An unmanned aerial vehicle (UAV) having a toroidal fuselage and a rotor assembly including counter-rotating rotors coaxially mounted with respect to the toroidal fuselage incorporates ancillary aerodynamic structures aerodynamically configured and mounted in combination with the toroidal fuselage to provide a nose-down pitching moment to counteract the nose-up pitching moment generated by airflow over the toroidal fuselage during forward translational flight of the UAV. The ancillary aerodynamic structures have a cambered airfoil profile to provide high ...
An unmanned aerial vehicle, comprising: a toroidal fuselage having a coaxial fuselage axis and a longitudinal axis, said toroidal fuselage being fabricated as a closed toroid that is a partially hollow structure that provides a plurality of accessible internal bays and wherein said toroidal fuselage is symmetric with respect to said coaxial fuselage axis and said longitudinal axis, said symmetrical toroidal fuselage defining an inner flow duct, airflow over said symmetrical toroidal fuselage and through said inner flow duct during forward translational f...
