FIELD: engines and pumps.
SUBSTANCE: invention relates to aircraft engineering, particularly to method of controlling aircraft gas turbine engine reverse thrust during aircraft roll-out. In compliance with proposed method, static pressure receivers are arranged on surfaces of outer and inner engines nacelles, their readings being compared to those of air pressure receiver (APR) during aircraft roll-out using thrust reverse. In case, there is no mismatch between aforesaid readings, inner engines thrust is kept invariable. In case, there is mismatch between readings of static pressure receivers arranged on the surface of nacelles of inner and outer engines, as well as between the readings of static pressure receivers fitted on outer engine nacelles surface and those of AVR, inner engines reverse thrust is reduced so that there are no aforesaid mismatches, i.e. Pst.out-Rst.inn≠0, Pst.out-Rst.AVR ≠0, where Pst.out, Pst.inn is static pressure on outer and inner engine nacelles, Pst.AVR is static pressure received from AVR. Proposed method comprises also comparing the readings of static pressure receivers arranged on outer and inner engine nacelles surfaces with AVR readings. Note that inner engine reverse thrust is varied during entire landing run of aircraft till thrust reverse outage.
EFFECT: improved landing performances and protection of engines against reverse jets and ingress of foreign matters.
