This so called PPT for propulsion study for Shenyang Aerospace University. This PPT right protected by Dr. divinder K. Yadav. Its using in SAU by Lale. For all students of Aeronautical Engineering must memorize each & every words from this PPT. If you miss a single words you must fail in the Exam. Remember there is no chance to be creative or use sense you just need to use the power of memorizing.

5. Fire Detection Systems
Thermal switch system:
It uses a bimetallic
thermostat switch or spot
detector.

6. Fire Detection Systems
Thermocouple system:
Works on rate of temperature rise.
Does not give warning when an engine slowly overheats.

7. Continuous - loop detector system
In case of fire, the core resistance drops and
current flows between the signal wires and the
ground, energising the alarm system

Types of extinguishing systems
High Rate of Discharge (HRD) System:
Provide high discharge rate through high pressurisation, short feed
lines, large discharge valves and outlets. Extinguishing agent is
released into the zone in one second or less.
Conventional System
System is designed around a cylinder that stores the CO2 under
pressure and a remote control valve assembly in the cockpit to
distribute the extinguishing agent to the engine.
