Description
Anordnung von Strahltriebwerken im Rumpfende eines Flugzeuges Die Erfindung bezieht sich auf ein Flugzeug mit einem luftatmenden Strahltriebwerksaggregat im Rumpfheck, wobei zwischen den an der Umfläche des Rumpfendes angeordneten Lufteinläufen und dem Triebwerksaggregat einerseits und dem Rumpfheck andererseits ,ein Kanal mit ringförmigem Querschnitt gebildet ist, durch den unter Mithilfe einer Mantelluftschraube die Grenzschicht des Rumpfes abgesaugt wird, nach Patent 11 46 761.Arrangement of jet engines in the end of the fuselage of an aircraft The invention relates to an aircraft with an air-breathing jet engine unit in the fuselage tail, with a channel with an annular cross-section being formed between the air inlets arranged on the surface of the fuselage end and the engine unit on the one hand and the fuselage tail on the other With the help of a jacketed propeller, the boundary layer of the fuselage is sucked off, according to patent 11 46 761.
In einer vorzugsweisen Anordnung nach Patent 1 146 761 treiben die Strahltriebwerke die Mantelluftschraube durch Anblasen von an den Enden der Mantelluftschraube angeordneten Turbinenschaufeln an.In a preferred arrangement according to patent 1,146,761, the drive Jet engines hit the jacketed propeller by blowing on the ends of the jacketed propeller arranged turbine blades.
Dabei zeigt sich, daß der Druck p1 hinter den Turbinenschaufeln etwa so groß wieder Druck p. hinter der Mantelluftschraube wird. Die Leistung der TL-Triebwerke kann daher über die Gasturbine nicht ganz ausgenutzt werden, da eine Expansion bis auf den Außendruck nicht möglich ist, weil der Druck p, hinter der Mantelluftschraube größer sein muß als der Außendruck.It can be seen that the pressure p1 behind the turbine blades is approximately so great again pressure p. behind the jacketed propeller. The performance of the TL engines can therefore not be fully utilized via the gas turbine, since an expansion up to on the external pressure is not possible because the pressure p, behind the jacketed propeller must be greater than the external pressure.
Die Erfindung behebt den Nachteil des Rückstaues aus p2 auf die Turbinenschaufeln durch eine besondere Abführung für die durch die Mantelluftschraube durchgesetzte Luft.The invention eliminates the disadvantage of the backwater from p2 on the turbine blades by a special discharge for the one enforced by the jacketed propeller Air.
Die Zeichnung zeigt eine beispielsweise Ausführung des Erfindungsgegenstandes.The drawing shows an example of an embodiment of the subject matter of the invention.
Die Anordnung der Triebwerke 4 und der Mantelluftschraube 1 ergibt eine Triebwerksanlage mit zwei Kreisen, wobei die Luft, welche durch die Mantelluftschraube 1 durchgesetzt wird und den zweiten Kreis bildet, durch ein besonderes Mantelrohr 5 a nach hinten abgeführt wird. Zur Abführung des Gasstrahles der Triebwerke ist .eine möglichst kurze ringförmige Gasstrahlaustrittsdüse 7 rings um die Turbinenschaufeln 2 und über diese herausragend angeordnet. Durch diese Anordnung ist es möglich, den Rückstau aus p, auf die Turbinenschaufeln in kleinsten Grenzen zu halten und dadurch die Leistung der TL-Triebwerke über die Gasturbine in weit höherem Maße auszunutzen.The arrangement of the engines 4 and the jacketed propeller 1 results in an engine system with two circles, the air which is passed through the jacketed propeller 1 and forms the second circle, is discharged through a special jacket tube 5 a to the rear. To discharge the gas jet from the engines, an annular gas jet outlet nozzle 7 which is as short as possible is arranged around the turbine blades 2 and protruding above them. This arrangement makes it possible to keep the backflow from p on the turbine blades within the smallest limits and thereby to utilize the power of the TL engines via the gas turbine to a far greater extent.
