How feko cater for blade rotation effect?Like for Helicopter, Propeller or Inlets with blade?
Hi @ben,
What effects are you trying to analyse? The propeller position could affect the radiation patterns of antennas, currents flowing on the surface, coupling between cable bundles in different sections of the vehicle or coupling between antennas on the vehicle. Depending on your investigation, different answers might apply.
Without really understanding what you are doing, I can nevertheless maybe give the following hints:
If you are interested in looking at how the modulation effects of the spinning blade, you might have to contact the FEKO support team for more guidance.
Let me know if this helps; otherwise you can maybe provide more information about what you are trying to do so that I can give a more targeted answer.
Good luck! :-)
Thankyou for your reply. I am simulating radar cross section of helicopter and also observing radiation pattern of antennas.I want to simulate rotation effect in both and I want to know how accurate it give the results?
You can maybe take a look at the Examples Guide ( B-1 Antenna coupling on an electrically large object) for an example of simulating a helicopter type problem. This should give you some ideas of which solvers are applicable.
I want to know how accurate it give the results?
Well... that depends. FEKO can give you very accurate results if the model is configured appropriately. You can maybe find some more explanations on the Resource Library (https://altairhyperworks.com/ResourceLibrary.aspx?keywords=radar+cross+section&altair_products=FEKO) and examples on the HyperWorks Insider website (https://insider.altairhyperworks.com/?s=radar+cross+section).
A study that compares mathematically known RCS values with simulation data should give you more of an idea with respect to accuracy:

The short answer is: You can get very accurate results for RCS and antenna patterns and the rotation effect can be included (see my previous comment for thoughts on that).
