055306000 | AIRCRAFT ANTI-INGESTION MEANS (E.G., AIRCRAFT DEBRIS GUARD) | 9 |
20090007528 | ENGINE INTAKE SYSTEM WITH ACCESSIBLE, INTERCHANGEABLE AIR FILTERS - An air induction system for an engine to remove contaminants from intake air prior to delivery to the engine. The system includes a filtering unit having barrier filter panels attachable to a mounting frame. The filter panels are interchangeably usable. A juncture between first and second filter panels and the mounting frame is located at a region of relatively lower quantity of intake air flow. The juncture includes lugs on the filter panels which facilitate interchangeability. An opening above the filtering unit permits easy installation and removal of filter panels. | 01-08-2009 |
20100107576 | COMB FOR INLET BARRIER FILTER SYSTEM - An inlet barrier filter system for mounting on an aircraft to filter air prior to intake into an engine of the aircraft includes a frame having at least two curved frame members defining an opening. A filter element has a curved inward face and is received in the opening of the frame. The filter element includes filter media having pleats. A comb is attached to the frame and includes spaced-apart teeth that support the pleats. The comb is curved to generally conform to the curved inward face of the filter element. | 05-06-2010 |
20100236200 | System for inertial particles separation - The system for inertial particle separation removes particulate matter, such as sand, from an air stream, such as that drawn into a turbine engine. The system includes first and second walls spaced apart and positioned within a housing of the turbine engine. The first wall is in the form of an airfoil with variable geometry. An annular air flow path is defined between the first and second walls. The air flow path leads inwardly from an ambient inlet and turns to an outlet. A splitter member is positioned between the first and second walls. A scavenge flow path is defined between the splitter member and the first wall. An inlet thereof is in communication with the ambient inlet, and a filtered flow path is defined between the splitter member and the second wall. The splitter member is also in the form of an airfoil having a variable geometry. | 09-23-2010 |
20130305668 | Debris Intrusion Shield for Jet Engine Applications - The Debris Intrusion Shield for Jet Engine Applications is a prolate hemispheroid metallic assembly installed at the intake of a jet engine. The assembly is designed and intended to limit or prevent the intrusion of solid or semi-solid objects into the engine intake while on the ground or in-flight. All elements of the assembly are arrayed symmetrically about the longitudinal axis of the engine. The assembly is constructed of four basic parts. Tubing is positioned as a radial array about the engine circumference, and serves as the primary debris deflection element. The engine mounting collar serves as the aft point-of-attachment of the assembly to the engine nacelle, and as the aft mounting point for the radial array of tubing. The forward mounting fixture serves as the forward point of connection for the tubing elements. The forward mounting fixture cover serves as a protective cover for the electrical anti-icing elements located at the forward surface of the forward mounting fixture. | 11-21-2013 |
20140202121 | CONICAL LIGHT FOD MOMENTUM PARTICLE SEPARATOR PROTECTOR - A system for preventing foreign objects from entering an air unit of an aircraft is provided including a reverse J-tube mounted to a wall of the ram air header. The first end of the reverse J-tube defines a portion of a cool fluid flowpath. The ram air header also includes a particle separator that is removably mounted to the first end of the reverse J-tube. The particle separator prevents foreign objects from entering the cool fluid flowpath. The particle separator has a generally conical shape. An airflow, opposite the direction of the cool fluid flowpath removes foreign objects from a surface of the particle separator. | 07-24-2014 |
20140237954 | PARTICLE SEPARATOR - One embodiment of the present disclosure is a unique particle separator. Another embodiment is a unique aircraft. Another embodiment is a unique inertial particle separator. Other embodiments include apparatuses, systems, devices, hardware, methods, and combinations for aircraft, engines and particle separators for aircraft and engines. Further embodiments, forms, features, aspects, benefits, and advantages of the present disclosure will become apparent from the description and figures provided herewith. | 08-28-2014 |
20140260127 | INTERCHANGEABLE INLET PROTECTION SYSTEMS FOR AIR INTAKES OF AIRCRAFT ENGINES AND RELATED METHOD - An inlet protection system for filtering air prior to entry into an air intake of an engine of an aircraft includes interchangeably a particle separator panel and a barrier filter panel. The barrier filter panel is adapted to be mounted conformal to the contour of the aircraft and to be interchangeable with the particle separator panel. The particle separator panel has an outer skin and a plurality of particle separators. The outer skin has an opening disposed along a portion of it to discharge filtered particles from within the removable panel directly outward therefrom. | 09-18-2014 |
20150121821 | Jet Engine With Deflector - An air inlet deflector for a structure having an air inlet. The deflector may be retractable within the structure, may be integrally formed with the structure, and may prevent the structure from ingesting foreign matter, such as birds. The deflector may include a series of ribs, spokes, or vanes that may vary in width and/or thickness from fore to aft, and/or may be curvilinear in one or more planes of view, and/or may serve double duty as inlet vanes for redirecting inlet air. | 05-07-2015 |
20150322858 | AIRPLANE ENGINE BIRD STRIKE PROTECTION GUARD - An aircraft engine guard, for protecting an aircraft engine against ingestion of large objects, includes a generally cone-shaped body, a base section of the rear end of the guard body and a dome section at the distal forward end of the guard body, at least three, vertical, peripherally extending walls located between the base and the dome section, with successive ones of the peripheral walls having different peripheral dimensions, peripherally cylindrical, with the dimension increasing from the base toward the dome section. A plurality of air intake openings are defined in and between the peripheral walls with at least one dimensional size which is small enough to prevent having birds from being able to pass through the guard into the aircraft engine. | 11-12-2015 |
