Description
Kugelförmiger Rumpf für Hubschrauber
Daher soll für Hubschrauber mit kugelförmigem Rumpf nach der Erfindung ein die Kugel zu einer windschnittigen Form ergänzender aufblas- und raffbarer kegeliger Sack dienen. Durch diese Einrichtung wird die Bildung von Verwirbelungen beim Ablauf der Strömungen am Rumpf vermieden, der Luftwiderstand herabgesetzt und der Vorschub somit wesentlich erhöht.Therefore, for helicopters with a spherical fuselage according to the invention an inflatable and gatherable conical shape that complements the ball to create a streamlined shape Serve sack. This facility prevents turbulence during the drainage process the currents on the fuselage are avoided, the air resistance is reduced and the advance is reduced thus significantly increased.
In der Zeichnung sind Ausführungsformen des Hubschraubers mit kugeligem Rumpf dargestellt.In the drawing are embodiments of the helicopter with spherical Hull shown.
Abb. i zeigt den Hubschrauber nach Verlassen des Erdbodens mit noch gerafftem Luftsack i. Letzterer ist etwas unterhalb der Rumpfmitte 2 unmittelbar an der Außenhülle befestigt.Fig. I shows the helicopter after leaving the ground with still gathered airbag i. The latter is just below the middle of the fuselage 2 attached to the outer shell.
Abb. 2 zeigt den Luftsack bereits vollständig ausgelassen. Der Hubschrauber befindet sich im vollen Steigflug.Fig. 2 shows the airbag already completely omitted. The helicopter is in full climb.
Abb.3. Der Luftsack wird wieder eingezogen bzw. gerafft, das Flugzeug ist im Sinkflug begriffen. Die gezeichneten kleinen Pfeile geben die jeweilige Flugrichtung an.Fig 3. The airbag is retracted or gathered again, the aircraft is about to descend. The small arrows drawn indicate the direction of flight at.
Soll auch im Streckenflug ein höherer Vorschub erreicht werden, so wird ein den Sack einfassender Ring q., 5 an der Kugel in ein oder zwei Ebenen (kardanartig) schwenkbar gelagert.If a higher advance is to be achieved in cross-country flights, so a ring encircling the sack q., 5 is placed on the ball in one or two planes (cardan-like) pivoted.
Abb. q. zeigt einen in einer Ebene schwenkbaren Ring mit Luftsack. Abb. 5 stellt einen Hubschrauber mit kardanartig in zwei Ebenen schwenkbarem Sack mit einfassendem Ring dar. Die Rumpfform pafft sich der durch dünne Linien markierten Strömung glatt an. Abreißen der Strömung und Verwirbelungen können auch hier im Streckenflug hinter dem Rumpf nicht eintreten. Für Fall IV und V kann der obere starre Teil 6 des Luftsackes aus durchsichtigem Werkstoff hergestellt sein.Fig.q. shows a ring with an air bag that can be pivoted in one plane. Fig. 5 shows a helicopter with a gimbal-like sack that can be swiveled in two planes with a surrounding ring. The shape of the fuselage is like that marked by thin lines Flow smoothly. Tearing off the flow and turbulence can also occur here in the Do not enter cross-country flight behind the fuselage. For cases IV and V, the upper rigid part 6 of the airbag made of transparent material.
Das Auslassen des Luftsackes erfolgt durch Lösen des aufgerollten Teils und Einblasen von Preßluft, Abgasen mit Luft vermischt oder anderen Mitteln. Der Luftsack wird durch das Füllgas straff gehalten, das Raffen geschieht vermittels Kabel und Winde. Die Luft entweicht zuletzt aus der Sackhülle durch eine Anzahl Öffnungen 7.The airbag is released by loosening the rolled up one Partly and blowing in compressed air, exhaust gases mixed with air or other means. The airbag is held taut by the filling gas, the shirring is done by means of Cable and winch. The air finally escapes from the bag envelope through a number Openings 7.
