Abstract: A protection cap assembly for enclosing an end portion of a fastener which extends through a structure of an aircraft includes a cap member having a sidewall defining an opening and an interior space wherein the opening is aligned with the interior space for receiving the end portion of the fastener through the opening and into the interior space and an end surface for abutting the structure. The protection cap assembly further includes a projection secured to and which extends from the end surface of the sidewall of the cap member.

Abstract: A cap assembly for enclosing a metallic fastener which extends through a structure. The assembly includes a housing having an inner wall and an outer wall which extends about and is spaced apart from the inner wall defining a space positioned between the inner wall and outer wall. The assembly further includes a plunger member with a side wall portion secured to an end wall portion. The side wall portion of the plunger member has a thickness dimension smaller than a distance between the inner wall and the outer wall to position the sidewall portion of the plunger member within the space. With the side wall portion positioned within the space, the end wall portion is positioned in alignment with the inner wall and with an opening defined by and through the inner wall.

Abstract: A cap system for enclosing a metallic fastener assembly extending through a structure includes a first securement mechanism positioned about a periphery of a washer of the metallic fastener assembly wherein the first securement mechanism includes threads. The cap system further includes a cap member including a sidewall having an inner surface which defines a cavity dimensioned to receive the washer and defines a second securement mechanism complementary configured to engage the first securement mechanism positioned about the periphery of the washer. An end of the sidewall of the cap member defines an opening which provides the washer to have access into the cavity.

Abstract: A cap system for enclosing a metallic fastener assembly extending through a structure includes a first securement mechanism positioned about a periphery of a nut member of the metallic fastener assembly, wherein the first securement mechanism comprises threads which are interrupted as the threads extend about the periphery of the nut member and a cap member. The cap member includes a sidewall having an inner surface which defines a cavity dimensioned to receive the nut member and defines a second securement mechanism complementary configured to engage the first securement mechanism positioned about the periphery of the nut member and an end of the sidewall of the cap member defines an opening which provides the nut member to have access into the cavity.

Abstract: A method for certifying a design of a liquid container onboard a vehicle for manufacture of the liquid container is provided. The method includes generating a computer geometric model of the liquid container according to the design, and executable code to reproduce dynamics and operational parameters of the vehicle, with the dynamics of the vehicle including dynamics during a vehicle maneuver that is selectable from a database of vehicle dynamics for a plurality of vehicle maneuvers. The method includes executing a simulating application to perform a simulation of liquid sloshing in the liquid container onboard the vehicle is performed subject to the dynamics and operational parameters, and iterate the simulation to refine a prediction of loads and stresses on the liquid container from the simulation produced thereby. Locations within the liquid container more vulnerable to fatigue-risk are identified based on the prediction, and output for certification of the design.
