Physics-Based Probabilistic Design Tool with System-Level Reliability Constraint

Phase 2 SBIR

Agency: National Aeronautics and Space Administration
Topic: 06-2
Budget: 01/01/06 - 12/31/06
PI: Dr. Vinod K. Nagpal

The work proposed herein would develop a set of analytic methodologies and a computer tool suite enabling aerospace hardware designers to rapidly determine optimum risk-constrained designs subject to multiple physics-based uncertainties in applied loads, material properties, and manufacturing processes. This means that the design process no long...

Physics-Based Probabilistic Design Tool with System-Level Reliability Constraint

Phase 1 SBIR

Agency: National Aeronautics and Space Administration
Topic: 05-1
Budget: 01/01/05 - 12/31/05
PI: William Strack

The work proposed herein would establish a concurrent design environment that enables aerospace hardware designers to rapidly determine optimum risk-constrained designs subject to multiple uncertainties in applied loads, material properties, and manufacturing processes. This means that the design process no longer would consist of a sequence of ...

High Toughness Light Weight Pressure Vessel

Phase 1 SBIR

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

Proposed is a pressure vessel with 25% better Fracture Strength over equal strength designed Fiberglass to help reduce 10 to 25% weight for aerospace use. Phase I is a proof-of-concept to make a 4? diameter x 24? long cylindrical vessel. Phase II will make 12? or larger diameter x 48? long vessels. The vessel will be used to store compressed gas...

Probabilistic Design Tool for Small Turbine Engine High Cycle Fatigue (HCF) Life

Phase 2 SBIR

Agency: Army
Topic: A01-067
Budget: 01/29/03 - 01/29/05
PI: Dr. Vinod K. Nagpal

This project will significantly improve the accuracy of high cycle fatigue (HCF) life predictions of centrifugal compressors used in small gas turbine engines. This will be done by developing a probabilistic reduced-order model HCF life prediction computer code that captures the random blade mistuning effects present in actual hardware. Mistunin...

Probabilistic Design Tool for Small Turbine Engine High Cycle Fatigue (HCF) Life

Phase 1 SBIR

Agency: Army
Topic: A01-067
Budget: 01/25/02 - 01/18/03
PI: Dr. Vinod K. Nagpal

This project will significantly improve the accuracy of small turbine engine high cycle fatigue (HCF) life predictions by including the phenomenon of bladed disk mistuning in the structural analysis modeling. This will be done by developing reduced-order models and integrating them into a probabilistic structural analysis computer code. The red...
