Description
Technical field
A kind of translation class screw propeller, belongs to technical field of aerospace, particularly relates to a kind of translation class screw propeller.
Background technology
Traditional aircraft screw propeller plane of rotation can only produce pulling force or thrust when laterally vertically arranging, can not produce lift; Blade is curved surface, and the curvature at different radii place and section are not identical, and processing and manufacturing difficulty is large.
Summary of the invention
The object of the invention is the above-mentioned deficiency overcoming existing aircraft screw propeller, invent the translation class screw propeller that a kind of blade construction simply can produce lift and thrust or pulling force simultaneously.
A kind of translation class screw propeller, the rotating vane that the structure that to comprise main shaft, sun gear different with the setting angle of two, three of being evenly distributed on around sun gear or four only blade is identical.Main shaft vertical equity is arranged, the stage casing of main shaft is connected in the centre hole of sun gear by bearing and sun gear, and main shaft can flexible rotating in the centre hole of sun gear.Sun gear is fixedly mounted on support.The front end of main shaft is connected with power.Each rotating vane comprises arm axle, rachis, blade, nearly heart gear, arm axle sleeve pipe, heart gear far away and leaf-teeth wheel.The plane configuration of blade is rectangular, and blade inlet edge is more abundant, and trailing edge is thinner, and blade is nonrigid, has elasticity.The aerofoil profile of blade is flat pattern under the recessed or epirelief of epirelief, and different length positions aerofoil profile is identical.
The interrelation of the component in same rotating vane is: the rachis front end that be fixed on rachis vertical with arm axle, and rachis vertical equity is arranged, rachis and arm axle and main shaft are in same plane.The rear end of rachis is taken turns by bearing and leaf-teeth and is connected in centre hole that leaf-teeth take turns, and leaf-teeth wheel can around rachis flexible rotating.Leaf-teeth wheel and blade are fixed on the center place of the leading edge of blade.During quiescence, rachis and blade are in same level.Arm axle sleeve pipe is contained in around arm axle stage casing by bearing carrier ring, arm axle can in arm axle sleeve pipe flexible rotating.Nearly heart gear and heart gear far away are fixed on the two ends of arm axle sleeve pipe respectively.Heart gear far away and leaf gears meshing, its transmitting ratio is 1: 1.
The rear end of main shaft is vertical with the arm axle of all rotating vanes to be connected.The nearly heart gear of all rotating vanes all engages with sun gear, and the transmitting ratio of sun gear and all nearly heart gears is all 1: 1.Sun gear and all nearly heart gears, heart gear far away and leaf-teeth wheel all adopt finishing bevel gear cuter.When assembling this translation class screw propeller, guarantee that vaned reference position is level attitude, and the convex surface of blade upward, like this, because sun gear maintains static, and the transmitting ratio that sun gear and all leaf-teeth are taken turns is 1: 1, the blade that arbitrary leaf is walked around to this rotating vane during any position all can be in horizontality.
The principle of work of this translation class screw propeller is: arranged by the main shaft vertical equity of this translation class screw propeller, upward, forward, the front end of main shaft, is connected power backwards to the leading edge of blade to the convex surface of blade by trailing edge, and the frame of support and propulsion source is connected.See from back to front, power driven main shaft clickwise, because sun gear is fixing, and the transmitting ratio that sun gear and leaf-teeth are taken turns is 1: 1, blade can conter clockwise rotation under the drive taken turns at corresponding leaf-teeth while main shaft revolution, on the right side of longitudinal vertical guide crossing main shaft, clap under blade, its leading edge keeps horizontality, and the displacement of clapping under length direction and the identical chord positions of cross blade is identical, realizes flat bat downwards; In the left side of longitudinal vertical guide of mistake main shaft, blade arsis, its leading edge also keeps horizontality, and the displacement along length direction and cross blade identical chord positions arsis is also identical, realizes upwards flat bat.Main shaft rotates continuously under the driving of power, each blade alternate carries out lower bat and arsis, because blade is nonrigid, there is certain elasticity, in the midway of lower bat, the trailing edge of blade want delayed leading edge some, arsis midway trailing edge also can delayed leading edge some, because the aerofoil profile of blade is flat pattern under epirelief concave shape or epirelief, their lower bats can produce larger lift upwards and less thrust forward; Compared with lower bat, during arsis, the degree of their the delayed leading edge of trailing edge is larger, larger thrust forward and less lift upwards can be produced during arsis or do not produce lift, the size producing lift is relevant with the speed that such screw propeller moves ahead, and front line speed is faster, and the lift of generation is larger.Blade substantially laterally can not produce horizontal component of force in the process of flapping motion, and the efficiency producing lift and thrust is higher.
The blade of equal section easily makes.This invention class screw propeller is used on aircraft in pairs, can be aircraft and provide lift and thrust in the middle part of the trailing edge that symmetry is arranged on the left and right wing of aircraft.Power inputs from the front end of their main shaft, and their support should be fixedly mounted on wing.Two class propeller turning directions are contrary, can offset rotating torque.
