Abstract

The invention discloses carrier-based aircraft tractor hydraulic oil. The carrier-based aircraft tractor hydraulic oil is characterized in that a dioctyl sebacate compound prepared from polyalphaolefin and castor oil is used as base oil; dioctyl sebacate is compounded with a plurality of composite additives comprising an anti-oxidant, an antiwear agent, a friction improver, a metal passivator, an antirust agent, an anti-foaming agent, a demulsification agent and an anticorrosion assistant. The carrier-based aircraft tractor hydraulic oil has excellent antioxidation stability, wear resistance and rust resistance, can resist sea severe condition influences, can protect a hydraulic member, can ensure power transmission accuracy, can realizes displacement in a predetermined path, has outstanding air release properties, emulsification resistance and foam resistance, has stable composition, does not corrode equipment, has no toxicity and an excitant smell, and is suitable for a carrier-based aircraft tractor hydraulic system.

Description

technical field [0001] The invention belongs to the field of hydraulic oil for shipboard aircraft tractors. Background technique [0002] On modern aircraft carriers, apart from the runway, there are very few places where aircraft engines can run. The movement of carrier-based aircraft before takeoff and after landing, as well as entering and exiting elevators, must be pulled or pushed by tractors. The carrier-based aircraft tractor is the carrier-based aviation support vehicle with the largest number of equipment, the most frequent use, and the earliest flight deck. After the deck and hangar of an aircraft carrier are fully loaded with carrier-based aircraft, the aisles that can be dispatched by tractors and towed aircraft are very narrow. Therefore, the shape of the tractor is very compact, especially the height of the vehicle body should be low enough to safely drive under the wing or even the fuselage of the carrier-based aircraft; in addition, the turning radius should...
