Description
Vorrichtung, um auf Gleitfliegern die Änderungen der Windströmungen durch einen sich mit diesen ändernden Ton wahrnehmbar zu machen. Um bei motorlosen Flugzeugen die Energie des Windes restlos ausbeuten zu können, und um die Böen und die Veränderlichkeit der Windströmungen erkennbar zu machen, ist bereits vorgeschlagen, die Änderungen der Windströmungen durch einen sich mit diesen ändernden Ton wahrnehmbar zu machen. Dem Windstrom wird eine Sirene ausgesetzt, die bei Änderung der Windströmungen ihre Umlaufsgeschwindigkeit und damit ihren Ton ändert.Device to monitor changes in wind currents on gliders by making a tone that changes with them perceptible. To with motorless Aircraft to be able to fully exploit the energy of the wind, and the gusts and to make the variability of the wind currents recognizable has already been proposed, the changes in the wind currents are perceptible through a tone that changes with them close. A siren is exposed to the wind current, which sounds when the wind currents change their speed of rotation and thus their tone changes.
Gemäß vorliegender Erfindung erfolgt die Wahrnehmung auf elektrisch-akustischem Wege. Hierfür geeignete Elemente sind empfindlicher als Sirenen. Die Vorrichtung kann beispielsweise aus einem Mikrophon bestehen, an dessen Membran ein kleines Stäbchen befestigt ist, welches durch die Luft, je nach deren Bewegungsstärke und Bewegungsrichtung mehr oder weniger verbogen, erschüttert oder in Schwingung versetzt wird. Diese Vorgänge erzeugen in dem Mikrophon, an welchem das Stäbchen befestigt ist, Änderungen, welche sich in einem damit verbundenen, vom Flieger getragenen Telephon als Töne bemerkbar machen. Aus der Art des erzeugten Tones kann der Flieger Rückschlüsse auf die Strömungsverhältnisse machen.According to the present invention, the perception takes place on an electric-acoustic basis Ways. Elements suitable for this are more sensitive than sirens. The device can for example consist of a microphone with a small one on its membrane Chopsticks attached, which through the air, depending on their strength of movement and Direction of movement more or less bent, jolted or set in vibration will. These processes produce in the microphone to which the rod is attached is, changes that result in an associated, carried by the air Make the telephone perceptible as tones. The aviator can use the type of sound produced Make conclusions about the flow conditions.
Zweckmäßig werden zwei Mikrophone nebeneinander angeordnet, deren Empfangsflächen senkrecht zueinander stehen, so daß sie nicht nur auf jede Windrichtung ansprechen, sondern gerade diese selbst feststellen lassen. Die durch die beiden Mikrophone bzw. anderen Aufnahmeapparate erzeugten Töne oder Geräusche können einzeln auf die Hörapparate übertragen oder zu einem gemeinsamen Ton oder Geräusch zusammengefaßt werden. In letzterem Falle enstehen, wenn die Schwingungszahlen nur wenig verschieden sind, die bekannten akustischen Schwebungen, bei größeren Unterschieden in den Schwingungszahlen Kombinationstöne. Durch diese Anordnung ist der Flieger imstande, schon geringere Änderungen im Verhältnis der aus verschiedenen Richtungen kommenden Windstärken und damit auch Änderungen der Windrichtungen wahrzunehmen.Appropriately, two microphones are arranged side by side, their Receiving surfaces are perpendicular to each other so that they do not only face any wind direction address, but let them determine for yourself. The one by the two Tones or noises generated by microphones or other recording devices can be used individually transmitted to the hearing aids or combined into a common tone or noise will. In the latter case arise when the oscillation numbers are only slightly different are the well-known acoustic beats, with larger differences in the number of vibrations Combination tones. With this arrangement, the aviator is able to achieve even lower Changes in the ratio of wind strengths coming from different directions and thus also to perceive changes in the wind directions.
Ein weiterer geeigneter Fühler für den Gleitflieger bildet das Anemometer, an welchem man einen Schleifkontakt anbringt. Auf diesem oder auf dem Anemometer selbst schleift eine Kontaktfeder und erzeugt dadurch gegebenenfalls unter Zwischenschaltung von Stromquelle und Telephon einen Ton, welcher auf den Hörapparat oder die sonstige Vorrichtung zur Wahrnehmbarmachung übertragen wird. Vorteilhaft können auch hier wieder zwei unter einem Winkel angeordnete Fühler Verwendung finden, welche jede Windbewegung, aus welcher Richtung der Rose sie .auch kommt, wahrnehmbar zu machen vermögen.Another suitable sensor for the glider is the anemometer, to which a sliding contact is attached. On this one or on the anemometer itself grinds a contact spring and thus generates it with interconnection, if necessary from the power source and telephone a tone which is heard on the hearing aid or the other Device for making perceptible is transmitted. Can also be advantageous here again two sensors arranged at an angle are used, which each Wind movement, from which direction the rose it is coming, to make perceptible capital.
Ferner können Muscheln oder ähnliche Hohlräume mit geeigneten Schallöchern Verwendung finden, in denen durch die Luftströmung ein Sausen entsteht, das elektrisch und gegebenenfalls verstärkt dem Ohr des Fliegers zugeführt wird.Furthermore, shells or similar cavities with suitable sound holes can be used, in which the air flow creates an electrical whirring sound and, if necessary, is fed to the aviator's ear more intensively.
