With a total of eight patents to his name, Szpunar's work has had a considerable impact on the design and functionality of modern aircraft components.

Latest Patents

Among his latest patents is the "Composite fan blade trailing edge reinforcement." This invention provides a composite airfoil that is particularly useful as a wide chord fan blade, which features a high degree of twist in large high bypass ratio turbofan engines. The composite airfoil includes a reinforced region that extends from its tip and a portion of its chord from the trailing edge. This region is covered by thin metallic sheathing that is bonded to the trailing edge surfaces of the blade, enhancing the structural integrity of the composite blade.

Another significant patent is the "Fan blade retainer." This invention involves a rotor blade retention assembly that includes a rotor blade with a dovetail mounted in a complementary axial dovetail groove in a rotor disk. The primary blade retainer secures the blade in the groove against axial movement in one direction, while a secondary blade retainer ensures that the blade remains in the groove after a predetermined travel in the first direction, in case the primary retainer fails.
