Abstract:

For the accurate analysis of hypersonic flows in wind tunnels, it is necessary to have precise measurements of the flow profiles to better understand the effects of short scale length turbulence. Current methods are lacking in time response, durability and reproducibility. The development of a durable, optically based sensor array capable of spatially resolved, real time pressure profile fluctuation measurements is proposed. From these measurements, thermodynamic fluctuations may be derived. The innovative features of the Multi-element Wind Tunnel Probe (MWTP) are two fold. First, the signals are based on optical effects for fast response and high resolution. Second, the transducer array will be fabricated using semiconductor manufacturing techniques and will be coated with diamond-like films for protection against high temperature, corrosive wind tunnel conditions. Design of a compact probe with multiple sensors is proposed in Phase I. Prototype demonstrations of the critical components will be done. Through the use of such a system, high temporally and spatially resolved measurements may be made in hostile environments. The importance of this innovation is its impact on aerospace research and in particular, as a powerful new diagnostic for wind tunnel studies.
