Benefits of technology

[0020]It is an object of the invention to provide improved elements and arrangements thereof in an apparatus for the purposes described which is inexpensive, dependable and fully effective in accomplishing its intended purposes.

Problems solved by technology

None of the prior art, however, teaches the conversion of the exhaust from a cylindrical plume into a 3D spiral formed by a twisting ribbon.
However, none teach the application of a slit-shaped exit to control the flow of a jet exhaust to resemble a 3D spiral.

Embodiment Construction

[0035]The present invention is directed to a propulsion system for a jet- or rocket-propelled vehicle, including aircraft and watercraft. In particular, the invention is directed to a modification in which the jet propulsion exhaust exiting the jet nozzle is oriented in a 3D spiral created by an elongated S-shaped opening. The present invention may be used with any type of propulsion exhaust and is not limited to gas or water exhaust.

[0036]FIG. 1A shows a propulsion system of the present invention including a jet engine having a jet nozzle 14 which includes an attachment 10 applied to the nozzle 14 having a slit 12 defined therein. The flow of the jet exhaust from a conventional jet engine is typically a cylindrically shaped plume or contrail that progressively expands. The exhaust plume 20 of the present invention, however, is intended to be particularly in a 3D spiral configuration, as shown in FIG. 1A. As shown in FIGS. 1A, 1B and 1C, the exhaust nozzle 14 has been modified by th...

Abstract

A propulsion system for a jet- or rocket-propelled vehicle in which the resulting jet exhaust nozzle profile is a 3D spiral. The propulsion system can be applied to any jet- or rocket-propelled vehicle, including aircraft and watercraft. The propulsion system also contemplates a vehicle including the modified 3D spiral nozzle exhaust profile

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of U.S. Provisional Patent Application Ser. No. 60 / 421,791, filed Oct. 29, 2002.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a jet propulsion system. More specifically, the invention relates to a jet propulsion system having a jet or nozzle modified to produce a jet exhaust formation having a 3D spiral formation by using a slit to produce spiral exhaust for improving performance and handling, as well as reducing drag (i.e., jet and rocket engines), thereby increasing speed. The slit preferably has a generally S-shaped configuration.[0004]2. Description of Related Art[0005]Jet propulsion is well known in both the fields of aircraft and marine vehicles. The exhaust of these vehicles is produced by rotating power plants, such as compressors and turbines, producing thrust. The resulting exhaust leaves the nozzles of these vehicles in a generally cylindrical...
