p1b: list typical components in the system and describe their basic function and operation

Wastage Servo:

A servo is an automatic device that uses error-sensing feedback to correct the performance of a mechanism. The term correctly applies only to systems where the feedback or error-correction signals help control mechanical position or other parameters. For example? an automotive power window control is not a servomechanism? as there is no automatic feedback that controls position—the operator does this by observation. (Gunston? 1990) By contrast the car's cruise control uses closed loop feedback? which classifies it as a servomechanism.

CPU:

The Central Processing Unit (CPU) or processor is the portion of a computer system that carries out the instructions of a computer program? and is the primary element carrying out the computer's functions. (Gunston? 1990) This term has been in use in the computer industry at least since the early 1960s (Weik 2007). The form? design and implementation of CPUs have changed dramatically since the earliest examples? but their fundamental operation remains much the same.

RAM:

Random-access memory (usually known by its acronym? RAM) is a form of computer data storage. Today? it takes the form of integrated circuits that allow stored data to be accessed in any order (i.e.? at random). The word random thus refers to the fact that any piece of data can be returned in a constant time? regardless of its physical location and whether or not it is related to the previous piece of data. (Gunston? 1990)

ROM:

Read-only memory (usually known by its acronym? ROM) is a class of storage media used in computers and other electronic devices. Because data stored in ROM cannot be modified (at least not very quickly or easily)? it is mainly used to distribute firmware (software that is very closely tied to specific hardware? and unlikely to require frequent updates). (Gunston? 1990)

Prime power source:

Accordingly? it is an object of this invention to provide prime power and control for a device having deflectable canards thereon for use with standard gun-fired projectiles to provide terminal guidance to the projectile. (Gunston? 1990)

Generator:

An engine-generator is the combination of an electrical generator and an engine (prime mover) mounted together to form a single piece of equipment. This combination is also called an engine-generator set or a gen-set. In many contexts? the engine is taken for granted and the combined unit is simply called a generator. (Gunston? 1990)

P2a: describe the different types of fuel used in gas turbines

They accept most commercial fuels? such as gasoline? natural gas? propane? diesel? and kerosene as well as renewable fuels such as E85? biodiesel and biogas. (Gunston? 1990)

P2b: identify the colour codes and identification marking of these fuels

Natural Gas

Currently? there is no “standardized” color code for the plastic pipe industry. The purpose for this color code for solid wall pipe is to primarily identify the intended endues application of fuel gas (methane or propane) piping. This color code is only intended for solid ...
