A segmented augmented turbine assembly for generating electricity from a fluid in motion, the assembly comprising a segmented annular ducted channel extending between an inlet receiving the fluid and an outlet, the channel comprising a convergent accelerating the fluid, a segmented turbine-rotor section comprising blades and guide vanes rotating about a central shaft coupled to a generator, and a diffuser section configured to decelerate the fluid, wherein the channel comprises solid inserts attached to an outside face of the turbine-rotor section, the flow stream passing through open flow-through segments positioned between the solid inserts.

An inlet shield with a first portion that is configured to be secured to an inlet of a turbocharger, and a second portion that is configured to be removably coupled to the first portion via magnets, wherein different second portions may have different mesh layouts allowing a consumer to choose different levels of protection and air flow based on desired use.

A cover for an intake of an air-breathing engine in a missile is disclosed. The cover comprises a closure for closing the inlet so as to prevent ingress of debris; and a fastening attachable to an aircraft-mounted launcher and configured such that the cover remains attached to the aircraft on launch of the missile.

A system and method of an airflow control system for a vehicle is described herein. The airflow control system (100) includes an airflow housing (120) defining an airflow passageway (125) extending between a bypass opening (122) and an intake outlet (124). The airflow housing also defines a duct opening (126) positioned between the bypass opening (122) and the intake outlet (124). The intake outlet (124) may be in fluid communication with an engine intake (12) of the vehicle such that air passes from the bypass opening (122) and/or the duct opening (126) to the engine intake (12). The airflow control system (100) also includes a movable duct (160) movably connected to the airflow housing (120) to selectively allow or prevent air passage through the duct opening (126) and into the engine intake (12), and further includes a bypass door (140) movably connected to the airflow housing (120) to selectively allow or prevent air passage through the bypass opening (122) and into the engine intake (12).

A deflecting device for protecting a jet engine of an aircraft from damage caused by a bird strike. The bird strike deflection device attaches to an opening in the front of a cowling of the jet engine to shield an engine air intake from ingesting a bird that would otherwise damage the engine. A conically shaped screening portion having an open mesh pattern is attached to the cowling in a convex orientation. A perimeter of the screening portion terminates in a rim sized to fit the engine intake opening in the cowling. The rim may be directly attached to the cowling or an attachment flange may connect the rim to the cowling. The deflecting device may be completely removable from, hingedly attached to, or integrated directly into the cowling.

A checking method for checking a power plant of an aircraft, the power plant comprising at least one engine and an air inlet for feeding said at least one engine with air, the power plant including a cloggable filter filtering the air upstream from the engine. An aircraft power check is performed by: determining, in flight or on the ground, the current power actually being developed by the engine without making any allowance for any power losses resulting from the engine being installed in the aircraft or from a level of clogging of the filter, the aircraft power check being considered as being successful when the current power is greater than or equal to a guaranteed minimum power.

An air intake system for an aircraft, which is switchable between a performance mode and a filtered mode, includes a duct forming filtered air inlet slits. The air intake system also includes interconnected gills adjacent to the filtered air inlet slits. The gills are movable between various gill positions including a closed position substantially covering the filtered air inlet slits and an open position substantially exposing the filtered air inlet slits. The air intake system also includes an actuator configured to move the gills into the closed position in the performance mode and the open position in the filtered mode.
