Abstract

An air vehicle comprises a vehicle body and a propulsion assembly. The vehicle body has the shape of a wing airfoil so that the vehicle body generates lift when air flows over the vehicle body. The vehicle body has a body longitudinal axis, and includes a first hull and a second hull that are secured together side-by-side, the hulls having longitudinal axes that are substantially parallel to the body longitudinal axis. Each hull defines a separate fluid chamber that is filled with a fluid that is at least partially buoyant. The propulsion assembly is secured to the vehicle body. The propulsion assembly generates thrust and includes a port front engine, a port rear engine, a starboard front engine, and a starboard rear engine, wherein at least two of the engines have independently controlled thrust vectors.
