WebApr 17, 2024 · Aerodynamic atomization will produce an ultrafine fog curtain and a high-speed wind curtain, fog droplets in the fog curtain will capture the free dust, and the turbulent air layer formed by the wind curtain will restrain the dust diffusion (Wang et al. 2024; Liu et al. 2024; Cai et al. 2024). Therefore, the accuracy of the simulation is ... Webexert the first aerodynamic forces on the entry ve- hicle. Knudsen number, Kn, is defined as the ratio of the quiescent gas’s mean free path to the vehicle’s diameter. At the outer reaches of the atmosphere, Iin is large. As long as Kn > 10, the associated aerodynamic forces can be accurately computed by a free-molecular-flow method.
WebRotorcraft brownout is caused by the entrainment of dust and sand particles in helicopter downwash, resulting in reduced pilot visibility during low, slow flight and landing. Recently, brownout has become a high-priority problem for military operations because of the risk to both pilot and equipment. Mitigation of this problem has focused on flight controls and … May 21, 2015 ·
