Structural optimization of high speed prop rotors including aeroelastic stability constraints

Level-Set Topology Optimization with Aeroelastic Constraints

Level-set topology optimization is used to design a wing considering skin buckling under static aeroelastic trim loading, as well as dynamic aeroelastic stability (flutter). The level-set function is defined over the entire 3D volume of a transport aircraft wing box. Therefore, the approach is not limited by any predefined structure and can explore novel configurations. The Sequential Linear Pr...

Structural/trim Optimization for Active Aeroelastic Wing Technology

A new process for concurrent trim and structural optimization of Active Aeroelastic Wing technology is presented. The new process treats trim optimization and structural optimization as integrated problems in the same mathematical formulation, in which control surface gear ratios are added as design variables to a standard structural optimization algorithm. This new approach is in contrast to m...

Speech recognizer optimization under speed constraints

We present an efficient algorithm for optimizing parameters of a speech recognizer aimed at obtaining maximum accuracy at a specified decoding speed. This algorithm is not tied to any particular decoding architecture or type of tunable parameter being used. It can also be applied to any performance metric (e.g. WER, keyword search or topic ID accuracy) and thus allows tuning to the target appli...
