Could you please share the vsp model in this video?
Hi . When I run VSPAERO launch solver . Results are not shown and graph appears to be blank. Some options are grey . What should I do
Thanks for the tutorial, with that data, how to calculate the engine hp?
For piston aircraft - drag / 2.5 = average required h.p
Hello, thank you very much for this great video! It is really well done, could you please give your file of the A 400m?
If you need to visualize basic aerodynamics exporting STL on the fastest algorithm: Fluidx3D ruclips.net/video/Gd_MEHPecw0/видео.html
Great thanks? can you give sousce code&
We may not require any of these quantities, W, m, Iyy, S, MAC, Q, etc. as you are directly taking the values of Xa, Xu, Xw, Za, Zu, Zw, Ma, Mw, Mq, etc. These quantities are only required when you are using coefficients of the derivatives and converting them to the dimensional derivatives in this case your direct values.
You have chosen density rho = 1.225Kg/m^3 which is at sea level but your flying altitude is h = H = 23000*0.3048, which is incorrect. Density decreases with altitude.
I am solving for non-linear 6dof equations and I am getting all solutions straight lines for different initial conditions. Why? I checked with function (aircraft_EOM()) values it has different values then it is given out. Why is that they must be same. In a function I am solving 12 variables 12 non-linear equations for aircraft! Why I am getting the error could you please help me! You video is very helpful! Thank you for the video.
Hi mate, I would love to ask you some questions if you are still active on RUclips
@@universo_desconocido Thank you for your reply sir. The reason for the error is due to pitching angle goes near to 90degrees and cos term was on denominator. I implemented the solution by giving the condition, if theta = 90, change it to 89degrees or slightly more close to 90 degrees. Other than aircraft nonlinear equations of motion, I have developed the similar code for Airship nonlinear equations of motion. Thank you for your reply sir.
Hi again, I have a question: In VSP Aero, Mach number was set as 0. But after the graphs are plotted, we see that a Mach number is evaluated based on the altitude and flow velocity given. Why inserting M=0 in variables do not create a problem? (We only varied alpha and inserted 0 as M, but M did not stay as zero.)
M=0 is for the aircraft speed but the flow velocity can be from airspeed and not the aircraft speed. For example, if the wind gust is 100km/h, that is some flow velocity. It makes sense if the Mach is not equal to zero if the boundary conditions is not properly defined.
Hi, this was really helpful, thank you very much. I will make an opimization between wing volume and fuselage volume in order to reach some desired objectives. I'm considering to use OpenVSP for geometrical changes. What is the easiest way to change gepmetrical parameters automatically in OpenVSP? For example, let's say that the chord length and span will change such that Cl/Cd would be the greatest? Where can I reach you, if you are willing to help? Thank you so much in advance!
you're building something ?
Looks very impressive. What can you do with this model after you created it for OpenVSP? Can you derive meaningful flight characteristics from a simulation? I wonder if this is a viable solution to generating FlightGear flight models.
The Tinyhawk freestyle 2, is the reason that I am seriously into soldering......and getting more proficient all the time! I have had a couple of these drones and they are so much fun! I recently accidentally throttled way up, when my drone was upside down over a parking lot(black top)! Just snapped my frame in a couple of places. Already learning how close the 3 motor wire pads are to each other. If you can successfully solder the 7000 kv motors without bridging joints, you are just about on your way to soldering anything. I recently ordered the lollipop vtx antenna, and the small plug which can be soldered in place. I think that I may just separate the wire inside and solder the lollipop directly to the board, connecting the antenna to the active element!
I tried to take parasite drag of a wing alone and I couldn't able to obtain the values could you please help me
@avion dock where did you find the xalpha zalpha and malpha variables in the document? I could not find them.
It would be really helpful if u could touch more upon the results of the various graphs that are relevant to aircraft conceptual design... Like the one u said about elliptical curve and positive slope for Cl v Cd...
Thanks for the feedback! I will make another video about it.
Its such a superb little quad! With loads of room for progression upgrading and learning!
can you post the scripts in the description? They are not there.

Very usefull thanks!
How do you import the 3view image?
The scripts links are blank?
Very informative video! Do more such videos :)
I followed every step but for the fuselage is not showing up after comp analysis and vspaero analysis stops.
The software does crash if the geometry isn't defined properly. I mostly leave a small gap between the wing and fuselage and the other intersections to prevent this issue. Hope this helps.
