Foreign object detection for passenger-accessible stowage compartments

Systems and methods relating to foreign object detection with respect to passenger-accessible stowage compartments are provided. According to one example, sensor data is captured via a sensor subsystem that includes a sensor associated with each of a plurality of stowage compartments. For each of the stowage compartments, a baseline condition is identified in which foreign objects are absent from the stowage compartment. A foreign object is detected within a stowage compartment based on the sensor data received for the stowage compartment and the baseline condition identified for the stowage compartment. An audit of the stowage compartments is conducted, and based on the audit, an indication that the foreign object is detected within the stowage compartment is output. This indication may identify the stowage compartment containing the foreign object among the plurality of stowage compartments.

FIRE EXTINGUISHING SYSTEM AND METHOD

A fire extinguishing system includes a storage vessel and a fluidic oscillator. The storage vessel is configured to contain a fire extinguishing agent. The fluidic oscillator is configured to receive the fire extinguishing agent from the storage vessel, and discharge a continuous jet of the fire extinguishing agent while oscillating the jet back and forth through a sweep angle.

20210269139 · 2021-09-02 ·

An aircraft having a structure, a fuselage, a floor separating the fuselage in two, wherein the floor has openings, and, for each opening, a shut-off system having a flap hinged on the structure between a standby position in which the flap does not shut off the opening and a protective position in which the flap shuts off the opening, a return arrangement that urges the flap into the protective position and a retaining element that keeps the flap in the standby position and breaks when its temperature exceeds its melting point. Thus, when a high-temperature gas flow reaches the retaining element and this high temperature is higher than the melting point of the retaining element, the latter breaks and releases the flap, which shuts off the opening.

Engine nacelle heat exchanger

A nacelle for an engine includes an exterior housing a least partially surrounding the engine. The nacelle further includes a front portion proximate an engine face of the engine. The front portion of the nacelle defines an opening into an interior of the nacelle. The nacelle further includes a seal disposed proximate the opening. The seal is configured to selectively allow air into the interior of the nacelle. The nacelle further includes a heat exchanger disposed within the interior of the nacelle. The heat exchanger is configured to exchange heat between a fluid flowing within the heat exchanger and air at the interior of the nacelle.
