Special Issue Information

Dear Colleagues,

Current trends in aviation greatly expand the use of highly integrated, increasingly autonomous air vehicles, with distributed engine control systems (DECS). Such systems allow for optimizing engine performance by enhancing propulsion control architecture. In DECS, each system element (i.e., sensors, actuators, and controllers) individually connects to the network and has multiple functions. Some of them require real-time communication for control while others may be less time critical. The weight of wiring and need for cooling are significantly reduced in the engine controlled by a DECS when compared to the traditional centralized FADEC.

Implementation of DECS using advanced sensing techniques, high temperature electronics and open data communication will reverse the growing trend of increasing ratio of control system weight to engine weight and will also be a major factor in decreasing overall cost of ownership. Challenges of implementation include need for validation of engine test cell proven sensing techniques, high temperature electronics (located on or close to the sensing element), development of simple, robust communications (simplifying and reducing the wiring harness), and power supply for the on-board distributed electronics. With the limitations of standard silicon technology for current smart sensors, newer material technologies such as Silicon on Insulator (SOI) and/or Silicon Carbide (SiC) electronics are required. This Special Issue aims to include selected papers presented at NATO AVT-357 Research Workshop to be held in Berlin, Germany, during the spring 2021 AVT Panel Business Meeting Week (17–21 October, 2021) but is also open for general submissions (outside the workshop).

Self-oscillations are one of the common problems in the complex automatic system, that can occur due to the features of the workflow and the design of the governor. The development of digital control systems has made it possible to damp self-oscillations by applying complex control laws. However, for hydromechanical systems, such way is unacceptable due to the design complexity and the governor cost. The objective of this work is to determine the parameters of the hydromechanical free turbine speed controller, ensuring the absence of self-oscillations during ground tests of the turboshaft engine with a hydraulic dynamometer. The TV3-117VM engine (Ukraine) with the NR-3VM regulator pump (Ukraine) was selected as the object of the study. However, self-oscillations can also occur in any modifications of the TV3-117 engine with any NR-3 regulator pump. The results of the research may be of interest to engineers and scientists who investigate the dynamics of automatic control systems for similar engines. The paper analyses the nonlinear features of the empirical characteristics of the FTSC leading to self-oscillations of the engine speed. The authors propose the mathematical model of the automatic control system dynamics, which takes into account all the features of the engine and regulator pump. It is shown that the load characteristics of the water brake and the helicopter main rotor can differ significantly. Research of the dynamic characteristics of the TV3-117VM engine was carried out. The analysis showed a good agreement between the calculation results and the field test results, and made it possible to determine the parameters of the controller, which lead to self-oscillations during test. Two cases are considered. The first case includes ground tests of the engine with a water brake; the second case—flight tests of the engine as part of the helicopter’s power plant. The data obtained make it possible to develop recommendations for adjusting the hydromechanical governor without testing it on the engine. Full article
