I've noticed a change in the aircraft nozzle lately in commercial / govt aircraft. Attack AC like the F18 do not have this nozzle

This is a schematic of a normal commercial jet engine. Notice the nozzle.


Now, I will show you pics of the new nozzle. Notice it has a hole in it. It also extends past the back, like a scramjet nozzle.

Any aviation experts able to help me on this one? What it the purpose of a hollow nozzle?

Please watch this video, of a typical CFM56 engine, used on ALL modern Boeing 737s, many Airbus 319, 320 and 340 --- among others.

www.uzood.com...

There is NO WAY that anything can be introduced into the engine, and "sprayed" out through the exhaust cone.

In the case of the small pipe you see out of modern turbo-fan engines, it is usually a vent for any unburned fuel that is residual after engine shut-down. That is all it is, a place for excess fuel to exit, so there isn't a pool of raw fuel sitting in the engine when it is started the next time.

I watched the video. I noticed the hollow exhaust cone, with no explanation for the purpose of this being hollow. The chemicals could be introduced aft of the turbine blades (furthest aft of engine). Chemicals could then be introduce into the exhaust stream. That is why is protrudes so far aft. It's like a spray gun.

I don't think so. I think chemtrails are produced in the vivid imaginations of some bored people who have a hard time understanding how hot humid air reacts when injected into a cold dry environment.

NO. You watched the video??


Could you not see how it's impossible to introduce anything into the exhaust, EXCEPT the hot gasses coming from the combustion plenum???

The shape of the exhaust cone in the middle, and the way it protrudes, is to make for an efficient flow of the exhaust gasses. They DO provide some added thrust component, and by making sure there is smooth flow it reduces drag, which enhances fuel conservation.

Really, this is not even a viable idea. Our EGT guages (that's Exhaust Gas Temperature) normally read in the 800-850 degrees Celsius, when engines are operating at high power levels. At idle, on the ground, the EGT is about 550 degrees!!! That's one of the things we glance at, as the engine is started, and "rolls back" to stabilize at idle...it's a simple pnemonic, "2-4-6". We look for N1 (the fan) in the 20% range, the N2 (turbine hot section) in the 40% range, and the EGT near 600 (well, slightly below, of course....but you get the point).

Heck, don't believe me if you don't want to. Go to an airport and ask an engine mechanic, tell him your "theory". He might not laugh, if he's polite.

I already told you why. I've been up close and personal to these engines for years. FUEL drips out, on the ground, from the center opening of the exhaust cone!!!

I've seen it discussed here, but never really "settled". What about the "chemical" being processed by being AN UNSUSPECTING OR DIFFICULTLY TRACEABLE ADDITIVE TO THE FUEL?

Especially one that is "activated" through heat.

This would work, no?

First, you say that nothing can get into the center of the cone, then you say you've seen fuel drip out of them. How did the fuel get there, then?

Like this?

Chemtrails - JP8 & EDB


Since early on in the Chemtrails investigation, it was reported that JP8 fuel, the fuel used commonly by military jets, contained EDB, ethylene dibromide, a known carcinogen. And, necessarily then, if Chemtrails were made by military jets, we, an unwitting public, were breathing in EDB. This was, in part, based on the report of a laboratory sample of "aviation fuel" that was cited in an early Chemtrails investigation story.

**sigh**

The fuel is introduced into the combustion plenum to be burned, when there is ignition present. When we shut down a jet engine, we use a lever which actuates electic valves which close off the fuel lines, right near the "Fuel Control Unit", which is the last item the fuel is routed to before it is sprayed through the nozzles to be combusted.

Small traces of fuel, left in the lines FROM the FCU to the nozzles will drip into the combustion plenum, after shut-down. That fuel is not allowed to just sit there, and pool in the bottom of the burner 'can', as it's called. BECAUSE, next engine start, chance of that igniting and blowing fire out the tailpipe. Not really dangerous, but puts undue uneven heat stress on the components...AND at night, there have been cases of jittery passengers initiating their own evacuation, in a panic because they think the engine is on fire!!!

SO...residual fuel is given a way to drip out, onto the ground, when the engine is sitting and not running.

Capiche??

Ferris.Bueller!! You didn't copy/paste some of the more important parts. NOT EVERYONE is going to click on the link!!!

Fromn the rest of the report:

All the research that I have done on this subject has turned up nothing to support the claim that JP8, or JP- 8+100 (military jet fuels) or any other military or commercial fuels, contain EDB now, nor did they ever.

So, again, to set the record straight, I am sharing some of my research notes on this subject with readers to allay any fears that Chemtrails are causing us to breathe in carcinogens in the form of EDB. This is research gleaned from interviews with Mr. Chuck L. Davis of NASA,s Fuel Propulsion Studies, the United States Air Force, an independent researcher at the University of North Carolina, and the Environmental Protection Agency.

This is an interesting subject, though when I first heard about it I "poo pood" the idea. Then I saw a documentary on the history channel which talked about cloud seeding, and how it was first done in the USA back during the dust bowl era (1930's) to try and bring rain in. True scientific experiments started in the 40's.

The major types of weather modification that are currently in use or under study include cloud seeding, frost prevention, fog and cloud dispersal, hurricane modification, hail suppression, and lighting suppression.

Read more: science.jrank.org...


So, I did a bit more research, and sure enough, many countries practice cloud seeding, the United States being one of those countries. It is not done, to my knowledge, through commercial airlines though.

Russia and China are believed to be two countries that use it most. China used cloud seeding before the Olympics to try and control the rain during the games. www.scientificamerican.com...

All three cooling agents can be used to either induce or suppress precipitation, depending on the amount that is administered and the condition of the clouds


en.wikipedia.org...

www.universetoday.com...

The Nevada State Cloud Seeding Program cloudseeding.dri.edu...

Airports widely also use a technique which gets rid of fog to help with visual conditions.

I am not sure I see a "conspiracy" involved with cloud seeding, though I know that many others have more knowledge about this than I do.

In the news

www.indopia.in...

Los Angeles engaged in cloud-seeding from the 1950s to the 1990s
www.guardian.co.uk...


But other areas, including nearby Santa Barbara, have continued to use the method, typically employing airplanes or ground-based generators to spray silver iodide above mountains and watersheds.


news.google.com...

www.hindu.com...

So, does cloud seeding take place? Yes, it does. Is it in the news very much? Seems to be it is a little bit, but that it is generally not in the news very much. I am sure it happens more than we hear about. From what I could find, most states in the USA which are having drought use cloud seeding. Some will use it more in the winter to increase snow fall.

Several Universities, one I linked to above in Nevada, have cloud seeding experiments.

The controversy seems to be, not does it cause harm to the planet, but does it actually work. So far, the agreement is that it works, but only if moisture is already in the area of seeding. My question is, how damaging is it to humans, animals and the planet? Seems to be the agreement between professionals (LOL) is that it does not cause any harm. Not sure how much of that I believe. So maybe that is where the true conspiracy is, how harmful is it, not does it actually happen, because it does happen.

Harm None
Peace

Sorry. I was just providing an example of the 'fuel additive causing chemtrails' idiocy hypothesis MJ was asking about.

As I said before, chemtrails are just the product of the imagination of illinformed individuals.

You haven't even come close to explaining the reason for the hole in the end of the exhaust cone/nozzle. I can understand it being hollow, for weight savings, but the hole makes no sense unless it is a nozzle for injecting chemicals into the jet exhaust stream.
Capiche?

Before you get to condescending, I held an A&P license back in the 90's

This question would best be answered by an aviation professional on an aviation forum, rather than a forum where members either don't know much about aircraft, or simply don't care about chemtrails. I suppose I'll search for an answer. What I DO know however, is engines have many vents, ducts, and so on throughout them, and engines have had these for a VERY long time.

My question seems obvious to me, but hey...

Why would they even bother trying to incorporate this stuff in the fuel? It's not like we can see the thing when they've got so much altitude we can barely make out their shape.

Why not just put actual spray nozzles on the wings, and spray till your heart's content?

If you're spraying you're spraying - if you're not, you're not. Why would they even consider using passenger jetliners (the only reason I can think of that would warrant mixing something in the fuel) when they have so many other covert ways at their disposal?

And if there truly is this ED8 in the fuel, what do they care when their only concern is profit?

Because the 'chemtrail theorists' believe a large proportion of military and commercial aircraft are owned and operated by a cabal of governments and companies; otherwise known as Illuminati, the Masons, New World Order, and other assorted names; that want to eradicate 90%+ of the world's population. And what better way to do this than through crop spraying the world's population with toxic chemicals and biological agents with military and heavy commercial aircraft?

EDB is NOT being used, anymore. NEVER in jet fuel, anyway...WAS in automobile fuel, for decades and decades. It was known, then, as "leaded" gasoline:


1,2-Dibromoethane is the chemical compound with the formula BrCH2CH2Br. Although trace amounts occurs naturally in the ocean, where it is formed probably by algae and kelp, it is mainly a synthetic. This a colorless liquid with a sweet odor, detectable at 10 ppm, is a widely used and sometimes controversial fumigant.

-------------
Uses

The once dominant use, although one that has faded, is as an additive in leaded gasoline. 1,2-Dibromoethane reacts with lead residues to generate volatile lead bromides. It has been used as a pesticide in soil, and various crops. The applications were initiated after the forced retirement of 1,2-dibromo-3-chloropropane (DBCP). Most of these uses have been stopped by in the U.S. It continues to be used a a fumigant for treatment of logs for termites and beetles, control of moths in beehives, and as a preparation for dyes and waxes.

Source

Now....doesn't it make a lot more sense, IF the Powers That Be were trying to "poison" the people, wouldn't they do it with automotive and truck fuel???

I'm getting tired of repeating this --- Jet fuel is sold by the gallon, or litre, or course. BUT, once pumped onboard, the quantity is measured in weight, either in pounds or kilograms, depending on nationality. ANY change in the density of the Jet fuel, such as added metal particles or some such rubbish, will be noted in the fuel system measuring devices onboard the airplanes. When we get fuel, EVERY TIME the amount, in gallons here in the USA, is recorded, and then that is multipliled by the weight, and it is compared to the fuel guages. It is a double-check, and if they fuel was altered, pilots would see it immediately.

AS to OP, again: Since there is no way to plumb anything INTO the exhaust system, or into the center of the 'cone', the argument is moot. HOWEVER, just for one more nail in the coffin, there is NO WAY a passenger jet can have a quantity of "something" on board that the crew doesn't know about. It would require some sort of holding tank, and associated plumbing, pumps, valves, etc. This stuff would NOT be invisible!

The OP was an A&P (Aircraft & Powerplant FAA mechanic). He should understand this.

Pilots; Mechanics; Ground crew; ALL are crawling around the airplanes, nothing could be "hidden".

Your argument about the added weight shows your lack of knowledge in the area of cloud seeding/weather manipulation.

200 lbs of silver iodide will cover the entire US in silver iodide smoke. How much does smoke weigh?

Still, with all your supposed knowledge, as you seem to have an answer for everything, you cannot explain why there is a hole in the nozzle.

I will repeat it again for those lazy enough not to do any research on this subject.

Chemtrails will kill millions, if not billions. It is the worse crime EVER to be perpetuated on mankind.

REALLY? 200lbs? You have a source for that?? Because, I just looked up the area of the CONUS. It's at least 3,500,000 sq miles. let's do some math: That means ONE POUND has to cover 17,500 sq. miles. OR, put the other way, each square mile will have 0.000058 pounds of silver iodide on it. That's 0.0019 ounce.




Still, with all your supposed knowledge


Ah, the inevitable old ad hom...


...you cannot explain why there is a hole in the nozzle.


I have explained. TWICE.


EDIT to repeat from above post (because soemone isn't reading it, apparently):

I wonder how silver iodide, a water-insoluble antimicrobial compound, is going to be used to kill off 90%+ of the world's population?
