There is currently a growing interest in the area of drag reduction of unmanned aerial
vehicles. In this paper, the swarming flight of the fixed-wing drones and a load balancing …

Migrating birds may take advantage of V-shaped flocking to reduce the required energy for
their flight. Studies have shown that the birds in different positions in V-shaped flight contend …

We quantify the fuel and cost benefits of applying extended formation flight to commercial
airline operations. Central to this study is the development of a bi-level, mixed-integer real …

Flying airplanes in extended formations, with separation distances of tens of wingspans,
significantly improves safety while maintaining most of the fuel savings achieved in close …

This paper explores an analytic, geometric approach to finding optimal routes for
commercial formation flight. A weighted extension of the classical Fermat point problem is …

This article explores the three-dimensional flow structure of a streamwise-oriented vortex
incident on a finite aspect-ratio wing. The vertical positioning of the incident vortex relative to …

Numerous studies have confirmed that a significant improvement in fuel efficiency can be
obtained by flying aircraft in formation. From 2015-2018, Boeing conducted a study of …

In this paper, we study the leader-following formation tracking problem for multiple quadrotor
helicopters via the distributed observer approach. In contrast with existing results in the …

In this article, the formation mission design problem for commercial aircraft is studied. Given
the departure times and the departure and arrival locations of several commercial flights, the …

The continued development of sophisticated aircraft with high-fidelity control systems will
enable autonomous execution of challenging tasks such as aerial refueling and close …
