A new high altitude propeller is analyzed and designed in this paper to be used on the stratospheric aircraft propulsion system. Two more appropriate approaches to investigate the aerodynamics characteristics of the high altitude propeller are obtained by comparison of vortex theory with the Spalart-Allmaras (S-A) model and XFOIL program. computational fluid dynamics (CFD). and wind t... https://spencertifieders.shop/product-category/video-cards/
