Mertens, C. (author)This thesis presents a novel measurement approach for aeroelastic wind tunnel testing. The key novelty of this approach is the integrated measurement of aerodynamic and structural quantities using an optical technique. The considered approach consists of combined measurements of flow tracer particles and structural markers using a Lagrangian...doctoral thesis 2023

Mertens, C. (author), Costa Fernandez, J.L. (author), Sodja, J. (author), Sciacchitano, A. (author), van Oudheusden, B.W. (author)The aeroelastic response of a highly flexible wing to periodic gust excitation is determined experimentally. The integrated optical measurement approach that is applied provides combined measurements of the structural response of the wing and the unsteady flow field around it. The aeroelastic loads acting on the wing are derived from these...conference paper 2022

Mertens, C. (author), Wolf, C. Christian (author), Gardner, Anthony D. (author), Schrijer, F.F.J. (author), van Oudheusden, B.W. (author)Advanced data processing methods for detecting unsteady boundary layer transition in periodic aerodynamic processes by means of infrared thermography measurements are presented. The thermal radiation emitted from the heated suction surface of a pitching airfoil model in subsonic flow is measured with an infrared camera. The unsteady boundary...journal article 2020

Wild, J. (author), Brezillon, J. (author), Mertins, R. (author), Quagliarella, D. (author), Germain, E. (author), Amoignon, O. (author), Moens, F. (author)The design activity within the EUROLIFT II project is targeted towards an improvement of the take-off performance of a generic transport aircraft configuration by a re-design of the trailing edge flap. The involved partners applied different optimization strategies as well as different types of flow solvers in order to cover a wide range of...conference paper 2006

LaBerge, J.G. (author)The lift, drag and pitching moment characteristics of eleven small aspect-ratio half-wing models mounted on a reflection plate were determined in the range of Mach numbers fom 1.4 to 2.5 in the N.A.E. 10-inch supersonlc tunnel. Eight of the models were of the cropped delta type while the remainlng three had a cropped arrow plan form. Primarily,...report 1954
