@AirShaper
@AirShaper 4 жыл бұрын
Hi James, indeed, it's not an easy task!! Best to start with your payload & estimated weight requirements to obtain a required lift value. Keep in mind that when going from 2D to 3D, you loose quite a lot of lifting power due to the non-infinite wingspan. So be sure to run a full 3D sim at some point as well! And if the choice of airfoil is too complex, start with a common profile that you find on other drones (google will quickly show interesting references). The special profiles are for later on, once you've run prototype tests and/or need to upgrade your design later on.

It is a good video but i find selecting an airfoil as a first thing in the design process wrong. Airfoil selection can really be a late phase in design of a fixed wing vehicle. In drone design apart from cL/cD characterstics, coefficients of moment characteristics will matter more. If you are not in the last design phase, trying to optimize airfoil for optimum lift/drag without even having a planar and 3d profile yet will prove wrong. As an example, a thick or simple airfoil that still can get the jobe done will prove usefull in terms of manufacturing and extra size inside wing we can use for a lot of things.
@daniele.2944
@daniele.2944 Жыл бұрын
I agree with this. Also the 3d shape of the wing plays a significant role in the final aerodynamics. Also, you can't select an airfoil without knowing an estimated trim condition and flight Re. And you can't know that until you've performed high-level trade studies

Hi Viswak, there is a lot to be learned by just starting to build your own, using parts from hobbyking for example (if budget permits it). Setting up controllers and so on, will make you learn a lot! Apart from that, perhaps it could help you focus to decide on whether you want to go for vertical propeller drones, or fixed-wing like drones (in the latter case, you may want to focus more on general aviation theory). Good luck!

@AirShaper

I suggest you to browse airfoiltools.com to look around, look for efficient profiles for your specific Reynolds number. And keep in mind that when going from 2D to 3D you can lose a lot of lift due to the finite wingspan. So do check for correction factors for this befote you size the wing (you can find some in Joseph Katz's 'race car aerodynamics' book).

hi, im an engineering student and i m making a drone whose function is to carry an attachment that will throw a ball to a particular place at some height , i searched about drones , and i got to know that copters that lift more weight are difficult and too costlier to develop, so my q is can i opt for fixed wing to perform the same operation, whats your opinion?

Fixed wing drones can indeed carry more weight in some cases, but they need speed to have the wings generate lift. So it could be necessary to launch the drone using a catapult for example (this is quite common)

If you have a large runway, you may not need a catapult. The ground effect (wings generate more lift when close to the ground) will make take off easier. So it comes down to selecting an airfoil and a required velocity to get enough lift!

@@reeshadmuntasir5203 Initially, increasing angle of attack will increase lift without increasing drag much. So if you're looking for more downforce, that's a quick win. For for higher angles of attack, the increase in drag becomes significant and even the lift increase can reverse (the stall point).

Hi Wouter, my name is Angelo Conte and I'm an aerospace engineer who has working on the designing of propeller for a multirotor. I would like to ask you a question: suppose that I want to design a propeller (10 inches of diameter and 4 for pitch). What approach do you can suggest me to analyze the blade of propeller near the hub in hovering condition, where the Reynolds number is very very low and the beta angle is about 30 degrees? I thought to use xfoil with viscous analysis but in that condition the convergence of solution is never reached. Thank you in advance and my compliments for your videos. Great job. Ciao

Hi! Indeed in those conditions flow is quite tricky, as it's a very 3D flow: air doesn't just flow over the cross section of the airfoil, but also transversal to it. So an approximation with 2D simulations can be a bit tricky. If you're handy, I'd suggest to set up a cyclic 3D simulation, with either: - real moving geometry (sliding mesh) - virtual rotation (MRF - moving reference frame) - tangential velocity condition All of these can be done in OpenFOAM, if you like!
