Collection and processing of information

in gas turbine engine systems 

 

These include subsystem for collecting and processing information (sensors, transducers), the formation of programs and algorithms and control (electronic, hydro-mechanical, pneumatic, etc.), Actuators (signal converters, power actuators), the fuel supply (pumps, valves Fuel and etc.).

 

2 osnvnyh work directions

 

The science and practice of creating the SU should be divided into two main areas of work are closely related to each other and significantly affect the results of the development:

  • (1) work on the methods of control of the engine and control system in general, aimed at the formation of methods of influencing the work process. They should allow, taking into account the existing capabilities and limitations, to fulfill a set of numerous and contradictory requirements for the functional characteristics of the engine and aircraft (thrust, efficiency, dynamic properties, gas dynamic stability (GDU), etc.) when external conditions (speed and altitude, temperature, etc.) change. air humidity, etc.) in all operating conditions of the aircraft, ensuring, at the same time, the resource and reliability of the engine and meeting the requirements for operational manufacturability (operating cost). The result of work in this area are programs and control algorithms that make up the algorithmic base of the ACS, in particular, the basis for the functional software of electronic controllers;
  • (2) work on the creation of equipment for control systems and fuel supply. The selection of characteristics and the development of electronic, hydromechanical and other types of regulators, pumps and other elements of fuel systems, sensors, actuators, that is, the entire complex of necessary units is carried out. At the same time, the operability, the required reliability and operational adaptability must be ensured, taking into account the operating conditions and external influences (temperature, pressure, vibrations, overloads, etc.) and the conditions of use of aircraft (AC). The capabilities of the hardware implementation of the ACS affect the choice of control methods.

 

Methods of automatic control of gas turbine engines have been developing since the appearance of engines of this type in aviation as the general theory of control and theory of control of gas turbine engines improve, methods for studying systems (from approximate analytical methods to numerical studies using computers, first analog, then digital) Which puts ever higher demands on management systems) and, finally, technological capabilities of the industry. This made it possible to take fuller account of engine features, which include high dynamism, the dependence of static and dynamic characteristics on engine operating conditions and flight conditions, during which they change in accordance with a significant change in temperature and pressure of air and gas.
