METHOD AND AIRCRAFT WITH ROTATING LIFTING PLANE EQUIPPED WITH TWO MAIN GAS-TURBINE ENGINES AND AUXILIARY GAS-TURBINE ENGINE OF LESS POWER Russian patent published in 2015 - IPC B64C27/14 B64D35/08 

FIELD: transport.

SUBSTANCE: invention relates to aircraft engineering, particularly, to aircraft power plant designs. The aircraft (1) is equipped with rotating lifting plane (2) and gas-turbine engines (11, 12, 13) for actuating the mentioned rotating lifting plane (2). The aircraft contains two identical two main gas-turbine engines (11, 12), each one of which can work in at least one specific mode associated with main power (PMD, PIU) and auxiliary gas-turbine engine (13) which can work in at least one chosen specific mode producing auxiliary power (PMD', PIU') proportional to corresponding main power (PMD, PIU) with proportion factor (k) not exceeding 0.5. Herewith, the mentioned aircraft has control system (20) for rotating lifting plane actuation due to continuous operation of each main gas-turbine engine (11, 12) while in flight and additionally of auxiliary gas-turbine engine (13) at least during one predetermined specific phase.

EFFECT: lower specific fuel consumption while in cruising flight.
