Large-Scale Dynamic System Testing Tower
The Large-Scale Rotor Testing Facility was designed to support active flow control experiments on large blades with embedded actuators and sensors. Currentlly it is capable of accomodating blades with rotor diameters of 2-3 meters driven by a brushless motor rated at 8.5 kW of power. The custom rotor head and drive mechanics can be mounted to allow the system to operate in helicopter mode, or in energy capture wind turbine mode (for outdoor operation) with the motor acting as a generator. The tower contains an ATI Theta 6-component load cell just below the rotor assembly and is capable of measuring forces up to 2500 N with 1/4 N resolution and torques of 120 N-m with 1/80 N-m resolution. A 220V high power supply controlled by the computer is capable of deliving up to 10 kW of power to the motor. Finally, the facility contains an NI X Series DAQ (32 AI, 48 DIO, 4 AO) system with 1.25 MS/s sampling rate to acquire load cell/ blade sensor data and activate blade actuators.
Low-Speed Thermal Stratified Wind Tunnel
The Low-Speed Wind Tunnel with capability for thermal stratification in the test section is designed for fundamental and applied low Reynolds number studies such as: (i) the interaction of a synthetic jet(s) in a flat plate or airfoil and the cross flow, (ii) smooth and rough surface boundary layers with thermal stratification, (iii) and active flow control and unsteady aerodynamics of fixed and flapping wings for micro aerial vehicle (MAV) applications. The test section contains dimensions of 1.5 ft by 1.5ft with a 4 ft length. The maximum flow speed is 40 m/s at a turbulence level of less than 0.3%. The facility includes a wall-mounted ATI 6-component load cell, array of pressure transducers, and an NI DAQ system for data acquisition.
Small-Scale Dynamic System Testing Tower
The Small-Scale Dynamic System Test Tower was designed to test the performance of small rotor-motor systems (i.e. thrust, torque, power) and UAV related dynamic compoments under unsteady loads. The 3 ft tower contains an ATI Gamma 6-component load cell capable of measuring forces 400 N with 1/20 N resolution and torques of 10 N-m with 1/800 N-m resolution. A power supply capable of delivering up to 1.2 kW is controlled with Matlab and the load cell data and power measurements are acquired with an NI X Series DAQ (16 AI, 24 DIO, 2 AO) at 500 kS/s sampling rate.
