TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
The objective of the proposed Phase II research effort is to develop advanced composite blankets for improved sound reduction in aircraft structures. Phase I successfully demonstrated the use of advanced blankets for sound transmission suppression and the applicability of the technology to aircraft interior noise control perpetuating a license agreement with a major U.S. Fortune 100 company to aggressively and expeditiously pursue product commercialization. The highest performing advanced blanket resulted in ~5 dB reduction in radiated power from an aircraft test panel. Reductions are broadband with an effective frequency range from approximately 100 to 1000 Hz resulting in decreased vibration and radiated acoustic levels across this range. The small 6-10% weight has acoustic benefits far greater than standard mass law effects. In Phase II attachment, temperature, and installation effects will be studied. Additionally, analytical design tools will be developed to automate the design process for practicing engineers making it possible to work from basic concepts and application requirements/specifications to achieve a final product which can be readily manufactured. Together the proven design concepts of Phase I and those proposed in Phase II represent the future in aircraft insulation in terms of acoustic performance, cost, weight, airframe integration, and passenger safety.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
NASA applications for advanced aircraft blankets with improved low frequency sound transmission attenuation compliment all aircraft and aviation agenda. The commercial potential is extensive throughout the US commercial and military markets resulting in an immediate economic competitive advantage of the US aircraft industry worldwide. They are cost effective, compact, lightweight, configurations not only satisfying the latest toxicity and flammability requirements, but benefiting from minimal integration issues due to similarities in shape and form of current blanket systems. We will work closely with our team members of NEVA Associates, Boeing Aircraft Company and the relevant blanket product supplier to determine the application requirements and limitations and product manufacturing parameters respectively.


Potential applications include NASA's Airspace Systems Program and Vehicle Systems Program. Both would benefit from overall reduction in cabin noise levels in aircraft transport vehicles. Additional applications include space vehicles and structures such as the Space Station and the Space Shuttle.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Successful execution of this project will result in an immediate and widespread application throughout the US commercial and general military industries. During Phase II, professional relationships will be built with material and blanket product suppliers to determine application requirements, limitations, and manufacturing parameters. SMD has discussed the details of the advanced concept with a major material manufacturer who currently supplies a variety of products to the US military for use in personnel protection and they have agreed to provide viability assessments and probable route to market for the most promising SMD candidate materials.

Market segments which will benefit from advanced blanket concepts are divided into military, architectural, industrial, commercial, and original equipment manufacturers (O.E.M.s). Some potential Non-NASA Applications include: (1) Military: Fabric Shelters, Naval Engine Noise, HVAC, Hummer Noise Control, Mobile Medical Units and Hospitals (2) Industrial: Manufacturing Fans, Blowers, Compressors, CNC's, HVAC (3) OEM: Trucks/Tractor Trailers, Commercial Floor Cleaners, Bank Equipment, Compressors.
