This lecture was beyond commendable and it really has cleared all the doubts which I have been carrying since so many years. A well deserved thank you ma'am.
Just a heads up! What you've failed to mention is that vehicle needs to break the sound barrier first to deploy the ramjet or scram jet technology until then how do you make your vehicle airborne let alone to use the engine. Cost effectiveness of scramjet is frankly lies only on papers as we have to use one(or more) more engine or solid fuel to get the desired speed to initiate the natural compressor.
Sorry to say but I am an aerospace researcher and i can say jet engines never used in case of rockets. jet engines are for aircrafts. Rocket engine is far different from jet engines where no moving parts like compressor and turbine is used.U are showing a jet engine and sayion it is used for rockets. pleae correct
Ma'am How can Both Pressure and temperature in scramjet increased because we have read that temperature and pressure are inversely proportional.......????
Yes, that happens when system is open, .The baisc chemistry is moment temperature rises, high pressure is felt in the system, because of rising motion of molecules. The molecules collides with greater force in same space. However in open system, soon molecules dissipate and pressure is withdrawn.As happens on earth, air rises up when temperature is high. So pressure because low due to motions of air molecules upward. Not Directly because of temperature.Butt in closed system molecules are trapped with both high pressure and temperature, with nowhere to escape. For that you can imagine pressure cooker, waha temperature bhi high hota h and pressure bhi
First of all I don't agree with cost reason because as u said both ramjet and scram jet works only when aircraft reaches supersonic velocity ?then my question is firstly how it will reach that supersonic velocity ? actually for that we use turbo jet engine or turbo Prop fan engine(which consists of compressor and turbine) ...after reaching supersonic speed the turbo engine is shut down and ramjet engine is started .So if we are already using turbojet engine during lifting and during coming down how cost is affected ?the only plus point I think is probability of failure will be less because most of the time it will work in ramjet or scramjet engine.one for thing u missed very important concept of supersonic diffuser and supersonic nozzle because at supersonic speed nozzle acts as diffuser and diffuser acts as nozzle that is the thing which are making scientists to change all those shapes .......thank u
Please don't mind but you really lack the way to teach..it's difficult to correlate because you don't discuss important key point@forumias team.. please take this into consideration or else aspirant will loose credibility on your brand.

This lecture was beyond commendable and it really has cleared all the doubts which I have been carrying since so many years.
A well deserved thank you ma'am.
My God what an excellent explanation of such a typical topic in the most simplest way.
Thanks a lot forum IAS.🙏
Very amazing lecture mam... i thought it's difficult to learn but when see ur lecture ..really it's amazing thnku ma'am..
I watched many video on UA-cam but none cleared my doubt but your work is commendable
very nicely explained. But when do we use a RAMJET & when do we use a Scramjet?
Outstanding lecture... Thank you mam wholeheartedly!!!
This teacher is phenomenal
Ma'am thank you so much ... Your explanation is comprehensive and easy to understand
Thanks a lot ma'am . I visited UA-cam with lots of doubt in my head after watching your video 👌🙏👍
What a lucid explanation! Thank you ma'am.
Very well explained, good to see scramjet faculties on forums IAS!
Very well explained, being a mechanical engineer I can confirm.
Outstanding and Amazing level of Explaination Mam,
Hats off you
It's the best content ever found

Well delivered and efficiently explained 😀
thsnk u Mam well deep understand 🙏🙏🙏
Why isn't Prem Sorani Sir taking sufficient lectures these days along with Vishakha ma'am???....Plzz start taking lectures Prem sir!!
Amazing lecture ma'am

THanku very much Mam for lucid explanation
Thankyou so much ma'am , it was very helpful in understanding the concept, please do make such more videos on Utube🔖
Well explained ma'am ❤
beautifully expLained
Best explanation ever
Thanku mam ❤
THANK YOU NAMSTEY JAI HIND
Wow super explained 💯
Very well explained, thank you
Madam which fuel is used here ???
Was really informative. Thanks!

She is Explaining this in a wrong way.
I know I have worked on it
There is a problem
Temperature and pressure are directly proportional to each other, not inversely.
PV=nRT
P increases, T increases as well.
Thanks for sharing mam ❤️💯
thanks a lot 🙂
well taught mam
Excellent explanation mam
Ma'am इसमे to सिर्फ positive angle है.
इसके और कई nagative angle भी है जो सायद आप बताना भूल गई.

Madam if we don't reduce the kinatic energy means (speed) ...how we will increase the pressure and temperature of air????? For scamjet engine
awesome explanation
Thank you mam
Thank you mam❤
Madam, आपके बोलने का ढंग अच्छा है अगर थोड़ी सी बोलने की रफ्तार कम करेगीं तो थोड़ा समझने में और आपके बोलने का अंदाज अच्छा लगेगा 👍👍👍👍
Thanks mam ❤
Well explained
Nice lecture
super
maam
Mam thank u so much
Ma'am what is geostationary orbit
Thanks Mam
Lucky that I clicked on this video else I would have still be confused
Thanks, ma'am
YOU ARE THE BESSSSSSSSSSSSSSSSSSSSSTTTTTTT
Awesome
👌👌
Is this channel only for Hindi known students?
just wow.!!!
Current affairs k liye ek hi faculty h kya aap k pass???

She doesn't know a thing about aeroengines. I was laughing in most of the lecture. Please refer some good text book to clear your concept.
Bakwash hai madam
