Abstract
Due to the high costs, time and work consuming of a model manufacturing, it is often impossible to conduct wind tunnel tests at the early stages of an aircraft design, especially, when the geometry of the plane is still subject to change. The modern rapid manufacturing methods can overcome this problem. In 2017 in the Institute of Aviation, Warsaw, Poland the works on the conceptual design of a new type of an aircraft has been started. A few configurations of the plane were designed and analysed by the means of computational fluid dynamics (CFD). For the chosen configuration a model have been built and tested in a 1.5 m diameter wind tunnel. The fuselage of the model and its vertical and horizontal stabilizers were 3D printed. This study discuses advantages and shortcomings of employing rapid manufacturing methods for creating test models. Special consideration was put to the cost and time saving, model design aspects, model quality and possibility to introduce changes to the model configuration.
