Embodiment Construction

[0054] From figure 1 As can be seen in the measurement system 1 according to the invention, an object 2 is placed in a controlled volume 3 provided in a flow channel or a wind tunnel. Object 2 may be any desired object, in particular a three-dimensional model. A three-dimensional model is, for example, a model of an aircraft or an aircraft component. Object 2 can also be any other object to be studied, for example, a vehicle or a building to be studied. The object 2 to be investigated is in the controlled volume, ie the volume or size of the object 2 is smaller than the controlled volume 3 . The controlled volume 3 within the flow channel is a closed volume and has a plurality of defined surfaces. The geometry of the controlled volume 3 can be chosen according to the geometry of the object 2 to be investigated. Preferably, the coordinates of the defined surface of the controlled volume are stored in a memory to control the measuring device. exist figure 1 In the shown em...

Abstract

The present invention provides a method and a system for determining forces which act on a body with a controlled volume which is provided inside the flow tunnel and in which the body is arranged. A first measuring means is used to measure a pressure distribution for each surface defining the controlled volume. A second measuring means measures a velocity field for each defining surface of the controlled volume. Furthermore, a calculation unit is provided for calculating the forces acting on the body as a function of the pressure distributions and velocity fields measured for the defining surfaces of the controlled volume.

Description

Background technique [0001] In order to study the aerodynamic and aeroacoustic properties of an object, a true scale three-dimensional model of the object or object to be studied is placed in a wind tunnel or flow tunnel. For example, a model of an airplane or other vehicle is arranged in a flow channel to be exposed to fluid flow, such as air flow. In addition to studying models of vehicles, runners can also be used to study buildings. In this regard, a three-dimensional model of a building, such as a multi-storey building or a bridge, is arranged in a wind tunnel and exposed to air currents. [0002] Due to the limited diameter of the runners, objects are rarely studied in the runners at their actual size. For this reason, realistic scale three-dimensional models are usually made of large objects and arranged in flow channels to study the flow behavior of the objects. [0003] For objects, especially aircraft, it is important when studying the aerodynamic behavior of the ...
