Summary of the invention: the present invention adopts the mode of step helix blade to make the rotor blade of the rotor blade gas turbine of steam turbine, the low pressure fan high-pressure fan high and low pressure turbine fan of airplane engine, the blade of making is not in one plane, but step helix blade, thread type spirals several weeks around wheel hub, blade equates with spacing between the blade, ladder distance between blade and the blade equates, the blade lean angle is consistent, the flight pitch of spiral equates, the size of blade designs by practical use, can make in the same size and also can make ascending, descending blade.It is consistent that the high pressure cylinder rotor blade of steam turbine is made specification, and step helix several weeks equidistant waits the pitch of thread rotors such as ladder distance.The middle air cylinder rotor of steam turbine is made the blade that causes diversified in specifications, and step helix several weeks equidistant waits the pitches of thread such as ladder distance, and blade is successively by the little gradually rotor of amplification.The low-pressure cylinder rotor of steam turbine is made the blade that causes diversified in specifications, and step helix equidistantly waits the ladder distance several weeks, and is unequal around the flight pitch of wheel hub, and blade is successively by the little rotor that significantly amplifies gradually.It is consistent that the cylinder rotary high-pressure fan blade of gas turbine is made specification, be assembled on the rotor hub step helix several weeks, blade and blade equidistantly wait the angles of inclination such as the pitch of thread such as ladder distance, the power output rotor turbine blade of gas turbine is made the blade that causes diversified in specifications, be assembled into step helix several weeks equidistant wait ladder apart from etc. the angle of inclination turbine, flight pitch around wheel hub is unequal, and blade is successively by the little rotor turbine blade that significantly amplifies gradually.It is consistent that the low pressure fan of airplane engine is made the blade specification, one week of step helix is many, blade is consistent with the spacing of blade, blade is consistent with the ladder spacing of blade, the angle of inclination of blade is consistent, blade rotates sub-one week of wheel hub, prevent vibration with this mode regulation moving balance, the high-pressure fan of airplane engine makes that blade is diversified in specifications to be caused, and step helix rotates sub-wheel hub several weeks, and blade is consistent with the spacing of blade, blade is consistent with the ladder spacing of blade, the blade wheel hub flight pitch that spirals that rotates is consistent, and the blade specification is shortened gradually by long, and the rotor high-pressure fan of making is the circular cone cylindricality.The high and low pressure turbine fan blade of airplane engine is made diversified in specifications causing, the blade specification is lengthened gradually by short, step helix rotates sub-wheel hub several weeks, blade is consistent with the spacing of blade, the angle of inclination of blade is consistent, and blade is consistent with the ladder spacing of blade, and the blade wheel hub flight pitch that spirals that rotates is consistent, also can make pitch inconsistent, make the turbine fan blade that strengthens step by step the flight pitch that spirals.The step helix impeller assembly dispenses the working efficiency that the nozzle static cascade can improve steam turbine gas turbine airplane engine, below in conjunction with accompanying drawing structure of the present invention is further described, accompanying drawing 1 is turbine high-pressure cylinder sectional drawing, mark 1 is the high pressure cylinder shell in the accompanying drawing 1, the 2nd, rotor blade, the 3rd, rotor hub, the 4th, rotor shaft.
Description of drawings: accompanying drawing is turbine high-pressure cylinder sectional drawing, mark 1 is turbine high-pressure cylinder baffle body among accompanying drawing 1 figure, this frame is the same with conventional turbine high-pressure cylinder baffle body function, and just structure is different, inside does not need inter-stage nozzle leaf grating, the 2nd, turbine high-pressure cylinder rotor blade, blade equates with the spacing of blade, the angle of inclination of blade is consistent, blade equates with interlobate ladder spacing, rotate sub-wheel hub step helix of blade is arranged and is become shape of threads several weeks, screw thread equates with flight pitch, the 3rd, and turbine rotor wheel hub, the 4th, turbine high-pressure cylinder rotor shaft.
Embodiment: adopt the manufacturing process of conventional manufacturing steam turbine gas turbine airplane engine high pressure cylinder intermediate cylinder low pressure cylinder, adopt conventional material to make steam turbine step helix blade.Turbine high-pressure cylinder rotor is made the step helix blade, rotor shaft like conventional, rotor hub is made an Integral hub and is convenient at wheel hub the step helix blade is installed, high pressure cylinder rotor blade specification is consistent, blades installation is on wheel hub, blade equates with the spacing of blade, the angle of inclination is consistent, the ladder spacing is consistent, around wheel hub spiral several weeks, the flight pitch of spiral equates, does not establish the nozzle static cascade between the screw thread of spiral, blade is top not to be established the border and connects FE Tiler, and high pressure cylinder housing and rotor blade be top less gap.Steam turbine intermediate cylinder low pressure cylinder rotor is made the step helix blade, rotor shaft like conventional, rotor hub is made an Integral hub, presses low pressure rotor step helix blade in wheel hub is installed, in force down the diversified in specifications of rotor blade and cause, descendingly install successively, blade equates with the spacing of blade, and the angle of inclination of blade is consistent, blade equates with the ladder spacing of blade, and blade equates also can make unequal screw spacing around the flight pitch of wheel hub spiral.Gas turbine step helix blade is made the consistent blade of specification, is installed on the rotor hub of high pressure cylinder.Fan blade equates with the spacing of blade, the angle of inclination of blade is consistent, blade equates with the ladder spacing of blade, blade equates around the screw spacing of wheel hub spiral several weeks, the power output rotor turbine step helix blade of gas turbine, make the blade that causes diversified in specifications, be assembled into step helix vane rotor turbine, blades installation is on rotor hub, blade is successively by the little blade that amplifies step by step, blade equates with the spacing of blade, and the rotate flight pitch of sub-wheel hub spiral of blade is unequal, by the little flight pitch that amplifies step by step.Airplane engine step helix blade, the low pressure fan of mode of execution is made the consistent blade of specification, blade assembling is on wheel hub, blade equates with the spacing of blade, the angle of inclination of blade is consistent, blade equates with the ladder spacing of blade, and one week of spiral winding wheel hub has a surplus, and adopts the method for increase and decrease blade to adjust the low pressure fan degree of balance.Prevent vibration, the high-pressure fan blade of airplane engine is made consistent specification, the step helix formula is installed on the wheel hub of high-pressure fan, blade equates with the spacing of blade, the angle of inclination of blade is consistent, blade equates with the ladder spacing of blade, blade equates around the screw spacing of high-pressure fan wheel hub spiral several weeks, the high-pressure fan of airplane engine can make also that blade is diversified in specifications to be caused, blade assembling is inconsistent around the pitch of wheel hub spiral, but blade equates with the ladder spacing of blade, and each Zhou Youda of blade screw dwindles gradually and arranges the high-pressure fan of making and become the circular cone cylindricality.The high and low pressure turbine fan blade of airplane engine is made diversified in specifications causing, the blade specification is lengthened gradually by short, be assembled on the rotor hub, blade equates with the spacing of blade, the angle of inclination of blade is consistent, blade equates with the ladder spacing of blade, and blade equates around the pitch of wheel hub spiral, also can make the unequal turbine fan blade of helical pitch.
