Helicopter Flight: What is the reason for decrease in Induced drag with ...
1 As per the figure the induced drag will decrease only if the AoA of the blade is decreased — But in the forward flight, cyclic input increases and decreases the AoA throughout the blade rotation cycle. …
aerodynamics - Induced drag - where does it actually arise from ...
Aug 16, 2022 · Several explanations about induced drag exist. Even if these explanations are simple and appealing (and not necessarily correct) they lack any connection to how actually the concept of …
aerodynamics - Does the downwash created by induced drag increase …
Apr 10, 2015 · Induced drag is due to vortices at the wing tips and they also create downwash. So according to the above theory induced drag should also increase lift. But, the books say that induced …
principles of flight - Induced drag vs parasite drag understanding ...
Feb 5, 2023 · The actual distinction between induced drag and parasite drag is simply a matter of definition. Parasite drag is that drag that the aircraft would experience at zero Lift, - at that AOA …
aerodynamics - Is induced drag essentially nothing more than a …
May 29, 2016 · Induced drag is different as it decreases with speed, but so does the cross-section of the object striking the air and creating the drag. I wonder: if a specific angle of attack were forced to …
What is the formula for induced drag? - Aviation Stack Exchange
The problem i'm having is that I want to make a graph for the induced drag. But whenever i use the given formula the drag increases with a higher speed instead of decreases since lift is also …
aerodynamics - Explaing lift tilt back in induce drag pictures ...
Nov 17, 2022 · This is usual induced drag diagram. What is black vector in diagram below? If it is lift you cant decompose lift in lift(L in diagram) and induced drag (Di), this you can do only if this is resultant
Explained intuitively, why does aspect ratio affect induced drag?
Feb 5, 2021 · This means that for lift to be generated, downwash must exist, therefore induced drag is an inseparable side-effect of generating lift. Let's imagine 2 theoretical wings, both of which have the …
aircraft design - What is the relation between drag and weight ...
Apr 6, 2018 · 1 It is hard to say what the ratio would be exactly. Total drag consists of parasite drag and induced drag. The influence of angle of attack to parasite drag would depend largely on the aircraft …
aerodynamics - How is the induced drag calculated for a wing with ...
How is the induced drag calculated for a wing with elliptical planform? The elliptical, untwisted wing has the same angle of attack and the same lift coefficient over span, and produces the desired constant …
