An aircraft for vertical take-off and landing includes an aircraft assembly which includes at
least one first wing portion providing a lift force during a horizontal flight, at least one wing …

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 …

An aircraft for vertical take-off and landing includes an aircraft frame having an open frame
portion, at least one vertical thruster, a pod, separable from the aircraft and including a cabin …

A flapping flight mechanism of the Canada goose (Branta canadensis) was estimated using
a two-jointed arm model in unsteady aerodynamic performance to examine how much …

Several bird species have been observed to fly in V-formation, an arrangement which
exploits aerodynamic features to allow the group to conserve energy when migrating over …

This paper investigates aerodynamic performance improvements of formation flight at
transonic speeds for a medium size Unmanned Aerial Vehicle (UAV). The metric for …

Although the spontaneous collective behavior of swimmers has attracted considerable
attention, there has been little physical discussion of the extensibility of the collective system …
