In order to investigate the steering performance of the ringsail parachute. the effect of two different steering approaches on the aerodynamic and gliding characteristics of a ringsail parachute is analyzed by using the numerical simulation and wind tunnel test. The first steering approach is to make ringsail parachute drift off course by changing the length of the suspension lines. w... https://countryscenesaddleryandpetsuppliers.shop/product-category/leather-wallet/
