Hi, I'm Aliya Burkit and I make videos on aerospace engineering!
Come to a Space Expo with me!
Last year I visited the Space Expo in the Netherlands and I wanted to share my experience with you all. I made this video in a different style, like a vlog. Please let me know in the comments if you like this type!
Oh, man.. it took me forever to edit this video.. over a year to be exact.. But the deadline of the new year finally pushed me to finish editing it and post it.

Introduction to Aerospace Engineering: Aerodynamics
If Reynolds numbers be the same model to full, as said at time 4:00, then explain NACA Note L57F12 as they address model concerns when predicting spin recoveries. Search Medium for “going beyond procedure - an open letter” perhaps adding “light twin spins” to the search, you’ll find a link to the Note and a tidbit from it further down while discussing Catherine Cavagnaro’s discussion regarding a model for a PA-28 spinning.
nice: if an aircraft in a turn can continuously maintain a 5G load, what should be done for that same aircraft to achieve the same lift (which compensated for five times the force of weight) in a straight line climb, i.e. that while climbing it has 5 times more lift than the force of weight
Sweet girl but for that NASA T-shirt. NASA equates with stupidity.
Love From India 🇮🇳
Naaaa its just the rocket equation
It was a wonderful video. Please keep making such types of videos It helps us a lot.❤👍
Thnks
The equal transit time hypothesis is circular reasoning. It says that a pressure differential causes lift. However, 'pressure differential' is a synonym for 'lift'. Lift does not cause lift. You can only get lift if you can deflect air. And you can't deflect air without getting lift. One is the action, the other, the reaction.
The shape of the airfoil does not cause lift. Rather, the shape determines the efficiency in the work of deflecting air. You can defect air inefficiently by having your flaps on while cruise, or by having them off while landing. However the shape is not the cause of the force, the deflection is.
The cause of lift is the acceleration of air downward. The is no other cause. You can not accelerate air downward without getting an upward force, nor can you have an upward force without accellerating air downward. A pressure differential does NOT cause lift. The bernulli effect does NOT cause lift. Rather, a pressure differential IS lift, caused by the deflection of air. The equal transit time hypothesis simply confuses the cause with the effect. The bernulli effect can help you understand HOW a force is transmitted to a wing surface, but does NOT explain the cause of the force.
So beautiful! 😮
This explanation is upside down.
Excellent!
This was totally not helpful! Now I want to go back to college and get my Aerospace degree. :P Seriously though, nice explanation. Short, simple, and clear.
A turbulent flow can be attached, and laminar flow can be separated. Your examples are misleading.
Bottom line = Air is accelerated downwards; airplane is accelerated upwards (against gravity). Everything else is detail.
You are so preety girl
1:20 NASA fairytale spacecrafts can't even leave their launchpads.
Thank You i needed this for a project worth 30 percent of my grade!
The tranistion point is incorrect in this video for a wing, 2100 to 4000 is for flow in a pipe For a wing, without inducing it by changing the AoA, it is about 500,000, eg the variable is velocity only. To induce it by stalling the wing the transition point is about 50,000. Using the transition value for a pipe and applying it to a wing is common mistake people make when dealing with Reynolds numbers.
It was still a very good explanation but thanks for clearing that up. I’ve been skirting around this for decades and she made it much clearer but I was a bit surprised that the figure was so low and I thought she might have omitted a zero or two.
Speed of sound is lesser than the speed i fell for your teachings 🫠
This was great!
Perfect, thanks!
Привет. Прочитал твой комментарий у Нургулана Сисембаева. Ты сейчас работаешь актером?
👏🏽👏🏽
Thank you so much. This video was very helpful to understand the thrust equation in rocket science 👍🤍..
3:48 The fact that the equal transit time assumption (it's so arbitrarily baseless, it's not even a theory in my opinion, only an assumption) is wrong is actually *not* proof that Bernoullis principle won't apply as the two ideas are unrelated. It's therefore not a limitation of Bernoullis principle. 4:52 Inverted flight is also not a limitation on Bernoullis principle, nor are symmetrical airfoils. In those cases, lift is generated by the AoA which lowers the forward stagnation point under the inverted wing, airspeed above the inverted wing will still be faster than airspeed below it. Bernoulli principle still explains the reduction of the static air pressure on the upper airstream hitting the inverted wing. It really isn't a limitation of the lift theory based on Bernoulli. 5:50 The "people or cars" example really hasn't anything to do with Bernoulli or lift. There is no directed outside pressure driving cars forwards against the will of their driver. If the faster cars would physically push the cars ahead through the narrowing by using brute force against their bumpers, those cars in the narrow part would not slow down (they would rather try to hit the gas because of the fear of getting rear-ended). The diffrence is that gas and water molecules are in contact with each other behaving therefore like a stream or a fluid, whereas pedestrians and cars behave like independent particles, they don't push each other around. At least as long as they're not engaging in POGO dancing. In the case of the wing of a spaceship flying well beyond the atmosphere, if that wing is occasionnally hit by particles, there would not be lift because there would be no "stream", only collisions which will obey Newtons law of impulse and force and counterforce (action-reaction). Because in that case we talk about particles and not about fluids or pressurized gases forming a stream and nobody in their right mind would try and use Bernoullis principle in order to predict the reaction of the wing to such a collision with a particle. Finally both Bernoulli and Newton need to be combined, Bernoulli can explain the lower pressure above the wing whereas Newton can explain the "ram air" effect creating higher pressure on the lower wing. Newton also explains why air masses are directed downwards behind the wing.
Thank you!, finally someone else said it: "The fact that the equal transit time assumption (it's so arbitrarily baseless, it's not even a theory in my opinion, only an assumption) is wrong is actually not proof that Bernoullis principle won't apply as the two ideas are unrelated. It's therefore not a limitation of Bernoullis principle."
big fan
hello aliya... these videos of u are very useful for me in my undergrad, can u continue the propulsion playlist please.
What's the minimum TWR for any rocket to lift off the ground and go up 100 meters???
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❤
Why do we need these Reynolds numbers? It's we must survive for another's missiles. That'll help us to protect from those missiles.
Tsialkovsky...........finally gets credit ...
If it wasnt for other countries, America wouldnt be where they are today. German scientists stopped WW2, not America
Thank you for this video, I was searching something that could explain "everything" about Aerodynamics (from Delft, MIT...) You were the first one who was able to teach everything, easily, so Thank you ^^
i'm stuck in mechanical engineering but i want to do aerospace engineering
Shouldn’t the Brit be credited over the Russian, on account of his developing the equation 93 years earlier?
Why do you say that we have to look for the lift coeff of the wing? Let say that the lift equal weight then you replace the number of the lift force by the weight of the aircraft in newton and if you know the surface of the wing and the speed, you will find the lift coeff...am i wrong ?
You're really trying your best, we appreciate that, I never took it for granted, because it's really helping at school. Thank you so much Aliyah 😊
Upload more videos N more lectures on aerospace.
I have learnt a lot here..im 16 I have learnt how to make a fluency better and some attitude and I love to learnt from a cute girl like you ❤😘love you
ISRO ❤🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳
Thankyou !! You have explained a major topic in a very simple and understandable manner this is the best video to understand the importance of Cl and Cd
Edition 3 of Anderson’s 3 is the best!
Bellissimo video insieme agli altri due. Veramente intetessante com una chiara edposizione per molti appassionati e studiosi dell volo spazisle. Spero che presto pubblichi molti altriv vifeo e sopratutto data la sua conoscienzs nella scienza spaziale possa introdurre un corso completo di Meccanica del volo.spaziale " che penso intetessera numerosi appassionati. Grazie e buon lavoro
Hi, thanks for the video. can you demonstrate how to incorporate the fluid mass in the equation? Will the mass of the fluid be inlet or outlet and which velocity do you use it with to get its momentum?
Please answer somebody the thrust on rocket is in which direction of rocket
Personally I dislike the use of two letters for variables. Anyone else agree or disagree??
Hii
Thank You Aliya for sharing this interesting expo. My institution plans to launch an aerospace engineering department and if you are willing to assist us please provide me your email address and let us have a connection.
hi, thank you for asking but my free time is limited due to work
