   If you want a detailed description with equations and data, you're   
   looking for peer reviewed papers, not high level summaries like in the   
   cites given so far.  I'd start with AIAA Publications.   
      
   https://www.aiaa.org/Publications/   
      
   Or look at NTRS (NASA Technical Reports Server).   
      
   https://ntrs.nasa.gov/   
      
   You'll find papers like this:   
      
   MULTIDISCIPLINARY APPROACH TO LINEAR AEROSPIKE NOZZLE OPTIMIZATION   
   J. J. Korte*, A.O. Salast, H.J. Dunn?, and N.M. AlexandrovP   
   NASA Langley Research Center, Hampton, Virginia 23681   
   and   
   W.W. Follett*, G. E. Orient*, and A.H. Hadid$   
   Rocketdyne Division of Boeing North American, Canoga Park, CA 91309
