Aircraft Trajectory Optimization for European Flights: Assessment of the trajectory variability considering a trade-off between operating costs and climate impact

In order to reduce the climate impact induced by the aircraft industry, the variability between cost optimized and climate optimized flight trajectories was evaluated. This was done to establish how the climate impact reduction affects the operating costs and vice versa. To evaluate the climate impact of air traffic, a climate-chemistry model...

Structural Performance of Fiber-Placed, Variable-Stiffness Composite Conical and Cylindrical Shells

The use of fiber-reinforced composites in aerospace structures has increased dramatically over the past decades. The high specific strength and stiffness, the tailorability, and the possibilities to integrate parts and reduce the number of fasteners give composites an advantage over metals. Automation of the production process enables large...
