Testing a Flying Duct
Просмотров 1,4 тыс.Год назад
DARcorporation recently built and hover-tested a foam ducted fan. Affectionately dubbed the "Flying Trash Can" for its looks by our team, this effort is being done to study control methods during a vertical transition. Ducted fans need to overcome an inherent pitching moment in cross-wind conditions, and this little test vehicle will help us refine our own control methods to mitigate that. Stay...

6. Solver Analysis and Convergence in FlightStream®
Hello sir thank you so much can I request something I'm a student in engineering University and I have a project about to modeling a fighter jet with Wto 25000lbs. Can you please upload a vid how to sizing a fighter jet with complete parts from weight to performance please thank you
Would this idea work on a cap equipped truck?
DragShield should be applicable. Please contact us at www.darcorp.com/contact-dar-corporation/#tab-992eb50acd3f927df71 to discuss this further. Thank you!
How can I get one?
What is the criteria for assigning the Source and sweep subdivisions? The Video unclearly states this under "chord-wize refinement ".
and what is the acceptable mesh for any simulation?
The source and sweep subdivisions are set in such a way to capture the pressure changes across the wing surface. The chord-wise direction (i.e. downstream) refinement is more dense so that each grid can represent the change in pressure across a small surface. Surface pressure changes a lot on the wing leading and trailing edges which means you need more grids (i.e. more source subdivisions). At the middle top surface of the wing, the spanwise pressure from root to tip does not change very much and that needs less sweep subdivisions to represent small changes in surface pressure.
Acceptable mesh is a case-by-case situation, dependent on your model. A useful rule of thumb is to set the mesh density enough to reflect the geometry shape and not over-mesh like traditional CFD approach. CFD-type very fine mesh only slows down FlightStream without contributing to results accuracy.
Do you have any academy free version
There is discount for students with valid identification but not free version of FlightStream. You can contact us at our website www.darcorp.com/contact-dar-corporation/ for more information.
The same nickname was given to the Goldeneye and T-Hawk :) Did you try modeling with DFDC? If so - how did things compare?
Excellent progress for a rapid prototype. Would love to see transition. Keep us posted!
Thank you. As would we 😂stay tuned!!
PFFF clearly fake (i can see the string buddy you aint foolin me 😎)
😂😂😉
Have you thought about designing a quadcopter with your design? Seems like it has potential thrust
What you guys do is truly fascinating!
Thank you Jtm!!!
This showed up in my feed, and has spiked my curiosity. What is its main purpose? Not trying be rude, genuinely can't think of an application for this. Thank you
Thanks for the question. For us, this simple vehicle serves as a testing platform to innovate control methods for our transitioning ducted vehicles.
I guess the foam around must be perfectly balanced to not cause any additional rotation due to asymmetric weight. Requires some skillful cutting. Haha
The foam is cut on the cnc, so we can get pretty precise in the features.
Looks great. You guys using Pixhawk and mission planner? Also, will be great to have some onboard cameras. Great job though. Good luck
Thanks!! Currently we're running our own inhouse control software using a NAVIO 2 sensor board. More videos in the future!
Looks sweet! Surprisingly stable.
Stable and ready for some outdoor testing!
s'prisingly L O U D ! did you measure efficiency?
She's got counter-rotating props which like to get noisy! Efficiency looks great even with everything in the flow.
Didn’t go so well???
Amazing UAV
Wish him rest in peace. His work will live with us. His book will remain as bible for thousand of engineers.
is the software affordable for student , or it just for big companies. i have been doing with pencil paper, MS excel and Catia. this software seems really advance and can save a lot of time.
What a great feat of engineering
I have a complete set of his design series books and a couple of others. Most are from a set owned by my previous boss, given to me when he retired, who couldn't help noticing how I pored over Roskam's books. I also attended many of his free online aviation history courses given through Kansas University for years.
His Aircraft Design books are a staple of every Aero-Engineering department.
Super ,♥️
Is building a model in advanced aircraft analysis surface 2.8 as easy as in OpenVSP? It looks like AAA surface 2.8 is an analysis software not a modelling software. Can an user import 3D model files from other 3D modeling software?
Advanced Aircraft Analysis (AAA) is a far more advanced software with 4.0 as its current version. Older versions like AAA 2.8 would pale in comparison with AAA 4.0 features. AAA is a comprehensive aircraft design program that gives users full authority over the entire preliminary design process. 3D models can be imported by not directly.

Cool! I'd buy one but I can't find them anywhere, guess I'll have to make one myself :)
Let me know if you find out were to buy a pice of absl that long. I would totally put this on the back of my shell..
@@chrslefty they make abs headliners for cars like 70's Camaro and Firebirds, others I'm sure too. That will be plenty big enough but it will probably be a bit expensive due to paying for the process of it being made to a certain shape. I'm sure I've seen plain large sheets on eBay
Volume ?
where can i get one
Hello DARcorporation, My name is Vidi, I'm from Indonesia, I have a question because i can't solved it from my teachers. I need to know how to Roskam Method use that Formula's (Torenbeek and GD) ?, and Why he used that formula?, Please answer me in my email muhnurvidianto123@gmail.com or reply this comment. Thanks before !
It looks awful
But does it look cool?
Great turtorial ! maybe you like mine too :)
