Practical Airplane Quieting

Spline Techniques for Generating Airplane Wings with Practical Applications

In the present paper we describe the CAGD part of an effort that aimed at the unification of the whole geometric preprocessing that preceded the wind tunnel readings with a realistic air-plane wing model in a recent research project. This preprocessing includes the automated generation of the CAD models which were used for the manufacturing of the multi-parted wing-fuselage configuration and th...

Conceptual Blending and Airplane Navigation

Fauconnier and Turner’s conceptual blending theory (1998) has been used to analyze many types of cognitive phenomena, particularly the role blending plays in language comprehension. In this paper we illustrate how blending also has a role in mediating expert performance, such as understanding the meaning of a chart or a navigation display. Pilots use blends to assess flight situations, predict ...

A quieting ocean: unintended consequence of a fluctuating economy.

Simultaneous long-term monitoring of underwater sound and ship traffic provided an opportunity to study how low-frequency noise correlated with ocean-based commercial shipping trends. Between 2007 and 2010 changes in regional shipping off southern California occurred as a consequence of economic and regulatory events. Underwater average noise levels measured before and during these events showe...

Parallel Numerical Airplane Wing Design

A parallel numerical optimization method for the airplane wing design has been established The extension of traditional Evolution Strategies by new and alterna tive methods combined with a load management for parallel processes leads to the MEPO optimization system The concept of the system allows bene cial usage of parallel processing features for running the optimization algorithms as well as...
