Brisse Posted August 15, 2012 Posted August 15, 2012 Swedish website "NyTeknik" has written an article that reveals several future plans for the Swedish multirole fighter JAS-39 Gripen. The one that catches the eye most is the plans for an unmanned version of the next generation version JAS-39. The article states that this will not be a regular UAV in todays sense, but a full blown multi role figher without a pilot. If this becomes reallity, the Swedish air force will replace it's current fleet of JAS-39 by 2030 and will then operate both manned and unmanned versions of the new generation JAS-39. Interesting stuff? :smartass:
marcos Posted August 15, 2012 Posted August 15, 2012 Cool but many of the performance advantages of an unmanned aircraft will be limited if using a manned aircraft as the basis.
tflash Posted August 15, 2012 Posted August 15, 2012 Yes, but maybe the airframe already has a higher performance envelope which is now limited by the FBW to be within the limits of the human pilot? [sIGPIC][/sIGPIC]
Brisse Posted August 15, 2012 Author Posted August 15, 2012 Yes, but maybe the airframe already has a higher performance envelope which is now limited by the FBW to be within the limits of the human pilot? It depends on the fuel quantity and external loads but I am sure it can handle way more than 9G's without any external loads. The 39's in service today has Manoeuver Load Limiter that varies with the loadout. It also has an alpha limit around 50 degrees but when it was developed it was tested all the way to 110 degrees while retaining controllability.
Brisse Posted August 15, 2012 Author Posted August 15, 2012 Found some questionable sources stating that the Airframe can take 12G's. I also found a reliable source stating that the 39 can go from 1G to 9G in less than one second. Sounds scary :)
marcos Posted August 15, 2012 Posted August 15, 2012 But if you designed from scratch you could remove the entire cockpit, all instrumentation, OBOGS etc. and end up with a far lighter aircraft with less drag.
tflash Posted August 15, 2012 Posted August 15, 2012 True, but designing from scratch is a lenghty and costly process, just as designing a fighter aircraft. No wonder that the idea comes to mind to build on what you already have. Gives you some commonality in maintenance, spare parts, etc. as a bonus. [sIGPIC][/sIGPIC]

That's what they said about the Nimrod MRA4.:megalol: The technology for UAVs to go off on a mission without control input has been around for a while but so have the ethical considerations.
