A method for covering an engine inlet includes providing a collapsible cover comprising a connection pin defining an axis; a frame including interconnected arms; and a web. Further, the method includes storing the collapsible cover in a stowed configuration in which the arms are aligned. Also, the method includes rotating the arms from the stowed configuration to an operating configuration in which the arms are radially spaced about the axis, enclosing the frame in the operating configuration with the web to define an interior volume, and placing the cover over the engine inlet.

A suspending tool includes a suspending tool main body that extends to be parallel with an axial direction above a rotor main body, a pair of bearing supporting portions that are disposed at an interval in the axial direction and are detachable from the bearing portions, a pair of seal supporting portions that are disposed inside the pair of bearing supporting portions in the axial direction at an interval in the axial direction and are detachable from the seal portions, and a plurality of diaphragm supporting portions that are disposed inside the pair of seal supporting portions in the axial direction such that the diaphragm supporting portions are disposed at intervals in the axial direction and are detachable from the diaphragms.

A primary lock system for a translating cowl thrust reverser system includes a primary lock having a housing, a lock, and a manual mechanism. The lock is disposed at least partially within, and is movable relative to, the housing and is movable between a lock position and an unlock position. The manual mechanism is coupled to the lock and is configured, in response to a manual input force supplied to the manual mechanism, to: selectively move from a first position to a second position, whereby the lock is selectively moved from the lock position to the unlock position, respectively, and selectively prevent movement of the lock out of the lock position.

A gas turbine engine maintenance stand for a gas turbine engine that comprises modules including an engine core module that houses a high pressure compressor and a turbine module that houses a low pressure turbine. The gas turbine engine maintenance stand has a pair of base beams, each base beam having a first end, a midsection and a second end. The stand has an engine core module support that straddles the pair of base beams at their midsection, the engine core module support having engine core module support arms that are configured to engage opposing sides of the engine core module of the gas turbine engine. The stand also has a turbine module support that straddles the pair of beams adjacent their second ends, the turbine module support having turbine module support arms that are configured to engage opposing sides of the turbine module of the gas turbine engine. The gas turbine engine maintenance stand is useful for disassembling and reassembling modules of a gas turbine engine in order to maintain the gas turbine engine for safety and performance purposes.

Various embodiments include methods for performing maintenance on a gas turbine bearing area. In some cases, a method includes: separating sections of an inlet bellmouth of the gas turbine without removing the sections of the inlet bellmouth from the gas turbine; removing a housing from over a bearing of the gas turbine; mounting a bearing maintenance apparatus adjacent the inlet bellmouth and the bearing; and performing maintenance on the bearing area while the sections of the inlet bellmouth remain separated.

A gas turbine storage container is composed of a horizontal cylindrical shell with openings at two opposite ends of the cylinder, outside is designed with frames to keep it fixed and has straps to install ropes when hoisting. The inside of the cylindrical shell is pumped with inert gas and contains desiccant. The engine is housed in a mount that can be fixed to the inside of the box, and has wheels to make it possible to move it out of the box. A sensor system that measures the temperature and humidity status inside the cylindrical shell can provide information about the quality of the gas stored in the cylindrical shell in real time without opening.

The present invention discloses a system for providing mobile power, in which the required equipment for the power supply system at fracturing fields as well as connection cables and connection hoses are integrated properly, assigned onto three transport vehicles for movement and effectively connected. Intake components and a turbine generation system are combined on a first transport vehicle and installed together, then transported to customer sites directly, thus saving the installation time at the user sites. The two different designs on the locations of an exhaust stack and an exhaust silencer not only meet the requirements of road transportation, but also meet the requirements of exhaust gas emission during operations.

A modular flooring system comprises a modular floor surface and a plurality of stackable, three-dimensional modular interior design components (MIDCs). The modular door surface can comprise an array of discrete, raised, low-profile, receiving panels that can be rectangular in shape. MIDCs can be securely and interchangeably placed on any group of one or more adjacent unoccupied receiving panel and they east also be stackable, such that various different floor layouts can be created. Bach of the MIDCs may comprise a lower surface recess that fits over a group of one or more adjacent raised receiving panels. A first MIDC may have an raised lip on a top surface such that the lower surface recess of a second MIDC fits over, separately and interchangeably, one (or more) of the raised receiving panels and the raised lip on the top surface of the first MIDC. The MIDCs can comprise a storage cube MIDC (square or rectangular cube) as well as specialized MIDCs, such as a commode MIDC, a sink MIDC, a cooler MIDC, and a tile MIDC, etc. In such a manner, a user of the modular flooring system could locate the MIDCs on the floor surface and/or stack them to configure a preferred layout. Moreover, the MIDCs could be rearranged later to design a new layout.

An energy storage includes a first container including an inner space, a plurality of pressure vessels for compressed air that are stacked in rows inside the inner space of the first container, a tank containing a heat transfer fluid arranged inside the inner space of the first container, a compressor adapted to compress air, and a plurality of pneumatic ducts for compressed air connected to the compressor. The plurality of pneumatic ducts includes a plurality of heat exchangers adapted to enable a heat exchange between compressed air contained in the plurality of pneumatic ducts and heat transfer fluid contained inside the tank. The plurality of pneumatic ducts is connected to the plurality of pressure vessels supplying pressure vessels with compressed air, an electric turbine connected by the plurality of pneumatic ducts with the plurality of pressure vessels supplying compressed air for rotating the electric turbine to generate electric current.
