Keywords: ucav unsteady aerodynamics, maneuver loads, unsteady flow control

The unsteady aerodynamics (loads and moments) of a UCAV 1303 configuration is discussed for the first time. Major differences were observed from steady flow. Dynamic lift, alleviation of tip-stall and changes in vortex onset mechanisms are determined to be the reasons for these.
