Abstract

Wind-tunnel balance, with which the forces acting in a flow on an object, especially a vehicle, are measured and the moments acting on the vehicle are calculated by means of a processor, a device being provided for applying defined forces from zero to full load to the object in the horizontal direction and for determining the displacement of the centre of gravity of the object resulting from the respective force. The force/distance function thus determined is taken into account in the determination of the moments, the respective force acting on the object being determined by means of the force measuring devices of the wind-tunnel balance itself.

Description

Die Erfindung betrifft eine Windkanalwaage gemäß Patent (Patentanmeldung P 37 15 460.5).The invention relates to a wind tunnel balance according to the patent (Patent application P 37 15 460.5).

Gemäß den Ausführungsbeispielen nach Fig. 1 und 2 des Hauptpatents läßt sich die jeweils am Fahrzeug wirkende Kraft mittels einer Kraftmeßvorrichtung feststellen.According to the embodiments of FIGS. 1 and 2 of the main patent, the force acting on the vehicle can be determined by means of a force measuring device.

Die vorliegende Erfindung stellt sich die Aufgabe diese Windkanalwaage weiter zu vereinfachen.The present invention has as its object To further simplify the wind tunnel scale.

Gemäß der Erfindung gelingt dies dadurch, daß die jeweils am Fahrzeug angreifende Kraft mittels der Windkanalwaage selbst festgestellt wird.According to the invention, this is achieved in that the Force applied to the vehicle by means of the wind tunnel scale itself is detected.
