The possibility
of maintenance the maximum power values for turboshaft aircraft engine in the conditions of warm
temperatures of ambient air by
use of the law of control
with indirect determination
(recalculation through measured parameters) of the total gas temperature
upstream the compressor turbine is
considered. The appropriateness and application range of the given
control law are defined. The design procedure used in practice for
indirect determination parameters of the total gas temperature upstream the compressor
turbine by measured parameters
for one of turboshaft aircraft engines, which are
developed by JSC "Motor Sich", is described.
Key words: turboshaft engine, warm temperature of ambient air, power, gas temperature, law of control, indirect determination.
