9. Propeller Design
Propeller blades are made of a new generation of the composite shell. This unit creates a perfect compact
sandwich construction. Rotary and centrifugal forces are transmitted to the propeller hub by an important
structural element, a composite shaped tube that is embedded in the shaft, the root of the blade and the
blade body itself. The tips of the propeller blades are painted in red to highlight the ends of the propeller
while rotating.
The propeller hub is made up of two cast aluminum alloys, which are assembled with M6 screws. Both
halves of the hub tightly clamp the propeller blades and prevent their rotation or vibration.
Propellers of this type series have undergone a number of demanding tests that have proven a high level
of safety in their operation.
Propellers are designed to be fitted to reciprocating piston engines with reduction gear.
The KLASSIC type series of propellers with their performances, properties and safety meets the regulatory
requirements for standard airplane categories.
Propellers are equipped with the spiners made of composite. They are produced in various shapes and
colors, according to the installation dimensions of the particular aircraft and the customer's wishes.
For installation on some aircraft, the propeller can be equipped with 18-100mm duraluminium spacer.

Service life
The propeller service life is not limited when the
scheduled maintenance is observed.
KLASSIC 170/3 propeller is designed for use on piston engines and is operationally verified on ROTAX
piston engines.
ROTAX engines must be equipped with a reduction gear for the KLASSIC series propellers.
Exceeding the operational parameters may cause the heavy damage of the propeller, engine
or reduction gear.
Damaging the propeller may further lead to impairement of its balance and in critical case also
to deformation of the engine mounting.

12. Connecting the KLASSIC 170 Propeller to the Engine
The dimensions correspond to the Rotax 912 engine flange - part number ROTAX 837 282. For attaching
the KLASSIC propeller, use holes on the ø75mm pitch circle.
If needed, the propeller can be equipped with a special duralumin spacer of 18-100mm size.
13. Propeller Reassembly Procedure
The propeller is fully completed and put into airworthiness by Woodcomp Propellers. After performing all
the specified activities, the propeller is ready for transport to the operator.
In order to simplify and reduce shipping costs, the propeller can be disassembled before packing. Although
the procedure of adjusting the propeller on the airplane is simple, an unsafe operation may result in a
state of danger for the integrity of the powerplant and the safety of operation, so that the assembly may
only be performed by an authorized service organization.
13.1. Propeller State Description
Note: All the mentioned positions are linked with the illustrated parts catalogue (Fig. 2 and 3). Individual
parts of the propeller are marked, and are unique their position in assembly.
Both halves of the hub (pos. 1, 2) have on the face marks for relevant propeller blades stamped numbers
1, 2, 3.
Each propeller blade (pos. 3) has on the root a label with the number 1, 2 or 3, which identifies its position
at the hub.
Setting of the spinner (pos. 5) towards backplate (pos. 4) is marked with red dots.
An option of the propeller can be spacer (pos. 6) used to ensure sufficiency distance between propeller
and engine cowling.

13.2. Propeller Blades Assembly
Place propeller blades (pos. 3) to related position in hub (pos. 1, 2) –incorrect positioning is not
permitted!
Using supplied screws (pos. 8) without washers, tighten each blade but allow blade to still rotate. Pull the
blades in direction of centrifugal forces to remove axial play in the locked blades.
13.3. Blade Angle / Pitch Setting
To adjust the angle of the propeller blades, place the hub with blades (pos. 1, 2, 3) on a horizontal plate
(check with a protractor). The angle set by carefully turning of the blades in the propeller hub. Blade
setting angle means the angle between the propeller rotation plane (in this case the horizontal plane on
which is placed the propeller hub) and a tangent to the lower (pressure) side of the blade profile at a
distance of 50 mm (2") from tip of the blade (end of colouring tip). Angle measurement is performed by
applying a suitable protractor or template on the bottom (pressure) side of the blade in that the distance
from the end.
After setting all blades to the desired angle, tighten each of the stems with 4 screws (pos. 8) using torque
of 10 Nm. Screws tighten step by step, cross. After tightening recheck setting of angles of the blades.
In the hole in of front half of the hub (pos. 2) insert the plug (pos. 13). The propeller is ready for
installation on the aircraft.
13.4. Static Balancing
The final stage in production or maintenance the propeller is statically balanced on a precise instrument.
Propeller is balancing without spinner. Spinner assembly with back plate is balanced independently.
To keep adjusted balance, every part must be placed in the same position as before dismantling.
14. Propeller Installation to the Aircraft
14.1. Propeller without Spacer
Mount on engine flange backplate (pos. 4) and afterward propeller hub with blades (pos. 1, 2, 3). Attach
the propeller using 6 screws (pos. 9) with washers (pos. 10) and self-locking nuts (pos. 12). Tighten the
nuts using 22 Nm in the sequence as shown in Fig.1.
After tightening secure screws (pos. 9) in pairs using Ø 0.5mm stainless locking wire.
The spinner (pos. 5) attach on propeller in the position marked by red dots on the back plate - to ensure
fitting the spinner in the correct position. Tighten the spinner using 6 screws (pos. 14) with plastic washers
(pos. 15). Screws secure with Loctite 243.

(pos. 15). Screws secure with Loctite 243.
The tightening torques of the screw connections is only valid for dry, uncoated threads!
15. Handling, Storage and Transport
15.1. Propeller Supply
The propeller is supplied as a complete set, including the fixing elements of the propeller and also the
necessary documentation.
15.2. Handling
The propeller must be handled very carefully so as not to damage it eg by impact.
When transporting the propeller in a disassembled state, its blades must be protected by protective
covers. For safer transport, however, we recommend inserting the propeller into a rigid container
(cardboard, plywood, etc.). The propeller must be placed horizontally on the support supporting the
propeller hub.
15.3. Manner of Storage
During storage, the propeller blades should be protected by protective covers. In the case of long-term
storage, it is recommended to clean the propeller hub and the propeller blades with lukewarm water with
detergent.
The propeller must be placed horizontally on a support supporting the propeller hub or hung at the
attaching holes in the hub.
Climatic conditions: temperature 5° to 25°C and relative humidity up to 80%.
It is forbidden to store the propeller in such a manner that is put on the ends of two blades
and supported by the wall, even for a short time!
15.4. Transport
If the propeller is delivered to the customer in a special cardboard package, it can also be used to return
the propeller for service visits to the manufacturer or an authorized service center.
Note: In case of transport for overhaul, the propeller may be transported in a dismantled state, if the
dismantling was performed by an authorized service center.
15.5. Responsibility for Transport
The producer is responsible for the proper packing of the propeller from the moment of leaving the plant,
until it is taken over by the forwarding company. Then the forwarder takes over responsibility. The client,
when receiving the propeller from the forwarder, should check visually that the packing of the propeller is
not damaged.
In case of packing damage it is necessary to unpack the propeller in the presence of the forwarder, to
check for and claim for any possible damage from the forwarder.
