The invention relates to an integral bearing type conformal fuel tank and system for an unmanned helicopter, belongs to the technical field of unmanned aerial vehicles, and can solve the problems that a large-capacity fuel tank is difficult to arrange in a compact unmanned helicopter and the influence of fuel quantity change on the gravity center of the whole helicopter is large. The conformal fuel tank comprises a first U-shaped part, a second U-shaped part and a third U-shaped part, the first U-shaped part is vertically arranged, and an opening of the first U-shaped part faces upwards; the second U-shaped part and the third U-shaped part are horizontally arranged, openings of the second U-shaped part and the third U-shaped part are opposite, and the second U-shaped part and the third U-shaped part are located above the first U-shaped part; one opening ends of the three U-shaped parts are connected with one another, and the other opening ends of the three U-shaped parts are connected with one another; the three U-shaped parts are of hollow structures and are connected with one another to form fuel oil cavities which are communicated with one another and are used for containing fuel oil for a machine; the conformal fuel tank is respectively connected with the fuselage front section and the fuselage rear section to form a fuselage which is coherent in appearance and can transmit flight loads.
