The invention discloses a design method of a high-efficient thruster with coaxial and reverse dual propellers. The design method comprises the steps: firstly, establishing whole flow velocity, flow rate and energy math equations according to principles that motion laws of air stream in the front and rear propellers are respectively independent and inter-related in the aerofoil theory; secondly, determining an inflow angle, an outflow angle and a mounting angle of each aerofoil of dual propellers according to the above math equations; thirdly, calculating total energy and axial energy, determining internal diameters, external diameters and specific values of two propellers; finally, designing and manufacturing a propeller model according to the above parameters, and performing experimental verification and parameter amendment; the coaxial and reverse dual propellers manufactured by utilizing the design method are capable of remarkably promoting thrusting ability and power-energy conversion efficiency.
