Shape Changing Plane In Development 212

Posted by ScuttleMonkey from the making-toys-a-career dept.
Eh-Wire writes "The University of Florida has a short article on the "morphing wing" drone they are developing for a small aircraft that can swoop through parking garages, dive into alleys and land on balconies. Close-up video of seagulls in flight was the inspiration for the design of the drone. A still image of the drone shows an aircraft that looks surprisingly gull-like. A video shows the "wing morphing" in action on a static mounted drone. There is also a link to quite a few more videos in the article but it's not real obvious. Some guys get all the phun jobs!"

    Looking at the differences between a bird and an airplane one can see obvious benefits of each. What conventional aeronautics have not been able to acomplish is the agility and dexterity with wich birds can manuvere in flight. Birds also have an incredible ability to fly at slow speeds and even recover from dangerous situations. All of these qualities are what we NEED in our future aeronautical designs.

    As a Private Pilot I was getting excited by the prospect of the Mohler Flying Car, or even one of those (relatively) cheap DIY helicopters. But there was always something in the back of my mind that said that aircraft NEED to be more like birds.

    Admittedly, the technology ISN'T as impressive as one would imagine. BUT, I applaud any attempt at changing the way things are done. In fact, I read an article yesterday that claimed that Japan is doing experiementation with a supersonic (Concorde-like) aircraft! Lets see what the future holds: flying cars, supersonic flight for everyone, personal helicopters, more agile designs, deployable parachutes, better computer assisted flight (from GPS, ALS, to auto performance enhancements).....

    Its about time someone in the field of aeronautics changed things....things have remained the same for WAY TOO LONG.

    My favorite variable geometry aerodynamic structure is R. T. Jones' oblique all wing [hiller.org] (PDF warning). Its basically just a highly eccentric elipse that flies. At 0 its angle of attack is 0. At Mach 1.6 its angle of attack is 60 degrees. As an SST topping out at Mach 1.6 it can achieve per-passenger fuel economy similar to a subsonic jumbo jet.
    • Wasn't there a plane that could do that with just its wing? It still had a normal plane fuselage, but the wing would rotate to achieve better geometry for different flight modes. Maybe it was just a prototype though, I can't remember where I saw the info.

    Wing-morphing on real airplanes is usually done thru the auspices of flaps, droops and leading-edge slats. These are the sucessful morphing methods, as seen on almost every high-performance airplane.

    If they're particularly adventurous, the designers will do ti by making the wing sweep angle changeable, like in the F-111, F-14 and B-1. Hmmm, two dogs out of three....

    It hasnt been done the way this video depicts in real planes as there's a lot of costs:

    • Making the wing hinged or flexible means you need a whole heapin helping of actuators to keep it in position. Actuators are made of steel-- very heavy. if it's a fighter plane, the actuators have to be able to hold the wing in position under multiple-G loads. But that requires heavier actuators, which increase the loads...
    • Actuators are usually hydraulically powered. Not good in a military airplane which often loses hydraulics due to flak and bullets.
    • Hinged or flexible wings usually can't be hollowed out to hold fuel, landing gear, or munitons. Which makes the rest of the plane bigger in proportion to hold those items.
    So you end up with a plane that's big, heavy, unreliable all the time, versus having the flexible wing, which only helps in some flight regimes, some of the time. Generally the good doesnt outweigh the bad.
