ASN4G missile




 As a successor of famous French ASMP missile, ASN4G missile is in proposal status. Interesting thing of the proposal is that it aimed high supersonic of hypersonic speed which possibly use scarmjet. 

 Layout of the missile is bizarre compare to other scramjet experimental vehicles; it has lex and inner angled inlet with boundary layer terminations. Inner angled inlet is attempted in F-105, however inner angled inlet with complex lex is certainly not usual in hypersonic speed. 

 Lex and smoothened body is expected to generate more lift than the conventional missile body in high speed for increase of maximum range. Complex shape of shock wave is expected between the inlet and body because inner angle induced wave is reflected at the body. If it is properly designed, the inlet could reduce free-stream Mach number through many small shock helpful to reduce shock loss. 

 Exhaust part of the engine is angled and it is expected to provide proper shock wave pattern or lift. Tail fin of the missile seemed to be large for its size, and it is expected to have high dive angle at terminal phase of the maneuver to maximize its penetration or destruction effectiveness. 

 Physical size of the missile might be smaller than that of Russian one (http://jaesan-aero.blogspot.kr/2018/03/russia-released-hypersonic-weapon-from.html). The limitation of the size is caused by platform size of the French (size of the Rafale is smaller than MiG-31 or Su-27 class fighters)
