source mode recovery systems

 

 

In SKPZU can be used as all of the above control actions, and a part of them.

Systems must restore the original mode is automatically triggered when the loss of CDB regardless of the reasons of its occurrence. They provide automatic elimination of unstable operation and restoration of the original mode according to the position of the lever engine control.

To register an unstable work in the RAF used the parameters that characterize the appearance of the surge and rotating stall, such as ripple full or static pressure or dynamic pressure in the flow at the outlet of the compressor. The frequency of the pulsations is 8. 150 Hz.

The executive bodies in the SVR are the same device as in SKPZU. In addition, it can be used a device that provides a complete cessation of fuel supply.

The actuators are included for the duration of the signal on the erratic and off through 0,1. .0,2 Seconds after its liquidation.

At the end of the liquidation process instabilities automatically restore the original mode is both normal cycle of pick-up and using special control programs to ensure the minimum recovery time mode.

Values ​​/ skpzu when the desired value 5KU skpzu should be minimal.

To monitor performance and evaluate the effectiveness of available SKPZU used to measure the parameters: reduction of the speed of the rotors A \ and Dp2; time to reach the minimum speed value tnimm and fn2min; tB. The lower values ​​(if required increase in disposable safety factor), the more efficient the system. Changing the engine while working SKPZU.

To evaluate the effectiveness of CBP using the following criteria:

Mathematical modeling SAU GTE

At all stages of development SAU GTE important place is given to mathematical modeling and parametric optimization of ACS on computers. This can significantly reduce the time spent on training and problem solving, improve the efficiency of research to solve problems arising in the process of establishing and operating the engine.

The cycle of works in the field of management can be provided by using a complex of several types of GTE models of different levels of complexity.
