Description

Schwenkbare Strahl-Triebwerksgondel für VTOL- oder STOL-Flugzeuge Bei Flugzeugen sind oft mehrere Strahltriebwerke in einer Gondel zusammengefaßt. Im Reiseflug ist der Leistungsbedarf bedeutend geringer als bei Start und Landung, insbesondere bei VTOL- und STOL-Flugzeugen mit schwenkbaren Triebwerksgondeln. Eine Drosselung aller Triebwerke würde einen zu hohen Kraftstoffverbrauch zur Folge haben. Ein niedrigerer Kraftstoffverbrauch ergibt sich durch Stillsetzen eines oder mehrerer Triebwerke jeder Gondel.Pivoting jet engine nacelle for VTOL or STOL aircraft In aircraft, several jet engines are often combined in a nacelle. The power requirement is significantly lower during cruise than during take-off and landing, especially on VTOL and STOL aircraft with swiveling engine nacelles. One Throttling all engines would result in excessive fuel consumption. Lower fuel consumption results from shutting down one or more Engines of every nacelle.

Aufgabe der Erfindung ist es, die Luftzufuhr zu den Triebwerken so einzurichten, daß sie sowohl bei Betrieb aller Triebwerke als auch bei Stillstand eines oder mehrerer Triebwerke jeder Gondel verlustarm arbeitet. Die Erfindung besteht darin, daß der Lufteinlaufkanal zu dem Triebwerk bzw. den Triebwerken, die im Reiseflug in Betrieb sind, diesem Betriebszustand angepaßt ist, während der Lufteinlaufkanal zu den übrigen Triebwerken im Reiseflug in einer Weise, z. B. durch Klappen, verschlossen ist, daß eine glatte, widerstandsarme äußere Form der Triebwerksgondel gebildet ist.The object of the invention is to regulate the air supply to the engines to ensure that they operate both when all engines are in operation and when they are at a standstill one or more engines of each nacelle works with little loss. The invention exists that the air inlet duct to the engine or the engines that are in cruise are in operation, this operating state is adapted, while the air inlet duct to the other engines in cruise in such a way. B. closed by flaps is that a smooth, low-drag outer shape of the engine nacelle is formed is.

Erfindungsgemäß können an dem Lufteinlaufkanal für den Reiseflug regelbare Zusatzluftöffnungen für Start und Landung vorgesehen sein.According to the invention, adjustable air inlet ducts can be used for cruising flight Additional air openings for take-off and landing can be provided.

Die Zeichnung zeigt eine beispielsweise Ausführung der Erfindung.The drawing shows an exemplary embodiment of the invention.

In der Triebwerksgondel sind zwei Triebwerke A und B untergebracht. Von der Einlauflippe D des EinlaufsC führt ein EinlaufkanalE zumTriebwerkA.Two engines A and B are housed in the engine nacelle. From the inlet lip D of the inlet C, an inlet channel E leads to the engine A.

Der Einlauf für das zweite Triebwerk ist durch eine Klappe G in einer Weise verschließbar, daß die äußere Form der Triebwerksgondel widerstandsverringernd glatt ist und keine nennenswerte Durchströmung dieses Triebwerks stattfindet.The inlet for the second engine is through a flap G in one Lockable way that the outer shape of the engine nacelle reduces drag is smooth and there is no significant flow through this engine.

Zur Deckung des erhöhten Luftbedarfs bei Start und Landung kann dem Triebwerk A Zusatzluft durch die regelbare Klappe F zugeführt werden.To cover the increased air requirement during take-off and landing, the Engine A additional air can be supplied through the adjustable flap F.
