Extension, Validation and Application of the DA VII Transonic Airfoil Code with Passive Shock Controlayer interaction with grid adaptation. The numerical results are in agreement with the experimental data concerning the wave drag reduction but also the viscous drag increase. In addition, the SC code has been applied for a parametric study of the main passive SC design parameters to support the design of the DA LVA-1A model for passive SC.作者: 防御 時(shí)間: 2025-3-25 23:07

Airfoil Tests with and without Control (Task 3), in addition, have smaller margins as far as drag-rise and buffet boundaries are concerned when compared to turbulent designs. During the course of the investigation, having perused early results, it was agreed that DLR would retest the original airfoil VA-2 which had demonstrated the benefits of passive control [1.3].作者: 阻撓 時(shí)間: 2025-3-26 06:26 作者: meditation 時(shí)間: 2025-3-26 09:13
