ABSTRACT	The Quiet Short Take-Off and Landing(QSTOL)Experimental Aircraft “ASKA” has been researched and developed by the National Aerospace Laboratory(NAL).The “ASKA” was based upon the airframe of the home produced C-1 tactical transport which was modified into the Upper Surface Blowing(USB)-powered high- lift STOL aircraft.The wing configuration,however,was not changed.Therefore,this Experimental Aircraft dose not always havend Tunnel with closed section and results were obtained for several flap and slat deflections at jet momentum coefficients from 0 to 1.85.Compared with the aerodynamic characteristics of the “ASKA” model,we determined that the airframe weight can be reduced and the aerodynamic characteristics can be improved significantly.
