![]() Preview of Autodesk Ecotect Analysis 2010 Autodesk's Membrano provides a preview of the features and functionality of, a comprehensive, concept-to-detail sustainable design analysis tool that provides a wide range of simulation and analysis functionality. In that way a stationary observer could study the flying object in action, and could measure the aerodynamic forces being imposed on it. The wind tunnel was envisioned as a means of reversing the usual paradigm: instead of the air standing still and an object moving at speed through it, the same effect would be obtained if the object stood still and the air moved at speed past it. The earliest wind tunnels were invented towards the end of the 19th century, in the early days of aeronautic research, when many attempted to develop successful heavier-than-air flying machines. ![]() ![]() The test object, often called a wind tunnel model is instrumented with suitable sensors to measure aerodynamic forces, pressure distribution, or other aerodynamic-related characteristics. Air is made to move past the object by a powerful fan system or other means.
