Phase 2 SBIR

Agency: Air Force
Topic: AF01-037
Budget: 09/18/02 - 12/30/05

This research will establish the feasibility of new control system optimization techniques to address complex vibration control problems within the constraints of limited cost, volume, and weight. Several methods are being investigated and developed to predict the phase of response in a reverberant multiple degree of freedom (MDOF) system, with...

Phase 2 SBIR

Agency: Air Force
Topic: AF01-022
Budget: 09/13/02 - 12/13/04

The Phase II effort will develop and test an optimized fairing blanket treatment based on heterogeneous material design for improved low-frequency performance and improved weight and/or volume to acoustic performance ratios than current, conventional blankets. The material modeling code validated in Phase I will be refined and an optimization pr...

Phase 1 SBIR

Agency: Air Force
Topic: AF01-022
Budget: 05/27/01 - 05/08/02

In Ph.I Vibro-Acoustic Sciences will extend and apply its acoustic modeling technology to investigate an entirely new class of blanket construction - "heterogeneous construction" - as a means to achieve better low- and mid-frequency attenuation of acoustic levels in launch vehicle fairings. Candidate heterogeneous blanket concepts include Prof. ...

Phase 1 SBIR

Agency: Air Force
Topic: AF01-037
Budget: 04/27/01 - 04/08/02

In Phase I, Vibro-Acoustic Sciences will extend its proprietary Statistical Energy Analysis (SEA) code to estimate the statistics of phase for single input - single output transfer functions between launch vehicle fairing and payload acoustic volume. This is an extension of the preliminary research for AFRL on the same topic, conducted in 2000 b...

Phase 2 SBIR

Agency: Air Force
Topic: AF00-041
Budget: 04/23/01 - 07/27/03
PI: Steven O

This Phase II will develop a cost- and weight-effective means for achieving an improved low- and mid-frequency acoustic environment in payload fairings for rockets at lift-off. The solution to be developed will consist an active noise control system with an optimum selection of SmartFoam, distributed active vibration absorbers (DAVAs) and acoust...

Phase 1 SBIR

Agency: Air Force
Topic: AF00-038
Budget: 04/28/00 - 04/02/01

This SBIR project will develop critical vibroacoustic and shock analysis methods that are needed by the Air Force for a more rigorous and standardized approach to the prediction of launch environments for spacecraft, launch vehicles and flight hardware. The new methods developed will all build on existing prediction numerical analysis capabiliti...

Phase 1 SBIR

Agency: Air Force
Topic: AF00-041
Budget: 04/28/00 - 04/02/01

This project will construct a conceptual yet practical design of an active-passive control system to cancel broadband acoustic noise in launch vehicle payload fairings with an emphasis on the very low frequencies where past methods have proved unsatisfactory. A thorough review of active-passive technologies will be conducted to determine those t...

Phase 1 SBIR

Agency: Navy
Topic: N98-092
Budget: 07/13/98 - 01/12/99

This project aims to incorporate airborne noise & vibration control in the overall ship design and construction process to improve the noise & vibration environment on all vessels while reducing the associated adverse impacts on space, weight, m The proposed solution is a computerized noise prediction tool which will involve a new integration o...
