PROPULSIVE ASSEMBLY COMPRISING A MAIN ENGINE AND AN AUXILIARY ENGINE

摘要

The present invention relates to a propulsion assembly (2) is configured to provide a thrust for takeoff, and a thrust of the top of which is mounted a and comprising: - a main motor (3), configured to provide a main thrust during the take-off regime and the speed of the crown is mounted with a ratio (qtcomb) between a temperature at the output of the combustion chamber (36) in a condition of operation of the top of which is mounted (tcomb (toc)) and a temperature at the output of the combustion chamber (36) in a condition of operation of the take-off (tcomb (tkoff)) is between 0.90 and 1.10, for example between 1.00 and 1.05, and - an auxiliary motor (4), which is separate from the main engine (3) and configured to provide a thrust of the auxiliary in order to complete the main thrust of the main engine (3) for at least the take-off regime.
