This is a pretty easy one.
What is the fastest speed aircraft in the world? For the sake of argument, lets exclude the space shuttle and any type of space vehicles.
-
Air breather = SR-71
Rocket = X-15
F.
-
Do you mean an African or a European aircraft?
(sorry, couldn't resist :) )
-
What furious said, and with the X-15 at a breezy mach 6.7 :D
-
A crashing plane..
the fastest plane in the world for people inside it.
-
and more faster prop plane at SL before 1968?
-
I think the fastest air-breathing aircraft are the MiG-25 "foxbat" and the MiG-31 "foxhound". I think they can do Mach 3.5+
Yeah but in non air-breathing the X-15 wins hands down.......:D
-
mig 25pd 'foxbat-e': 3.000km/h+, equals mach 2.83 (with external fuel tanks) @ 43.000 ft - "max cruising speed at height: mach 2.35"
mig 31a 'foxhound': 3.000km/h, also mach 2.83 @ 58.000 ft (no external payload) - "max cruising speed at height: mach 2.35"
sr-71a 'blackbird': 3.500km/h, equals mach >3.2 @ 85.000 ft (no external payload) - "max cruising speed at height: 3200km/h / mach 3+"

Think both the Mig 25 and Mig 31 have higher speeds then that, they were both designed intercept the SR-71, the figures I've seen for them says Mach 3+.
Still, SR-71 may very well be the fastest, wouldn't surprise me if it is.
-
SR71 Cruises at mach 3.
She's been seen approaching Mach 4 on multiple occasions :)
The *true* top speed is still very much classified.
The MiG-25/31 was actually built to intercept the nuclear bomb threat (from Alaska and Europe) quickly, at high altitude, and efficently (loaded with the biggest missles the Russians had in the inventory). Basically a Russian Air Force's version of the American F-14 Tomcat (designed to take out the Bear threat at long range and high altitude with her Phoenix missle salvos).
-
109 had and held the speed record for piston engined planes untill 1969. It set that speed record in 1939 I belive.
-
Not quite - if I recall correctly, the record-holding plane was designated as ME-209 and had some superficial similarities in appearance to the 109, butz that was done mostly for propaganda purposes (to show off what a great plane the 109 was). In reality, the 209 was a completely new design that had little in common with the standard 109 (completely new airframe, different wing shape, different engine etc.)
-
ok... here's one....
The Foxbat was designed to intercept the B-70 bomber... the US scratched it and left the foxbat without a mission that a cheaper more easily maintained aircraft could handle. Also, that speed could be achieved by the uber migs... but had to have the engines replaced when it came home
Bring the PBY 5A to Aces High
-
By far and away the SR71 hands down fastest aircraft in the world
-
sr71 is the fastest...from what i know. (not much)
but from what i hear...the F-22 is the fastest "fighter" in the world. (again i dont know much about this stuff)
-
Correct Answer is X-15. The Foxbats werent quite as fast as the Sr71. The Russians had to launch the Foxbats ahead of an incomming Sr71 in order to intercept it. Also, after every attempted SR71 intercept, the Foxbats had to replace their engines.
-
ferkelparade ;) have reason. The plane called 109 R was really a 209 v1. The 209 flyded by Fritz Wendel take 755km/h at April 1939. Wendel said about the airplane"it is a tiny monstrosity ".
-
LW never the less :D
Better go read up on the 209, too bad it never made it in the war, like so many other LW uber planes under development.
-
the f-22 isnīt the fastest, but one of most the expensive (estimated total cost of all 648 planes: >$99.1 billion. the b-2 'spirit' program is estimated at >$290 billion). itīs being build to replace the f-15. apparently the f-22 is 'slightly' slower than the eagle - top afterburner speed is 921 mph for the raptor, while the eagle does 1,875 mph.
the key features of the raptor are: 1.) itīs stealth capability - when the enemy canīt locate your plane, there is no need to go mach 2+. 2.) manoevrablity. the f-22 is extremly agile with a roll rate of about 100ø/s roll rate at 120 knots and a cruising speed of mach1.58 .
-
Wilbus: I read somewhere that there were experiments to use the 209 in the war, but nothing ever came if it...anybody know more about that?
I don't know how the 209 would have performed as a fighter, it was basically constructed to fly in a straight line (just look at the double rudder), don't know what that would mean for roll rate etc :)
-
Theres no need for the F22 in my opinion. Better ground attack aircraft are needed. Also, as a former Green Berete colonel said on CNN, billions of dollars are being spent of fighter aircraft while ground soldiers still use antequated equipment (such as extremely bulky and heavy radios).
-
Hey Ho Ferkel :)
Read up some more on it, it was designed as a high altitude high speed fighter, and was suposed to be the a fighter plane of its own, however, the TA152 beat it and the 209 was canceled when only a few prototypes had flown.
Allso, do add to the jet discussion, you guys are foregetting some planes ;)
The Swedish JA37 Viggen (JA = Fighter Attack) is most likely amongst the fastest fighter planes, it has never been run on full power (pilots aren't alowed to during peace time) and yet, they've never made it stop accelerating, they've had it up to speed above mach 2.5.
Another key factor not to run it on 100% throttle is that, since it is a defencive plane, it haven't got alot of fuel, and on full throttle its fuel last for 5 minutes.
-
It was? My sources tell me it was specifically designed for the speed record flight, the attempts to use it as a fighter seemed to be a last-ditch effort mainly because the design was already around, and it really didn't turn or roll too well, so the idea was canned quickly...bbut I'll gladly learn more about it if you can provide some sources :)
Sorry, can't contribute much to the jet discussion, if it doesn't have a prop, I don't wanna fly it (that's a question of style :) )
-
Hate to burst your bubble gents with X15 - any shuttle whether US or Russian beats measly 6-odd Machs with something like 5 miles/sec (24-odd Machs if my maths work;)) max speed needed to leave Earth's gravity well. It's got wings hence it qualifies:D:D
What a dummy - just read the FDIron's post properly - sorry:)
-
IMO X-15 isn't exactly an aircraft. It achieved its top speed at 250 000ft which is pretty much space to me. A book that I have tough states it as "high speed high-altitude research aircraft". But a vehicle with rocket motor as its primary source of propulsion is not an "aircraft" to me. IMO X-15 is "the fastest man made vehicle which is steered by human when in its top speed".
So, IMO Locheed SR-71 Blackbird is the fastest aircraft in the world as many sources state it is.

Wilbus, Ferkelparade, hope this helps:

I have seen drawings of the 209's on the net, but I'm too lazy to search now :p
Greetings

SR 71: Able to take off from ground BY ITSELF, fly around for a long time and land. It used wing lift and is re-usable.
X15: Lifted up in the air by a bomber (b29 afaik), dropped and the 1 million horsepower rocket is ignited and burns very shortly but enough to reach mach 6.7 before things get to hot.
X15 is no plane but a rocket with stubby wings, it can't take off unaided and any ultralight plane will get you further given enough patience :)
The Spaceshuttle is a Spacecraft with the ability to GLIDE (can hardly call it flying) back to earth and land. Gimme a brick with a firecracker rocket attached to it and while sending it from space to earth will also get you faster then the SR71 but still wont make it into a plane :p

Could the Space Shuttle be classed as an aircraft, and if so, how fast could that do?
Nexx

I seem to remember reading an article with a SR-71 pilot and when they asked him what would they do if the soviets beat their record the pilot replied by saying that they would go back up there and press down the accelerator a little more. [;)]
-
What kind of endurance does the SR71 have at Mach3? Anyone have any numbers on the range of the Blackbird?
-
AFAIR the endurance of SR-71 was something like one hour in full speed and 1,5 hours @mach 3. Not much in hours but if you count miles....
-
Jan - A little tidbit on the F-22.... it is capable of maintaining Mach 1.5 for extended periods of time, unlike our current genre of fighters. That is its BIG claim to fame, and the reason it was chosen over the F-23 which was more maneuverable and has a higher top speed.
As for the fastest aircraft, I believe it to be the Aurora aircraft. Even though the US Airforce denies it's existence, enough photographic evidence exists now for them to use the "no comment" reply when asked. It (An unidentified air target) was recorded by ground radar in Wyoming as doing Mach 5+ Pretty interesting.
:p
