摘要： The invention aims to get around the problems of size, mass or reliability. To do this, energy is recovered in the exhaust nozzle, converted and recirculated using mechanical and/or electrical power recombining means. An example of an architecture of a turbomachine according to the invention includes a main turbine engine (1) and a heat exchanger (18) positioned in the exhaust nozzle (70) and coupled, via pipes (18a and 18b), to an independent system (16) that converts thermal energy into mechanical energy. This independent system (16) is connected to localized (Z1) mechanical recombination means (20) via a power shaft (15) to supply power to a power transmission shaft (80) according to aircraft requirements.

摘要： The invention relates to a method for maintaining the efficiency and duty of a turbine engine compressor in order substantially to reduce the specific consumption Cs, while guaranteeing a high enough pumping margin with partial load. For this purpose, the invention proposes an optimised method for adapting the airflow to a variable demand for flow or mechanical or electric power in a centrifugal compressor of a turbine engine. The method includes diffusing the airflow (F) through a first annular blade ring (G1) having variable-pitch blades (24), radially bordered by a second annular blade ring (G2) having the same number of fixed-pitch blades (28) with an equivalent extension, guiding the radial extension diffusion by coupling the blades (24, 28) of the two blade rings. According to said method, each blade (24) of the first blade ring (G1) is spun off-axis.

摘要： The invention relates to a method for optimising the specific consumption of a helicopter provided with two turboshafts (1, 2), each one comprising a gas generator (11, 21) provided with a combustion chamber (CC), each of said turboshafts (1, 2) being able to operate alone in the continuous flight mode, the other turboshaft (2, 1) being then in a so-called super-slow mode with zero power and with the combustion chamber lit, said super-slow mode being assisted by a mechanical rotation of the shaft (AE) of the gas generator in this mode, in such a way as to reduce the operating temperature and the fuel consumption of said gas generator.

摘要： The aim of the invention is to optimize the entirety of the drive power available in a helicopter by using an auxiliary motor to supply power to the equipment and accessories of the helicopter that are connected to the engines. In an example of an optimized power transfer architecture for implementing the invention, the main engines (1, 1') and the APU group (8), as an auxiliary motor, comprise a gas generator (2; 81) connected, for the main engines (1, 1'), to the gearboxes (6) and accessory boxes (7) of mechanical, electric, and/or hydraulic power sockets, and connected, for the APU group (8), to at least one power conversion member (83, 84, 11). The power conversion member (83, 84, 11) of the APU group (8) is connected to the equipment and accessories via the gearbox (6) and/or via the accessory box (7) of the main engines (1, 1').

摘要： The invention seeks to reduce the specific fuel consumption Cs of a twin engine helicopter without compromising on the safety conditions regarding the minimum amount of power to be supplied for any kind of mission. To achieve this, the invention plans to make available special means capable of guaranteeing reliable in-flight restarts. One example of an architecture according to the invention involves two turbine engines (1, 2) each equipped with a gas generator (11, 21) and a with a free turbine (12, 22). Each gas generator (11, 21) is equipped with active drive means (E1, E2) capable of keeping the gas generator (1, 21) rotating with the combustion chamber inactive, and an emergency assistance device (U1, U2) comprising near-instantaneous firing means and mechanical means for accelerating the gas generator (11, 21). The control system (4) controls the drive means (E1, E2) and the emergency assistance devices (U1, U2) for the gas generators (11, 21) according to the conditions and phases of flight of the helicopter following a mission profile logged beforehand in a memory (6) of this system (4).
