Empirical Evaluation of Ground, Ceiling, and Wall Effect for Small-Scale Rotorcraft
… using fixed propellers at variable speeds (e.g. multirotors). A parametric multirotor-specific ground effect model is developed and presented to overcome some of the limitations in classical helicopter theory.</p> <p>Likewise, ceiling effect refers to the apparent increase in lift that a …

Target Locating in Unknown Environments Using Distributed Autonomous Coordination of Aerial Vehicles
… reliability. A heterogeneous swarm of multirotors demonstrates the target locating problem, sharing information over a multicast wireless private network in a fully distributed manner to form an estimate of the signal's gradient, informing the direction of travel toward the target. The …
