MethodologyThe authors of this paper have modeled and 3D printed three different custom constructedshrouds with inlet angle 20,25,30.Figure 1 shows the modeled 30-degree shroud design.Figure 1 – Designed and 3D Modelled 30 degree shroudThe shroud with 30-degree angle was selected as it delivers significantly improved performanceand power efficiency when compared to other shrouded wind augmentation devices withdifferent anglesand a large wind augmentation device was manufactured using galvanized steelas shown in Figure 2. We initially designed different prototypes with different dimensions andanalyzed the turbulence flow of the air and finalized the prototype with maximum turbulenceoutput as shown in figure 3. In considerations with our budget limitation, we have scaled theprototype to the maximum dimensions possible. The device measures 60 inches in length, 50inches outlet diameter and 72 inches inlet diameter as shown in figure 4.

Figure 4– Schematic Figure of the deviceWhile considering the shape and size of the inlet cone the authors followed the aerodynamicdesign of the of the nose cone section of rocket and missile to get the best optimal performance.The authors have chosen to adapt the conical nose cone shape design considering their optimalperformance output and ease of construction.Source: NASA
