E477:🛗LIFT🏋🏻‍♀️Controversy🏫IISc🛩️Flight✈️&🚀Space🛰️Mech🔭: Bernoulli vs Newton vs Coandǎ vs Taha et al

🛗LIFTing🏋🏻‍♀️out🚠Controversies🤨: 6️⃣ Teams aptly adopting the punchy monikers "Pushpak Pioneers," "The wRight Wing," "Team Garuḍ," "ArchAngel Ate Well (oops🫤A12)," "The Turbulence Squad" & "Black Bird" attempt to explain how exactly a fixed-wing aircraft generates lift to balance its weight & beyond❣️ Should it be Bernoulli's Equation vs Newton's laws vs Coandǎ Effect vs Lanchester-vonKármán-Zhukovsky Circulation vs Kutta-Prandtl Viscosity vs Berdichevsky-Gonzalez-Taha-Peters-Ormiston Energy Functional⁉️ Well, the teams together end up showcasing implicitly that it shouldn't be a series of "versuses (sic)" but a series of "pluses," though in a non-superimposable sense‼️ This is a recording of the fourth class of the🇮🇳IISc🥼Course👨‍🎓: AE 201A (January-April 2026) 4:0 credits, wherein the consequential debate-style learning-cum-evaluation process is kickstarted: Part I of III: Flight Performance (FP): FP–T1: Principles of Lift Generation in Aircraft

Informal💬Description:
This 4️⃣-credit core course for🛩️Aerospace🚀Engineering🛰️(AE) MTech👩🏻‍💻students🧑🏽‍🎓is💯absolutely-holistic🌾in🪬its🌝approach🛣️&👼🏼nascently-introductory😇in its nature. It especially caters to those with🙅🏻‍♀️non-AE💺UG👩🏻‍🎓backgrounds, to facilitate them to self-realize & appreciate how the various other seemingly-disconnected🤔core📚courses that they have already credited in their first🥇semester beautifully😻merge🫱🏾‍🫲🏿together🤗in🤔a❄️wonderful🎶symphony, rendering the🤩amazing🪄magic🧚🏿of🛫heavier-than-air🌬️💨flight🛩️a🛬distinct👍🏼possibility🫡, not only to delectably😋savour👅for oneself, but also be amply🧐inspired to eventually & innovatively leverage existing & upcoming tools (including🤖AI/ML/robotics🦾) to design newer better performing &/or more efficient flying vehicles with additional &/or improved📈capabilities, accomplishing hitherto undreamt of tasks🐂for👥others👽too‼️

AE201A is therefore open to anyone, at any level of education, who is interested in grasping the🔡basics🔢of the physics of✈️flight, both🌎in🌍any🌏planetary🪐atmospheres☄️&/or🔭in🚀inter-planetary🌌space🛰️, employing mostly🏫high-school-level📐math & at the most∂bachelors-level🧮calculus❣️

Thanks for many of your kind compliments & enquiries on various platforms regarding this course. The live sessions are restricted to IISc students in-person only. However, as always with my classes, the 4K 120fps HDR recordings will be shared publicly on YouTube: https://shorturl.at/CajWD, well within 24 hours of each class.

It’s a sheer pleasure & rare privilege to share the little bit of knowledge & wisdom gained over many orbits, from so many gurus, back to my academic & spiritual siblings… amongst the many wonderful stalwarts who taught me at Margaret, SDA, St. Joseph’s, IIT-M, IISc & Georgia Tech, this one ☝️, in particular, is dedicated to my GOAT teacher: Late Prof S. Pradeep, AE, IISc, who taught us this very subject in two separate courses, or rather freaky roller coaster 🎢 joyrides 🥹 & whom we unfortunately ☠️ lost 😞 in an untimely manner & couldn’t so far find even half a replacement❣️
