Question

Deliverables To be delivered as a single document to T313: 1. Every member of the team should produce at least one A4 page of drawings which clearly illustrate a group of components or views of your chosen artefact or process. Each student must draw different groups of components or views. Clear annotations on your drawings will help to clarifu detail to the person marking your work. All pages of drawings must be cleirly labelled with the name of the originator, and the originator,s student number. To avoid plagiarism DO NOT copy images from any source other than from your own investigations from your visit. 2. A report of no more than 10 pages (Arial 11 point or equivalent, single line spacing, normal margins) which addresses the points in task 2. Your report needs to be well itructured andlnay have thj following headings: Form and Function; Condition; Design; Aesthetics; Sustainability; etc. 3. A printed version of a Turnitin report for the written section. lnformation on this can be found in the Design folder on Blackboard.

Rolls Royce Merlin Engine -
Introduction – 
Rolls Royce Merlin engine is designed to work as one of the best aircraft engine to win the world war .this engine is also called as V-12 piston powered engines. Initially it was known as PV-12 means private venture & 12 cylinders. Merlin engine was started on 15th oct-1933
Type-
Liquid cooled, V-12 piston powered aero engine, it was first produced in UK by Rolls Royce limited for world war.
Main components-
1. Crank shaft- 
it converts the reciprocating motion in to rotary motion. It consists with counter weight. Crankshaft is usually made by forging process.Hardening process is also carried out in order to produce the hard outer Surface.
2. V-12 Engine- 
V-12 engine is main component used in Rolls Royce merlin engine in which there are 12 cylinders arranged in V-form usually at 60 degree angle. It runs smoothly the system without any vibrations.There are 12 cylinders attached with crank-case in two rows by 6 cylinders in each row.
3. Cylinders- 
12 cylinders are used over here with different heads & skirts. Inlet valves are fitted and these inlet valves are made of cast iron. Exhaust valves guides are also provided made of phosphor bronze. Piston moves in these cylinders in to and fro way.
4. Pistons- 
Each cylinder has separate piston that moves in cylinder and produces pressure in order to rotate the crankshaft. There are some piston rings are provided. it transfer force of expanding gases  to crankshaft with the help of piston rod or connection rod .
5. Crankcase- 
Crank case is known as housing for crank-shaft, connecting rods and other parts of engine, crank case is usually made of aluminum for aircraft engines and process that used to make this is casting. In a crank case there are some arrangement to connect some key parts like crank shaft bearing, carburetor floor, space for fitting of cylinder, water jacket, Rocker arm struts.
6. Super charger- 
Super charger is key part of Rolls Royce engine, it increase the pressure (above atmospheric) of air entering to system. 2 stage supercharger is used in this engine ,in 2 stage super charge there will be two impeller used for compressing .one impeller will be smaller than other  impeller.
7. It is driven mechanically by belt drive or chain drive with crankshaft of engine.
8. Coolant outlets- it is attached to a coolant extraction port in cooling system used in this engine.
9. Vacuum pump inlet
10. Vacuum pump return
11. De-icing connection to propeller
12. Engine mounting feet
13. Oil pressure gauge connection- To know the pressure usually measured in Psi or Kg/cm2
14. Oil thermometer gauge connection – To know the temperature so that if temperature increases beyond the setting limit then interlocking may be used to maintain the healthiness of system.
15. Coolant inlet to cylinder 
16. Dowty pump drain
17. Oil inlet
18. Oil outlet
19. Coolant pump outlet
20. Starter motor terminal
21. Wheel case breather unit
22. Supercharger bearing vent
23. Magneto earthling connection
24. Magneto Booster coil connection 
25. Throttle control levers
26. Constant speed propeller governor unit
27. Slow running cut-off lever
28. Boost gauge connection
29. Cabin heater connection
30. Haywood air compressor outlet
31. Engine starting handle
32. Fire extinguishing system inlet
33. I.A.E pump delivery 
34.
