Abstract

An improved effect aircraft propeller has a swashplate mounting with a two part construction; one fixed part (1) and one movable part, linked by a bearing. A control linkage (3) varies the blade pitch cyclically, as for a helicopter rotor, to vary the airflow onto the control and support planes to generate lift and steering control even at low speeds.

Description

Die Erfindung betrifft ein Fluggerät mit zumindest einem Propeller, dessen zumindest eines Rotorblatt in einer etwa vertikalen Ebene dreht.The The invention relates to an aircraft with at least one propeller, whose at least one rotor blade turns in an approximately vertical plane.

Ein bekannter Propeller weist meist mehrere Rotorblätter auf, welche in einem Winkel angestellt sind und dadurch in der Rotation einen Schub erzeugen. Dieser Winkel ist in manchen Fällen, im Betrieb, kollektiv verstellbar. Dadurch kann der Schub variiert, bzw. umgekehrt werden.One known propeller usually has a plurality of rotor blades, which at an angle are employed and thereby generate a thrust in the rotation. This angle is in some cases in operation, collectively adjustable. This can vary the thrust, or be reversed.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, den Propeller zur Steuerung der Flugrichtung des Flugzeugs zu nutzen.Of the present invention is based on the object, the propeller to use for controlling the direction of flight of the aircraft.

Zur Lösung dieser Aufgabe führt, dass das Rotorblatt zyklisch verstellbar ist.to solution performs this task, that the rotor blade is cyclically adjustable.

Durch eine zyklische Rotorverstellung in eine oder mehrere Richtungen wird die Flugrichtung des Flugzeugs beeinflusst.By a cyclic rotor adjustment in one or more directions the direction of flight of the aircraft is influenced.

Mit dieser Erfindung wird erreicht, dass ein Flugzeug auch bei minimaler Anströmung der Ruderflächen steuerbar bleibt. Insbesondere beim Kunstflug ermöglicht diese Neuerung völlig neue Flugfiguren.With of this invention is achieved that an aircraft even at minimal inflow the rudder areas remains controllable. Especially during aerobatics this allows Innovation completely new flying figures.

Eine vorteilhafte Ausgestaltung der Erfindung ist im Schutzanspruch 2 angegeben. Die Weiterbildung nach Schutzanspruch 2 führt zu einer Kombination aus kollektiver und zyklischer Propellerverstellung.A advantageous embodiment of the invention is in the protection claim 2 specified. The training for protection claim 2 leads to a combination from collective and cyclical propeller adjustment.

Ein Ausführungsbeispiel der Erfindung wird anhand der Zeichnungen 1 und 2 erläutert. Zwischen Motor und Rotor ist auf der Motorwelle eine Taumelscheibe, ähnlich wie bei Hubschraubern üblich, angebracht. Diese Taumelscheibe, die aus einem mitdrehendem 2 und einem nicht mitdrehendem 1 Teil, welche durch ein Kugellager miteinander verbunden sind, besteht, überträgt die zyklische Blattverstellung auf den Rotor. Wird der Steuerhebel 3 ausgelenkt, erzeugen die Rotorblätter eine asymmetrischen Schub 4 und damit eine Steuerkraft.An embodiment of the invention will be with reference to the drawings 1 and 2 explained. Between the engine and rotor, a swash plate, similar to helicopters, is mounted on the motor shaft. This swash plate, which consists of a co-rotating 2 and a non-rotating part 1, which are connected by a ball bearing, transmits the cyclic pitch on the rotor. Will the control lever 3 deflected, the rotor blades produce an asymmetric thrust 4 and thus a control force.
