Description

NASA Langley Research Center in Hampton, VA solicits interest from companies
interested in obtaining license rights to commercialize, manufacture and market
the following technology. License rights may be issued on an exclusive or
nonexclusive basis and may include specific fields of use.

THE TECHNOLOGY:

NASA Langley researchers have developed a novel noncontact method to
identify internal damage inside structures. Air Coupled Acoustic Thermography
(ACAT) was originally developed for damage identification in honeycomb
sandwich structures but can also be applied to other systems. ACAT uses
pulsed acoustic waves to generate movement and vibrations in areas of
honeycomb structures that exhibit weakness or stress. These vibrations
generate temperature differentials that can be visualized via thermography and
essentially allow more exact identification of damaged regions. ACAT provides
several advantages over techniques used for similar purposes such as
ultrasound or vibrothermography in that the excitation source does not need to
be physically coupled to the substrate of interest. This advantage allows ACAT
to detect damage in curved surfaces and mitigates the risk of damaging the
substrate at the coupling point. ACAT has been demonstrated to accurately
visualize internal core damage as well as damage nearer to the structure's skin.

To express interest in this opportunity, please respond to Sean Sullivan,
Research Triangle International (RTI), at: NASA Langley Research Center,
Strategic Relationships Office (SRSO), 17 West Taylor St., Mail Stop 218, Building
1212, Room 110 Hampton, Virginia, E-mail: Sean.D.Sullivan@NASA.gov, or
phone: 757-864-5055. Please indicate the date and title of the FBO notice and
include your company and contact information.

RTI is responsible for aggregating and acknowledging all responses. These
responses are provided to members of NASA Langley's Innovative Partnerships
Office within the SRO for the purpose of promoting public awareness of our
technology products, and conducting preliminary market research to determine
public interest in and potential for future licensing opportunities. If direct
licensing interest results from this posting, SRO will follow the formal licensing
process of posting in the Federal Register as required. No follow-on
procurement is expected to result from responses to this Notice.
