Icing can pose problems due to both accretions on aircraft aerodynamic surfaces as well as through shedding of large ice particles from aircraft surfaces. The shed ice causes damage by impacting downstream aerodynamic ...

A multi-entry experimental study was conducted to investigate the effects of roughness, simulated ice shapes, and various combinations of roughness and simulated shapes on aerodynamic performance of a reflection plane ...

With the world’s growing use of autonomous unmanned aerial systems (UASs), there is also a growing need for higher education to teach students how to design and implement the autopilot systems that many of these UASs depend ...

For this exploratory study, flight data of a Bell Model 205A-1 helicopter, flying under contract to the United States Forest Service, is analyzed to investigate its operational conditions. Usage of the helicopter, specifically ...

The methodology proposed in this research extends the current full-scale test approach based on the life factor and the load enhancement factor, and provides information necessary to define inspection intervals for composite ...

Structural elements are subjected to variable amplitude/spectrum fatigue loading where tensile overloads and compressive underloads may occur randomly. Depending on the magnitude of these loads, localized plastic deformation ...

The composite scarf joint configuration was utilized to simulate scarf-patch-repaired composite panels. An adhesive bonded scarf (tapered) joint was selected due to less peeling and shear stress over the bondline than with ...

Data obtained from digital flight data recorders installed on a fleet of 27 Beech 1900Ds are used to assess the actual operational environment of propellers on commuter aircraft. The data consists of 910 complete flights ...

A high-order finite difference solver was written to solve the incompressible Navier-Stokes (NS) equations and was applied to analyze the blood flow. First, a computer code was written to solve incompressible Navier- Stokes ...
