Unmanned aerial vehicle systems and methods of use

An improved unmanned vehicular system for airborne deployment, which comprises:

• (a) a vehicle fuselage having a top aspect, a lower aspect, and a center of mass, wherein said vehicle fuselage is aerodynamic in shape, having an elongate and generally tubular vehicle body assembly with a center Z-axis, such that said center of mass is partitioned to a lower half of said Z-axis thereof;
• (b) a dual rotor head having an apical aspect and an inferior aspect, said rotor head comprising an apical rotor assembly and an inferior rotor assembly, wherein said two rotor assemblies are stacked with a common center axis of rotation;
• (c) each rotor assembly having unfoldable fixed-pitch rotary blades or wings configured to generate lift, and comprising each an electrical motor operatively mounted thereto, wherein said each motor is driven from a power source and separately controllable by a motor speed controller, and wherein said two rotor assemblies are configured to rotate as counter rotational rotor assemblies that generate opposing torque;
• and
• (d) in combination with said dual rotor head and fixed-pitch rotary blade assemblies, a power gimbal having a gimballed neck that couples said inferior aspect of said rotor head to said top aspect of said fuselage, said gimballed neck comprising powered gimbal bias elements actuated by a gimbal controller enabled to articulate the pitch attitude of said rotor head relative to said fuselage under control of an on-board navigational, communication and steering system;
• (e) further characterized in that said steering system comprises said motor speed controller and said gimbal controller under control of a processor operatively connected thereto, wherein said motor speed controller and said gimbal controller are controllable to achieve yaw control, precession control, and coordinated steering control without a cyclical pitch control means on said rotary blade assemblies.
