These seem to run counter to each other.<\/p>\n<p>A missile lacking forward fins typically has better long range kinematics (the ASRAAM, for example actually has beyond visual range capabilities), but the thrust vectoring shows a bias toward shorter engagement distances.<\/p>\n<p>It should be noted that the fore body strakes probably contribute a quite bit to aerodynamic maneuverability, particularly at high speeds (you will note that the ASRAMM below lacks them)<\/p>\n<p><img decoding=\"async\" src=\"http:\/\/img149.imageshack.us\/img149\/6083\/300pxaim132asraamea7.jpg\" \/><\/p>\n<p>The rocket motor is almost certainly relatively low thrust at launch, to allow for the vectoring paddles to work with relatively small actuators (the AIM-9X does not do this, but it is reusing an old motor).  Additionally, since the thrust vectoring has little benefit at higher speeds, where aerodynamics work better, it&#8217;s likely that they are jettisoned shortly thereafter in flight.<\/p>\n<p>The report states that the missile is an Imaging Infra Red system, and my guess would be that uses a scanning array, rather than a <a href=\"http:\/\/en.wikipedia.org\/wiki\/Staring_array\">staring array<\/a>  (go to the Wiki link, it explains the difference fully).  While there are applications where a staring array is crucial, such as astronomical devices, for AAMs, the advantages are in dispute, staring arrays are <span style=\"font-weight: bold;\">much<\/span> more difficult to manufacture.<\/p>\n<p>One possibility is that this is the product of South African and Chinese cooperation though, it looks a lot like the Denel A-Darter (see below).  Note that the A-Darter has a 6&#8243; diameter (166mm) as compared to the 5 inches of the Sidewinder, which implies superior kinematics because of greater fuel volume).<br \/><img decoding=\"async\" src=\"http:\/\/img141.imageshack.us\/img141\/3340\/aadarterpsl9.jpg\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ares recently posted a description of a new Chinese short range air-to-air missile.
