Force divergence mach number
WebR// The Mach number which produces a sharp change in the drag coefficient is termed the “force divergence.” Is the Mach number where drag waves start to form. R // The Mach number which produces a sharp change in the drag coefficient is termed the “ force divergence . ” Is the Mach number where drag waves start to form . 7. Web(A) The critical mach number increases significantly. What is the result of a shock-induced separation of airflow occurring symmetrically near the wing root of a sweptwing aircraft. (B) A severe moment or "mach tuck" What is the main disadvantage to the swept wing design? The wing tip section stalls before the wing root.
