AI Technical Summary

Benefits of technology

This patented technology allows for precise measurement of sub-subsonic flows without affecting other parts or causing damages during testing. It also provides an efficient way to adjust the amount of fluid being injected into different areas within the tested part while maintaining its stability. Additionally, it uses a special design that improves the durability of the weatherproof membrane over which the water passes when there are no rainwater conditions. Overall, this new technology simplifies the process of controlling fluids inside wind tunnels and ensures stable operation under various environmental factors such as temperature changes.

Problems solved by technology

This patented describes how accurate testing can occur for airplanes at different speeds depending on their specific needs. By regulating both the amount of intake fluid entering the engine's fan case (flow) and the size of an exit port(open), the system ensures consistency between tested conditions and results from various factors like altitude, atmospheric temperature, humidity levels, etc., which may vary over short periods of time. Additionally, there has been research into improving the performance of certain types of flight vehicles without compromising safety standards. These issues include reducing noise emissions caused by turbulence within the vehicle cabin, increasing fuel efficiency, minimizing wear and tear damage, and enhancing passenger comfort level. Overall, these technical problem addressed in the patents involve accurately measuring and controllably manipulating flows in realistic environments while maintaining strict requirements imposed upon them.
