It was printed on an EOS EOSINT P730 nylon laser sintering machine, which fabricates plastic or metal objects, building up the item layer by layer. No fasteners were used and all equipment was attached using 'snap fit' techniques so that the entire aircraft can be put together without tools in minutes. The electric-powered aircraft, with a 2-metres wingspan, has a top speed of nearly 100 miles per hour, but when in cruise mode is almost silent. The aircraft is also equipped with a miniature autopilot developed by Dr Matt Bennett, one of the members of the team. Laser sintering allows the designer to create shapes and structures that would normally involve costly traditional manufacturing techniques. This technology allows a highly-tailored aircraft to be developed from concept to first flight in days. Using conventional materials and manufacturing techniques, such as composites, this would normally take months. Furthermore, because no tooling is required for manufacture, radical changes to the shape and scale of the aircraft can be made with no extra cost. This project has been led by Professors Andy Keane and Jim Scanlan from the University's Computational Engineering and Design Research group. Professor Scanlon says: "The flexibility of the laser sintering process allows the design team to re-visit historical techniques and ideas that would have been prohibitively expensive using conventional manufacturing. One of these ideas involves the use of a Geodetic structure. This type of structure was initially developed by Barnes Wallis and famously used on the Vickers Wellington bomber which first flew in 1936. This form of structure is very stiff and lightweight, but very complex. If it was manufactured conventionally it would require a large number of individually tailored parts that would have to be bonded or fastened at great expense." Professor Keane adds: "Another design benefit that laser sintering provides is the use of an elliptical wing planform. Aerodynamicists have, for decades, known that elliptical wings offer drag benefits. The Spitfire wing was recognised as an extremely efficient design but it was notoriously difficult and expensive to manufacture. Again laser sintering removes the manufacturing constraint associated with shape complexity and in the SULSA aircraft there is no cost penalty in using an elliptical shape." SULSA is part of the EPSRC-funded DECODE project, which is employing the use of leading edge manufacturing techniques, such as laser sintering, to demonstrate their use in the design of UAVs. The University of Southampton has been at the forefront of UAV development since the early 1990s, when work began on the Autosub programme at its waterfront campus at the National Oceanography Centre, Southampton. A battery powered submarine travelled under sea ice in more than 300 voyages to map the North Sea, and assess herring stocks. Now, the University is launching a groundbreaking course which enables students to take a Master's Degree in unmanned autonomous vehicle (UAV) design. This is the first scheme of its kind and from September 2011, postgraduates can take part in a one-year programme covering the design, manufacture and operation of robotic vehicles. The degree will cover marine, land based and pilotless aircraft, typically used in environments that are deemed unsafe or uneconomic, such as exploration under sea ice, or monitoring gas emissions from volcanic eruptions. NASA expects UAVs to become 'standard tools' in fields such as agriculture, earth observation and climate monitoring.[/QUOTE] Source: [URL]http://www.eurekalert.org/pub_releases/2011-07/uos-sef072811.php[/URL]
Gonna buy a 3-D printer asap

so it cannot man any pilots or something? how very useful...
[QUOTE=Gekkosan;31405910]so it cannot man any pilots or something? how very useful...[/QUOTE] yes, UAVs are shit
I remember finding UAV's creepy back in the time. :v:
[QUOTE=RichyZ;31405918]yeah planes need people to be useful, what the fuck were they thinking putting uavs in iraq[/QUOTE] well this paper plane doesn't strike me as an UAV.. UAVs can probably shoot and if not they can reveal enemy positions probably. Some shit like that.
[QUOTE=Gekkosan;31405952]well this paper plane doesn't strike me as an UAV.[/QUOTE] Well, a UAV is by definition an [B]Unmanned[/B] Aerial Vehicle. I don't see how this isn't a UAV unless you're suggesting The Great Gazoo is flying it.
[QUOTE=Gekkosan;31405952]well this paper plane doesn't strike me as an UAV.. UAVs can probably shoot and if not they can reveal enemy positions probably. Some shit like that.[/QUOTE] UAV = unmanned aerial vehicle so basically a flying robot it doesn't have to have guns on it to fit the criteria, hell it doesn't even have to be made by the military [editline]29th July 2011[/editline] and yeah, it is useful
[QUOTE=Gekkosan;31405952]well this paper plane doesn't strike me as an UAV.. UAVs can probably shoot and if not they can reveal enemy positions probably. Some shit like that.[/QUOTE] It said about five times that these were for laser mapping. You could still build other things in. That's the whole point here. It's east/fast/cheap to fix problems in the design. Also, these are 10x cheaper than building the exact same thing with other methods. This apparently can also print in some type of metal. I'm guessing aluminum. The fact that it doesn't have a gun on it doesn't mean that it's not useful. Also there are other fields that could benefit from this than military.
