    摘要: An aerodynamic pressure sensing system for an such as an airplane lifting surface, rotor blade etc. is disclosed wherein a plurality of pressure probes (7) are arranged on the upper and lower surfaces of the airfoil-shaped body (1) to sense aerodynamic pressure at discrete locations thereof, wherein the pressure sensitive elements (7) are arranged to form a plurality of rows (8) on said upper and lower surfaces. According to the invention between 55-75% of the total number of the pressure sensitive elements (7) are arranged at the leading edge section, and the remaining pressure sensitive elements are arranged at the intermediate section of the airfoil-shaped body. The invention allows measuring aerodynamic forces generated at the leading edge of the airfoil and particularly the suction peak more precisely and with a reduced number of pressure probes.

    摘要: A method and apparatus for generating a flow of heated air (124) in an airfoil model of an inlet (104) of an aircraft (108) engine. Heated air (124) is sent into a duct system associated with the airfoil model (110) of the inlet (104) of the aircraft (108) engine. The heated air (124) is circulated within the airfoil model (110) of the inlet (104) of the aircraft (108) engine using the duct system in a manner that simulates air flowing in the inlet (104) of the aircraft (108) engine.

    摘要: Diese Vorrichtung dient zur Überprüfung von Luftgeräuschen eines Kraftfahrzeugs, insbesondere eines Personenkraftwagens, welche Luftgeräusche durch Anströmen von Luft auf eine Außenhaut eines Aufbaus des Personenkraftwagens entstehen.
    Um diese Vorrichtung zu optimieren, werden an dem unbewegten Personenkraftwagen in Bereichen, wo Dichtungen zwischen feststehenden Aufbaustrukturen und beweglichen Aufbauelementen des Aufbaus verlaufen, gezielte Luftströmungen mittels eines Gebläses aufgebracht, und die durch die Luftströmungen auftretenden Luftgeräusche werden subjektiv und/oder objektiv gemessen.
    Dabei ist ein einen Ausströmquerschnitt umfassende Gebläse Bestandteil der Vorrichtung, die mit einer Blasdüse zur Beaufschlagung von Messpunkten an der Außenhaut versehen ist.
