An airfoil component for attaching to a cropped airfoil is provided. The cropped airfoil comprises a cropped airfoil attachment section and a cropped first side opposite a cropped second side, which each extend axially between a cropped first edge and a cropped second edge to define a cropped chord length. The airfoil component comprises a body having a component first side opposite a component second side. The body defines an attachment section for attaching the airfoil component to the cropped airfoil at the cropped airfoil attachment section. The attachment section extends axially between a component first edge and a component second edge to define a component chord length, and the attachment section is oversized with respect to the cropped airfoil attachment section such that the component chord length is longer than the cropped chord length. Systems and methods also are provided.

Airfoil joining apparatus and methods

A friction welding method includes: applying axial force to first and second metallic components so as to force the components against each other at an interface therebetween, while oscillating the two components relative to each other in a cyclic motion, so as to generate friction and heat at the interface; rapidly stopping the cyclic motion; and applying a spike in the axial force to complete a weld between the first and second components.

Friction welding method

A vehicle track play set includes a base, a plate coupled to and extending upwardly from the base, and first and second tracks extending along the plate toward the base. The first track includes a first curved portion extending outwardly from a first surface of the plate and a second curved portion extending outwardly from an opposite second surface of the plate. The first track extends through a first opening in the plate between the first and second curved portions. The second track includes a third curved portion extending outwardly from the second surface and a fourth curved portion extending outwardly from the first surface. The second track extends through a second opening in the plate between the third and fourth curved portions.

Toy vehicle track play set

A method for repairing a degraded bolt hole in a casing flange by reaming and removing at least some corrosion on an inside and around the hole to form a reamed hole, mounting the flange to float relative to upper and lower electrodes of a welding machine, radially and axially clamping an area of the flange surrounding the reamed hole, placing upper and lower filler slugs in the reamed hole, placing the electrodes against upper and lower filler slugs and applying a welding current through the electrodes while applying pressure to the filler slugs with the electrodes and resistively heating and melting the filler slugs to form a weldment, and pulsing the welding current on and off. Pulsing may be performed with progressively increasing amounts of current. In situ tempering under the pressure of the electrodes may be performed on a substantially liquid pool formed by the welding current.

Resistance weld repairing of casing flange holes

An infant support structure includes a support frame having a lower member configured to engage a support surface. First and second spaced arcuate posts extend upwardly from the lower member, each of the posts having a distal end portion. A seat portion is disposed between and coupled to the posts. A first end of a toy bar is secured to the distal end portion of one of the posts, and a second end of the toy bar is secured to the distal end portion of the other of the posts.

Reconfigurable infant support structure

A fastener system includes a toy product, a support platform, and a plug that engages a keyhole formed into the product. The plug includes a base and a pronged key extending from the base. The support platform includes a through-hole that permits the passage of the key into the packaging. One or more integrally-formed biasing members are located on the base of the plug to draw the key toward the product and create a secure connection. The pronged key may be formed from a plastic material and configured such that it plastically deforms but remains attached to the key when and predetermined force is applied to the key to pull the key from a misaligned position with respect to the key hole.

Product packaging with releasable fastener

A child retaining structure includes a wall assembly defining a child receiving area, a platform disposed within the child receiving area, and a support member connected to the wall assembly and supporting the platform. The support member and the platform are reconfigurable between a raised position so that the child retaining structure functions as a bassinet, and a lowered position so that the child retaining structure functions as a playpen, or alternatively, as a playhouse.

Reconfigurable child retaining structure

A method for bonding airfoil sections includes aligning upper and stub airfoil sections having upper airfoil pressure and suction sides and stub airfoil pressure and suction sides respectively, pressing together upper and stub airfoil cross sections at upper and stub airfoil distal ends of the upper and stub airfoil sections respectively, and then resistance welding, preferably solid state resistance welding, the upper and stub airfoil sections together along the upper and stub airfoil cross sections by passing electrical current across the upper and stub airfoil cross sections. The upper and stub airfoil sections may be clamped between pressure and suction side upper airfoil electrodes and between the stub airfoil pressure and suction sides respectively. The method may be performed while the stub airfoil section is attached to an airfoil carrier such as a rotor disk rim, a gas turbine engine drum, or a gas turbine engine blade platform.

Solid state resistance welding for airfoil repair and manufacture

A fastener system includes a toy product, a support platform, and a plug that engages a keyhole formed into the product. The plug includes a base and a pronged key extending from the base. The support platform includes a through-hole that permits the passage of the key into the packaging. One or more integrally-formed biasing members are located on the base of the plug to draw the key toward the product and create a secure connection. The pronged key may be formed from a plastic material and configured such that it plastically deforms but remains attached to the key when and predetermined force is applied to the key to pull the key from a misaligned position with respect to the key hole. The key may also be formed as two prongs, each of the prongs including a first portion positioned transversely with respect to the shaft and a second, canted, portion extending between the first portion of the prong and the distal end of the shaft, the canted portions of the prongs intersecting at a line proximate the distal end of the shaft, such that the prongs deform or move towards one another along the intersecting line but remain attached to the plug when and force of at least about 20 pounds is applied to the plug to pull the plug and prongs from a misaligned position with respect to the keyhole.

Methods for making near net shape airfoil metal leading edge protective strips including providing a high temperature additive manufacturing device; providing a tooling system having a mandrel; a metallic cladding applied to the mandrel; and at least one cooling channel associated with the mandrel applying a metallic deposit to the mandrel having the metallic cladding using the high temperature additive manufacturing device; and concurrently removing heat from the mandrel using the at least one cooling channel to produce the near net shape airfoil metal leading edge protective strip.
