Benefits of technology

The patent describes using a flat plastic sheet as an extension attached to a plastic carbonated drink bottle to create a point of attachment for stabilizing fins. The sheet is made into a cylinder using strong adhesive tape, which is attached to the bottle using tabs integrated with the sheet. The cylinder provides a base for the fins, positioning them lower on the bottle to increase their aerodynamic effect. The attachment system is resilient and minimal in aerodynamic drag. Overall, the invention improves the stability and aerodynamic efficiency of plastic drink bottles.

Problems solved by technology

Many of the existing methods used to build water rockets are impractical, heavy, unreliable, time consuming, and ineffective.

Embodiment Construction

[0014]FIG. 1 is a plan view of the fin attachment system (100). The fin attachment system consists of a transparent plastic sheet (1) including an adhesive strip (2) and multiple tabs (3) with adhesive (4). A water fill line (5) is pre-printed at the location shown. The width (6) is sized to match the circumference of a plastic drink bottle. The overlap (7) containing adhesive strip (2) is used for forming the plastic sheet (1) into a permanent cylinder to fit tightly around a plastic drink bottle. The fin target box (8) is used to properly align stabilizing fins.

[0015]FIG. 2 is an isometric view of the transparent plastic sheet (1) formed into a cylinder (200) held together by adhesive strip (2). When placed over a plastic drink bottle the cylinder (200) is attached using tabs (3) and adhesive (4). The water fill line (5) represents the recommended water amount for rocket flight. The fin target box (8) provides a target location for proper alignment of fin. Only one fin target box ...

Abstract

A plastic sheet that can be formed into a cylinder or truncated cone and attached to a pressure vessel by use of integral self-adhesive tabs. The cylinder or truncated cone is then used as an extension and structure for the attachment of rocket fins.

Many of the existing methods used to build water rockets are impractical, heavy, unreliable, time consuming, and ineffective. This fin attachment system is unique, practical, light weight, reliable, and effective.BRIEF SUMMARY OF INVENTION[0007]In one embodiment, a flat plastic sheet, of the appropriate dimensions, is used as an extension attached to a plastic carbonate...
