgelegt werden. Es ist zunächst geplant, den er
sten im jetzt vorgesehenen Motorsegler Kohlefaser zu verwenden.In a flight model that I developed about 12 years ago, I filed a patent for this type of multiwinglet. Unfortunately it was too early at that time, nobody was interested and I withdrew the application. (See Attachment)
The type of material used is of course completely different between large aircraft and gliders and can only be determined through practical trials. It is initially planned to use carbon fiber in the motor glider now provided.
Nachdem ich durch Bau eines Flugmodells vor 15 Jahren eine neue Version von Multiwinglets entwickelt und durch Flugversuche getestet habe, möchte ich sie jetzt für verschiedene Fluggeräte als Patent anmelden. After building a flight model 15 years ago, I got a new one Version of Multiwinglets developed and tested by flight tests I would now like to patent them for various aircraft Sign in.
Durch meine Bekanntschaft mit Herrn Dipl. Ing. Waibel, der für die Fa. Schleicher in Poppenhausen als Konstrukteur für deren Segler und Motorsegler verantwortlich ist, habe ich mit ihm vereinbart, daß er mir bei der praktischen Weiterentwicklung der Multiwinglets behilflich sein wird. Er wird die Multiwinglets in seinen Motorsegler einbauen und praktisch testen. Der Zeitpunkt dafür kann jedoch gegenwärtig noch nicht festgelegt werden. Die Ergebnisse der Flugeigenschaften werde ich Ihnen dann nachreichen.Thanks to my acquaintance with Dipl. Ing. Waibel, who works for Schleicher in Poppenhausen as a designer for their sailors and Motor glider is responsible, I agreed with him that he would give me help with the practical development of the Multiwinglets will be. He will install the multiwinglets in his motor glider and test it practically. However, the timing for this can be present not yet determined. The results of flight characteristics I'll give you later.
Die Funktion der Multiwinglets ist für alle nachstehend beschriebenen Geräte nahezu gleich und weicht nur mit geringfügigen Konstrukti onsmerkmalen voneinander ab, die Wirkungsweise ist nahezu immer die gleiche.The function of the multiwinglets is for all described below Devices almost the same and only give way with slight construction ons features, the mode of action is almost always the same.
Das Patent soll auch für die nachstehenden Fluggeräte
gelten, die hier noch im Einzelnen genau beschrieben wer
den:
The patent is also intended to apply to the following aircraft, which are described in detail here:
- 1. Flugzeuge und Ultraleichtflugzeuge aller Art1. Airplanes and microlights of all kinds
- 2. Hubschrauber aller Art2. All kinds of helicopters
- 3. Propeller aller Art3. All kinds of propellers
- 4. Flugdrachen und Gleitschirme aller Art4. Kites and paragliders of all kinds
-
5. Luftkissenfahrzeuge aller Art
sowie Modelle aller dieser obigen Arten für Modellbauer5.All types of hovercraft
as well as models of all of the above types for model builders
Alle obigen Bauteile werden während ihrer Arbeit von Luftwirbeln ver schiedener Größe heimgesucht, die störende Wirbelschleppen verur sachen. Weil diese je nach Gerät relativ große Luftwiderstände und höheren Kraftstoffverbrauch bewirken, soll dem durch die beantrag ten Multiwinglets entgegengewirkt werden.All of the above components are ver from air vortexes during their work of various sizes afflicted by the annoying wake stuff. Because, depending on the device, these have relatively large air resistances and This should result in higher fuel consumption through the application ten multiwinglets can be counteracted.
Das Patent würde für die jeweiligen Geräte den
nachfolgend beschriebenen Funktionszustand
bewirken. (bei Modellversuchen ermittelt)
The patent would bring about the functional state described below for the respective devices. (determined in model tests)
- a. Verbesserter Gleitwinkel durch geringeren Luftwiderstand, dadurcha. Improved glide angle due to lower air resistance, thereby
- b. Geringerer Kraftstoffverbrauch und größere Reichweiteb. Lower fuel consumption and greater range
- c. Verbesserter und stabiler Kurvenflug wie bei großen Vögelnc. Improved and stable cornering as with large birds
- d. Verringerter Bodeneffekt d. Reduced soil effect
- e. Stabiler Kurvenfluge. Stable cornering
- f. Größere Flugstabilität und größere Flugsicherheitf. Greater flight stability and greater flight safety
- g. Allgemein verbesserte Flug- und AbkippeigenschaftenG. Generally improved flight and tipping properties
Wenn man am Flughafen bei Regenwetter eine Boeing 747 (Jumbo) starten oder landen sieht kann man mit bloßem Auge die riesigen Wirbel erkennen, die bei beiden Tragflächenenden in Bodennähe entstehen und auch entsprechende Luftwirbelschleppen mit hohem Luftwiderstand. Durch die Aufteilung meiner Multiwinglets wird dieser Widerstand im mehrere kleine aufgeteilt und in der Gesamtmasse wesentlich verringert.If you have a Boeing 747 (Jumbo) at the airport in rainy weather Take off or land you can see the huge ones with the naked eye Identify vertebrae near the ground at both wing ends arise and also corresponding vortex drag with high Drag. By dividing my multiwinglets this becomes Resistance divided into several small ones and in the total mass significantly reduced.
Beobachtet man in der Natur oder im Fernsehen einen großen Vogel (z. B. Geier), der große Multiwinglets hat und diese beim Segelflug weit ausspreizt, kann man bereits eine große Flugstabilität genau beobachten.If you watch a big bird in nature or on TV (e.g. vulture), which has large multiwinglets and these when gliding spreading wide, you can already have great flight stability precisely observe.
Einzelheiten wie Schrauben und sonstige Befestigungsteile wurden in Beschreibung und Zeichnung weggelassen, weil es das ja bereits alles gibt. Außerdem würde dann der Überblick aus das Wesentliche gestört.Details such as screws and other fasteners were in Description and drawing omitted, because that's already it everything there. In addition, the overview would then focus on the essentials disturbed.
