Designing quieter aircraft via acoustic simulation

2014-03-10
Greater fuel efficiency and low emission requirements have grown into such an urgent imperative in aircraft design that it often overshadows an equally significant factor in air travel—noise. Airbus shows that it’s possible to infuse acoustic simulation into design processes from beginning to end, giving engineers the acoustic simulation intelligence they need to create quieter aircraft, according to Free Field Technologies.

Enabling high-strength composites to reach their full potential

2014-03-10
The continued use of composite materials in aerospace has revealed other challenges that need to be addressed while the solutions to material and manufacturing cost are reduced. Before the widespread use of the material in transportation vehicles can be realized, safety challenges surrounding the material must be addressed.

Wärtsilä virtualizes marine engine design and testing

2017-05-31
The costs of building and running prototype engines are high, but they’re extremely daunting when each cylinder of a marine engine provides more than 1000 kW (1340 hp). That’s prompted Wärtsilä to invest heavily in hardware and software so modeling, simulation and virtual testing can be used to shorten development time and ensure that all design requirements are met.
