KievProp produces a range of In-Flight and Ground Adjustable pitch propellers for Sport Aircraft which includes ULM Experimental Aircraft, Bush Planes, Trikes, Paratrikes, Flying Boats, Autogyros, Airboats and snowplanes with diameter of 64.3" - 74.9", left or right rotation, in 3-, 4-, 5-, or 6- blade configurations.
The propellers are designed to be installed on the aircraft powered by (Rotax, Hirth, HKS, BMW TakeOFF, Simonini)with a gear box or belt drive RPM reduction unit and shock absorber style engine mounts. .
Maximum output power on the driving shaft for 3-blades propellers is up to 140 hp inclusively.
Maximum output power on the driving shaft for 4-blades propellers is up to 160 hp inclusively.
Maximum output power on the driving shaft for 5-, 6-blades propellers is up to 180 hp inclusively.
The Basic propeller order includes:
- Hub + its installation kit (bolts and nuts),
- Pitch adjustment device,
- Fastening bolts,
- Log Book, Installation / Maintenance Manual
Additionally propeller can be supplied with:
- Spinner (hub fairing) Ø 226 mm (8.9"),
- Spacer (distance separator) of 15 mm (0.6"), 30 mm (1.2"), 40mm (1.55"), 57 mm (2.25") or 80mm (3.1").
The rropeller is fixed to the engine flange with six grade 8.8 bolts. 75 mm mounting holes are centered on the hub. This is the standard diameter for Rotax and Hirth engines.
Bolt tightening torque: 25 Nm !
A Spacer is used when you need to move propeller away from obstructions such as, the radiator, engine cowling, exhaust system, flaps, etc. For Pusher Aircraft, increasing the distance between wings and propeller reduces noise and possible vibration of wing control elements. It also improves the efficiency of the propeller.
Warranty period of propeller operation – 12 months from the date of purchase, including storage, on condition of proper operation, storage and transportation.
