Reflection on Propulsion Demonstration - Steven_S10077211d

Head over to the room and then ordered to wear the ear masks. This was to ensure that we do not hurt our ears from sound generated by the engine. The engineer hit the buttons and turned it on. The attempt he made failed though. He said that it is alright as it because of the temperature of the engine. It needs a warm up. His second attempt was successful and indeed the engine was loud. I could hear it quite loudly even though i had my ear mask on.

He talked about how the air gets compressed and sucked into the engine. The air helps burning up the fuel in the combustion chamber. Soon thrust in generated by the hot gasses produced. i also noticed that as the revolution-per-minute increased the engine started to become louder. I also observed that the temperature increased during this time.

i believe that the plane is made in a way that it is able to cut so much sound from the engines. I wonder, if such small engines can make this much noise, how about those huge guys that are on the planes. Indeed amazing.
