Abstract: A DC-to-DC converter for an electrical aircraft propulsion system designed to be connected in series with an electrical energy storage unit of the electrical propulsion system. The DC-to-DC converter includes an inverter, a transformer and a rectifier, and further includes a current source that is connected to the rectifier and is configured to control the power passing through the DC-to-DC converter. The transformer includes a primary and two secondaries, the two secondaries sharing a common terminal designed to be connected to a high-voltage DC bus of the electrical propulsion system and two other terminals that are connected to the rectifier. The rectifier includes two arms including at least two transistors that are each in series and are connected, on the one hand, to the two other terminals of the transformer and, on the other hand, to the current source.

Abstract: Disclosed is an air intake manifold including a heat exchanger built into its body and including at least two ducts for supplying and removing heat-exchange liquid, the ducts extending through the wall of the body of the manifold with a liquid-tight seal and an airtight seal, which are distinct and mutually offset along the longitudinal axis of the relevant duct being created on each of the ducts. The unit creating the liquid tight seal is arranged between the relevant duct and a circulation pipe connected to the free end of the duct. The unit creating the airtight seal is positioned between the relevant duct and the body of the distributor. A leakage path associated with the liquid-tight seal is created between the latter and the airtight seal.

Abstract: A connecting system for an electronic device is disclosed herein. The connecting system may comprise a connector port including an alignment feature and two or more conductive traces corresponding to contacts of a dock interface. The connector port may be rotatable relative to the dock interface with at least two conductive traces arranged in a manner such that the contacts are maintained in contacting relation with the conductive traces along a contact path when the electronic device is rotated relative to the dock interface. The connector port may further include one or more nonconductive separating spaces that separate the at least two conductive traces along the contact path. The connecting system may comprise a rotation stop arranged such that the contacts are prevented from having contacting relation with conductive traces other than a conductive trace to which the contact corresponds and with which the contact is aligned.

Abstract: Disclosed is an intake distributor for an internal combustion engine that includes an integrated heat exchanger. This exchanger includes a support plate that ensures its rigid mounting in the distributor and peripheral seal that form an essentially continuous circumferential airtight barrier between the exchanger and the distributor, peripherally dividing the interstitial volume into two. The subdivision plane of the interstitial volume is perpendicular in relation to the plane of the support plate, and the peripheral seal consist of two complementary components that are connected to one another and made integral with the exchanger.

Abstract: A turbine engine including a stator including variable-pitch vanes that are controlled stage by stage. An actuator ring connected by crank-arms to the variable-pitch vanes is coupled to at least one adjacent specific drive unit in a general form of an actuator.

Abstract: An unducted fan of variable-pitch blades including roots engaged from outside in respective radial housings of an annular rotor element and guided to turn about their respective axes by pairs of rolling bearings, one of which is carried by an annular segment of a cylindrical skirt mounted in a groove of the annular body and by a locknut screwed onto the cylindrical skit. The bearing is covered externally by a ring including outer dog-clutch teeth co-operating with inner dog-clutch teeth of the housing to hold the ring axially in the housing. A blocking mechanism is engaged between the teeth of the housing and the teeth of the ring preventing the ring from turning and preventing the ring from being withdrawn axially from the housing.
