For decades, Vincent T. Padden, co-founder of Padden Design Engineering, has been advancing the state of the art in aerostructures and systems resulting in multiple US and European patent awards. These inventions have been utilized in the development of commercial aircraft programs resulting in significant weight and cost savings. Today, Vincent and the Padden Design Engineering team continues to create innovative designs including the breakthrough load transfer technology utilized in our Composite-Metal Hybrid components.

 

OUR LOAD TRANSFER TECHNOLOGY

Blending the benefits of hi-strength-to-weight carbon fibers with the robust bearing strength of titanium into one synergistic product results in ultra lightweight structural components for hi-performance vehicle applications. This technology is based around the principles of introducing and distributing applied loads into composite structural components efficiently. These hybrid parts are bonded structures capable of equivalent loading to their metal counterparts both in static strength and fatigue resistance including superior corrosion resistance. This breakthrough technology has opened the door for expanded applications for replacing metal structural and system components.

 

PATENTS

patent-sketch-8544361Composite Link Fitting

US Patent No. 8,544,361

This invention presents a composite link fitting which overcomes the inherent disadvantages of metallic link fittings such as higher weight and corrosion resistance. Control rod fittings, also known as “link fittings,” are extensively used in aerospace structures to transfer heavy and/or concentrated loads between two separate structures or portions of a structure. The composite link fitting uses a metallic bearing support bonded to a graphite core and outer band to efficiently transfer tension and compression loads into the composite link structure.

patent-sketch-5500272High Efficiency Load Transfer in Composite Structures (Graphite-Titanium Interleaf)

US Patent No. 5,500,272

This invention pertains to the attachment of fittings to composite panels for aerospace structures. The graphite-titanium interleaf is intended to reduce the number of plies which must be present in the vicinity of an installed metal fitting yet provide sufficient bearing area for a fastener attaching the fitting to the inner and outer laminates of a bonded panel. This is achieved by interleafing thin titanium sheets between graphite/epoxy plies. Reducing ply build-ups in panels minimize weight and complexity of manufacture.

patent-sketch-5224670Composite Focused Load Control Surface

US Patent No. 5,224,670

This invention relates to the manufacture of composite load bearing structures and, in particular, to the manufacture of an aircraft wing spoiler of honeycomb sandwich construction. The composite focused load control surface provides a co-cured one piece assembly in which the attachment fitting of the assembly’s control surface is caused to converge at the focus of the applied loads on the attachment fitting. This eliminates the need for direct shear attachment of the hinge/actuator drive fitting to the control surface because the shear load is carried as a component of the axial load at the fitting attachment surface.

patent-sketch-5390878Strain Isolator Assembly

US Patent No. 5,390,878

This invention pertains to a strain isolator assembly and, more particularly, to an isolator assembly for minimizing mechanical, thermal, and vibrationary strains between two interconnected structures. The strain isolator assembly allows deflections between joined structures due to heat and vibration overcoming the fatigue problem of rigidly connecting the structures in this type of environment. The strain isolator assembly has particular application in supporting a hot air blower tube within the cowling of a jet engine unit and the attaching of thermal protection panels on space vehicles.
