Grid Method Based Store Separation Suite Using PARANAM Mesh Free Solver

A  store  separation  suite  based  on  Point  Prediction  methodology  was  developed  at  CSIR-National  
Aerospace  Laboratories  (NAL)  using  PARANAM  (P
arallel  NAL  MCIR)  mesh  free  CFD  solver  along  
with  6-DOF  code  and  dynamic  point  cloud  pre-processor  [7,8].  This  store  separation  suite  is  well  
validated and tested and is being used widely for va
rious strategic store separation projects at CSIR-
NAL [7,8]. However, in some scenarios point predic
tion based method is difficult to employ owing to 
either large number of trajectory studies or time 
and resource requirements. In such scenarios a quick 
but sufficiently accurate method is needed. The 
Grid method which is an approximate method based 
on aerodynamic database has been used to develop a 
store separation suite to achieve the same. In 
this  work  we  have  exploited  mesh  free  nature  
of  PARANAM  solver  to  generate  the  aerodynamic  
database required for Grid method efficiently. The 
suite has been applied to standard Eglin test case 
for  carrying  out  validation.  Furthe
r  we  have  demonstrated  the  utility  of  such  a  tool  in  parametric  
studies for assessing sensitivity.
