Description

Strahldüse, insbesondere für Flugzeuge, mit am Ende angeordneten, sich paarweise diametral gegenüberliegenden schwenkbaren Klappen Die Erfindung betrifft Vorrichtungen, die den Strahl von Strahldüsen ablenken können und dadurch z. B. bei Flugzeugen einen Steilstart oder eine Steuerung im Vertikalflug ermöglichen. Es sind für diesen Zweck schwenkbare Klappen bekannt, die am Ende der Strahldüse angebracht sind und sich paarweise diametral gegenüberliegen. Nach der bisher vorgeschlagenen Bauweise bedarf es jedoch eines erheblichen Kraftaufwandes, um diese Klappen in den Gasstrahl zu schwenken. Diesen Nachteil soll die Erfindung beseitigen.Jet nozzle, especially for aircraft, with arranged at the end, in pairs, diametrically opposite pivotable flaps The invention relates Devices that can deflect the beam of jet nozzles and thereby z. B. enable a steep take-off or control in vertical flight in aircraft. There are pivotable flaps known for this purpose, which are at the end of the jet nozzle are attached and are diametrically opposed in pairs. According to the previously proposed However, the construction requires a considerable amount of force to turn these flaps into to swivel the gas jet. The invention is intended to eliminate this disadvantage.

Wie die F i g. I, 1I und III zeigen, sind die Klappen k, damit sie ohne wesentlichen Kraftaufwand geschwenkt werden können, durch außerhalb des Gasstrahls liegende Verbindungslenker q beweglich miteinander verbunden und parallel geführt; dabei wird die Schwenkachse d der Klappen so gewählt, daß das Moment des Gasstrahls auf den Vorderteil der einen Klappe gleich groß und entgegengesetzt gerichtet dem Moment auf den hinteren Teil der anderen Klappe ist. Dabei ist zu beachten, daß die Gaskräfte jeweils im vorderen Drittel der Klappen angreifen.As the F i g. I, 1I and III show the flaps k so they can be pivoted without significant effort by outside the gas jet horizontal connecting links q movably connected to one another and guided in parallel; the pivot axis d of the flaps is chosen so that the moment of the gas jet on the front part of one flap of the same size and directed opposite to that Moment is on the back of the other flap. It should be noted that the gas forces attack in the front third of the flaps.

Bei dieser Bauweise heben sich die Drehmomente gegenseitig auf, die der Gasstrahl auf die Klappen ausübt; diese können deshalb ohne wesentlichen Kraftaufwand geschwenkt werden. Darin liegt der wesentliche Fortschritt der Erfindung.In this design, the torques cancel each other out the gas jet exerts on the flaps; this can therefore be done without any significant effort be swiveled. This is the essential advance of the invention.
