Inline Caster

Hamilton Standard custom engineered an all-stainless inline caster for a major aerospace supplier. The aerospace company ordered two of these special casters designed for a clean-room environment, each with a carrying capacity of 15,500 lb. The caster stands 10-1/8-in tall and 21-in long, and is equipped with two 8-in-diameter by 2.2-in-wide double flanged track wheels. Four 40-mm double sealed precision stainless steel ball bearings were press fit into each wheel with 1-1/4-in axles.

Designing Quieter Aircraft via Acoustic Simulation

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.
