Polish Air Force Academy: Researcher Studies Aerodynamics of 3D Printed Aircraft Model https://ift.tt/2GL89Go Robert Babel of the Polish Air Force Academy recently published ‘The initial analysis of the aerodynamic characteristics of a 3D printed model of an aircraft’ as he explored use of the progressive technology in aerodynamics studies, and designs. The emphasis was on studying stream-lined design and stability to create a plane model that could withstand turbulence and any other forces that might place stress on it. While remote control was available, Babel’s goal was to 3D print a plane model that could handle wind gusts and then balance itself automatically, without the use of electronics.
Stability in terms of the y-axis is referred to as longitudinal, providing tail. In relation to both the x- and z-axis, stability is lateral and directional. Using the proper characteristics to understand aircraft performance is vital, although it varies about different conditions for the aircraft whether it is taking off, landing, climbing, or moving forward at maximum speed.
To continue his study in aerodynamic characteristics, Babel used FDM 3D printing to fabricate hull components, performing all testing in a closed-circuit aerodynamic tunnel with an open-circuit circular measuring space. The 3D printed model did not work very well on the first test run, it should be noted, as some of the 3D printing parameters were off, and had to be adjusted. This is a perfect example though of one of the greatest benefits of 3D printing. When an error is discovered, adjustments can be made quickly whether in design or technical settings, and a new print can be manufactured quickly and affordably—and without having to wait on a middleman. The model’s torque, along the transverse axis was responsible for tilting it, and Babel suggests keeping momentum low for proper flight measures. The scientist also points out that the results of this study only ‘constitute a small part of the research’ that should be performed regarding creation of this type of hull.
Aside from the vast field of medicine, it is hard to think of another industry that has been more impacted by 3D printing than aerospace, with NASA enjoying the benefits of 3D printing for decades—although today continually impressing us with rocket components, concepts for new Mars rovers, and even colonization in space. On the smaller level, we have also followed numerous stories regarding projects where scientists, designers, engineers, and students have been involved in using 3D printing to create innovative components.
