Winds of Change – A Proposal to Reconstruct Wind Flows for Urban Air Mobility

The Wind Beneath – Above, In Front of, and Behind – Your Wings. (Or Perhaps Your Rotors).

Predicting wind flows for UAM is a challenge to the safe integration of uncrewed aircraft systems into the national airspace. One researcher proposes a solution using a computational fluid dynamics (CFD), Reynolds-average Navier Stokes (RANS) model with current real-world observation.

A Drone Militaries Can Use to Seek and Destroy or Seek and Return

To Loiter or Not to Loiter, That Is the Munitions Question of the Day

Costa Mesa, California-based Anduril Industries has literally and figuratively launched its boomerang drone bomb. Equipped with an autonomous, artificial intelligence (AI) “brain,” the Roadrunner UAV is capable of taking down a moving target midair and destroying itself on impact. Should the mission not achieve its objective, Roadrunner will turn itself around and land itself nose-up…
