Results of development of the specialized test equipment are described. This equipment (developed by specialists of enterprise “Element”) is the stand-simulator which simulates an electric starter-generator of a direct current and is intended for adjustment and testing in laboratory conditions in full parameters and functions of the block of start and generating which is the development of enterprise “Element” too. The basic characteristics of the stand-simulator are shown and experience and results of its application during development, manufacturing and tests the block of start and generating are covered. This stand-simulator is the hardware-software complex simulating the starter-generator as a system which interacts with the block of start and generating by electrical signals interchange. Questions of formation of mathematical model of the starter-generator which has been integrated in the stand-simulator are reflected. Mathematical model was formed as a result of the starter-generator tests with the real aircraft engine and with the block of start and generating. These tests were fulfilled on the engine test bench of specialized enterprise “Motor Sich”. The structure of the stand is given and is described the same way as the input and output electrical signals which are provided by stand-simulator during the process of the block of start and generating adjustment and testing. The special attention is given to a stage of modernization of the stand-simulator with the purpose of maintenance of checking of cross start and alignment of currents of two starter-generators on two-engine aircraft. Two methods of checking of cross start are applied in the stand-simulator. The one of these methods can be called software-method and the second is so-called hardware-method. The hardware-method is close to the real conditions as much as possible. These two methods are described, advantages and disadvantages of each one are illustrated and the conclusion concerning the using both of them is substantiated. The results of the stand-simulator application for block of start and generating tests are verified by the comparison with the results of the real tests of that block with the starter-generator and with the real engine.
