The study project to design and build a series of low-speed wind tunnel experiment with open. The objective is to design and build a series of low-speed wind tunnel experiment and open to find the performance of a series of low-speed wind tunnel experiment of wind from the open lift force coefficient and resistance of an object model to study the design and construction of wind tunnels, resistance measuring instruments, and strong object. Projects by design and test wind tunnel layout with Simulation of flow inside the tunnel with a program against Solidwork then test out the performance of a series of wind tunnel experiment. By testing the flow distribution inside the test Chamber, by changing the frequency, Hz Hz motor 4.87 19.3, 28.1, 33.6, Hz Hz Hz Hz 37.4, 41.7 from trials. It found that at low frequency (wind speed of 2 Hz or 4.87 m/s) is external distribution of speeds in irregular intervals. Which is not suitable to be put to the test, but when you add up the motor, frequency distributions, trends, the same speed throughout the entire frequency plane 19.3, 28.1, 37.4, 41.7 Hz suitable for test object model, which is based on the theory of design, wind tunnel studies?
