trim drag trim dragOperation of trim tab may change the value of lift and drag values. Any additional drag by operation of trim tabs is called trim drag.An increment in drag, resulting from the aerodynamic trimming of an aircraft. The tailplane in any aircraft produces lift, which may be positive or negative. In the process of producing lift, drag is also produced. If additional lift is required to trim longitudinal forces, then the drag produced is called trim drag. Its value is maximum when the aircraft is flying at low transonic speeds. |
