Abstract: An energy-absorbing underrun protection system for a vehicle. The energy-absorbing underrun protection system is comprised of a deformable construction adapted for deforming along a longitudinal axis to absorb crash energy. This deformable construction has a torque arm member extending substantially perpendicularly therefrom for receiving an impact load offset from the longitudinal axis and bending the deformable construction toward the impact load.

Abstract: An underbody crash device for a vehicle. The underbody crash device comprises a pillar member attached to the vehicle. The vehicle has a primary load path for absorbing crash energy in a collision. The pillar member is movable to a deployed position for supporting the vehicle directly on the ground and positioning the primary load path to increase crash energy absorbed therein.

Abstract: An automotive vehicle front structure includes upper and lower siderails and a structural link extending from the upper and lower siderails, with the structural link having a pivotable connection to the upper siderail and a rigid connection to the lower siderail, such that energy absorption provided by the structure may be tailored by varying the character of the joint between the structural link and the upper siderail.

Abstract: A method of repairing a metallic component, such as a superalloy turbine blade or turbine nozzle, includes the step of preparing the component by stripping the protective coatings from the component. The component is then pre-conditioned for welding by a first hot isostatic process. Once the conditioning sequence is complete, the component is welded using any of a number of welding techniques and by adding weld fillers to the weld area. After the welding step, the component is sealed by a second hot isostatic process treatment performed at conditions similar to the first hot isostatic process. The component is finally prepared for re-entry into service.

Abstract: Accordingly, the present invention provides a method for joining metallic members, which can be used to join component sub-assemblies. Further, the present invention provides a method for repairing a component by replacing a damaged portion and re-inserting a replacement section. In general, the present invention provides in one embodiment a method for joining metallic members comprising: preparing a surface of a first metallic member, thereby providing an oxide-free surface; preparing a surface of a second metallic member, thereby providing an oxide-free surface; applying pressure to the first and second metallic members, thereby forcing the surface of the first metallic member and the surface of the second metallic member together and forming a joint area; sealing an outer edge of the joint area; and subjecting the members to a hot isostatic process operation.

Abstract: A method of repairing a metallic member, such as a superalloy turbine blade, includes the step of preparing the blade by stripping the protective coatings from the blade. The blade is then pre-conditioned for welding by a first hot isostatic process. Once the blade conditioning sequence is complete, the blade is welded using a laser welding technique and by adding weld fillers to the weld area. After the welding step, the blade is sealed by a second hot isostatic process treatment performed at conditions similar to the first hot isostatic process. The blade is finally prepared for re-entry into service.
