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. WebFeb 1, 1986 · The DUST aerodynamic model of the full-scale XV-15 proprotor was built considering the airfoil geometry, chord, twist, sweep, and dihedral distributions reported in Reference [68].
