Reprint from the National Advisory Committee for Aeronautics report 181. This report is one of a series issued to aid the nation's war program. Information reviewed and reaffirmed 1965. Original report dated October 1941.
This research investigates shape optimization process, using b-spline models and panel methods, to achieve a high lift to drag ratio for an aerodynamic structure. This research is a proof of concept for further research in aerodynamic shape optimization. The coupled process, involving the design and optimization of a random shape,...
The analysis of a member carrying a combination of lateral and axial
loads (a "beam-column") is a problem of frequent occurrence in aircraft
structural design. This thesis presents the derivation and application
of the Polar method, both analytical and graphical. The method was first
suggested in Germany, several years later...

Micro air vehicles (MAV's) and small unmanned aerial vehicles (SUAV) are remotely piloted or autonomous aircraft with a take-off mass range between 50 g and few kilograms. These vehicles, as well as natural fliers such as bats and insects, utilize a variety of elastic wing structures including thin membranes. Over...

In conformity with advanced cockpit automation technology,
modern pilots have become airborne system managers
and have to satisfactorily manage complex sets of tasks to
complete a flight mission safely. Funk's (1991) normative
cockpit task management (CTM) theory defines CTM functions
as the initiation, monitoring, prioritization, allocating
of resources to, and...
The transfer of air travelers with disabilities between a mobility aid and an aircraft seat is a major source of injury for both the travelers and the airline personnel assisting in the transfer. The risk to both parties might be reduced through the biomechanical study of the transfer task. Such...
