DYNAMIC MODEL POSITIONING SYSTEM WITH ASSOCIATED PPIV FOR UNSTEADY AERODYNAMIC MEASUREMENTS
Abstract
The publically releasable proposal seeks to obtain a custom-made a dynamic positioning system for wind tunnel models and the associa,ted 6-component sting balance. The system will be augmented with high speed camera and microlens array to enable Time resolved Plen,optic PIV. The system will greatly improve the quality of the PIs experimental research facilities and will enhance his capabiliti,es to conduct fundamental studies of 3-D scaled models undergoing static and dynamic motions, including pitch, roll and yaw. The re,sults obtained using the requested system, with the PIs existing Time Resolved Particle Image Velocimetry (TR-SPIV) system, will en,able testing of scaled models to reveal physical mechanisms dominating the three-dimensional flow over scaled models under static an,d dynamic conditions. The system will be mainly used for an ONR-funded effort (in which Prof. Amitay is the PI), as well as other D,oD-funded projects by AFOSR (three-dimensional flow fields over swept and tapped finite span wings), and by ARO (control of reverse,flow over helicopter blades under static and dynamic pitch conditions). Moreover, the requested unique dynamic positioning system a,nd the instrumentation will enhance collaborations with other faculty members at RPI and in the USA, and will pave the way to obtain, future DoD-based funding. The requested system will enable a state-of-the-art tool for fundamental research of aerodynamic perform,ance enhancement of complex configurations. The system will be located in the Center for Flow Physics and Control (CeFPaC) at Renss,elaer Polytechnic Institute (RPI). The center has several facilities, including three wind tunnels (two low speed tunnels and one h,igh subsonic tunnel), and two water tunnels. In addition, the facility has two SPIV systems and a TR-SPIV system, three hot wire an,emometry units, and multiple steady and unsteady pressure sensors. The requested system will interface with one of the existing win,d tunnels at CeFPaCand will enhance the capabilities to conduct combined unsteady aerodynamic loads measurements with time-resolved,volumetric flow measurements during static and dynamic maneuvers. Also, the requested instrumentation has a strong educational comp,onent. Prof. Amitays group consists of 7 graduate students and 8 undergraduate students (per year) that are involved in 6 differen,t projects. The system will be used by those students and, as such, will enhance research-related education. In addition, the PI h,as been incorporating his research into the classroom, especially in undergrad courses such as Fluid Dynamics Lab and Fixed Wing Des,ign, as well as a grad course in Aerodynamic Flow Control. Demonstrations of the new system will be conducted to expose the student,s to advanced measurement techniques.
