The AEP session this week was on the topic of Engineering. The group learnt about the different types of engineer and the need for maths as an engineer! They looked at a piston engine and a jet engine and discussed the things needed for an engine to start and keep running. The boys were taught about intake, compression, combustion and exhaust or as those in the know refer to it - suck, squeeze, bang, blow!!!The group also looked at engine parts such as the crank shaft, cylinder and valves, and most importantly a spark plug. There were very informative videos on maintaining an aircraft and how an engine works.
