Research Institution
Complex Helicopter Analysis codes, such as the SEcond Generation Comprehensive Analysis System (2GCHAS), have been developed toprovide a common framework for interdisciplinary design and analysis of rotorcraft systems. A major limitation on the effectiveness of the second generation comprehensive analysis codes is the slow processing speed that results from the computational intensity of the analysis software. Advanced Rotorcraft Technology will utilize the Phase I effort to carefully define the specification for the parallelization opportunitites in 2GCHAS. In particular, the Phase I Base effort will include the following: 1) Port the most recent version of 2GCHAS Analysis on the Silicon Graphics Computer System. 2) Parallelize multicase analysis in 2GCHAS. 3) Design of parallelization of the assembly procedure. 4) Choose candidates for future parallelization in 2GCHAS. The Phase I Option effort will include the following: 1) Parallelization of the linearized analysis at azimuth level. 2) Parallelizatin of the linearization analysis at state perturbation level. The deliverables for the Phase I effort will include (1) Software units and a design document for 2GCHAS analysis software ported to the Silicon Graphics computer system. (2) Multicase analysis parallelization will be performed to demonstrate the application of parallelization techniques in the 2GCHAS analysis.
