Abstract: A lock nut and tang washer mechanism preloads and locks components in a rotating environment. A drive system mechanism preloads and locks the device in a rotating environment and provides a double locking safety requirement needed in most aircraft for applications operating in an enclosed environment. The mechanism holds a required torque for the duration of the drive system operating life without the need for periodic visual inspections.

Abstract: Embodiments of an environmental barrier and seal include physical shields to protect against mechanical damage, labyrinth features to inhibit fluid/particle intrusion, impeller features, and a brush seal. Combinations of these features are presented in various embodiments, specific to particular operating conditions, to create an environmental barrier that protects primary carbon face seals and other shaft seals.

Abstract: An improved apparatus, system, and method for removing debris from lightweight components are disclosed. The improved apparatus can include an air mover, a cyclonic chamber in fluid communication with the air mover, an enclosure component operably attached with the cyclonic chamber, and a debris collection component in fluid communication with the cyclonic chamber. The lightweight components positioned inside the cyclonic chamber can be moved, rotated, or carried by cyclonic airflow, causing the lightweight components to hit against one another or against the sidewall, so as to separate the debris clung thereto.
