Drones More Damaging to Aircraft than Birds

An FAA study concluded that drone collisions with aircraft cause more structural damage than birds of the same weight for given impact speed. Even small unmanned aircraft systems can do significant damage to engines.

NASA Data Aids California Wildfire Response

NASA’s Earth resources aircraft, as well as multiple satellites, are providing critical data to aid various agencies responding to the wildfires damaging vast areas of southern California. NASA operates two Lockheed ER-2 Earth resources aircraft as flying laboratories in the Sub-Orbital Science Program, collecting information on Earth resources, atmospheric chemistry and dynamics, and oceanic processes.

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.

Army Developing Lasers That Pierce Fog, Dust to Destroy Targets

A lot of people think that high-energy lasers, or HELs, can't penetrate fog, rain and dust, said Thomas Webber, director of the Directed Energy Division's Technical Center, U.S. Army Space and Missile Defense Command. That's just plain wrong.

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.

Designing With MIL-STD-1553B Components

The interconnected backbone of a MIL-STD-1553B vehicle depends on the electrical and mechanical reliability of the components, the design, and the installation. With the vast array of MIL-STD-1553B specified sub-assemblies, there are factors that can go overlooked for passive components such as couplers, cables, and connectors. Often built with kilometers of wiring, aircraft in particular can be difficult to troubleshoot and must be inspected frequently for potential failures such as intermittent connections, shorts, and corrosion. Still, these passive components that make up the network can be individually assessed to operate with a high level of integrity.
