О.І. Khlystun, V.P. Botcharov, О.Z. Haniyev, Т.О. Tereshchenko

Mathematical description of gas-turbine engine bleed air parameters digital controller is presented. The controller’s dynamics is represented in the form of the transfer functions. For this goal difference equations and z-transforms are used. The requirements to the functional tests bench of air parameters digital controller are formulated. The pneumatic diagram of the bench and interface of the monitoring and registration system are presented. The results of bleed air parameters digital controller functional analysis of transport category aircraft pneumatic system are presented, the computer-integrated techniques are used.

Key words: digital controller, aircraft pneumatic system, air parameters controlling, gas-tutbine engine compressor.
