Abstract: A fire suppression system includes a feed port and a channel to couple the feed port to an actuation chamber. A solenoid valve controllably blocks a connection between the feed port and the channel. Pressure from the feed port builds up in the actuation chamber based on the solenoid valve unblocking the connection. A piston is in communication with the actuation chamber. The system also includes an inlet port closed off by a disc. The piston travels through the inlet port and burst the disc based on the pressure in the actuation chamber. An outlet port is coupled to the inlet port.

Abstract: A safety assembly provided with an automatic fire extinguisher system includes an engagement member, a blocking member, and an extension member. The engagement member is slidably received within an outlet port of a valve housing. A blocking member having a first blocking member portion and a second blocking member portion is at least partially received within a cavity defined by the valve housing. The extension member extends between the engagement member and the blocking member.

Abstract: A fire extinguishing composition includes a propellant, a dry chemical fire extinguishing agent and an anti-decomposition agent.

Abstract: Overheat and fire detection for aircraft systems includes an optical controller and a fiber optic loop extending from the optical controller. The fiber optic loop extends through one or more zones of the aircraft. An optical signal is transmitted through the fiber optic loop from the optical controller and is also received back at the optical controller. The optical controller analyzes the optical signal to determine the temperature, strain, or both experienced within the zones.

Abstract: A valve assembly includes a valve with a valve body and chamber. A poppet with a stem and piston is slidably engaged inside the valve body. A poppet release mechanism is included for releasing the poppet from a closed position. A mechanism cover is attached to the valve body. A safety mechanism with a pin, spring, and lever is included for preventing the poppet from moving into a fully open position. A first end of the pin extends into the chamber into a pathway of the poppet and a second end of the pin extends into the valve body of the valve. The spring is positioned between and in contact with the pin and the mechanism cover to bias the pin toward the poppet. A first end of the lever is pivotably attached to the pin and a second end of the lever extends out from the valve body.

Abstract: A method of operating safety mechanism includes extending a safety pin to block a poppet from opening a flow path from a pressure vessel in the event of the pressure vessel being unmounted from a bracket or in the event of the bracket being unmounted from a support structure. The method includes retracting the safety pin to allow free movement of the poppet for opening the flow path only in the event of the pressure vessel being mounted to the bracket and the bracket being mounted to a support structure.

Abstract: A valve arrangement includes a housing with an outlet and an inlet and having a poppet. The poppet has a stem and is movable within the housing along a movement axis between an open position and a closed position. The inlet is isolated from the outlet when the poppet is in the closed position. The inlet is in fluid communication with the outlet when the poppet is in the open position. The stem is inverted relative to the housing such that at least a portion of the poppet stem is disposed in the inlet when the poppet is in the open position.
