Description
Technical field
The technical field more particularly to a kind of screw pitch for adjustable pitch airscrew model precisely adjusted the present invention relates to screw pitch
Regulating device and its application method.
Background technique
Propeller, from the whether adjustable angle of the screw pitch of propeller, is divided into solid at present using most ship's propellers
Constant-pitch propeller (spacing paddle) and adjustable pitch propeller (tuning for Controllable Pitch Propeller), the latter are widely used in having multi-state operation function
Ship, generally by hydraulic device drive link slide block mechanism, to realize the tune of screw pitch during propeller operating
Section, to achieve the purpose that adapt to multi-state.
In the design phase of tuning for Controllable Pitch Propeller blade, generallys use and reduce the mode of model and detect hydrodynamic force under multiple angles of pitch
Performance, it is desirable that study subject and real scale propeller keep geometric similarity, therefore first have to production tuning for Controllable Pitch Propeller model.
The production of model is broadly divided into two classes: one kind is that the screw pitch that each needs are done experiment processes a propeller mould
Type only exists mismachining tolerance, does not adjust brought by screw pitch its advantage is that precision is high using integrally formed processing method
Error, intertrial interval only needs replacing subjects twice, test period is saved, the disadvantage is that production quantity is more, the period
Long, total cost height, is especially needing to detect the more situation of the corresponding screw pitch of hydrodynamic performance；Another kind of is production one each
The model propeller of blade Independent adjustable when needing to adjust screw pitch, for a certain blade, unclamps clamp device, by detecting paddle
The offset data of leaf surface feature locations judge pitch regulated situation, are fastened again after adjusting in place, prevent hydrodynamic force from surveying
Blade stress deflects when examination, and method makees same operation to other blades again according to this, its advantage is that only processing a propeller
Model, cost is relatively low, fabrication cycle is shorter, disadvantage first is that pitch regulated process brings adjusting error, the size of the error
It is generally bigger than the mismachining tolerance of overall processing dependent on the operation of roll adjustment personnel, disadvantage second is that adjust screw pitch process
It is time-consuming more, it could carry out after needing to wait subjects pitch regulated good during continuously carrying out model test subsequent
Work.In conclusion providing a kind of screw pitch essence that is quick, easy, being effectively used for the test of tuning for Controllable Pitch Propeller model hydrodynamic performance
Quasi- regulating device is need to solve the problems, such as.
