Four-bladed steerable propeller

cults3d

Here is a remix of the four-bladed swivel propeller for the Konchan77 turboprop (https://www.thingiverse.com/thing:3014536) that works. Indeed, its version with spur gears can't work; bevel gears must necessarily be used. This remix therefore uses bevel gears and a blade orientation control system integrated into the propeller cone. The nose of the cone is the control knob that can be rotated in either direction to achieve the correct blade pitch angle (from feathering to reverse thrust). The set consists of three parts: Rear block of the cone grouping : The blades and their bevel gears. The conical bush wheel and its thrust ball bearing. The back plate and its attachment to the PV output shaft of the turboprop. Central block containing the blade orientation mechanism consisting of : The bevel gear's double helical ramp sheath (emerging part of the rear block). The piston and its two guide bearings. Front block consisting of : The end cone which by its rotation will orient the blades. The lead screw. The assembly of the set will be done in this order: The blades. The rear block and possibly its attachment to the turboprop. The central block with the front block. We will come back to this in detail in the "Assembly" section. I would like to draw your attention to the precision of this assembly. The adjustment of many parts is 1/10mm. This requires for your printer a perfect calibration, perfectly controlled adjustments and the use of quality filaments. As for the realization of the konchan77 turboprop, this assembly is not for novices and requires rigour and precision.

The nose of the cone is the control knob that can be rotated in either direction to obtain the appropriate blade angle of incidence (from feathering to thrust reversal). The set is composed of three parts: Rear block of the grouping cone: The blades and their bevel gears. The tapered sleeve wheel and its ball bearing. The rear plate and its mounting on the turboprop PV output shaft. Central block containing the blade orientation mechanism consisting of: The double spiral ramp sleeve of the bevel gear (emerging part of the rear block). The piston and its two guide bearings.
