Abstract:
An ice liner assembly for a fan containment case for a turbofan gas turbine engine is disclosed. The disclosed ice liner assembly includes a plurality of arcuate panels arranged end to end to form a cylindrical liner that is disposed within the fan containment case and aft of the fan and abradable strip liner that circumscribes the fan. Because the plurality of arcuate panels are arranged end to end fashion, the ice liner assembly includes a plurality of splice joints, or a joint between two abutting ends of two arcuate panels. The splice joints are reinforced with molded polymeric splice support cores that are substantially lighter and less expensive than currently employed high density aluminum honeycomb core materials.
Abstract:

Abstract:
Carter (10) de turbomachine, comportant une paroi (12) sensiblement cylindrique et un panneau annulaire (18, 20) monobloc d'isolation acoustique monté à l'intérieur de la paroi, le panneau comportant une surface annulaire radialement externe en regard d'une surface annulaire radialement interne de la paroi, caractérisé en ce que la paroi comprend sur sa surface annulaire interne des premiers organes (28) en saillie qui sont en appui axial sur des seconds organes (26) en saillie de la surface annulaire externe du panneau et qui sont fixés à ces seconds organes de manière démontable.
Abstract:
A blade off protection system provides a pass through panel and a stop panel. The pass through panel and the stop panel are multi-layered panels that provide one or more fire resistant layers, energy absorbing layers, and ballistic layers. The pass through panel utilizes adequate layers to absorb a portion of the energy from a separated blade, while still allowing the separated blade to pass through the pass through panel. In contrast, the stop panel utilized adequate layers to prevent the separated blade from penetrating through the stop panel. The blade off protection system may optionally include a metal foam to further assist in absorbing the impact energy from a separated blade.
Abstract:
A filter assembly (6) comprises a mounting support (11) defining a fluid outlet opening in the support, a filter device (9) extending across the opening, a fastening arrangement (12) operative to locate the filter device against a seat (11a) of the mounting support (11) so that the filter device (9) extends across the opening for filtering a fluid medium flowing through the outlet opening and the filter device (9), and a pre-filter device (8) secured, between the fastening arrangement (12) and the filter device (9), by the fastening arrangement (12), for pre-filtering fluid medium flowing successively through the upstream pre- filter (8) and downstream filter device (9). The pre-filter device (8) comprises a filter mounting plate (15) located upstream of the filter device (9) and held there by the fastening arrangement (12), relative to the fluid flow direction, and at least one filter element (16) removably mounted on the mounting plate (15), to enable the filter element (16) to be removed and replaced by a replacement filter element, without the need to discard the pre-filter device as a whole, including the mounting plate. Also disclosed herein are the filter mounting plate (15) itself, with and without the removable filter element (s) (16).
Abstract:
This invention relates to aircraft turbine engine for preventing an aviation accident by segregating F.O.D. entering the engine during air intake. It is to provide protection apparatus for an turbine engine that does not interfere with the intake air flow while providing means to separate birds, hail and sands etc. The centrifuge (2) is disconnected with the shaft of turbine engine (10) for avoiding engine failure due to extreme vibration shock and rotated freely with the flow of intake air to generate a centrifugal power by utilizing several fans (3) on the surface of elliptical shell (4), and it can be operated only at the time of landing, take-off or emergency with an automatic controlled hydraulic system for avoiding aerodynamic drag and waist of fuel during cruise. Also, it has advantages to increase mechanical life of turbine engine with clean air and thrust power with improving compression effect on the structure of centrifuge.
Abstract:
A Foreign Object Damage (FOD) detection system is disclosed for detecting and analyzing ultrasound or stress waves emitted when an object enters the intake of a turbine engine and impacts one or more of the blades in the engine. Upon detection the FOD detection system can immediately inform the operator, inform another electronic device (computer, etc.) and/or latch the event for review by maintenance personnel. The detection system generally consists of one or more stress wave sensors and an electronic assembly to process the stress wave signal received from the sensor(s). The electronic assembly is in communication with the sensor(s) via conventional cabling.
