Abstract: An unmanned aerial vehicle (UAV) capable of vertical and horizontal flight modes, a method of assembling a UAV, and a kit of parts for assembling a UAV. The UAV comprises an elongated wing structure having an elongated axis along the longest dimension of the elongated wing structure, the elongated wing structure having a middle location at a substantially halfway point; a connecting structure extending substantially perpendicularly from the elongated wing structure, the connecting structure being offset from the middle location of the elongated wing structure at a first position along the elongated axis; and at least three sets of propellers, wherein at least two sets of propellers are mounted on the connecting structure, and wherein at least one set of propellers is mounted at a second position offset from the middle location in an opposite direction away from the connecting structure.

Abstract: A method and system for generating a set of values for respective ones of a set of parameters used in determining rotor blade profiles for a coaxial rotor system. The method includes establishing (302) a ratio of respective desired thrusts of an upper rotor (102, 602) and a lower rotor (104, 604) of the coaxial rotor system based on a desired performance of the coaxial rotor system, and determining (304) the set of values of the set of parameters from the desired thrusts ratio based on a torque balance condition between the upper rotor and the lower rotor of the coaxial rotor system.
