What we want:
We need to prepare a final report from 40 to 50 pages for our final project. We want 4 reports each
report is 40 to 50 pages as mentioned. The reports may not look so similar and you make some
changes and modifications based on the layout of the report, adding or removing some sub topics.
The theory and main idea should be the same but the way of ordering and look of the report should
be different. You can communicate with me for any kind of clarification.
The report shouldcoverthe requirementsas shown below.
1- Introduction:
It should coverISRbrief competitionhistory,rulesof participation,categoriesof racingparticipants
and racesrecords andresults.
2- Paragraph Body:
Contains the followingmainpartsandyoucouldadd as per requiredornecessaryaccordingtothe
ISR Final reportsattached:
- Bodydesigningandmodification.
- Hull designing.
- TestsPerformed.
- Hydrodynamicanalysis.
- Assume calculationssimilartothe reportsand we will putournumbers.
- Internal partsincludingmechanical parts.
- Control system.
- Buoyancyideaandpop up buoyancy.
- Propulsionsystem.
- Safetysystem.
3- Conclusion:
- References.
- LessonLearned.
- Future conceptfor modification.
 Body modificationand design:
Bodywas designinautocad and the designwastakingfromTUNA FISH,we try to have the designof the
Tuna because itconsidersone of the fastestfish.
3 bodieswere made fromfiberglass.
Body1:
Made incollege andfaileddue toshortage inmaterial andmachineswhichuse forfiberglassandcost
was high,butwe got an experience inmaterialselectionandmethodof bodydesigning.
Body2:

2. Made incontractor workshopandit faileddue tothicknessof bodyandthe dimensionwasnotcorrect.
Body3:
Was perfectandit succeeding?
Body dimension:3meter, diameterfromcenter90cm, H from center90cm, bodythickness4mm.
 Internal part includingmechanical parts and control:
Internal partfor submarine wascontaining the followingparts:
 Gear: Gear ratio1 to 7 made fromSS connecteddirectbypedal andshaft,the gear wasmade
inwork shop.
 Driveshaft:Shaftdiameter10mmand L 50 cm made of SS.
 Propeller:Propellermade fromtowingSSwithangle foreachwing30 degree.
 Pedal:Pedal wasconnecteddirecttogearand itlooklike bicycle pedal.
 Joystick:Joysticklinkedwithstainsteel cables,cable one fordirectionupanddownand cable 2
for liftandright,eachcable have connectedroadto wingof submarine.
 Fins:Connectedbythe cablesof the joysticktodirectthe submarine directionup,down,right,
and left.

the submarine will be one oxygencylinderforpilotwith250bar pressure.
Buoyancyof submarine wascontrolledby thermocollmaterial duringtestunderwater.The required
numberof thermocoll sheetwasaddeduntil we reachtothe rightlevel.
Testone
Was conductedinswimmingpool for3 hoursand we face problemwithbouncyof the submarine,but
we testthe submarine andwe reachto rightlevel of bouncy.
The speedof submarine wasbetween5to 6 km/hand duto lengthof the pool we couldn’tincrease the
speedof it.
We testanotherpropellerwithbigsize butitfailedbecausethe lode wasveryhighondiversince the

3. Testtwo
We plannedthe testtohave official videoandpicture topresentitforcollege anditwas successful run
for the submarine.
