Probabilistic Assessment of Handling Qualities Constraints in Aircraft Preliminary Design
(Georgia Institute of Technology, 1998-01)
A method is introduced and demonstrated which uses parametric stability derivative data (in the form of regression equations) and probabilistic analysis techniques to evaluate the impact of uncertainty on the handling ...
A Bi-Level optimization approach for technology selection
(Georgia Institute of Technology, 2002-09)
Technology selection is a crucial step in the process of aircraft design. If the performance and economic requirements are not fulfilled for any combination of the design variables, new technologies need to be infused in ...
A Stochastic Design Approach for Aircraft Affordability
(Georgia Institute of Technology, 1998-09)
A novel approach to assessing aircraft system feasibility and viability over time is presented, with special emphasis on modeling and estimating the impact of new technologies. The approach is an integral part of an overall ...
Viable Designs Through a Joint Probabilistic Estimation Technique
(Georgia Institute of Technology, 1999-10)
A key issue in complex systems design is measuring the 'goodness' of a design, i.e. finding a criterion through which a particular design is determined to be the 'best.' Traditional choices in aerospace systems design, ...
An Integrated Approach to Military Aircraft Selection and Concept Evaluation
(Georgia Institute of Technology, 1995-09)
The design (or evaluation) of military aircraft, by nature, is a process consisting of conflicting goals and objectives at the conceptual, preliminary, and detailed level. Affordability, mission capability, availability ...
Uncertainty Modeling and Management in Multidisciplinary Analysis and Synthesis
(Georgia Institute of Technology, 2000-01)
The complex, multidisciplinary nature of aerospace design problems, as well as the requirement to examine life-cycle characteristics, have exposed a need to model and manage uncertainty. In this paper, a formal approach ...
Determination of System Feasibility and Viability Employing a Joint Probabilistic Formulation
(Georgia Institute of Technology, 1999-01)
The present paper outlines a method for probabilistic multi-criteria decision making. Recognizing the limitations of traditional probabilistic methods in accounting for multiple decision criteria in conceptual or preliminary ...
A New Approach to Integrated Wing Design in Conceptual Synthesis and Optimization
(Georgia Institute of Technology, 1996-09)
Design-oriented analysis has become increasingly important as more and more problems traditionally solved in isolation are being approached from a multidisciplinary point of view. One such problem is the aeroelastic ...
Generating Dynamic Models Including Uncertainty for Use in Aircraft Conceptual Design
(Georgia Institute of Technology, 1997-08)
Accurate stability and control derivative information is essential to the configuration designer. As new, non-conventional aircraft are being designed, however, the trusted stability and control estimates usually used in ...
A New Model for the Aerospace Design Process Based on a Control System Analogy
(Georgia Institute of Technology, 2000-09)
A novel approach to the modeling and control of aerospace system design problems is presented. By integrating recent advances in probabilistic robust design and technology assessment methods with a traditional control ...
