Patent number: 11565454Abstract: An apparatus for shaping an extrudable material comprises a sleeve, comprising a first sleeve end, a sleeve inlet at the first sleeve end, a second sleeve end, opposite the first sleeve end, and a sleeve outlet at the second sleeve end. The extrudable material enters the sleeve through the sleeve inlet and exits the sleeve through the sleeve outlet. The apparatus further comprises an actuation mechanism, selectively operable to change at least one of a size or a shape of the sleeve outlet. The sleeve is sufficiently flexible to enable the actuation mechanism to change at least one of the size or the shape of the sleeve outlet. The sleeve is insufficiently stretchable to enable the actuation mechanism to stretch the sleeve.Type: GrantFiled: September 2, 2020Date of Patent: January 31, 2023Assignee: The Boeing CompanyInventors: Michael Patrick Kozar, Mark S.

Patent number: 11008114Abstract: Various techniques are provided for an expandable energy absorbing fluid bladder. In one example, the fluid bladder includes a primary portion and a secondary portion. The secondary portion can be configured to expand or increase in volume when the fluid bladder is subjected to a pulse greater than a threshold pulse. Expansion of the secondary portion can allow fluid or additional fluid to flow into the secondary portion and thus decrease a peak pulse and, thus, avoid rupture of the fluid bladder.Type: GrantFiled: September 7, 2017Date of Patent: May 18, 2021Assignee: The Boeing CompanyInventors: Michael Patrick Kozar, Mark S.

Patent number: 10974841Abstract: A reinforced composite article includes a first ply, a second ply, and a third ply. A first interface material is between the first ply and the second ply. A second interface material is between the second ply and the third ply. A designated pattern of material property variation, geometric structure variation, spatial variation, or combinations thereof is distributed to selected locations identified in the first interface material or distributed between selected locations identified in the first interface material compared to the second interface material. The pattern is sufficient to measurably vary adhesion, toughness, strength, modulus, or combinations thereof. The article allows distribution of a load across the pattern when the first, second, and third plies receive a force from kinetic energy above a separation threshold by partially delaminating the first ply from the second ply, the second ply from the third ply, or both.Type: GrantFiled: February 26, 2018Date of Patent: April 13, 2021Assignee: THE BOEING COMPANYInventors: Mark S.
