A method of assembling an aircraft assembly having a first member and a second member includes drilling at least one first opening through the first member, the at least one opening having a first diameter, and drilling at least one second opening through the second member, the at least one second opening having the first diameter. The method also includes forming a chamfer on the at least one first opening and the at least one second opening, the chamfer having a chamfer diameter, and positioning the first and second members to align the at least one first opening and the at least one second opening. The method further includes drilling the at least one first opening and the at least one second opening to a second diameter, wherein the second diameter is greater than the first diameter.

A method and apparatus for tapping into a pressurized multiple strings of coaxially situated tubulars for wells and/or platforms which have overturned wherein the tapping occurs underwater via a diver or remotely operated vehicle. The assembly includes a tapping tool connectable to the tubular via a saddle connection and an adjustable tapping clamp with adjustable support/locking feet, compression plate with view ports, and angularly adjustable hot tapping system, along with a drill/saw system.

An apparatus and method are provided for integration of drilling and interference-fit pin insertion. The apparatus includes a station switching module, a spindle module, and a pin insertion module. The station switching module is configured to drill and countersink a panel connecting hole. The pin insertion module is configured for interference-fit pin insertion of a hi-lock bolt. Hence, by using the apparatus, after the drilling of a hole to be drilled is completed, the station switching module is rotated by a fixed angle so that station states of the spindle module and the pin insertion module can be switched, the interference-fit pin insertion of the hi-lock bolts can be completed, and the anti-fatigue property and assembly efficiency can be improved.

The present disclosure generally relates to methods and apparatuses for additive manufacturing using foil-based build materials. Such methods and apparatuses eliminate several drawbacks of conventional powder-based methods, including powder handling, recoater jams, and health risks. In addition, the present disclosure provides methods and apparatuses for compensation of in-process warping of build plates and foil-based build materials, in-process monitoring, and closed loop control.

A method for processing a CMC airfoil includes nesting an airfoil fiber preform in a cavity of a fixture that has first and second tool segments, closing the fixture by rotating a first tool segment about a hinge, the closing causing the tool segments to clamp on a tail portion of the fiber preform and thereby conform the tail portion to the fixture. While in the fixture, the fiber preform is then partially densified with an interface coating material to form a partially densified fiber preform. While still in the fixture, one or more cooling holes are drilled into the trailing edge of the partially densified fiber preform. After the drilling, the partially densified fiber preform is removed from the fixture and further densified with a ceramic matrix material to form a fully densified CMC airfoil.

A wheel tub spraying device for preventing rusting of a wheel tub and adjacent body panels includes a pipe that a first end, which is closed. A coupler that is coupled to a second end of the pipe is configured to couple to a tube that extends from a source of pressurized water so that the pipe is fluidically coupled to the source of pressurized water. A plurality of holes that is positioned in the first end of the pipe is configured to increase a velocity of water that exits the pipe through the holes. A user positions the first end of the pipe proximate to a respective aperture of a plurality of apertures that is positioned in a respective wheel well of a vehicle to clean an associated wheel tub of the vehicle. Maintaining the wheel tub clean and dry deters rusting of the wheel tub and adjacent panels.

The present disclosure relates to a drilling device for machining tubes in tube sheets of heat exchangers in a radioactive environment. A retaining plate is clampable in the tubes with at least two retaining fingers on a first side and a first drive, which drives a tool shaft, is arranged on a second side. A tool chuck on a first end side of the tool shaft is connected detachably to the latter, wherein a forward feed of the tool shaft is brought about by a feed device. In addition, the tool chuck is unlockable from the tool shaft by way of an unlocking instrument and the unlocking instrument is controllable by a remote-control device.
