Abstract
The invention discloses lubricant composition for an open rotor engine. The lubricant composition adopts trimethylolpropane ester as the base oil and is matched with multiple additives including an antioxidant, an antirust agent, an oiliness agent, a friction modifier, a metal deactivator, an anti-fatigue agent, an anti-oxygen preservative, a bearing agent and an anti-foaming agent. The lubricant composition has good low-temperature fluidity, lubricity, wearing resistance, load resistance, corrosion resistance, heat resistance and oxidation stability, reduces wear of bearings and gears, controls little carbon deposition and has high dispersing and cleaning capacity.
Description
Technical field
The invention belongs to engine lubricant field, particularly open rotor engine lubricant compositions.
Background technology
Open rotor engine adopts a pair fan mutually reversed, and can be designed as extending type or push type.Its most distinguishing feature to obtain high bypass ratio, estimates to reach as high as more than 30.Owing to removing engine nacelle, reduce resistance, estimate that the open rotor engine of reversion mutually can save the fuel oil consumption of 10%.But it is Shortcomings also: the fan diameter of engine is almost 2 times of duct nacelle width, adds the weight of engine; Its noise is comparatively large, the important cause of noise: whether the thickness of blade, blade tip rotating speed be faster etc. than the velocity of sound.Open rotor engine is with higher puopulsion efficiency, and lower oil consumption and Carbon emission, become the Typical Representative of economic friendly engine, have very strong competitive edge.Say from structure, it is the propfan engine of a kind of performance between turbo oar engine and fanjet, and its unit weight thrust oil consumption is between fanjet and turbo oar engine.
Its structure and characteristics: its core engine is still the gasifier of anti-high gas turbine engine.The quality of core engine performance directly determines the performance of propfan engine.Structural typical feature is that it adopts minor diameter many blades open type fan to make propeller.Propeller blade is different from the blade of whirlpool oar, and common blade required thickness is greatly to ensure sufficient intensity, and blade profile camber is greatly to ensure enough lift coefficients.Oar fan propeller blade adopts overcritical blade profile, and blade profile is thinning, wounds ability to improve anti-foreign object.Under same tip speed, rotating speed is higher, reduces the reduction ratio of wheel casing, reduces the weight of propfan engine.
Say from technical standpoint, its difficulty manufactured and designed is comparatively large, and propeller blade works in outflow at a high speed, pneumatic design difficulty, easily with wing, the engine nacelle of aircraft, causes together and mutually disturbs and resistance is increased.In addition, the advanced material that propeller blade adopts and processing and manufacturing, also have design bearing, and the difficulty such as lubrication and reduction noise are all larger.Propfan engine is one of promising engine of most in extraordinary aircraft engine as a kind of novel aviation power equipment.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind ofly has good low-temperature fluidity, oilness, resistance to abrasion, load resistance, erosion resistance, thermotolerance and oxidation stability; Reduce bearing and gear wear, control carbon deposit few, the open rotor engine lubricant compositions that dispersion cleansing power is strong.
