چکیده

An objective of the High Performance Computing and Communication Program at the NASA Langley Research Center is to demonstrate multidisciplinary shape and sizing optimization of a complete aerospace vehicle configuration by using high-fidelity finiteelement structural analysis and computational fluid dynamics aerodynamic analysis in a distributed, heterogeneous computing environment that includes high performance parallel computing. A software system has been designed and implemented to integrate a set of existing discipline analysis codes, some of them computationally intensive, into a distributed computational environment for the design of a high-speed civil transport configuration. The paper describes both the preliminary results from implementing and validating the multidisciplinary analysis and the results from an aerodynamic optimization. The discipline codes are integrated by using the Java programming language and a Common Object Request Broker Architecture compliant software product. A companion paper describes the formulation of the multidisciplinary analysis and optimization system.

Response Surface Methodologies for Low-Boom Supersonic Aircraft Design using Equivalent Area Distributions

The use of response surface models (also known as surrogate models) to describe the performance of aerospace systems within a given design space is by now fairly well established in the MDO community. Despite such widespread use, surrogate-based optimization techniques can incur significant computational expense when high-dimensional spaces must be modeled. In this paper we describe an adaptive...
