Abstract

There is provided an inflatable dummy target comprising a chassis wrapped with a sheet. The chassis can be formed by individual inflatable ducts and can comprise at least two ring-shaped ducts interconnected by one or more elongate ducts. The inflatable dummy target can further comprise rigidizing ducts. The inflatable dummy target geometry can be conical, cylindrical, etc. Optionally, the inflatable dummy target can comprise several attached axi-symmetrical sections, wherein each section has a chassis wrapped with a sheet, the chassis formed by individual inflatable ducts. Optionally, the shape of each section can be selected from the group consisting of conical, frustoconical and cylindrical forms.

First claim

The invention claimed is:

1. An inflatable dummy target comprising a chassis wrapped with a sheet, the chassis formed by individual inflatable ducts, wherein
the chassis comprises at least two ring-shaped ducts interconnected by one or more elongate ducts, and
the dummy target geometry is conical shaped and the chassis 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.

2. The inflatable dummy target of claim 1 , wherein the sheet is attached to the chassis only at the base end and the apex.

3. The inflatable dummy target of claim 1 , wherein the chassis further comprises rigidizing ducts.

4. An inflatable dummy target comprising a chassis wrapped with a sheet, the chassis formed by individual inflatable ducts, wherein
the chassis comprises at least two ring-shaped ducts interconnected by one or more elongate ducts, each ring shaped duct is connected to at least one elongate duct, and
the dummy target geometry is cylindrical shaped and the chassis 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.

5. The inflatable dummy target of claim 4 , wherein the sheet is attached to the chassis only at the base ends.

6. The inflatable dummy target of claim 4 , wherein the chassis further comprises rigidizing ducts.

7. An inflatable dummy target comprising several attached axi-symmetrical sections, wherein
each section has a chassis wrapped with a sheet, the chassis formed by individual inflatable ducts, and
the shape of each section is selected so that the inflatable dummy target is comprised of a conical section attached to frustoconical section, thereby achieving a concave dummy target geometry or the inflatable dummy target is comprised of a cylindrical section attached to frustoconical section, thereby achieving a convex dummy target geometry.
