Fixed-pitch wooden aircraft propeller family

The Wood propellers is a fixed-pitch wooden aircraft propeller from Sensenich with aerospace-grade material. Sensenich wood propellers are fixed-pitch wooden propellers for manned aircraft, made by Sensenich Propeller. The range is built for light sport, experimental and antique aircraft, and it forms the wood line of the company's aviation propellers next to its aluminium and composite ground-adjustable propellers.

The family has 24 models in the wood category, with designations running from W54JV5L to W98AA. Models are matched to specific engines, and the maker's engine filter lists the Continental O-200, Jabiru 2200, Jabiru 3300, Lycoming O-290, Lycoming O-320 and Lycoming O-360. Pitch is selected for the aircraft type, the engine rating and whether the owner prefers climb or cruise performance, so the correct model depends on the airframe and engine combination rather than on diameter alone.

Construction is described in detail for the W54JV5L-G series, which the maker designed for high-performance, high-rpm direct-drive engines, with tailored airfoils and pitch distribution. Aircraft birch is used, and the number of laminations is chosen to give strength and dimensional stability under the loads of flight. The leading edge is protected by an inlaid urethane edge cast in place on the blade, which the maker says causes no aerodynamic penalty. Fiberglass covering can be added for protection against the environment and abrasion, and the maker recommends it for rough fields and pusher aircraft. The suffix G after the pitch value marks a fiberglass blade wrap, intended for operation from grass strips.

Quality control is part of the offer. Sensenich states that its propellers are manufactured under strict production certificate standards, with material certification and a 48-point conformity inspection for each experimental-category propeller.

For installation, the product pages link a Certified Wood Aircraft Propeller Application Guide and installation instructions for a standard flanged shaft. The material is wood, the pitch type is fixed, and the platform class is manned aircraft. These propellers do not belong to the unmanned or eVTOL propulsion class.

Typical applications are home-built and experimental aircraft such as the Sonex, Waiex and Onex family, light sport aircraft with Jabiru engines, and antique aircraft with Continental or Lycoming engines that need a fixed-pitch wooden propeller.
