INDUCED BY A PROPELLER WAKE

Award Year / Program / Phase: 1984 / SBIR / Phase II
Agency: NASA
Principal Investigator: Miguel C. Junger
Award Amount: $317,884.00
Abstract:
The advanced turboprop propulsion system offers possibility of poviding high subsonic flight speeds with fuel savings of15 percent compared with turbofan engines. passenger acceptance of these turboprops however requires that, interior noise levels be comparable with current turbofan powered… More

FEASIBILITY STUDY OF SCALED SURFACE SHIP MODEL FOR UNDEX EXPERIMENT

Award Year / Program / Phase: 1991 / SBIR / Phase I
Agency / Branch: DOD / NAVY
Principal Investigator: Miguel C Junger , Principal Investigator
Award Amount: $71,287.00
Abstract:
Shock vulnerability is an important design consideration for naval surface ships and submarines. although analytical procedures exist for evaluating the response to shock of elastic structures immersed inwater, verification is by means of shock tests. the current practice of shock testing full scale… More

ACTIVELY CONTROLLED HOOD FOR MACHINERY NOISE

Award Year / Program / Phase: 1993 / SBIR / Phase II
Agency: NSF
Principal Investigator: John E. Cole, Iii , Principal Scientist
Award Amount: $249,239.00
Abstract:
The proposed project will develop a concept for a machinery hood designed specifically to reduce noise using active control techniques. the structural design, a stiff "membrane", facilitates the use of active control based on minimizing the vibrational response of the enclosure surface. the… More

Proposal for analyzing energy dissipation mechanisms to improve fidelity of acoustic scattering predictions

Award Year / Program / Phase: 1993 / SBIR / Phase I
Agency / Branch: DOD / NAVY
Principal Investigator: Joel M. Garrelick
Award Amount: $50,213.00
Abstract:
Anticipated computing advances will greatly enhance the Navy's ability to compute submarine target strength. This capability can be an important diagnostic and design tool for T.S. control. While the complexity and size of the scattering problem makes it necessary to solve large sets of… More

ASSESSING ENVIRONMENTAL STRUCTURAL DAMAGE BY SONIC BOOMS

Award Year / Program / Phase: 1993 / SBIR / Phase I
Agency / Branch: DOD / USAF
Principal Investigator: Joel M Garrelick
Award Amount: $62,621.00

Feasibility study of scaled surface ship model for undex experiment

Award Year / Program / Phase: 1993 / SBIR / Phase I

ASSESSING ENVIRONMENTAL STRUCTURAL DAMAGE BY SONIC BOOMS

Award Year / Program / Phase: 1994 / SBIR / Phase II
Agency / Branch: DOD / USAF
Principal Investigator: Joel M Garrelick
Award Amount: $366,764.00
Abstract:
Assessing the environmental structural damage caused by U.S. Air Force supersonic flight operations is costly and time consuming. A contributing factor is the need for dedicated site flyovers. These are required to measure (i) the sonic boom induced pressure field on the structure, whihc owing to… More

Award Amount: $69,995.00
Abstract:
The primary aims of the proposed research are: (1) To develop asophisticated numerical model to explore the effects of cowlshape on the diffraction of the noise from rotors and stators;(2) to similarly predict the dissipative effects on net exteriorn

OPTIMALLY DIRECTIVE HYDROPHONE

Award Year / Program / Phase: 1994 / SBIR / Phase I
Agency / Branch: DOD / NAVY
Principal Investigator: John E. Cole, Iii
Award Amount: $60,814.00
Abstract:
The ability to survey ocean acoustic fields with directive hydrophones is advantageous for rejection of multipath arrivals, for resolving left-right ambiguity in towed arrays, and for improving the received signal-to-noise ratio. Under this Phase I study, a concept will be evaluated for achieving a… More

Feasibility study of scaled surface ship model for undex experiment

Award Year / Program / Phase: 1997 / SBIR / Phase II
