Phase 1 SBIR

Agency: National Aeronautics and Space Administration
Topic: 12-1-A3.02
Budget: 01/01/13 - 12/31/13

Aerospace structures are often subjected to a broad spectrum of mechanical and/or aerodynamic excitations and, therefore, there is a real need for the development of a modeling technique which can be used for the vibroacoustic analysis, with high fidelity and adequate spatial and spectral resolutions, of complex systems over the entire frequency...

Phase 1 SBIR

Agency: National Aeronautics and Space Administration
Topic: 10-1-A2.03
Budget: 01/01/11 - 12/31/11

In many situations, aerospace structures are subjected to a wide frequency spectrum of mechanical and/or acoustic excitations and therefore, there is a need for the development of numerical modeling techniques that are applicable for the resolution of dynamic response of complex systems spanning the entire frequency spectrum. Further, the modeli...

Phase 2 STTR

Institution: University of Michigan

Agency: Air Force
Topic: AF08-T025
Budget: 01/11/10 - 01/11/12

ABSTRACT: This proposal is concerned with the development of a novel failure initiation and progressive failure analysis modeling method for advanced composite structures, including the analysis of selected structural joints utilizing a statistically based micromechanics model embedded in a 3D non-linear finite element code. The method accounts...

Phase 1 SBIR

Agency: National Aeronautics and Space Administration
Topic: 09-1
Budget: 01/01/09 - 12/31/09

In many situations, aerospace structures are subjected to a wide frequency spectrum of mechanical and/or acoustic excitations and therefore, there is a need for the development of numerical modeling techniques that are applicable for the resolution of dynamic response of complex systems spanning the entire frequency spectrum. However, the dynami...

Phase 1 STTR

Institution: University of Michigan

Agency: Air Force
Topic: AF08-T025
Budget: 08/01/08 - 03/01/09

This proposal is concerned with the development of a novel failure initiation and progressive failure analysis (PFA) modeling method for advanced composite structures. The laminate is modeled as a collection of degrading lamina within the framework of lamination theory and executed using user defined subroutines through a commercial finite eleme...

Phase 2 SBIR

Agency: National Aeronautics and Space Administration
Topic: 07-2
Budget: 01/01/07 - 12/31/07

Communities near airports are often exposed to high noise levels due to low flying aircraft in the takeoff and landing phases of flight. Propulsion source noise is the major contributor to the overall noise level. The noise generation mechanisms for a typical turbofan engine are complicated, which makes it a significant challenge to identify the...

Phase 1 SBIR

Agency: National Aeronautics and Space Administration
Topic: 06-1
Budget: 01/01/06 - 12/31/06

Noise has become a primary consideration in the design and development of many products, particulary in aerospace, automotive and consumer product industries. Communities near airports are often exposed to high noise levels due to low flying aircraft in the takeoff and landing phases of fligh and the major contribution to the overall noise is co...

Phase 2 SBIR

Agency: National Aeronautics and Space Administration
Topic: 05-2
Budget: 01/01/05 - 12/31/05

It is proposed to develop and implement a computational technique based on Energy Finite Element Analysis (EFEA) for interior noise prediction of advanced aerospace vehicles that will expand NASA's noise prediction capability at the early stage of design process. In many situations, aerospace structures are subjected to high frequency mechanical...

Phase 1 SBIR

Agency: National Aeronautics and Space Administration
Topic: 04-1
Budget: 01/01/04 - 12/31/04

Evaluation and enhancement of the acoustical performance of turbomachinery requires knowledge of the acoustic sources. However, the noise generation mechanisms associated with turbomachinery are complex and as result it is not easy to identify these noise sources. The development of an integrated experimental/numerical technique that is based on...

Phase 1 SBIR

Agency: National Aeronautics and Space Administration
Topic: 04-1
Budget: 01/01/04 - 12/31/04

Prediction and enhancement of vehicle interior noise due to high frequency excitation, based on computer simulation, allows the application of the technology at the early stage of design process thereby improving the quality and reducing the cost. Traditionally, Statistical Energy Analysis (SEA) has been used for this purpose. Modeling of SEA is...
