The inline pressure jet engine, the Pulesram story

2010-12-10T10:51:00.002-05:00

Draft in progress

The development of the inline pressure jet from the original L shaped pressure jet of Eugene Gluharef is a long and interesting story, I will try to cover the more salient points and a few of the major players involved in the development of the original pulsejet and pressure jet.


Original L shape pressure jet by Eugene M. Gluhareff

The basic L shaped pressure jet is an efficient self starting combustor but limited to propane fuel and is some what bulky for industrial heating applications, it was my primary goal to solve the latter issue first as propane fuel at the time was a reasonably cheap and acceptable fuel.

Another design goal was to limit its use to industrial heating applications rather than propulsion by deliberately designing certain constraints in to its geometry, these modifications to the fundamental design language of the engine could not be removed by any one who did not possess the actual design formula, this last goal was more time consuming than I at first realized, but in the end as Eugene proved before me, it was well worth taking the time at the beginning to protect my ideas later.

They went with songs to the battle, they were young.

Straight of limb, true of eyes, steady and aglow.

They were staunch to the end against odds uncounted,

They fell with their faces to the foe.

They shall grow not old, as we that are left grow old:

Age shall not weary them, nor the years condemn.

At the going down of the sun and in the morning,

We will remember them.

Patent, Combustor configurations

2010-09-03T12:19:00.002-04:00

Recently I have come across some confusion over my original patent (WO/2007/003031) COMBUSTOR CONFIGURATIONS and what it is intended for, I originally conceived this particular innovation as an efficient propane burner for industrial use in cold climates, the target market was for rail track switch heater use in unattended locations were its lack of moving parts and electrical requirements would have been a real advantage, the burner also functioned as its own “blower” this was a major selling point.

It is “not” as misrepresented by at least one unscrupulous promoter, a flight engine or propulsion engine suitable for use on Drones or UAV’s or “some kind of stationary ram jet”, I very deliberately designed this burner so that it could not be used for propulsion, this was a security feature that could not be removed and was designed in from the start, why? the burner was originally conceived for unattended use in remote locations with poor or none existent security, deliberately limiting its use to a burner lowered its theft risk or the risk.

At the time of its conception the world was experiencing an upheaval due to terror attacks and this weighed heavily on my mind, it was a primary goal of the design that it could not be used with out my authority in any way for military drones or subverted for illegal acts, with this as a primary goal I deliberate placed a number of constraints in to the design of the burner in the same way that Eugene Gluhareff before me secured his own design.

My third pulse jet related patent will be for propulsion, this would be independent of my first or second patents in the burner series.

Acoustics books

2010-08-16T13:43:00.002-04:00

I am often asked which books I would recommend on acoustics for those trying to develop their own pulse jets, in the coming months I will slowly add to this article on some of the books that have helped me over the years.

This is a much cheaper book and suitable as a basic primer with examples of flow and some calculations used, recommended for your library book shelf
.

This is one of my favorite books on acoustics in a real world situation of varying flow and pressure, a lot can be gained by studying a topic in a related real world situation to the one that your problem is in, the theory of engine manifold design shows you real world maths and flow examples.

Although Acoustics of ducts and exhausts is admittedly an expensive book, I have to say it is pretty good for those needing an in depth look at the underlying principles of acoustics in real world situations, I purchased two copies of this title originally, one for my project company office and one for my home office.

Conception GLC inc. is bankrupt!

2010-08-06T15:07:00.038-04:00

Conception GLC inc. is closed, this will not come as much of a surprise for any one who has followed this sad saga the last few years, but maybe for the share holders who had invested over $550,000 in the company it is a surprise, this is because no official announcement was made to them ether by letter or even by a simple email.

More on this subject can be found by going to the unofficial public announcement made by Luc Laforest, who is the ex president of Conception GLC inc, this announcement was made via his personal forum account and not that of the company, here is the link Pulse-Jets.com forum.

(Please note that although I provide a link to the post and to the forum it is only as a courtesy and does not imply any official relationship or ownership to the post, author, or forum)

Any of the original investors of Conception GLC are more than welcome to contact me privately to discuss the history of this company and the promises it made.

A Brick, Twice as long as it is wide.

2010-07-28T12:05:00.005-04:00

My other blog is called a A Brick (for short) but the proper title is Twice as long as it is wide but only half as long, originally this started as a design based blog but has developed over the years to include wider ranging subject matter.

The title of the blog comes from an old English insult to do with being thick as a brick but that's another story, it also applies to the trade of bricklaying

Monsieur le commentaire is intended to cover more pulse jet and turbo jet related engineering subjects as well as cover French language postings.

New content

2010-07-27T12:42:00.001-04:00

Some new content will make its way here as soon as I can get some time but for now we will be doing a clean up to get ready and make room for the pulse jet related stuff to move here.

Welcome

2009-11-10T13:52:00.002-05:00

I have been meaning to get around to writing a new personal blog for ages and this is the first chance I have had recently to do the basic set up, I would like to make pulse jets and intermittent combustion the main theme for the new blog
