The development of new measuring techniques requires new data formats and data structures. Due to the rigidity of old formats and structures adaptation to new requirements are impossible.
Users of wind tunnels rely for the interpretation of test results on data provided by the wind tunnel operator.
Verification of the transition triggering was done using acenaphthene visualization. A sample result, obtained with a heightof102 µm , is shown in figure 3.
This paper presents a review of the testing techniques currently used to study the engine integration in the different ONERA wind tunnels, covering the whole speed range of current and future aircr
A new data acquisition system with digital filtering (SAFIN) was installed at the Modane S2MA wind tunnel, in January 2007.
Wake measurement tests were carried out in the S2MA wind tunnel during December 2005 and January 2006, as part of the "Falcon Propulsive System Drag" study, under the leadership of the ONERA-DAAP d
Since the beginning of its large wind tunnel operations, ONERA has continuously improved its measurement devices, in particular the strain-gauge balances.
