NASA SBIR award for Rotorcraft On-blade Pressure and Strain Measurements TSI and the Department of Mechanical Engineering at the University of Maryland received a Phase I SBIR award on 17 November 2006 from the NASA SBIR program office to develop a Wireless Optical Pressure/Strain Sensor (WOPSS) system for helicopter on-blade pressure and strain measurements. According to project leader, Dr. Gang Wang, "Experimental measurements of rotor blades are important for understanding the aerodynamics and dynamics of a rotorcraft. This understanding can help in solving on-blade problems as well as in designing and optimizing the blade profiles for improved aerodynamics and noise attenuation in the next generation rotorcraft." The TSi WOPSS technology will exploit the inherent benefits of optical fiber sensors that will be embedded into composite aerospace structures, such as helicopter rotor blades. Fiber optic sensors will also be multiplexed, such that more than ten discrete sensors will be incorporated into one output lead, and interrogated by a single, low-cost electro-optical instrument. The Phase I SBIR project will conclude with an experimental rotor spin test demonstration of the WOPSS technology. The WOPSS technology will be applicable to a wide range of end-users in the defense, commercial, and industry sectors. TSi's WOPSS will be an integrated software/hardware product that will serve as an enabling technology for structural and condition-based maintenance practices. |
