Abstract: An Unmanned Aerial Vehicle (UAV) has a fuselage, a rotor system, and a wing configured for selective positioning during flight of the UAV to a deployed position, a stowed position, and to positions between the deployed position and the stowed position. The UAV has a flexible wing skin at least partially carried by a leading arm and the leading arm is rotatable relative to the fuselage.

Abstract: A system and method to detect particles in a fluid stream. The system includes a separator configured to separate particles from bubbles passing through the fluid stream and a sensor configured to detect the particles. The method includes passing the fluid stream through the separator, separating the particles from bubbles passing through the fluid stream, and detecting the presence of the particles.
