METHOD FOR DETERMINATION OF DYNAMIC CHARACTERISTICS OF ELASTIC STRUCTURE WITH TANKS PARTIALLY FILLED WITH FUEL SIMULATOR

摘要

The invention relates to the field of experimental studies on the dynamic characteristics of the aircraft, in particular to a model experiment. The purpose of the invention - improved accuracy of determining the dynamic characteristics. A method for determining dynamic characteristics of elastic construction is placed in the pattern models of the wing tanks filled with fuel simulator, and holding frequency bench test, the simulated fuel as used 3-4% ethyl thiophilic type colloid solution, for example gelatin or agar-agar, a test is carried out in two phases, removing the frequency characteristics of the system-wing fuel tank filler in a liquid heated to 50-60RS filler and cured at a temperature of 20 & amp; deg; C filler and the actual dynamic x Characteristics Model elastic structure with partially filled tanks prepared with the correction factors. 1 yl.
