Method for performing exo-atmospheric missile's interception trial

Abstract

An inflatable dummy target comprising a chassis of inflatable ducts wrapped with a sheet. The chassis of inflatable ducts can include one or more ring shaped ducts and one or more elongate ducts. The chassis can include at least two ring shaped ducts interconnected by one or more elongate ducts. The dummy target can include several attached axi-symmetrical sections, each section have a chassis of inflatable ducts. Each section can be conical, frustoconical or cylindrical, thereby achieving a concave or convex dummy target geometry.

1 . An inflatable dummy target comprising a chassis of inflatable ducts wrapped with a sheet. 
     
     
         2 . The inflatable dummy target of  claim 1  wherein the chassis of inflatable ducts comprises one or more ring shaped ducts and one or more elongate ducts wherein each ring shaped duct is connected to at least one elongate duct. 
     
     
         3 . The inflatable dummy target of  claim 2  wherein the chassis of inflatable ducts comprises at least two ring shaped ducts interconnected by one or more elongate ducts. 
     
     
         4 . The inflatable dummy target of  claim 2  wherein the dummy target geometry is conical shaped and the chassis of inflatable ducts comprises a ring-shaped duct positioned at a base end of the chassis connected to a plurality of elongate ducts extending therefrom and angled inward and converging at an apex end of the chassis. 
     
     
         5 . The inflatable dummy target of  claim 4 , wherein the sheet is attached to the chassis only at the base end and the apex. 
     
     
         6 . The inflatable dummy target of  claim 4 , wherein the chassis of inflatable ducts further comprises rigidizing ducts. 
     
     
         7 . The inflatable dummy target of  claim 2  wherein the dummy target geometry is cylindrical shaped and the chassis of inflatable ducts comprise a first ring shaped duct positioned at a first base end, a second ring shaped duct positioned at an opposite base end of the chassis, and a plurality of elongate ducts connected to the first and second ring shaped ducts and extending therebetween. 
     
     
         8 . The inflatable dummy target of  claim 7 , wherein the sheet is attached to the chassis only at the base ends. 
     
     
         9 . The inflatable dummy target of  claim 7 , wherein the chassis of inflatable ducts further comprises rigidizing ducts. 
     
     
         10 . The inflatable dummy target of  claim 1  wherein the dummy target is made of several attached axi-symmetrical sections, each section have a chassis of inflatable ducts. 
     
     
         11 . The inflatable dummy target of  claim 10  wherein the shape of each section is selected from the group consisting of conical, frustoconical and cylindrical. 
     
     
         12 . The inflatable dummy target of  claim 11  comprised of a conical section attached to frustoconical section, thereby achieving a concave dummy target geometry. 
     
     
         13 . The inflatable dummy target of  claim 11  comprised of a cylindrical section attached to frustoconical section, thereby achieving a convex dummy target geometry.
