Summary
According to the requirements of the topic JTI-CS2-2018-CFP08-REG-03-01, the proposal ESTRO will produce experimental and numerical data in flow speed and in “cruise conditions” to validate the relevant aerodynamic performance of the Regional 90 sit turboprop A/C wing including laminar flow extension measurements and wing span load distribution. In particular, the tests in wind tunnel conditions will be performed at some Reynolds numbers, whose higher value is expected to be around 7-8 millions, and at low and medium Mach numbers. Accurate pressure distributions, infrared flow images, wing deformation, wall balance and load control and alleviation measurements are expected. The data will be the result of an experimental test campaign performed in a Laminar Wind tunnel with the main objective to evaluate the laminar flow robustness, the aerodynamic performances and load control effectiveness of a turboprop A/C wing at medium/low speeds (Mach numbers up to 0.38) and wind tunnel Reynolds number around 7-8 million. Numerical simulations aim to first assess the wind tunnel experimental results and then to extrapolate the data to flight conditions. In addition, the effects of the propeller on the wing laminar flow extension will be evaluated through 3D boundary layer computations coupled to linear stability analyses based on ray theory.
