A Virtual Airplane for Fear of Flying Therapy

Fear of flying is a serious problem that affects millions of individuals. Exposure therapy for fear of flying is an effective therapy technique. However, exposure therapy is also expensive, logistically difficult to arrange, and presents significant problems of patient confidentiality and potential embarrassment. We have developed a virtual airplane for use in fear of flying therapy. Using the ...

Flying bicycles : How the Wright brothers invented the airplane

This paper explores the ways in which Wilbur and Orville Wright thought as they tackled the problem of designing and constructing a heavierthan-air craft that would fly under its own power and under their control. It argues that their use of analogy and their use of knowledge in diagnostic reasoning lies outside the scope of current psychological theories and their computer implementations. The...

Flying Wing versus Conventional Transport Airplane: the 300 Seat Case

Unconventional aircraft are being studied by the aeronautical engineering community with accelerated interest and effort to improve economic efficiency and to overcome operational and infrastructure-related problems associated to the increasing size of transport airplanes. The objective of the research reported here is to assess the technical feasibility and operational efficiency of a medium s...

Airplane Ground Vibration Testing – Nominal Modal Model Correlation

SOUND AND VIBRATION/NOVEMBER 2002 A brief overview is given of transport airplane ground vibration testing (GVT) at Boeing Commercial Airplane Group. A GVT is a modal test conducted for the purpose of validating and improving a structural dynamic model of the airplane. A “small signal” model is quickly and conveniently identified from multi-input burst random excitation. Sine excitation is used...
