- 2nd drawing: central part of the double-fins showing the different cut-outs, to fit all the three together. -
The Malot-rotor has a triangle-prism-axle.
It has three double-fins with a bend, which divides the two parts of the fins. This bend has an angle of 60 deg.
The double fins have out-cuts near the shaft to allow each of the three to be placed with the bend to cover one (different) edge of the shaft.
(The first and the third double-fin have the same shape, but they must be mounted in reverse direction to each-other, to get the out-cuts at the right place)
When the fins are assembled in the right way, the triangle-prism-axle can be put into the free central triangular space.
By inserting the triangle-shaft, the double-fins are fixed on the shaft in their position. There must be added a screw, to avoid sliding of the rotor-fins in direction of the prism-edges.
There is the possibility to make the double-fins collapsible, which can be the most interesting of that rotor-type.
If the 60deg- bends are replaced by articulations, with articulation-axle showing to the prism-edge, they can be collapsed when demounted.
In case of the collapsible fins, the triangle-prism-shaft must have cuts off on the edges, to bare the articulations of the double-fins. -These articulations are parallel to the edges (-in the place of the edges-) of the prism.
