Abstract

The invention belongs to the field of aero-engines, and particularly relates to an aircraft engine compartment fire alarm detection system. Fire alarm detectors in a single engine compartment are divided into two groups, and the two fire alarm detectors arranged in parallel in each group are connected in series, so that the possibility of false alarm of a fire alarm detection system caused by false alarm faults of a single fire alarm detector is reduced, and the false alarm rate is reduced; the two groups of fire alarm detectors are connected in parallel in a fire alarm manner, so that missed alarms are reduced, and the reliability of the fire alarm detection system is improved. The fire alarm in each engine compartment can be displayed in the aviation cockpit through independent voice alarm and light alarm, and can be positioned to any engine compartment. Fault alarms of the four fire detectors in each engine compartment are connected in parallel, and faults of any fire detector can be alarmed and displayed in the engine compartment through lamplight. Fire alarm and fault information of each fire alarm detector is independently sent to the display control computer and the flight parameter system for recording.

Description

technical field [0001] The application belongs to the field of aero-engines, and in particular relates to a fire detection system for an aircraft engine compartment. Background technique [0002] The fire in the aircraft engine compartment seriously threatens flight safety. When a fire occurs in the engine compartment, it should be able to send a timely and reliable alarm to the crew. The engine compartment fire detection system should not only avoid missing alarms, but also reduce the false alarm rate. In the traditional single-circuit fire detection system, once a false alarm failure occurs in the fire detector, it is easy to cause the system to report a false fire alarm, increase the burden on the crew, and affect the flight mission. However, the dual-circuit fire detection system, which uses electromechanical computer for logical judgment, has higher requirements on the aircraft's own electromechanical management system. [0003] Therefore, it is desirable to have a te...
