'ith deep sense of gratitude! first and foremost e,press my profound

than"s to Mr.Ra#%* 9$,ar A#%)&r% chief -anager ALH for giingme this opportunity to do my summer training in .nstrument department ofHindustan Aeronautics Limited! Luc"now during the summer session 2/0/#

Being renowned company of .ndia a$road! it gae me theopportunity to learn the wor" carried out here! got a glimpse of new

enironment hard wor" of industrial unit#

Mr. A. 9. /ar,a Chief &ngineer#of ALH . was posted under his

guidance# He was ery helpful during my training#

PrefacePreface

Training has misinterpreted $y most of us as a platform for

pro3ect performation# .ndustrial training in true sense has $een included in

curriculum to ma"e the student well ersed with the technical procedure of

arious industries! the $asic criteria for management of arious resources in

a company or industry#

The educational institution sole aim $y industrial training is toimproe the technical "nowledge and to hae a hand on e,perienced to ma"e

them realistic in thin"ing! to understand the procedure for manufacturing

"eeping mind the minute detail which will $enefit the customer li"e no

learning is proper without implementation#

octors! Lawyers! hotel management student surely hold a upper

hand# .ts $ecause right from the second year of their graduation the are made

to face the world and their pro$lems with a tender mind# .n due course of

time slowly $ut steadily they! deelop a competitie attitude and hae a

definite plan and aim as they complete their graduation#

Unli"e the pitia$le engineers li"e us who are completely isolated

from industry# Therefore their should $e industry institutions made

compulsory for eery engineering institutes#

INTRODUTION"

C -aster Bo, is a part of dc power generation and distri$ution system for

re:engine Cheetah Helicopter# .t is designed for use with an independentstarterFgenerator mounted on the engine accessories gear$o,! and isinterfaced with GCU! $attery! and e,ternal power source and control panelof C power generator to the loads through its main $us# .n the eent offailure of starterFgenerator! the dc master $o, will actiated the $atterycontactor! through which the on:$oard single $attery (6i:Cd / Ah) will getconnected to the main $us supply power to the emergency loads# C&,ternal ower 5eceptacles (&5) is proided at the port side of theHelicopter with &C in C master $o, to supply the dc power from Groundower Unit (GU)#

FUNCTIONAL DE/CRIPTION

C -aster Bo, distri$utes the complete dc power generation# .t contains themain $us through which dc power is directed to the oerhead panel

through circuit $rea"ers for dc power distri$ution#

uring normal operation! the total dc power from starterFgenerator is$rought to the main $us through 6ormally pen (6##) contactor! which iscontrolled $y GCU#

.n case of failure of starterFgenerator! the dc power will $e aaila$lefrom a single on:$oard internal $attery through a normally closed $atterycontactor# roision has $een made for receiing the dc e,ternal powerduring ground operation through an e,ternal power receptacle# The e,ternal

dc power supply is transferred to main $us through 6## contactor! which isswitched on $y &,ternal ower Card (&C)# The &C switches the e,ternal

power contactor 6 only if the applied oltage is with in specified limit of correct polarity and therefore protects the dc system from oer:oltageconditions# As long as e,ternal power is connected to the Helicopter(&,ternal ower Contactor is closed)! $attery should remain disconnected#

There may $e multiple failure modes for each functioning# esign has $eenfound to meet the $asic criterion for e,ternal system* :

a) 7ingle fault at a time should not affect the normal flight# Thishas $een designed as -.65 failure# This may also $ecalled as C6T5LL& %AULT! which may $e corrected

$y appropriate design safety deice or specialautomaticFmanual procedure# Hence! one fault at a timeshould only lead to -.65 failure#

$) ou$le fault occurring simultaneously should not lead to anemergency situation and may $e counteracted $y emergencyaction# Hence! two faults simultaneously should only lead to-A?5 failure#

c) Triple faults occurring simultaneously may lead to anemergency situation# This may also re@uire .LT7immediate action for emergency condition# This type of faulthas $een called as C5.T.CAL failure#
