MRI: Development of a Next Generation Polysonic Wind Tunnel for Transformative Active Control Technologies and Non-Intrusive Flow Diagnostics

这个主要研究仪器（MRI）开发项目是一个新的多晶硅风洞排污设施，由压缩空气产生和储存系统、测试部分和排气系统组成。风洞的典型特征是其速度范围和测试部分的大小。该设施的测试部分为12英寸x 12英寸x 24英寸，马赫数范围为0.2至5，最大雷诺数能力约为2000万/英尺。这个设施将大到足以对工业有用，确保其长期有效使用，但小到足以在大学有效地运作。它将用于开发创新的、实用的主动流量和噪声控制技术以及先进的诊断技术，以研究高速飞行器的设计和基本问题。它将结合独特的设计特点，具有低测试段噪声和广泛的流体诊断光学通道。多晶硅风洞将创造一个独特的共享资源，a)在气体动力学、材料科学和其他领域取得根本性进展；B)发展变革性的流量控制技术；c)吸引、教育并帮助留住多样化的工程师和科学家，包括我们合作机构中代表性不足的少数族裔。因此，该设施将产生关键知识，同时大大加速导致下一代设计的变革性研究。它还将利用和增加佛罗里达先进航空推进中心的资源，这是一个由佛罗里达州立大学领导的多所大学全州卓越中心。

This Major Research Instrumentation (MRI) development project is for a new polysonic wind tunnel blowdown facility consisting of a compressed air generation and storage system, test sections, and exhaust system. A wind tunnel is typically characterized by its speed range and the size of its test section. The facility has a 12-in x 12-in x 24-in test section with a Mach number range of 0.2 to 5 with a maximum Reynolds number capability of roughly 20 million/foot. This facility will be large enough to be useful to industry, ensuring its long-term, efficient use but small enough to be efficiently operated in a university. It will be used to develop innovative, practical active flow and noise control techniques and advanced diagnostics to study the design of, and fundamental problems in, high-speed flight vehicles. It will incorporate unique design features with low test-section noise and extensive optical access for flow diagnostics. The PolySonic Wind Tunnel will create a unique shared resource to a) produce fundamental advances in gas dynamics, material science and other areas; b) develop transformational flow control technologies; and c) attract, educate, and help retain a diverse pool of engineers and scientists, including underrepresented minorities from our partner institutions. The facility will thus produce critical knowledge while dramatically accelerating transformative research leading to next-generation designs. It will also leverage and augment the resources of the Florida Center for Advanced Aero-Propulsion, a multi-university, statewide Center of Excellence, led by Florida State University.
