B-47 JATO takeoff

[DevilMaster]

A camera should've been mounted on the plane to show the JATO units in greater detail.

[chokedad]

very messy

[kolbpilot]

I'll bet B-47 pilots enjoyed those kind of takeoffs.

[poldago]

While in UK from 1957-1958, the B47 was on alert for the cold war. The British V-series aircraft were being test flighted at the time. With heavy loads on takeoff, water injection would produce lotsa black stuff, but it got the job done.

I did manage to watch many a take-off, all in the name of PEACE and it musta worked..

[BIGBalls136]

Yuck all i know is that American engines have always been produced more carbon and therfore suck compared to you geussed it RR engines... always will be the case.

[AgentJayZ]

@BIGBalls136 Hmmm, RR Trents are trying to repair their reputation for safety right now...We work on the older stuff from both GE and RR in our shop. Right now I'm working on a pair of J47s, one of which was for a B47-B.

[asshatnowhere159]

damn did that plane run on deisel!??

[Snigglesnock]

looks like its crashing lol

[Cars5678]

air polluter :(

[geinman1287]

The original B-47 RATO was built in the fuselage. 19 bottles. The later ones were in droppable rigs slung under the plane just aft of the rear gear. 20, 30, or 33 bottles.

[ratty860997]

My god look at the flex in those wings.

[fernfeyes]

@ratty860997 ..good for bending it around corners.

[EMT308]

You know it is going to hell fast if you need to get your bombers off the ground that fast. Thank God they never had to launch for real.

[bestamerica]

this B-47 is okay,,,

B-52 is the best plane ever

[Coffeeandasmoke]

Anyone worried about a little pollution must cease breathing immediately...

There. Problem solved.

[journeyquest1]

This is the plane that lost a hydrogen bomb off of the coast of Georgia, USA. They still havent found it.

[oisiaa]

This is one of the most beautiful things I have ever seen. That black smoke cloud makes me grin from ear to ear.

[manhenk]

did he died??

[yuna238]

is that wing tip suppose to wobble like that?

[Eirik36]

@yuna238 b/c the wings were so thin they wobbled like that, they had to strengthen the wings to add the external fuel tanks, but it still wabbled

[yuna238]

@Eirik36

thats not suppose to happened. When wing tips wobble it creates airflow distortion. Ever see what happens at the end of wingtips?? Vortex.

Sure adding external fuel tanks. But with the amount of fluctuations in the wind, it actually decreases the efficiency of flight duration. So adding extra fuel tanks may increase some more miles, but with a stable wing, that extra fuel tanks can go even farther.

[Eirik36]

@yuna238 i know its not supposed to do that lol, the wings were to thin, but it got the job done

[yuna238]

@Eirik36

was this a test flight for JATO rockets, or actual mission?

[Eirik36]

@yuna238 The RB-47H first entered service in August 1955. Over the next decade, RB-47H crews of the 55th Strategic Reconnaissance Wing (SRW) flew thousands of dangerous "ferret" missions. Flying in radio silence at night along -- and sometimes over -- the border of the Soviet Union and other communist nations, RB-47Hs collected essential intelligence about the size and capability of Soviet air defense radar networks.

[datzfast]

@Eirik36 my dad use to do that in the 1960s in a C 130 in civilian clothes no ID no tags no bags. of course for all i know he was chasing Bait planes. He said sometimes they put the plane in a dive at maximun thrust and held it there at maximun thrust untill he thought the engines would melt of the goddam wings. on the way out.

[jkk20]

polution at its finest usa number 1!!!!!!!!!!!!!

[MsFarQ2]

Shouldn't the title of this vid be 'B-47 JATO' only?? You're basically saying, in the title, 'B-47 Jet-fuel Assisted Take-Off takeoff'! Know what I mean? Kinda like saying 'ATM machine', what your really saying is 'Automatic Teller Machine machine'! :-)

[TsurugiJiri]

"Oh noes, it da internets gramma' po-lease! Runs away, runs away!" (Moreover, one could have a video featuring the B-47's JATO units (fitting, ground tests, overview, detail, etc.) without featuring an actual takeoff, so I would maintain that this does indeed have a grammatically valid title. By the by, as we're on the subject, the contraction of "you are" isn't "your". Double and questionable punctuation and the use of emoticons also earn you grammar demerits. So there, ;p )

[MsFarQ2]

By the way, no, we were not on the subject of punctuation. So get your facts straight. It was merely a observation, which I thought humorous. I'm still right... by the way! (Emoticons are a valid form of communication on the 'internets', they portray one's emotions so as to convey an air of not being so serious, something which you obviously failed to comprehend).

[TheCannonofMohammed]

The United States crows about being green (Al Gore) but then spews pollution when taking off to bomb Islam. Hypocrites.

[TsurugiJiri]

Yep. Our mighty fleet of Strategic Air Command B-47s are on their way to bomb Mecca and Medina right now. And Gore's putting you on his target list for your imprecations, too, because he invented the Internet, you know. He's going to make all the compact fluorescent lights in your vicinity explode. You and all of your nine-year old wives will die tragically from mercury poisoning. Such a pity.

[Closeoutracer]

You're complaining about the polution of a plane that was designed over 60 years ago.

The Boeing B-47 was built between

1947 and 1956.. and was mothballed

in the 1960's before the idea of

being "Green" had ever been thought of. I heard most Islamist still wiped their

ass with their left hand instead of using

toilet paper... I guess your fingers must

stink when you're praying... kind of hypocritical to pretend like you're reverant when you're sniffing your own shit.

[TheJomogogo]

God that's the best put down of that greasy religion I've heard....being reverant while sniffing their shit.

[myvwsRrusty]

@Closeoutracer I kind of like, no, strike that I DID like those remarks!! Excellent!!

[78720]

thats sad. The B47 is a very well built aircraft. i dont give a dam bout goin green anything that is loud big and fast is alright for me

[potatoradio]

Yes and soon we shall break out the Wright Brothers flyer from the Smithsonion . It is all part of the plan to sink every islamic city. Ok so we loose La, San fran, ok no big loss maby SF, NYC, 'Nawlins,Seattle. ya caught us oops.

[datzfast]

@TheCannonofMohammed Barak Hussein Obama won the Nobel peace price

stupid

[TheMohawkNinja]

@TheCannonofMohammed We call ourselves green, because we are creating many fuel efficent cars along with aircraft engines. So while yes it's not perfect... we are making very "green" engines, which are less polluting than many other modern engines.

[tomperanteau]

@TheCannonofMohammed <--- Look. Third-world Muslim trash. Muslims suck.

[mrskyking737]

Technically, all rockets are lifted by a jet of expelled fluid, thereby making them jets. Look up jet-propulsion in the dictionary, and you'll see what I mean. Even an octopus uses jet propulsion, and they hardly have turbines... The term JATO is correct, and the also-correct RATO simply describes them in more detail.

[Acornoa]

jato arnt they more rato than jato?

[TsurugiJiri]

See earlier discussion...

[JGMagoo]

B-47 was one of the most BEAUTIFUL airplanes ever prodced...IMHO!

[rbrooks2007]

That is a pretty flat take-off with RATO. As a kid I used to see them end up at near the same angle that a Vulcan could do, when I lived near Brize Norton which was in SAC hands back then.

[baseballbmxer]

for some reason it doesnt look as good as the blue angels fat albert with JATO

[Arcmate]

The B47 was a good try but nowhere near as good as our V Bombers.

[TsurugiJiri]

With initial flights six and eight (Valiant and Vulcan/Victor, respectively) years later, that would hardly be surprising. Even the Canberra postdates the B-47 by a few years. The B-52 would be more of a contemporary of the V-Bombers. It's like comparing the B-47 and the Lancaster, time wise.

[oisiaa]

If I ever hit the lottery big time, I'm going to buy one of these and return it to flying condition. This is my promise.

[TJDOZIER1]

Oops, Thats a RATO take-off not JATO. Its a commonly used misname. JATO is Jet Assisted Take Off, hard to have that on a aircraft with 6 jet engines. JATO was used on the B-36 Peacemaker and was the outboard jet engines used to produce additional thrust for take-off and climb out. They were then shut down in flight. Most people call it JATO even though it is ROCKET bottles attached to the aircraft to assist in takeoff. Thus RATO Rocket Assisted Take Off. The B-47 was a beauty to see.

[TsurugiJiri]

"Most people" in this case would include the U.S. military services, where the term "JATO" apparently originated, and hence my usage herein. While as you denote, this is in fact a misnomer, due to the use of rocket bottles, it is nonetheless the most widely accepted usage.

[TsurugiJiri]

Furthermore, the B-36's jet engines were not used exclusively for takeoff, they were also used to increase airspeed over the target or while under interception threat. Moreover, the first 85 B-36s were built with no jets whatsoever, and still managed to get airborne. The term "JATO" was never applied the B-36's jet engines, because they were an integral part of the aircraft and its operation. Nor, to be snarky, was the single NB-36H referred to as "NATO-equipped".

[TJDOZIER1]

I agree,

It is commonly used as the descriptive term and did begin as a mlitary acronym and was started by the RAF. I was Just pointing out the difference, not trying to be critic.

[rudeboyzero]

Well, a rocket is also a jet, isn't it.

It's not a turbojet, but it's still a jet... a jet of hot gases shooting out of a nozzle.

[TJDOZIER1]

A jet engine needs an exterior source of oxygen with a minimum abmient air pressure to operate and a rocket engine provides its own oxyidizer. A jet engine will not operate in a vacuum but a rocket engine works perfectly fine in a vacuum. A jet engine has a whole lot of moving parts and operates on the pressure provided by the moving parts, and a rocket engine just has pumps and servos. So there are some considerable differences between a jet engine and a rocket.

[rudeboyzero]

I know how a turbine works and I know how a rocket works. I've got both of them in the basement. So I know perfectly well what the differences are.

But the force generated in both engines, is generated the same way: by expelling a high velocity JET of hot gases.

So the method may be very different, but the effect and end result is the same: generating thrust by expelling a jet of gases.

[TJDOZIER1]

In that perspective I agree.

[TJDOZIER1]

I cant resist a good discussion, so; that also depends on weather we are talking about an axial flow turbojet engine or a hi-bypass turobfan engine to doesn't it. As the hi-bypass turbofan engine produces a significent percentage of its total thrust output from the fan section which by-passes the interior sections of the engine, and thus produces thrust without a JET of hot gases.

[rudeboyzero]

Well, that's why it's called a turboFAN and not a turboJET, isn't it? ;-)

On a high-bypass turbofan, the turbine's main function is powering the fan. Very little (but still some)thrust actually comes from the gasturbine itself.

[TJDOZIER1]

Yes, depending on the engine type and manufacturer design, turbofan engines produce between 70 and 90 percent of the total thrust output from the fan section, and thus produce thrust without a jet of hot gases. (My dad was one of the original GE reps for the first GE turbofan engine TF-6/CFM-56, back in the late sixties, early seventies)

[cornskid]

it could still be called a jet just not as hot

[russbug1]

wow nice wing flex

[granskare]

great video! i once worked with a guy who was a navigator on one of these planes. Must have been a real kick :)

thankx!

[artieroo]

The only problem I see to that JATO/water injection takeoff is that you've got to wait for the smoke to disperse until you can use the runway again.

[coldwar2008]

i wish we still used them :( imagine we did they weould look all updated and grey and modified like the BUFFs and have glass cockpits lol

[tisoy909]

What are you talking about?

[nubbie1944]

Damn, I saw a picture of a mock up of a B-47 in modern USAF scheme, pretty cool, wish I could find it.

[morbidfrost]

Pretty plane I love the 6 engine layout.

[KirbyKite]

Flew 'em for several years. The wings could flex total of 18 feet at the tips. Made for soft ride. Faster than a B-52.

[jakobole]

What was spool-up time on those engines?

[oisiaa]

Stunning! That wing flex was impressive!

[guspech]

ranks right up there with a kc135. as far as a plane to look at. awsome

[oisiaa]

The KC-135 will always be the most beautiful aircraft to ever fly!

[usaalways]

Ummm...may I ask what is so beautiful about that flying gas can?

[originalbrownirish]

that must smell good

[SmiertSpionem]

Is it me or were those wings flexing to a scary extent?!

[BaphometKnows]

No, that is normal using lightweight titanium based alloys for structural rigidity/flexibility. Steel is too heavy and eould snap due to its inflexibility

[SmiertSpionem]

Aha, makes sense.

[lewismedlock1966]

the prettiest american bomber ever built
