UNIVERSAL ELASTIC-LIKE AERODYNAMIC MODEL AND METHOD OF MAKING SAID MODEL Russian patent published in 2012 - IPC G01M9/08 

FIELD: physics.

SUBSTANCE: model has a force core piece and one detachable cover. The core piece is in form of part of a profile which includes the entire top surface, e.g., a wing, as well as the bottom surface of the nose of the wing. At points where the cover of the bottom part of the wing profile is located in the material of the force core piece, having not less than 70-85% total wing stiffness, there is a depression which forms between the core piece and the cover, an inner free space with volume of not less than 5-10% of the entire inner volume bounded by the exterior outline of the model, in which there are inverted L shaped drainage pipes, sensors for measuring distribution of pressure on the surface of the model, as well as a drive and additional weights needed to achieve mass-inertial similarity of the model. The method of making said model is characterised by wide use of numerically controlled machine tools for rapid high-precision and cheap manufacturing of the core piece and the cover. High accuracy of simulation is provided owing to use of iterative perfection of the stiffness of the core piece by measuring the contribution of wing stiffness into total stiffness of the model and correcting the mathematical model of the core piece.

EFFECT: simple design, high rapidness of the process of making high-quality elastic-like aerodynamic models.
