Web7 apr. 2024 · 3.3 Introducing the Induction Factors on the Blade. Since the lifting-line assumption is used in the BET, it is possible to define the velocity triangle in terms of the axial and tangential inductions factors \(a_B\) and \(a'_B\) (see Sect. 4.4). The axial induction factor is appropriate when \(U_0\ne 0\).
