Hypermixing Fluid Ejector
US Patent:
2009015, Jun 25, 2009
Filed:
Feb 1, 2008
Appl. No.:
12/024698
Inventors:
Fabio G. Grossi - Grapevine TX, US
International Classification:
F02K 3/00
US Classification:
60269
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.
Statically-Operating Ejector Ramjet
US Patent:
2009015, Jun 25, 2009
Filed:
Feb 1, 2008
Appl. No.:
12/024573
Inventors:
Fabio G. Grossi - Grapevine TX, US
International Classification:
F02K 7/10
US Classification:
60767, 60249
Abstract:
The present invention provides a statically starting and operating ramjet engine system. The system includes a pumping ejector coupled to a ramjet engine upstream of the ramjet inlet. A subsonic converging nozzle is placed in fluid communication between the pumping ejector and ramjet inlet. The pumping ejector ejects a primary fluid into the ramjet inlet to entrain a secondary fluid and create a mixed flow with sufficient momentum and internal energy to achieve characteristic speed. The converging nozzle provides a characteristic cross section necessary for the mixed flow to achieve characteristic speed as it moves through the nozzle, thereby producing a standing shock wave at the point of maximum convergence of the nozzle and creating sonic conditions at the inlet of the ramjet engine.
Pumping Ejector
US Patent:
2009016, Jun 25, 2009
Filed:
Feb 1, 2008
Appl. No.:
12/024646
Inventors:
Fabio G Grossi - Grapevine TX, US
International Classification:
F04F 5/00, F02K 7/10, F02K 1/00
US Classification:
417151, 60767, 60770
Abstract:
The present invention provides a fluid pumping ejector. The ejector includes a reservoir containing a primary fluid and a mixing duct. An ejector nozzle ejects the primary fluid from said reservoir into the mixing duct to entrain a secondary fluid and create a mixed flow with sufficient momentum and internal energy to achieve characteristic speed. A subsonic converging nozzle is coupled to the mixing duct downstream of the ejector nozzle and provides a characteristic cross section necessary for the mixed flow to achieve characteristic speed as it moves through said converging nozzle, thereby producing a standing shock wave at the point of maximum convergence of the nozzle. The ejector nozzle is fully-expanded, wherein exit speed of the primary fluid is supersonic and exit static pressure of the primary fluid is equal to secondary fluid pressure.
Ramjet Superheater
US Patent:
8381528, Feb 26, 2013
Filed:
Feb 1, 2008
Appl. No.:
12/024749
Inventors:
Fabio G. Grossi - Grapevine TX, US
Assignee:
Grossi Aerospace, Inc. - Grapevine TX
International Classification:
F02K 7/08
US Classification:
60767
Abstract:
The present invention provides a regenerative superheater system for an ejector ramjet engine. The invention includes a superheater in thermal communication with the combustion chamber of the ramjet engine. The superheater transfers thermal energy from combustion chamber to an ejectant which is then redirected upstream to the ramjet ejector. In one embodiment of the invention the temperature of the ejectant is modulated by a variable geometry cooler that controls the amount of thermal energy removed from the superheater system by ambient air. In an alternate embodiment of the invention, the temperature of the ejectant is modulated by a variable geometry superheater that controls the amount of thermal energy added to the superheater system through combustion gas.
