Description
Die Leistung eines Hubschraubers hängt im wesentlichen von der in der Zeiteinheit erfaßten Luftmenge ab, weshalb man auch auf die großen Durchmesser der Flügel gekommen ist. Zwar kann man den Durchmesser verkleinern und die Flügel in einem sie umschließenden Gehäuse laufen lassen, erkauft dies jedoch mit einer geringeren Wirkung d. h. mit einem unwirtschaftlichen Arbeiten. Dieses wird noch dadurch erhöht, daß der nach unten ausblasende Luftstrom auf Kabinenteile oder Motorverkleidungen trifft.The performance of a helicopter essentially depends on the in the amount of air recorded from the unit of time, which is why the large diameter is also used the wing has come. You can reduce the diameter and the wings run in a housing that encloses them, but this is paid for with a less impact d. H. with an uneconomical work. This is still going to increased by the fact that the downward blown air flow on cabin parts or engine panels meets.
Erfindungsgemäß wird der Wirkungsgrad der Hubschraube dadurch verbessert, daß ihr durch ein zusätzlich angeordnetes Radialgebläse Luft zugedrückt wird, also gewissermaßen eine »Aufladung« stattfindet.According to the invention, the efficiency of the lifting screw is improved by that air is blocked by an additionally arranged radial fan, that is to a certain extent a "charging" takes place.
Dadurch, daß das Aufladegebläse die Luft über der Kabine wegsaugt und sie den Auftrieberzeugenden, Propellern zuführt, welche ihrerseits nun die Luft seitlich aller sonstigen Konstruktionsteile frei nach unten ausbläst, wird der Wirkungsgrad insgesamt erhöht: die erfaßte Luftmenge ist groß; über der Kabine ist Unterdruck statt bisher Überdruck; der ausblasende Strahl geht unbehindert frei nach unten.Because the supercharger sucks the air away from above the cabin and feeds them to the propellers that generate buoyancy, which in turn feed the air the side of all other construction parts freely blows down, the efficiency increased overall: the amount of air detected is large; there is negative pressure above the cabin instead of previously overpressure; the jet that blows out goes freely downwards.
Zu diesem Zweck wird die Kabine als runde Zelle ausgebildet, über der das Radialgebläse die Luft wegsaugt und sie dem die Zelle seitlich überragenden Axialpropeller zudrückt, der sie nach unten beschleunigt. Der Motor kann unterhalb der Zelle angeordnet werden, und die Antriebswelle durchsetzt die Kabine zentrisch.For this purpose, the cabin is designed as a round cell, over which the radial fan sucks the air away and it protrudes laterally over the cell Axial propeller pushes shut, which accelerates it downwards. The engine can be underneath the cell are arranged, and the drive shaft centrally penetrates the cabin.
Radial- und Axialgebläse können in bekannter Weise gegenläufig ausgebildet werden, sie können aber auch fest miteinander verbunden gleichsinnig laufen, wobei beide Gebläseschaufeltypen eine ineinanderfließende Übergangsform zeigen.Radial and axial fans can be designed to run in opposite directions in a known manner but they can also run in the same direction, firmly connected to one another, whereby both types of fan blades show a merging transition shape.
Derartig kombinierte Gebläse können sowohl über, wie unter der Kabine angeordnet werden. Entsprechend angeordnete, auch steuerbare Leitschaufeln heben das Gegendrehmoment in bekannter Weise auf. Der ausblasende Luftstrom kann auch vorn, durch diese Leitschaufeln gescheitelt, beiderseits der Kabine nach hinten umgelenkt werden, so in bekannter Weise Vortrieb erzeugend. Die Zeichnung zeigt. ein Ausführungsbeispiel in Seitenansicht (rechts) und halbseitigem Schnitt (links). Über dem durch die Federbeine I abgestützten Motorraum 2 ist die Kabine 3 mit ihrer Verglasung 5 und der Einsteigtür 4 angeordnet.Such combined fans can be both above and below the cabin to be ordered. Lift appropriately arranged, also controllable guide vanes the counter torque in a known manner. The blowing air flow can also in front, parted by these guide vanes, on both sides of the cabin to the rear are deflected, so generating propulsion in a known manner. The drawing shows. an embodiment in side view (right) and half-sided section (left). Above the engine compartment 2 supported by the struts I is the cabin 3 with its Glazing 5 and the entrance door 4 arranged.
Die durch die Verkleidung 7 geschützte Welle 6 geht zentrisch durch die Kabine und treibt das Gebläserad 8/9 an, das sich aus dem radial blasenden Teil 9 und dem axial blasenden Teil 8 zusammensetzt. Letzterer Teil saugt unmittelbar von oben Luft an und bekommt zusätzlich Luft durch das Radialgebläse 9 zugedrückt, unter dementsprechender Ausbildung der Schaufeln, insbesondere in den Übergang von den Schaufeln 9 zu den Schaufeln B. Das Gebläse ist durch den Mantel Io geschützt. Unterhalb sind die durch einen Steuerungring I2 einstellbaren Leitschaufeln II angeordnet.The shaft 6 protected by the cladding 7 goes through centrally the cabin and drives the fan wheel 8/9, which emerges from the radial blowing part 9 and the axially blowing part 8 composed. The latter part sucks immediately air is drawn in from above and air is additionally compressed by the radial fan 9, with a corresponding design of the blades, especially in the transition from the blades 9 to the blades B. The fan is protected by the jacket Io. The guide vanes II, which can be adjusted by means of a control ring I2, are arranged below.
