REASONS FOR CHOOSING THIS

PROJECT Low cost.

found this project more useful for campus training

purpose.

Construction is much easier than others. Materials and components are available in local

markets.

Students are familiar with this project.

Aim and Objectives

The main objective of this project is to use

as practical and educational purpose.

student can gets clear conceptual view of

the operation of boosted flight control

system.

This project must help the lecturer to give

a visual concept to make understand for

students.

AIRCRAFT FIRE DETECTION SYSTEM

To detect fires or overheat conditions, detectors are

placed 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

AIRCRAFT FIRE DETECTION SYSTEMThe complete aircraft fire protection systems of most large

turbine-engine aircraft incorporate several of these differentdetection methods.

1. Rate-of-temperature-rise detectors

2. Radiation sensing detectors

3. Smoke detectors4. Overheat detectors

5. Carbon monoxide detectors

6. Combustible mixture detectors

7. Optical detectors

8. Observation of crew or passengers

The types of detectors most commonly used for fast detection

of fires are the rate-of-rise, optical sensor, pneumatic loop,

and electric resistance systems.

AIRCRAFT FIRE DETECTION SYSTEMOur fire alarm circuit based ona (Thermal switch)for sensing the fire. The alarm works by

sensing the fire. The circuit produces an audible alarm when the fire breaks out with smoke.

The type most commonly used is a switch, the contacts of which are actuated by the

differential expansion of dissimilar metals. The thermal switch is a unit type and called

a spot or point detector.

BATTERY 9 VOLT

An electric batteryis a device consisting of one ormore electrochemical cellsthat convert stored

chemical energyinto electrical energy. Each battery consists

of a negative electrode material, a positive electrode material,

an electrolyte that allows ions to move between the

electrodes, and terminals that allow current to flow out of the

battery to perform work.

LIGHT EMITTING DIODE

Alight-emitting diode(LED) is a semiconductorlight source.[7]LEDs are used asindicator lamps in many devices and are increasingly used for general lighting.

When a light-emitting diode is switched on, electronsare able to recombine

with holeswithin the device, releasing energy in the form of photons. This

effect is calledelectroluminescence, and the color of the light (correspondingto the energy of the photon) is determined by the energy band gapof the

semiconductor.
