Problems solved by technology

However, the Fono ramjet has no direct means for completing the Brayton cycle and creating sonic inlet conditions.
The Fono ramjet conundrum prevents this propulsion concept from operating statically (unmoving) which is an obviously severe limitation for reducing to practice.

Embodiment Construction

[0039]The most obvious benefit of ramjet theory is the simplicity of design and construction. However, there are no ramjet engines made available to the marketplace for general application. The few working examples are limited to military applications for expendable weaponry. The limiting issue for ramjet application is the ramjet conundrum.

[0040]The present invention solves the ramjet conundrum by artificially creating sonic conditions at the ramjet inlet by means of a pumping ejector used to force air through the subsonic diffuser at the front of the ramjet.

[0041]The term “ejector ramjet” within the art of propulsion includes a broad array of configurations that comprise any combination of an ejector with a ramjet. The ejector can be mated to the ramjet in any location and be either integral or accessory and have either reactive or inert fluids. The ramjet can be a classical Fono type or supersonic-combustion type. Components are combined to solve specific propulsion problems. The...

Abstract

The present invention provides a hypermixing fluid ejector. The ejector includes a reservoir containing a primary fluid and an ejector nozzle with a trailing-edge array of rectilinear orifices. The primary fluid is ejected through these orifices to entrain a secondary fluid, thereby creating a mixed fluid flow. A dividing line is defined on the trailing surface of the nozzle that is orthogonal to the linear axis of the ejector, and the orifices alternate above and below this dividing line in an abutting, offset manner. The orifices are geometrically inclined to produce spray cones that are convergent relative to this dividing line, resulting in convergent helical hypermixing of the primary fluid with the secondary fluid.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of and priority to U.S. Provisional Patent Application 61 / 016,289 filed Dec. 21, 2007, the technical disclosures of which are hereby incorporated herein by reference.[0002]This application is also related to co-pending application Ser. No. 12 / 024,573 entitled “Statically-Operating Ejector Ramjet,” Ser. No. 12 / 024,646 entitled “Pumping Ejector,” and Ser. No. ______ entitled “Ramjet Superheater,” concurrently filed herewith.TECHNICAL FIELD[0003]The present invention relates generally to fluid ejectors and more specifically to a design for an ejector with a hypermixing fluid nozzle.BACKGROUND OF THE INVENTION[0004]A ramjet is a type of air breathing propulsive engine that uses fixed components to compress and accelerate intake air by ram effect. It is also affectionately known as the flying stovepipe.[0005]FIG. 1 shows the basic elements of a ramjet power cycle and flowpath in accordance with the prior art...
