Aeronautic engineering (1 Viewer)

[jane1820]

I do STEM as an elective at my skl n have a yearly exam coming up
In the yearly exam i will be tested abt aeronautical engineering n i dont understand it at all
Like bernoullis law, angle of attack, weight = lift = drag = thrust and all that
basically i get it (not fully understand and or apply them) but i dont know how to answer questions like that

eg if the exam had a question w a plane asking why the plane wouldnt be able to fly, i wouldnt have a single clue why

my STEM teacher is also the engineering studies teacher n mentioned that this topic is covered in the stage 6 hsc modules n was wondering is anyone has notes on this?

well obviously u guys would take it into more depth but i just rlly need to understand it

n does anyone know which hsc past papers have this topic? Like the question numbers maybe i can do a “open book practise question”

idk plz any help is good bc im literally struggling w this specific topic so much (my teacher gave us classwork on this but i did those ages ago as hw using chatgpt as a guide - asking it to explain questions) n if im not exposed to more and new questions all the time then there isnt rlly any purpose in studying

edit: i just read the content for the aeronautical engineering hsc module and realised that i studied majority of the stuff covered, and as i look through the hsc past papers i’m familiar with the topics just as i said i’m not sure how to solve/understand

Too much words

At least u didnt reply w an ‘ok’ (ur probably gonna reply ‘ok’ or w a song to this one)

It sounds like you're looking for a way to better understand the principles of aeronautical engineering and how to apply them in your upcoming exam. Let's break down some of the key concepts, and I'll also guide you on how to approach exam questions related to these topics.

Key Concepts

1. Bernoulli's Principle:
   • Definition: This principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure. In aviation, this means that as air flows over the wings of an airplane, it moves faster over the curved top surface than the flatter bottom surface, creating lower pressure above the wing and higher pressure below it, resulting in lift.
   • Application: If asked why a plane wouldn't fly, you might say that if the wings were flat or if the airspeed was too low, the pressure differential wouldn't be sufficient to create lift.
2. Angle of Attack (AoA):
   • Definition: This is the angle between the chord line of the wing and the oncoming air. A higher angle of attack increases lift up to a point, but if it becomes too steep, it can lead to a stall.
   • Application: In an exam question, if a plane is stalling, you could explain that it may have exceeded the critical angle of attack, causing a loss of lift.
3. Forces Acting on an Aircraft:
   • Weight: The force of gravity pulling the aircraft down.
   • Lift: The upward force generated by the wings.
   • Thrust: The forward force produced by the engines.
   • Drag: The resistance force acting opposite to thrust.
   • Balance: For an aircraft to fly straight and level, thrust must equal drag, and lift must equal weight. If any of these forces are imbalanced, it can affect flight.
   • Application: If a question asks why a plane can’t maintain altitude, you might explain that if the weight exceeds the lift generated, the plane will descend.

Exam Strategies

• Understanding Questions: Practice interpreting questions by breaking them down into parts. Identify what is being asked and which principles apply.
• Open-Book Practice: Use your notes and textbooks to create practice questions based on past HSC papers. Focus on questions that require application of these principles.
• Study Resources:
  • Look for HSC past papers that specifically cover aerodynamics and forces in flight. Websites like NSW Education Standards Authority (NESA) can be helpful.
  • Search for study guides or resources on aeronautical engineering concepts on platforms like Khan Academy or educational YouTube channels.

Additional Resources

• HSC Past Papers: You can find past papers on the NESA website, and I recommend searching for papers from the Physics and Engineering Studies subjects, which may include aeronautical questions.
• Textbook Recommendations: Consider checking out textbooks specifically for HSC Physics and Engineering, as they often cover aeronautics in depth.

Hope this helps
