Paper Abstract

Helicopter's blade during its rotation accomplishes a complex spatial movement and deformation. This report is devoted to Blade Deformation Measuring System (BDMS) which was developed to measure parameters of the real-scaled blade movement and its bending-twisting deformation. This system operates under videogrammetry principles. The basic principles of registration of video-images and processing of results of measurements are stated. Brief description of the system design is given. The results of the laboratory investigations of system features are discussed as well. This system was tested during experimental investigations of blade deformations of the real upper rotor of Kamov-26 helicopter with radius 6.5 m on the VP-5 rotor test facility in TsAGI's T-101 wind tunnel. The tests have confirmed serviceability of system and have shown opportunity of twist deformation measurements of the blade with a root-mean-square error lower 3 - 6 angular minutes and bend deformations measurements with an error of 0.3 - 0.6 mm. The technique of calibration of Blade Deformation Measurement System and appropriate software had been developed and tested.
