Page 10: Assembly Instruction Of The Propeller
5. Assembly instruction of the propeller The assembly of the SWIRL-2 propellers is shown below. It is recommended to assemble the propeller on a worktable before installing it on the plane. The procedure is the same for two-blade and three-blade SWIRL-2 propellers. -
Page 11: Installation On The Aircraft
If needed, see in annex 11.1. Dimension of the engine propeller-shaft. Remark: All engines having a propeller-shaft with a P.C.D. Ø101.6mm/Ø4" can install the SWIRL-2 propeller directly. The holes of the metal inserts of the rear half-hub must be adapted to suit with the indexing paws of the propeller-shaft. - Page 12 A spacer is necessary in the following case: Engine propeller-shaft type Jabiru (6 indexing paws Ø14mm on P.C.D. Ø101.6mm/Ø4") Engine propeller-shaft placed inside the engine hood or not place at more than 14mm Determination of the spacer length: Measure the distance X between the propeller-shaft and the engine hood limit, then add 14mm.
- Page 13 45 N.m information. Remark: It is imperative to use a spinner when using propeller SWIRL-2. The mounting plate of the spinner can be placed before or after the spacer adaptation. It is necessary to adapt the mounting in function of its position.

5.3. Setting of the propeller & Finalization of the installation At this point, the propeller is installed on your aircraft with the spinner mounting plate. If the propeller is already assembled and the blades angle set, pass directly Otherwise, follow all the steps below to adjust the pitch angle before the final tightening of the screw. - Page 15 SWIRL-2 Slightly untighten the propeller fixing screws and the hub assembly screw. Note : M6 screw presence in the case of the Compact Hub version. Adjustment roller of the leading edge 25 cm Reading blade angle Intrados of the blade with the...
- Page 16 After a final verification (position and orientation of parts, tightening...), mount the spinner on the mounting plate by tightening the spinner screws to a torque of 4Nm (0.4kg/m) with the appropriate tools. In the presence of a marking, please respect the indexing of the spinner from its plate. SWIRL-2 At this point, the propeller is ready for first tests.
