摘要:
An exhaust section for an aircraft gas turbine engine includes an exhaust nozzle in a downstream serial flow relationship with the gas turbine engine having a fan section, a compressor section, a combustion section, a turbine section, and an exhaust section. The compressor section compresses intake air from the fan section, which is mixed with fuel and combusted into hot gases in the combustion section. The hot gases drive the turbines of the turbine section, and are expelled from the gas turbine engine at the exhaust section.

A hybrid propulsive technique includes providing a flow of a working fluid through at least a portion of an at least one jet engine. The at least one jet engine includes an at least one turbine section, wherein the at least one turbine section includes at least one turbine stage. The at least one turbine stage includes an at least one turbine rotor and an at least one independently rotatable turbine stator. The hybrid propulsive technique further involves extracting energy at least partially in the form of electrical power from the working fluid, and converting at least a portion of the electrical power to torque. The hybrid propulsive technique further comprises rotating an at least one at least one independently rotatable turbine stator at least partially responsive to the converting the at least a portion of the electrical power to torque.

A thrust reverser device for a turbojet engine nacelle includes a mobile cowl movably mounted to translate between a closed position which the mobile cowl covers grids deflecting some of the air flow of the turbojet engine and an open position in which it opens a passage and uncovers the grids. The mobile cowl is associated with a blocking flap to pivot between a retracted position and a blocking position corresponding to the open position of the mobile cowl. The blocking flap is fitted with at least one lever forming a drive mechanism which includes at least one adjustable-stiffness shock absorber.
