Abstract: A composite aircraft wing that includes a core, a first composite material disposed over the upper surface of the core, and a second composite material over the lower surface of the core. The second composite material is a different composite material than the first composite material. In addition, a first wood veneer layer is disposed over the first composite material and a second wood veneer layer disposed over the second composite material. The wing is lightweight, has an airfoil shape, and is easy to construct without using molds, while also being strong enough to support the weight of the aircraft. When used on a UAV-type aircraft having a wing-mounted antenna, the wing construction has little or no RF impact on the antenna.

Abstract: Pitot probes are described that are designed to prevent water blockage of the probe's air pressure orifice. The pitot probes are small, inexpensive, light weight and do not require power for heat generation. This makes the pitot probes particularly useful for use on UAV's and other small aircraft where size, cost, weight and power constraints are a major concern. The pitot probes utilize passive methods in the form of geometrical and material configurations to prevent blockage of the pitot probes by water droplets. The probes can also include water reservoirs that store collected water.

Abstract: An unmanned aerial vehicle (UAV) is designed for low-speed, low altitude, long endurance missions typical to UAVs of this size and class. The UAV structure is configured to be substantially impervious to small arms fire and to have a very small representative radar cross-section. The UAV is modular such that the main wings and tail wing assembly are quickly and easily, detached from the fuselage for ease of transport and to provide an airframe that is quickly and easily adapted to any particular mission.
