Abstract
Description
Flugzeuge werden heutzutage vorwiegend mit Düsenantrieb konstruiert, außer kleinen Sportflugzeugen mit Benzinmotor und kleinen Regionalflugzeugen mit Turboprop-Antrieb. Die in Sportflugzeugen verwendeten Benzinmotoren sind mehr als dreißig Jahre alte Konstruktionen und absolut nicht mehr Stand der Technik. Bei den Turboprops sind Neuentwicklungen ebenfalls Mangelware, da kleinere Düsentriebwerke sie nach und nach verdrängen.Aircrafts are nowadays mainly designed with jet propulsion, except small ones Sports aircraft with gasoline engine and small regional aircraft with Turboprop engine. The gasoline engines used in sports aircraft are more than thirty Years old constructions and absolutely no longer state of the art. In the turboprops new developments are also in short supply, since smaller jet engines gradually displace them.
Seit Jahren gibt es Versuche, Dieselmotoren wieder im Flugzeugbau zu etablieren, um an die Tradition aus der Zeit vor dem zweiten Weltkrieg anzuknüpfen. Obwohl sich einiges getan hat (z.B. der Zoche-Diesel), gibt es noch kein Serienflugzeug, das ab Werk mit Dieselmotorantrieb ausgerüstet wird. Nur zur Nachrüstung sind bereits Motoren verfügbar.since Years there are attempts to return diesel engines in aircraft too Establish to the tradition of the time before World War II to tie. Although a lot has happened (for example, the Zoche diesel), there are still No production aircraft equipped with diesel engine drive ex works. Only for retrofitting Engines are already available.
Um dies zu ändern habe ich einen komplett neuen Ansatz sowohl beim Motor als auch beim Antriebskonzept gewählt.Around to change this I have a completely new approach both on the engine as well chosen for the drive concept.
Der Circular-Aero-Diesel in seiner Ausführung als 8-Zylinder, 16-Zylinder, 32-Zylinder oder 64-Zylinder zeichnet sich durch das beste Gewicht/Leistungsverhältnis, sehr kompakte Abmessungen mit extrem kleiner Stirnfläche, hohe Drehzahl, einfache Bauweise und vibrationsarmen Lauf aus. Der 8-Zylindermotor ist jederzeit geeignet, die gebräuchlichen Benzinmotoren in Sportflugzeugen zu ersetzen und statt diesen eingebaut zu werden. Mit Leistungen von 100 – 800 kW bleiben keine Wünsche offen. Er kann wahlweise mit Dieselkraftstoff oder Kerosin betrieben werden und schluckt weniger als die Hälfte an Sprit, bei höherer Leistung und niedrigerem Gewicht.Of the Circular Aero-Diesel in its design as 8-cylinder, 16-cylinder, 32-cylinder or 64-cylinder is characterized by the best weight / performance ratio, very compact dimensions with extremely small face, high speed, simple Construction and low-vibration run out. The 8-cylinder engine is always available suitable, the common ones To replace gasoline engines in sports aircraft and installed instead to become. With outputs of 100 - 800 kW nothing is left to be desired. It can be operated with either diesel fuel or kerosene and swallows less than half at fuel, at higher Performance and lower weight.
Für den Einsatz in Großflugzeugen ist jedoch ein anderes Konzept nötig, um mit dem Düsenantrieb konkurrieren zu können, da mit Propellern keine vergleichbaren Geschwindigkeiten erreicht werden können, weil deren Größe nicht beliebig gesteigert werden kann. Es muss also statt des Propellers eine andere Form der Beschleunigung der Luft verwendet werden. Dafür bietet sich der Axiallüfter an. Er bringt mehr Druck, kann fast beliebig vergrößert werden (Nicht im Durchmesser, aber in der Länge.) und er kann in die Tragflächen eingebaut werden.For use in large aircraft However, another concept is needed to compete with the jet engine to be able to because with propellers no comparable speeds achieved can be because their size is not can be increased arbitrarily. So it has to be instead of the propeller another form of acceleration of the air can be used. For that offers the axial fan at. He brings more pressure, can be increased almost arbitrarily (Not in diameter, but in length.) and he can get into the wings to be built in.
Das
Ganze funktioniert folgendermaßen:
An
der Unterseite der Tragflächen,
nahe der Vorderkante ist entlang der Tragfläche eine rechteckige Öffnung,
durch die die Luft vom Gebläse
angesaugt wird. (Ähnlich
wie ein Haifischmaul, daher Sharkwing – Haifischflügel). Das
Gebläse
beschleunigt die Luft auf annähernd
Umfangsgeschwindigkeit des Gebläseflügels und
an der Hinterkante der Tragfläche
wird sie ausgeblasen. Da dies über
fast die gesamte Länge
der Tragfläche
geschieht, verteilt sich der Schub auch entsprechend.The whole thing works like this:
At the bottom of the wings, near the leading edge, there is a rectangular opening along the wing, through which the air is sucked in by the fan. (Similar to a shark's mouth, hence sharkwing - shark wings). The fan accelerates the air to approximately peripheral speed of the fan blade and at the trailing edge of the airfoil it is blown out. Since this happens over almost the entire length of the wing, the thrust is also distributed accordingly.
Die Ausblasöffnung kann durch zwei bewegliche Klappen vergrößert und verkleinert werden. Eine Vergrößerung der Ausblasöffnung auf das Doppelte reduziert die Geschwindigkeit der ausgeblasenen Luft auf die Hälfte, dabei verdoppelt sich gleichzeitig der Schub, sehr hilfreich beim Start. Wird die Öffnung auf die Hälfte des Luftkanalquerschnitts verringert, verdoppelt sich die Geschwindigkeit der Luft, gleichzeitig halbiert sich der Schub, damit kann bei entsprechender Antriebsleistung sogar Überschallgeschwindigkeit erreicht werden. Der variable Ausblastrichter wirkt wie ein automatisches Getriebe beim Auto, er passt den Schub der Geschwindigkeit an, entsprechend dem Drehmoment beim Auto.The exhaust vent can be enlarged and reduced by two movable flaps. A Magnification of the exhaust vent doubled the speed of the blown out Air in half, at the same time doubling the thrust, very helpful in the Begin. Will the opening in half reduces the air channel cross-section, the speed doubles the air, at the same time halves the thrust, so can with appropriate Drive power even supersonic speed be achieved. The variable discharge funnel acts like an automatic one Transmission at the car, it adjusts the thrust of the speed, accordingly the torque in the car.
Um Turbulenzen am Rumpf zu vermeiden, sollten die Tragflächen weit hinten am Rumpf befestigt sein. Ein Canard vorne sorgt für bessere Flugeigenschaften.Around To avoid turbulence on the fuselage, the wings should be wide be attached to the rear of the hull. A Canard front makes for better Flight characteristics.
Die beiden Motoren, welche die Gebläse in den Tragflächen antreiben, werden im Rumpf montiert, sind somit auch während des Fluges zugänglich. Die Gebläse müssen unterteilt und mehrfach gelagert sein, um den vertikalen Schwingungen der Tragflächen folgen zu können.The both motors, which are the blowers in the wings drive, are mounted in the fuselage, are thus also during the Flight accessible. The fans have to divided and stored several times to the vertical vibrations the wings to be able to follow.
