It's not mentioned in the article, but I wonder if part of this is about stealth. I imagine the moving control planes might create additional cross section vs not having them?
- londons_explore 3y agoIt sounds like this option could let you make the wings and tail of the plane metal-free, which is good for hiding from radar
- Terr_ 3y ago> the wings and tail of the plane metal-free At some point that's like trying to make someone invisible by making their skin--and only their skin--transparent. It'll backfire when all the twisty complicated still-important stuff on the inside stands out even more.
- superb_dev 3y agoWhat is the resolution of modern radar? The important core might not be big enough to see
- Vecr 3y agoIt's not about resolution, you can see stars easily that your eyes can't resolve as a disk. It's about magnitude.
- c22 3y agoWith this scheme it seems you could concentrate all the twisty complicated stuff to a small area in the body of the plane and use rubber hoses to deliver the air to the control surfaces.
- Terr_ 3y agoInternal space of wings is often used for storing fuel. I'm not sure if there are any studies on how well modern radar could detect sloshy blobs of kerosene flying through the sky. (Inside totally radar-transparent containers.)
- ArnoVW 3y agoI am not an expert by any means, but my understanding is that stealth generally does not work by rending surfaces transparent, but by absorbing the energy or reflecting it in a very, very focused way (away from the origin). If you send a radar beam and nothing comes back, for the radar operator that means "no plane".
- aredox 3y agoStealth and aerodynamics. The idea isn't novel, but the degree of detail in simulations* and the onboard computational power make it possible now. *Still, actual physical testing remains a must in aeronautics. https://www.aerospacetestinginternational.com/features/is-active-flow-control-the-next-step-in-flight-controls.html https://www.aerospacetestinginternational.com/features/is-ac...
- Terr_ 3y agoYeah, assuming you mean radar cross-section (which has surprisingly little to do with volume) as opposed to the conventional kind. If a non-flush screw can muck with the stealth profile, then surely flaps/ailerons can.
