New Unmanned Air System Tested on USS Coronado

Researchers from the U.S. Naval Research Laboratory (NRL) successfully tested their Nomad flight vehicle off of USS Coronado (LCS 4) recently. This test demonstrated the Nomad’s upgraded launch and control capabilities as well as a new recovery capability by launching multiple vehicles in quick succession, conducting formation flying operations, and recovering all vehicles sequentially onboard the USS Coronado.

Quality Control for Additive Manufacturing Parts Using Non-Destructive Testing

Additive Manufacturing (AM) is growing in importance as a fabrication process for the space industry, enabling weight and cost savings through optimized designs for components. The use of AM gives aerospace engineers an alternative to more traditional manufacturing processes, but also retains the challenge of producing parts without defects. These problems can be approached using nondestructive methods such as X-ray Computed Tomography (CT) and Finite Element Modelling (FEM) to inspect geometries and quantify the impact of defects on the mechanical properties of a part, taking into account factors such as internal stress from metal cooling during fabrication.

Developing a Conformal Coating Process for Aerospace Applications

Conformal coatings protect electronic circuits from harsh environments via a chemical film that “conforms” to a circuit board’s topography. These coatings protect against moisture, chemicals, contamination, vibration, corrosion, and thermal stress while improving product reliability by reducing failures. The benefits conformal coating can provide often vary in importance by industry. In aerospace electronics there is an emphasis on benefits of protection from corrosive gasses, outgassing, tin whiskers, and radiation. For the purpose of this article, we will focus on liquid coating materials.
