Adhesively bonded joints are used on numerous applications involving light-weight composite materials. Consequently, the successful modeling and subsequent analysis of bonded joints involving more than one adherend ...

In this thesis, wing-body junction flow is studied parametrically using computational fluid dynamics (CFD) in an attempt to understand the effects of junction flow on aircraft drag, with a focus on application to large ...

Applications for Unmanned Aerial Vehicles (UAV) and, specifically, Micro Aerial Vehicles (MAV) are increasing. As is the case for all aircraft, propulsion plays a significant factor in overall vehicle performance. Most ...

The recent increase in the development of UAV’s and MAV’s has created a strong demand for small propeller performance data. Propeller performance is critical to the success of these aircraft and guaranteed performance ...

Recent flight test experience and simulator studies have shown that the traditional test for static lateral stability, the steady heading sideslip, in some cases may be overly conservative and place unnecessary restrictions ...

The stress-strain behavior and failure of composite materials are strain rate sensitive, and influenced by the dimensions of the structure. To elucidate the combined effects of scaling and strain rate on the strength of ...

Composite materials together with adhesive-bonding have been increasingly used in the aviation industry. Delamination is among the critical failure modes in fiber-reinforced laminated composite structures including ...

Due to current economic conditions, aircraft are being operated to their design life and often beyond. In order to assess the true condition of these aging aircraft structures, structural teardowns have become more common ...

The transverse compressive behavior of honeycomb cores has been widely exploited for energy absorption applications in the automotive and aerospace industry. The energy absorption in honeycomb cores with thin reinforced ...

Results from a research program to investigate the long term effects of through-the-thickness fastener clamp-up force (preload) relaxation on the strength of mechanically fastened joints for two graphite/thermoplastic composite ...
