The latest edition of the ARA Newsletter has been released and is available from the following link, where you can also choose to subscribe to future issues. This issue highlights recent developments in Optical Measurement Systems at ARA.
During recent tests in the Transonic Wind Tunnel (TWT) employing ARA’s unique Gust Rig, a novel measurement technique was developed to accurately capture the high speed deformation of the wing structure due to the rapidly varying aerodynamic loads.
This system extends the existing Model Deformation Measurement (MDM) capability provided by LaVision GmbH to incorporate the use of two Vision Research Inc. Phantom v1610 high speed cameras.
The lecture programme for the Bedford Branch of the Royal Aeronautical Society has been announced for the 2017-18 period. Lectures are held in the ARA Sports & Social Club and cost £2 for non-members or free to members.
ARA will be attending at the AIAA Aviation Forum and Exposition in Denver, Colorado and will be presenting at the 3rd AIAA CFD High Lift Prediction Workshop on Saturday 3rd June at 1000. Peter Risley-Settle will showcase CFD results using the ARA Solar meshing tool and TAU flow solver from DLR.
During the recent miniPSP test entry at ARA the images collected allowed the surface pressure contours over a portion of the ARA reference model wing to be measured. As this wing was relatively highly pressure plotted the PSP data recorded could be calibrated and the post-processing would provide surface contours of the absolute static pressure over the measurement region.
