Aufgabe der Düse ist es, die am Austritt der Turbine vorhandene potentielle Energie in kinetische Energie umzuwandeln. Sie dient im wesentlichen der Aufrechterhaltung des Druck- und Leistungsniveaus im gesamten Triebwerk und damit nur indirekt der Schuberzeugung (der Schub eines Triebwerks wird nicht in der Düse erzeugt - sie bewirkt vielmehr einen nicht unerheblichen Widerstand!). Je nach Bauart unterscheidet man:
nicht erweiterte Düse ⟹ rein konvergent
erweiterte Düse ⟹ konvergent-divergent
Die Schubumkehr besteht entweder aus Spoilerklappen, die, unmittelbar in den Abgasstrahl hineingeschwenkt, die Strömung umlenken (Innenkreis), oder es wird ein Umlenkgitter, das mit Hilfe beweglicher Klappen während des Reiseflugs abgedeckt ist, verwendet (Außenkreis).Beim Betätigen der Schubumkehr wird das Umlenkgitter freigegeben, wobei der Strömungskanal durch Schwenken des inneren Abdeckblechs gleichzeitig verschlossen wird. Beide Schubumkehrvorrichtungen sind an der Gondel des Rolls-Royce-Triebwerks RB 211 verwirklicht (siehe Bild 3.26).

Task of the nozzle is to convert the potential energy existing at the outlet of the turbine into kinetic energy. It serves essentially to maintain the pressure and performance levels in the entire engine and thus only indirectly generating thrust (the thrust of an engine is not created in the nozzle - it causes a considerable resistance instead!). Distinction is made depending on the type: not advanced nozzle ⟹ in convergent Advanced nozzle convergent divergent ⟹The thrust reversers consists either of spoiler flaps, who swung in directly into the exhaust stream, divert the flow (inner circle), or it is used a Umlenkgitter, which is covered with the help of portable folding in-flight travel (outer circle). When activating the thrust reversers, the deflection grille is released with the lazy river at the same time is closed by turning the inner cover plate. Both thrust reversing devices are realized on the nacelle of the Rolls Royce engine RB 211 (fig. 3.26).

The object of the nozzle is to convert existing potential energy into kinetic energy at the exit of the turbine. You essentially serves to maintain the pressure and levels of performance throughout the engine and thus only indirectly the thrust generation (the thrust of an engine is not generated in the die - rather, it causes a significant resistance!). Depending on the type divided into:
non-expanded nozzle ⟹ purely convergent
extended nozzle ⟹ convergent-divergent
The thrust reverser consists either of spoiler flaps, immediately swung into the exhaust stream, the flow deflecting (inner circle), or there is a deflector, the movable means flap is covered during cruise, used (outer circle) .When operating the thrust reverser the deflector is released, wherein the flow channel is closed at the same time by turning the inner shroud. Both thrust reversers are realized on the nacelle of the Rolls-Royce RB 211 engine (see Figure 3.26).

It is task of the nozzle at the outlet of the turbine, the existing potential energy into kinetic energy. It is mainly used for the maintenance of the pressure and performance throughout the engine and thus only indirectly Schuberzeugung (the thrust of the engine is not generated in the nozzle - rather a not inconsiderable resistance! ).Depending on the design distinguishes:
advanced nozzle ⟹ purely convergent
advanced nozzle ⟹ convergent-divergent
Spoilerklappen consists either of the thrust reverser, the directly into the exhaust gas stream hineingeschwenkt, divert the flow (inner circle), or it is a Umlenkgitter, the using moving flaps during cruise is covered, used (outer circle).When the thrust reverser is released with the Umlenkgitter meanders through the swiveling of the inner bracket is closed simultaneously. Both thrust reversers are at the gondola of the Rolls-Royce RB 211 engine achieved (see Figure 3.26 ).
