New formula for wing weight estimation, in conceptual design phase is derived for a tactical unmanned aerial vehicle (TUAV). Formula is derived by analyzing existing UAVs of the weighs from 100 to 500 kg, and which have similar characteristics. The materials suggested for UAV weight design are aluminum alloys and aluminum based composite materials. Software tools are developed in Matlab to facilitate takeoff and component weight calculations. The least square method is applied to analyze statistical data in order to develop trend functions which correlate TUAVs empty weight and takeoff weight. Existing formulas, developed for general aviation, for wing and takeoff weight estimations are applied to TUAV and promising one are selected and adjusted to TUAV conceptual design phase. Wing weight is related to geometrical parameters, maximum speed, and takeoff weight of the TUAVs. All existing and newly developed formulas are applied to typical TUAV example to validate it applicability.
