PROJECT SUMMARY

Contract Id:

NAS 4 50075

Proposal Number:

03.05-4434

Project Title:

AUTOMATED HOT-WIRE ANEMOMETER INSTRUMENTATION SYSTEM FOR IN- FLIGHT VELOCITY FLOW FIELD MEASUREMENTS

Technical Abstract:

An automated hot-wire anemometer instrumentation system will be developed for in-flight measurements of three-dimensional boundary-layer velocity flowfields on aircraft wing surfaces. The proposed system automatically adjusts to changes in flight environment, be relatively immune to Radio Frequency Interference, with capability to measure mean and fluctuating components and resolving mass-flow and temperature components as well. The proposed system will be particularly suitable for conducting high-speed flight tests to establish bench mark data for CFD code validation. Such an instrument will be invaluable for flow diagnostics for transition detection, investigation of boundary-layer instability, flow separation, shock, and other critical aerodynamic flow characteristics.

Potential Commercial Applications:

A routine flight test instrument will be available for validating CFD codes. Such an instrument will enhance understanding the flowfields for design of better performance aircraft which is continuously sought which in turn will produce safer and economical flight vehicles. The instrument can also be used for atmospheric turbulence measurements in addition to highly productive ground based tests like in wind tunnels as well.
