Just found this channel yesterday, and what a gem it is. As a student currently learning aerodynamics I really appreciate your videos, they're very clear and easy to understand.
Personally I do prefer whiteboard for explaining anything..but for your videos both ways is great ...also you explained topics in the simplest way I appreciate a lot❤
YOU MAKE COMPLICATED TOPIC SO CLEAR AND MAKES IT VERY CLEAR TO UNDERSTAND THANK YOU SO MUCH FOR THAT AND I REQUEST YOU TO MAKE VEDIOS ON DIFFERENT TYPES OF DRAGS
I think these could be the answers. 1)L = W, T = D; I thought if T = D then there will be no net force and hence the aircraft can travel at uniform velocity 2)L = W, T > D; net forward force 3)L > W, T = D 4)L < W, T < D; Do we apply reverse thrust here? not sure though .. Did I go wrong anywhere? if yes, then pls do point it out. Thank you so much!
Great set of videos. As a software developer working in Aerospace I find your videos very helpful to understand concepts that I find in computer code. Thank You.
(1) Maintain straight level flight: L = W, T = D (Assume no acceleration or deceleration) → Straight flight means there is not net force in both vertical and horizontal directions. (2) Speed up: L = W, T > D (Assume no climbing) → To reach a positive acceleration, the net force of an aircrafts must greater than zero. This implies T-D > 0. (3) Increase height(Climb): L > W, T = D (Assume no acceleration or deceleration) → The raise of altitude is cause by vertical net force, thus the lift must greater than drag. (4) Brake(or decelerate) fast on a runway: L < W, T < D → To decelerate, the net force in horizontal direction must less than zero, which implies T - D < 0 or T < D.
Concerning the pool; I think the paper method is better than the whiteboard for the following reasons: 1. You are beautiful. And the way you talk, look, gesture, smile, park your hair etc sometimes attracts away from the content. It leaves one joggling between the content and the attraction. This makes comprehension a bit difficult and increases the frequency of rewinds in order to catch up. 2. Your movement across the whiteboard sometimes block content and makes it difficult to take notes or screenshots But with the paper method, your beauty distracts less and you movements blocks less and hence more comprehension and easier note taking. I trust this feedback helps a little bit. Thanks.
Hi Aliya. I don't know if I'm late but I prefer your explanations on the board :) I really appreciate your videos. I'm interested in airplanes and had a hard time understanding/visualizing why the pressure would be lower on top of a wing/airfoil. In my head it seemed more logic to have higher pressure on top since the velocity is higher and it sort of creates some high pressure/tension (skin pressure maybe?) but 8:22 to 8:37 made things a little bit more clear. Thank you! At 8:48 can you please explain to me why the airfoil tries to move in the direction of lower pressure? Is it like heat goes from hot to cold objects so the pressure also tends to go from high to low? That's one of the concepts I can't seem to understand
Yes, exactly, that's why in space movies if the door of the spaceship opens suddenly, the person flies away into space, because pressure inside the spaceship is higher than the pressure of the space (which is actually very close to vacuum). So the object goes into an area of lower pressure
I love your enthusiasm, and the passion you put in your videos (I subscribed), keep it up. The Explanation that you give here though is not correct. The "different length" explanation has been rejected long ago. Refer for example to this ruclips.net/video/edLnZgF9mUg/видео.html or ruclips.net/video/QKCK4lJLQHU/видео.html
on paper there is no echo while on the white board there is ... that is pretty much all the difference ... otherwise you are ding the same thing .... mind you being a cutie doesnt hurt either so I would say white board and hang the echo ;) . . (besides having the eyes STAY on the white board is easy with you IN the picture .. instead of just your hands) ... yeah Im old NOT dead ;)
hi, the incorrect lift theory you are describing here is called "Equal transit" theorem which is very wrong. here is the link to nasa webpage on that: www.grc.nasa.gov/www/k-12/airplane/wrong1.html
hy !!, Aliya :is it possible for someone like myself to dramatise your lectures, so as to sensitise the youth to appreciate the applacations of science principles in our daily lives?

I will try my best
1 L=W
2 TW
4 T
Thankyou so much. I'm passionate about aerospace and your style of teaching keeps me engaged
Thank you so much! 🙏😊

Answers look good to me

Definitely want to see more Aircraft Propulsion videos.
We're here to follow and support you. It's great project you have. Later you will have one of the popular science youtube channel.
Love this style, thanks for your demonstration. And pretty teacher by the way 😃
Thanks so much! 😊
I always am interested in learning about aeronautics though I m not into this field..a great knowledge to those interested..
Thanks!
Thank you so much. Cleared concepts well
Thank you for watching and glad it was helpful!

Aliya Burkit I see, thank you!
Glad it helped
Hi Aliya, great videos!. A question for you: Do you know what software is best for simulation of propeller airplanes? Not jet engine. Thanks
wonderful
Many thanks
❤❤❤❤❤❤❤❤❤❤
👌👍👊🏫thanks for teaching
My pleasure
@@AliyaBurkit Nice videos, probably watch them all soon 😁😁
Haha ok
I am really thanks to u mam❤❤
Thank you!
Incredible explanation!
Thank you! 🙏
Please get more videos on hydraulic and pneumatic and their meaning
Ok!
Thank you !!
Welcome! Nice youtube name you have! ;)
Please make a video on basic calculation of airfoil design and related thrust
Hi teacher !
Why the airflow is fast over the top of the wing ? I need explain. Thanks
Will you please make a video out jet engine and rocket engine
Yes that will not take just one video to explain everything 😂
Thanks 🙏🙏🙏 you teachers 👩🏫 So So Much 🌍✨💯👌👍💫
Thank you for watching!
I just found this videos on Thursday 2 july 2020
no problem))
what is the introduction of aerodynamics
my guess
straight level L = W
increase thrust to speedup
increase drag to brake
how to increase height...
Correct! To increase height (or altitude) we need L>W, simple
@@AliyaBurkit ohh i understand..your videos are super....
Thank you so much!
I want to know that total subjects in all semesters & all years in aerospace engineering
Can you please help me madam..?
Thank you! Video about it is coming soon
White board please
сен ең жақсы мұғалімсің
Рахмет
Are you a teacher by profession?
Not really, I am an engineer by profession, but working as a tutor now
White board would be better so I can understand physics and enjoy your beauty together 😉😉😄😄

I guess paper is better👍

Aliya I would like to seek some advice from you before declaring my major in aerospace. can I send you an email? whats the best way to seek advice?
Hello! Did you end up sending me an email? I will reply when I have time, hopefully this weekend
I dont have your email. Where can I send you an email? Please let me know. thank you so much for responding.
I think i mention it on my RUclips page, in the About section

White board was more Better
Thanks
Wrong explanation.
Watch video on RUclips "university of Michigan - how do planes fly"
Ok will check it
OK good job
