Sem.1 Week 11: Voice Over Script

I received an email during mid week of week 10 by a member of the group asking if I could type up a script for a Voice Over which will be included in the presentational Video.

The topics to be covered were:

-Why the MK 14 Griffon Engine was Designed and Developed.

-How the Griffon compares with it's smaller predecessor the Merlin Engine.

-Why is the Griffon, being a V12 engine, better than a Radial engine?


I was able to find a considerable amount of information for comparing the Griffon and Merlin engines and in the Griffon engine'd Design and development but very little on why the V12 Griffon is better than a radial engine.

I produced the script after resaerching about all three engines on the below 3 sites and by asking a local expert about the engines.

Griffon

Merlin

Radial

From this research I was able to produce the below Script:

Person 1:

Hello. This is a virtual representation of an MK 14 Griffon engine.

The ‘Griffon’ engine was originally designed and developed by Rolls-Royce to be interchangeable with its predecessor the ‘Merlin’ engine, and was to be used for low altitude naval aircraft such as the Fairey Firefly. However, during its development, it was suggested that the ‘Griffon’ engine would be adapted to fit in a Spitfire. This suggestion was made by Supermarine’s chief design engineer Joe Smith in 1940.
Later on in the engine’s development however, work on the ‘Griffon’ engine was halted to move focus and concentration to the smaller 27 L ‘Merlin’ which had already surpassed with the early ‘Griffon’ engine design. This was made so, on the order of Lord Beaver Brook, the Minister of Aircraft Production.

The Griffon, when compared with the designs of its earlier predecessors, had several advancements in its design. Physically it was only slightly larger than the Merlin in spite of the Griffon’s larger fuel capacity of 37 litres to the Merlin’s 27. The other main difference was the Griffon’s camshaft and magneto drives were built into the propeller reduction gears at the front of the engine rather than being driven from the back of the camshaft.

This, in turn, allowed the overall length of the engine to be reduced which proved to make the Griffon engine more reliable and efficient, not only by reducing the engine’s length but also due to the idea of fitting the Griffon with an internal oil flow system which contributed to the lubrication of the engine and required less maintenance compared to the Merlin’s external oil lines which required much more maintenance and were prone to leakage.
