Highly Elastic Strain Gage for Low Modulus Materials

New structural components on aerospace vehicles include highly elastic low Youngs modulus materials. These materials include Kevlar reinforced rubber and elastomers that inherently have a non-linear stress-strain relationship with extreme rupture strains, some greater than 500%. Current conventional foil strain gage technology is limited to 20% strains and inherently locally stiffens low modulus materials thus reducing strain transfer to sensor. With modification to a commercial medical sensor a highly elastic low modulus structural strain gage was developed and evaluated. Results from 16 sensors indicate potential use for elastic strain greater than 100%, with minimal localized stiffening. These initial tests indicate, when used with specifically designed constant current signal conditioning, accurate static strain measurements are achievable for ground test. In addition, a conceptual temperature-compensation method has been conceived to greatly reduce measurement error for future atmospheric flight applications in environments of minus 30F.


Ashish Hingle

Computer Information Systems

Ashish is studying CIS with an emphasis in Multimedia Application Development. He enjoys employing his skillset towards collating and discovering new and interesting trends amongst seemingly mundane data. He became a part of the NASA Technology Assessment program to branch out his talents and bring new light to the exciting technologies the program has to offer. Ashish hopes to gain experience in taking a technology from the younger stages all the way to its final commercialization and beyond.

Su Yeon

Biology and Zoology

Su Yeon is studying Biology with an emphasis in Zoology at Cal Poly Pomona. She joined the program because she realized it was a great learning opportunity to gain hands-on skills, learn about the commercialization process, and learn directly from NASA inventors and engineers. The majority of her studies have focused on life sciences, and this experience has taken her out of her comfort zone to work with both physical science and engineering concepts, while challenging her to think creatively. Su Yeon is currently pursuing a career in medicine. Medicine and technology are very intertwined, and she strongly believes that the skills learned will be helpful in her future career.

A Method for Delaying Laminar to Turbulent Transition on Swept Wings and Surfaces

Boundary layer cross flow is a dominant transition mechanism on swept wings at flight Reynolds numbers. Other transition mechanisms (such as attachment line transition, and Tollmein-Schlicting instabilities) can be managed by design, but managing cross-flow transition has been elusive. The only viable method, so far, has been using a method called “Distributed Roughness Elements” or DRE’s. DRE’s are very small roughness elements placed just downstream of the leading edge and attachment line. DRE’s are designed to amplify a subcritical cross-flow wave as a means of attenuating what will become the dominant wave. This allows the flow to maintain a laminar boundary layer for a much longer chordwise extent than with the unmodified flow. Extending laminar flow can significantly reduce drag which consequently reduces fuel burn and increases range. While DRE’s have been shown to work, so far the limitations have prevented their application on a full-scale aircraft. One limitation is that any particular DRE pattern is effective only for very limited conditions (i.e. point design). Thus to be more effective the DRE’s would need to active in the sense that the elements would need to change to varying conditions. The current innovation has been shown to be able to produce a cross flow within the boundary layer.

Marion Barleta

Marketing with an Emphasis in Market Research

Marion Barleta is pursuing a degree in Marketing with an emphasis in Market Research. He is a graduating senior who aspires to start his own business within the consulting and production industry. After observing the opportunity to refine his business sense and market research expertise, he joined the NASA Technology Assessment Program to utilize his knowledge in an applicable area. He hopes to gain better insight of industries he was not originally versed in and gain insight of how companies can use innovation in technology to compete in the market.
