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.

Sensors Detect Aircraft Damage as it Occurs

The Army developed and tested networked acoustic emission sensors that can detect airframe damage on conceptual composite UH-60 Black Hawk rotorcraft. The sensing method can be used to reliably detect and locate the initiation and growth of damage that may occur during service.

A Better Understanding of Space — Via Helicopter

An algorithm that helps engineers design better helicopters may help astronomers more precisely envision the formation of planets and galaxies. The new model understands how black holes, planets, and galaxies emerge from the vortex-rich environments of space. Researchers drew inspiration from a mechanical engineering algorithm that shows how air flows past a helicopter’s rotor blades.
