Abstract

Bei üblichen Messeinrichtungen verfälschen so genannte "Endeffekte" die Messergebnisse. Beispielsweise führt eine Beschleunigung des Prüfkörpers zu Strömungen, welche den zu messenden Strömungen während einer stationären Bewegung überlagert werden. DOLLAR A Erfindungsgemäß ist zwischen einem Beschleunigungsbereich (12, 14) und einem Messbereich (13) ein Trennkörper angeordnet, welcher über eine Klappe oder Schlitze verfügt, durch die der Prüfkörper (11) hindurchtreten kann. Vor und nach dem Hindurchtritt des Prüfkörpers vermeidet der Trennkörper (18, 19) eine Kopplung von Strömungen in dem Beschleunigungsbereich (12, 14) und in dem Messbereich (13). DOLLAR A Messung des Strömungsverhaltens in Wasserschleppkanälen oder Katapultanlagen, insbesondere zur Untersuchung von Wirbelschleppen von Prüfkörpern wie Luftfahrzeuge, Landfahrzeuge wie ein Kraftfahrzeug oder eine Eisenbahn oder Wasserfahrzeuge.In conventional measuring devices, so-called "end effects" distort the measurement results. For example, an acceleration of the test body leads to flows which are superimposed on the flows to be measured during a stationary movement. DOLLAR A According to the invention, a separating body is arranged between an acceleration region (12, 14) and a measuring region (13), which has a flap or slots through which the test body (11) can pass. Before and after the passage of the test specimen, the separating body (18, 19) avoids a coupling of flows in the acceleration region (12, 14) and in the measuring region (13). DOLLAR A measurement of the flow behavior in water trailing channels or catapult systems, in particular for the investigation of wake turbulence of test specimens such as aircraft, land vehicles such as a motor vehicle or a railway or watercraft.
