An Investigation of the Dynamic Effects of Flap Deflection on the Aerodynamic Characteristics of an Airplane Wing Using Computational Fluid Dynamics
<p>Flaps are used to increase an airplane's lift and to adjust its stability and maneuverability. This study shows an application of STAR-CD, a commercial computational fluid dynamics (CFD) software, to an investigation of the dynamic effects of flap deflection on the lift, drag and moment …

An integrated strategic sourcing process for complex systems
… sourcing decision process at Boeing Commercial Airplanes. A discussion-based strategic sourcing process utilizing a holistic range of factors is proposed to test whether an expensive, complex, and integrated system like a composite airplane wing should be outsourced or if it should be designed …

Development of a Sensor for Inflight Detection of Three-Dimensional Flow Separation on a Wing
… capable of detecting flow-field separation on an airplane wing during routine flight operations. A sensor of this type could lead to both improved flight safety and increased performance. It would also contribute to future separation control technologies. A new idea is presented for a sensor that …

Design of a Pneumatic Tool for Manual Drilling Operations in Confined Spaces
… is to back-drill pilot holes inside a commercial airplane wing. It is lightweight, and a “locator pin” enables the operator to align the drill over a pilot hole. A suction pad stabilizes the system, and an air motor and flexible drive shaft power the drill. Two testing procedures were performed to …

An Ameliorated Prediction of the Empennage In-Flight Gust Loads for a General Aviation Aircraft
<p>Airplanes often operate beyond their original design load profiles. Aviation opens so many new possibilities and wide variety of possible activities that it is hard for designers to foresee all loading spectra that the airplane structure will experience throughout its life. Nevertheless, the …
