Latest Patents
One of Stoffer's latest patents is the Composite Vane. This invention involves metal darts that are captured in either bonded or riveted assembly with composite airfoil skins. The design features a thin fin extending rearward, which forms a hot air duct on either side of the fin. As hot compressor bleed air is diverted through the fin duct, heat is transferred to the dart's leading edge, effectively inhibiting ice buildup on the final coating that covers the airfoil. Additionally, the fin may contain ripples or other perturbances to enhance heat transfer as needed.
Another significant patent is the Fastener System. This invention describes a flush mounting fastener system for threadably attaching a threaded member to a plate or shell structure. It includes an internally threaded bushing with a flanged end for attachment to the housing, a plurality of circumferentially spaced crenelations, and an insert that engages the bushing. The design allows for a threaded member to be securely attached while accommodating non-coaxial threading axes.
