Drone Collisions More Damaging Than Birdstrikes

Author: Maurits Rietveld, Editor Leonardo Times Birdstrikes have already been an important topic in aviation's safety for a long time. Considering the global rise of drones, collisions between drones and aircraft are starting to play a role in aviation safety as well. New studies have shed light on this issue. A study carried out by the Federal Aviation Administration (FAA) showed that small drones are more damaging to planes than birds. Simulations reinforced by physical material tests were done on aircrafts colliding with drones, varying in weight from 1.2 to 3.6 kilograms. The wing's leading edge, windshield and horizontal and vertical stabilizers were investigated as critical locations. Results showed that the horizontal stabilizer suffered most of the damage and the cockpit’s winds...

System Identification in Aerospace

Engineering relies heavily on mathematical models of real systems. However, physical processes are often highly complex and not entirely understood, so the modeling of the first principles can be challenging, sometimes even impossible. System identification allows for any system, however complex or obscure, to be modeled solely on the basis of measurements. System identification is the science of extracting a model from a set of observations or measurements. By looking at how a system behaves in specific situations, we can determine whether there are patterns in the behaviour and what factors influence it. The underlying idea is to formulate a basic model structure containing a number of unknown parameters, and then estimate these parameters such that the difference between measurements...
