As long as the info ain't too sensitive, could someone answer a question about the thrust vectoring exhaust for me? I know the thrust vectoring nozzles are used to increase pitch response as well as control at low speeds and high alpha, but do they help at all with control about the roll axis? It shouldn't be too hard to program them for differential actuation, but do they actually perform in that capacity? Like I said, no discussion of classified information please .

Hi Parrothead,

It would be a bit of a waste if they didn't. I found this from GlobalSecurity http://www.globalsecurity.org/military/ ... 2-f119.htm

"...The two-dimensional nozzle vectors thrust 20 degrees up and down for improved aircraft agility. This vectoring increases the roll rate of the aircraft by 50 percent and has features that contribute to the aircraft stealth requirements..."

Great info. Thanks for the post. Razz

You dont have to come on in Taco, its youre choice. So dont blame me for youre choice to start posting. Youre old enough Im sure. I have given facts to support my claims, look at the last pages. I back my side up. You,and etc members havent. You are just changing the subject all of the time, very typical of Su/Mig haters. Am I wrong? No. You are just mad. As far as what do I do. Its simple. I work for Boeing at the Everett plant, in Wa, as flight instrument trouble shooter. I talk to former military, and current guard pilots on a regular basis. As jets are checked out, for the final roll out. You want proof of my job, please pm me. Its not top secret, I promise.

I have tried to get back on topic on page 4, but than sh*t happend and weve lost the course. So I agree with you on that one Taco.

By the way I just had a TACO, and it was good.Ummmmmmmmmm

Or rather Maid of Honor?...but seriously lets get back on topic.

You know, that implies something about me too! Laughing

thrust-vectoring on the F-22 is a bit of an overkill. I can't help but seeing it as a redundancy.

Well....somebody has to play the part.

Go on...are you implying the F-22 could hold its own without thrust-vectoring? Of course I'm talking about flight control issues not thrust.

I disagree here. We've backed up our opinions every time as far as I'm concerned. I only see opinions where you're concerned. TC has been checked out by my personal sources and found to be truthful. You don't have to believe me or believe that I have sources as that's your right. I'm really past the point of caring. The point I'm trying to make here is that we all know your opinion and so far nobody else agrees with you. You've gotten into personal attacks such as

It would be nice to have a fighter pilot's opinion about TV. I'm out of my league here.
Nonetheless, the F-22 is the most expensive and advanced fighter there is. Without thrust-vectoring, the F-22 is the most expensive and advanced fighter there is. IMO, what makes the F-22 valuable is its sensor suit, supercruise, armament and stealth. Perhaps there will be situations where TV will make the difference, I just don’t have the imagination. I also believe that the F-22, TV or not, has/would have benefited from the design rules of its predecessors and technology demonstrators. Unless the stealth design taxed it’s maneuverability, I don’t see how TV will provide a high benefit-to-cost ratio.

You got it!! Very Happy

man this thread is hella fun now

Ok, I don't know how or why the subject of my job came up again, but I never lied about what I do. I handle data. I compile it, and do data entry. On good days I get to go out to the line, or I get to go with my coworkers to some really cool briefing. I never described it as a "tech" job, but I guess dealling with computers is kinda "tekkie". Wink

I have described my previous job as being a "Life Support TECH". That job is not related to what I do now, but the TECH in that case is short for "Technician" not Technical. Sorry for the misunderstanding.

I'm not one of those no office windows, lead door, kinda classified spooks. Shocked

You are correct, however. I do work at Tyndall.

Hey Parrothead, something I didn't think of earlier about your VT question. Here's something for you. Check out a pic of the F-105. Note the shape of its burner nozzle.

Then, get a look at the P&W F119. Granted, the 22 doesn't use the bottom "paddles" as dive flaps, but the paddles can work independently of each other. Of course, whatever one engine does, the other matches.

Check out some hush house footage of the 119 in full blower. You'll see what I mean.

However, in flight, when I've seen them use lateral vectored thrust, the pilot will merely roll the jet onto one side, and pull back on the stick. Sucker will swap ends on a dime. Sorta like the Eagle at high G, only more immediate a flight control response, AND it can do it at high speed. Very Happy

Way cool stuff!

Beers and MiGs were made to be pounded!

Pat1, you've got some good points here, but I'd rather have more maneuverability than I need than need more than I have Wink

TC, I've seen footage of the 119 in blower and it's cool Cool

. I never thought of the way it would helping with turn rate Doh

! Great stuff!

Does anyone have a link to the F-119 with blower on?
