Improved testing methods for measurement of extension-twist coupling
(Georgia Institute of Technology, 1999-05)
Rotorcraft trim by a neural model-predictive auto-pilot
(Georgia Institute of Technology, 2005-04-14)
In this work we investigate the use of state-of-the-art tools for
the regulation of complex, non-linear systems to improve the
methodologies currently applied to trim comprehensive virtual
prototypes of rotors and ...
Maneuver Trim Optimization Techniques for Active Aeroelastic Wings
(Georgia Institute of Technology, 2000-04)
A new method for performing trim optimization of Active Aeroelastic Wing (AAW) technology is presented. The method is based on posing the trim problem as a linear program and solving it with the simplex method. Trim ...
Aeroelastic Analysis of a Composite Wingbox with Varying Root Flexibility
(Georgia Institute of Technology, 2000-04)
The research looked into the aeroelastic properties and modal response of a composite rectangular wingbox. This research attempted to assess the sensitivity of the flutter speed, divergence speed and modal response when ...
An Integrated Trim And Structural Design Process For Active Aeroelastic Wing Technology
(Georgia Institute of Technology, 2001-04)
A new method for concurrent trim and structural optimization of Active Aeroelastic Wing technology is presented. The new process treats trim optimization and structural optimization as an integrated problem in the same ...
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 ...
Aeroelastic Tailoring of a Civil Tiltrotor Configuration
(Georgia Institute of Technology, 1995-01)
Progress in establishing an analysis package and design/optimization framework for preliminary design of a civil tiltrotor aircraft is reported. Updates to the sizing/performance program VASCOMP and Equivalent LAminated ...
Application of a State-Space Wake Model to Tiltrotor Wing Unsteady Aerodynamics
(Georgia Institute of Technology, 1994-02)
The Peters/He Finite State Wake Model is described in its application to fixed wing aerolasticity. Expressions for coupling this model with a wing, aerodynamically represented by a flat plate with a trailing edge flap, are ...
Robust Design for Aeroelastically Tailored/Active Aeroelastic Wing
(Georgia Institute of Technology, 1998-09)
A study of multidisciplinary design concerning the incorporation of aeroelastic tailoring, control surface blending, and active aeroelastic wing concepts is presented. The design process incorporates response surfaces, ...
An Approach to Tiltrotor Wing Multidisciplinary Optimization through Increased Productivity
(Georgia Institute of Technology, 1992-09)
The paper describes one way to approach the multidisciplinary task of optimizing a tiltrotor wing structure which is equipped with an active flutter suppression system. Objective function is a productivity index, as a ...
