Aircraft Fire Protection Systems
To detect fires or overheat conditions, detectors are placed Fire Protection Systems in the various zones to be monitored. Fires are detected in reciprocating engine and small turboprop aircraft using one or more of the following:
1. Overheat detectors
2. Rate-of-temperature-rise detectors
3. Flame detectors
4. Observation by crewmembers
In addition to these methods, other types of detectors are Fire Protection Systems used in aircraft fire protection systems but are seldom used to detect engine fires. For example, smoke detectors are better suited to monitor areas where materials burn slowly Fire Protection Systems or smolder, such as cargo and baggage compartments.
Other types of detectors in this category include carbon monoxide detectors and chemical sampling equipment capable of detecting combustible mixtures that can lead to accumulations of explosive gases.
The complete aircraft fire protection systems of most large turbine-engine aircraft incorporate several of these different Fire Protection Systems detection methods.
Release valves are introduced on the compartments. A cartridge (squib) and frangible plate type valve are introduced in the outlet of the release valve gathering. Extraordinary congregations having solenoid-worked or physically worked seat-type valves are additionall accessible. Two kinds of cartridge circle discharge methods are utilized. Standard discharge type utilizes a slug driven by hazardous vitality to burst a divided conclusion plate.For high temperature or hermetically fixed units, a aircraft fire protection systems direct hazardous effect type cartridge is utilized that applies discontinuity effect to break a prestressed erosion safe steel stomach. Most compartments utilize ustomary metallic gasket seals that encourage renovation following wide scope of diagnostics is used to confirm the fire quencher specialist charge status. A straightforward visual sign measure is accessible, normally a helical bourdon-type marker that is vibration safe. measure switch outwardly demonstrates real holder pressure and furthermore gives an electrical sign if compartment pressure is lost, blocking the requirement for release pointers. A ground checkable stomach type low-pressure switch is generally
tilized on hermetically fixed holders. The Kidde framework has a temperature remunerated weight switch that tracks the compartment pressure varieties with temperatures by utilizing a hermetically fixed reference chamber.
