Aircraft modal testing at VZLÚ
Technical article
An upgraded system for modal tests used at the VZLÚ is briefly described. PRODERA's modified software for test control and VZLÚ's software for final data processing were successfully applied for modal tests of L-610G and L-159 aircraft. A method for evaluation of vibration mode shapes measured at an L-610G test is shown as an example. Investigation of dynamic characteristics of hydraulic actuators needs a special procedure. A solution used at VZLÚ is shown in this article.
