TLDR
The control parameter Kf in Eq. (9) was adjusted for the 60-deg delta wing to achieve onset of vortex burst at the wing trailing edge at a = 13 deg as mentioned in this paper.Abstract:
The control parameter Kf in Eq. (9) is the only variable needed to fine-tune the vortex-burst predictions. It was adjusted for the 60-deg delta wing to achieve onset of vortex burst at the wing trailing edge at a = 13 deg. A value of 2.6 for Kf gave this result. When this same value of Kf was used for VBM/VLM computations over a range of angles of attack for each of the wing shapes tested, the vortex burst locations shown in Fig. 1 resulted. Wind-tunnel values for burst locations on similar models from Refs. 8 and 9 are plotted in Fig. 2 for comparison. Note the good agreement between the model and wind-tunnel data for all shapes tested.read more
