Journal of the institution of engineers (India): Series CSummary: A buoyant shrouded airborne wind energy system (BUS-AWES) is an important concept in the field of the wind power industry. Despite this importance, created designs in this area have defects and are not optimized. In other words, aerodynamics, aerostatics, and performance issues of the wind turbines are not considered balanced in the existing schemes. This paper presents a new and comprehensive preliminary approach to overcoming this problem. Both aspects of flight performance and wind power production performance are met in the sizing and configuration design. In the proposed method, the lighter-than-air carrier is designed based on a torus-like volume whose cross-section forms an airfoil so that its envelope has the proper aerodynamic shape of an aircraft. Its convergent/divergent internal duct is formed to locate the wind turbine (rotor). Experiences in the field of aerostat design have been used in body sizing and airfoil selection to create a suitable volume of the hull for the production of buoyancy force and also to produce effective aerodynamic forces. This improvement of the aerostatic and aerodynamic conditions of the aircraft will improve flight performance, especially the reduction of the blowdown angle of the aircraft. The convergent/divergent duct, created in the hull in which the rotor is installed at its throat, has caused the flow velocity inside the duct to exceed the free flow velocity and the wind power density per unit area (watts per square meter) will increase significantly.

A buoyant shrouded airborne wind energy system (BUS-AWES) is an important concept in the field of the wind power industry. Despite this importance, created designs in this area have defects and are not optimized. In other words, aerodynamics, aerostatics, and performance issues of the wind turbines are not considered balanced in the existing schemes. This paper presents a new and comprehensive preliminary approach to overcoming this problem. Both aspects of flight performance and wind power production performance are met in the sizing and configuration design. In the proposed method, the lighter-than-air carrier is designed based on a torus-like volume whose cross-section forms an airfoil so that its envelope has the proper aerodynamic shape of an aircraft.
