Tests of high-performance aerobatic propellers

Aeronautical Research and Test Institute (VZLU) completed collaboration on ground and air measurements of a new type of propeller KW-10 within a development program of WOODCOMP company. A contactless system for data transmission from the propeller strain-gauge installation was developed for those purposes. This system allows monitoring real-time signals for ground measurements and in case of air measurements it allows recordings on digital recorder. The system is able to obtain records from the entire flight, including the very valuable information concerning stress of the blades and propeller heads in the course of high acrobatics.

New hydro-mechanical constant speed propeller KW-10 is an important step of WOODCOMP into the field of standard propellers certified according to the building regulations EASA CS-P. Aeronautical Research and Test Institute (VZLU) provides its expertise, technical background and valuable experience to Czech manufacturers of aircraft technology in developing new products to strengthen their market position and ensure closer co-operation of research and development departments with industry.
