Abstract
A turbine for a turbine engine is used for manufacturing the turbine engine. The turbine comprises a hub mechanism, a blade mechanism and a cooling mechanism. The hub mechanism is provided with a hub 1, a wheel shoulder 2 is arranged on one side of the hub 1, a cover plate 8 is arranged in the hub shoulder 2, shaft holes 4 are formed in the center of the hub 1 and the center of the cover plate 8, and locating grooves 5 are formed in the shaft holes 4. The blade mechanism is arranged between the hub 1 and the wheel shoulder 2. The cooling mechanism is arranged in the hub 1 and the blades 3. The root portions of the blades 3 are connected with the hub, one sides of the blades are further connected with one side of the wheel shoulder, and the work strength of the blades is improved. A hub cooling cavity is formed in the hub, a blade cooling cavity is formed in each blade, the work temperature and operating controllability of the blades can be controlled, and the economical efficiency of the turbine engine can be improved. The cover plate arranged in the wheel shoulder is connected with the wheel shoulder, and casting cost is lowered. The shaft hole locating groove formed in the center of the hub is connected with a turbine shaft, manufacturing and locating are facilitated, and the operation reliability of the turbine engine is also improved.
Description
Technical field
The present invention relates to use the turbogenerator manufacture of propellant agent, specifically a kind of turbogenerator turbine.
Background technique
The turbogenerator of manufacturing is at present burn in the pressurized air motor of work done of fuel, although specific power is higher, and its complex structure, manufacture cost is high, not only uses disposable fuel, and the face of going back is subject to oil crisis, and application area is limited.
Using turbosupercharger on the widest cylinder type engine is to utilize exhaust can promote the energy saving device that turbine in volute rotarily drives gas compressor work, and it is simple in structure, and specific power is higher.
Regenerative propellant agent LP-1846 constitutes: hydroxyl ammonium nitrate (oxygenant) weight accounts for 60.8%; Three ethanol ammonium nitrates (fuel), weight accounts for 19.2%; Water, weight accounts for 20% (the above two are cheap organic compounds); Feature is that density is large, toxicity is little, be difficult for lighting under normal pressure, Security is good; Also can, by biodegradation, to environment, can not pollute; Be uniformly mixed and can make, cost is low, the existing propellant powder for automatic gun.
Nb-Si based ultra-high temperature alloy has high-melting-point (more than 1750 ℃), low density, moderate Toughness, good hot strength and good corrosion resistance characteristic, can use in the temperature range of 1200～1450 ℃, for the preparation of high-temperature structural components such as Aero-Space, chemical industry, High Temperature Furnacess, be suitable for replacing platinum-rhodium alloy bushing, thereby significantly reduce the preparation cost of basalt fibre.
Summary of the invention
The present invention is directed to the problems referred to above, for manufacturing turbogenerator, provide a kind of turbogenerator turbine.
According to technological scheme of the present invention: a kind of turbogenerator turbine, comprises hub mechanism, blade mechanism, cooling mechanism.
Described hub mechanism is provided with wheel hub 1, and a side of wheel hub 1 is provided with wheel shoulder 2, is provided with cover plate 8 in wheel shoulder 2, and wheel hub 1, cover plate 8 centers are provided with axis hole 4, are provided with locating slot 5 on axis hole 4.
Described blade mechanism is arranged in wheel hub 1 and wheel shoulder 2, is provided with blade 3.
Described cooling mechanism is arranged in wheel hub 1 and blade 3, is provided with wheel hub cooling chamber 6, blade cooling chamber 7.
Technique effect of the present invention is: a kind of turbogenerator adopts Nb-Si based ultra-high temperature alloy material to make with turbine, and combustion agent initial temperature is high, and conversion efficiency is high; Adopt root of blade to be not only connected with wheel hub, blade one side is also connected with wheel shoulder one side, has increased the lifting surface area of blade, has improved the working strength of blade; Adopt to arrange in wheel hub blade cooling chamber is set in wheel hub cooling chamber, blade, not only can control the operating temperature of blade, save material, reduce cost, alleviated again motor weight, improved the controllability of running, also improved the Economy of turbogenerator; Adopt the cover plate arranging in wheel shoulder to be connected with wheel shoulder, not only reduced the casting difficulty of turbine, also reduced cost; The axis hole locating slot that adopts wheel hub center to arrange is connected with turbine shaft, and not only the convenient location of manufacturing, has also improved turbine and turbine shaft join strength, has improved the operation reliability of turbogenerator.
