The bottom of the oil tank 1 is provided with a groove. The upper end face of the oil tank 1 is a plane, and an oil tank fixing bracket 1.1 for connecting an aircraft is arranged on the periphery of the oil tank 1. The oil tank 1 of the invention adopts high-density epoxy resin material, thus effectively preventing the permeation and corrosion of gasoline. The shape adopts the hemisphere, is more favorable to fuel and the oil hammer to rock along with the aircraft gesture slope and change the position, and the hemisphere can increase the space utilization, reaches the volume maximize in the oil tank of same weight level. The oil tank oil inlet is arranged on the upper surface, so that fuel can be prevented from being splashed out when the aircraft shakes, and meanwhile, the convenient and fast oiling function is improved. The bottom of the oil tank is in a groove shape, so that dead oil quantity is reduced to the greatest extent.
As in fig. 1 (b): the oil pipe (the oil supply pipe and the oil return pipe) adopts the rubber hose, when the airplane tilts and shakes, the oil pipe can ensure that the oil hammer slides back and forth without external force, and because the liquid can receive the gravity factor and change the position along with the change of the tilting posture of the airplane, the oil hammer also slides along with the change of the tilting posture of the airplane, so that the oil hammer can be always contacted with the liquid. As shown in the figure, two hoses are provided, one hose is an engine oil supply pipe, and the other hose is an engine oil return pipe. The hose is made of epoxy resin material, so that the hose is oil-resistant and corrosion-resistant.
