F-22 Raptor Vs. F-15 Eagle
I know this subject as probably been discussed to exhaustion, but I'm new
here. Sorry
It's like this (I think?) The F-15 replaced the F-4 and now the F-22 will
replace the F-15. But while I don't think there's any doubt that the Eagle
would "smash" the Phantom I think there's plenty of people who probably think
the F-15 could kick the F22's Ass.
Personally I while I find the F-22 a very impressive machine I must say that
I'm slightly disappointed that the 90's technology (Raptor) is actually
slower and can't fly as high as the 70's (Eagle)
I mean the Eagle can fly at Mach 2.5 and there's reports that it can go all
the way to 100.000 feet for short periods (is this true?)
But the Raptor apparently can't even exceed Mach 2 or 65.000 feet.
Is the Raptor supposed to be a Dog Fighter? It can't out manoeuvre an F-16C,
Mig-29 can it? How many G's can the F-22 pull?
Is the Raptor supposed to be an Interceptor. I doubt it even the F-106
Starfighter can go faster than this slug.
I would appreciate some enlightening
Respectfully

Like some other poster posted, max speed is not combat speed.
No prob...

Uhhh.. no. I do not know anyone who believes that. F22 is FAR superior to F15.

Don't read too much into speed. F15 cannot fly that fast with weapons anyway.
More important is that F22 can supercuise at over Mach 1.5. F15 cannot
supercruise at all. Speed restriction on F22 are based on engine intakes that
limit speed. Intakes are limited due to stealth needs. Just for comparision:
Standard F15C has two engines each putting out 23,500 pounds of thrust.
Each F22 engine produces 35,000 pounds of thrust. Quite an improvement...

See above. Speed is one MINOR factor.

Absolutely. Raptor 1 is the most manueverable fighter in production in the
world today. With thrust vectoring, nothing can match it.
F22 will be the best air superiority fighter in the world.
With the possible exception of the S-37, but I know - thats been beaten
into exhaustion too. I don't want to get a Venik/Yev vs. the world
battle again.
I can just see a MiG-21, which can go over Mach 2, outrunning an F-22. Then
the MiG runs out of fuel, and the F-22, cruising at Mach 1.58, does not have
much competition.
Origionally the F-22 could go faster but when the real one was being built
(after YF-22) they changes to cheaper, lighter, more durable composites.
However, they can't stand as high temperatures as the origional ones (or
titanium) so the speed it limited to Mach 1.8. Otherwise the F-22 would
melt.

Yes, the Eagle has been able to reach 100,000 feet in a zoom climb, BUT that
was a specially modified Eagle known as the "Streak Eagle." The radar was
removed, leaving an empty nose cone. Almost all paint was removed, save a
few markings and the "Streak Eagle" logo on the sides. Only minimal
instruments were present. All underwing pylons were removed. Not exactly
your everyday condition of an F-15. Normal operating ceiling is about
60,000 feet.
JD
Approximately 15 years earlier than the "streak Eagle" record-breaker,
the F-4 had flown to 98,000+ feet.
If the radar had been removed from the F-15 for the attempt, it wasn't
from the nose - which, unlike earlier fighters, contains only the
antenna - not the complete radar package.
It is highly unlikely that any cockpit instruments were removed -
though removing the gun/ammo would result in a considerable weight
savings.
There was a time when all FCF configurations required "slick wings":
no pylons or tanks. However, it was found that pylons reduce the
chance of a flat spin - so that "slick wing" restriction is gone.
The one factor most important to high altitude operations in any high-
performance fighter (dating from the F-104) is the pressure suit
connections for the crew. Without one, 50-60k is about the highest a
man can go inside a normally-pressured cockpit. ( The F-4 had it
removed as unnecessary in the 1972-74 time frame.)
The streak Eagle attempt was an experiment to reclaim the "time-to-
climb" record from the Russians who held it briefly during that
period.

I guess I could have made myself clearer. Anything associated with radar
and weapons was removed. Anything, including instruments. They were trying
to make this plane as light as possible.

Correct.

F-4s were carrying 4 sparrows on all the record flights, as the weight
penalty was offset by reduced drag. ie war loaded.
Skyburner flight profiles were 3 tanks, drop 2 wing near mach 1, drop
center about 1.5, top out at 2.6

Alex,
What are the sources for this? I haven't heard a thing about the
F-22's composite parts limiting its airspeed. As far as I know the main
limiting factor are the fixed engine inlets.

Don't know about F-15, but know exactly about P-42 (stripped
Su-27 for record breaking). All militray electronic was
removed (radar, anit-missile detection etc), plastic nose cone
was replaced with metall one, most of cockpit instruments
were removed too. No lylons, no even underfuzelage tails,
no backward cone with brake-parachute, no airbrake. Thing flew
quite well without them (It actually managed to reach supersonic
in vertical climb). So can be very posible that on F-15 was
all the same.

Well, remember that record breaking a/c is piloted by
extremelly qualified pilot, who for sure can
manage to do not fall into flat span, while regular
fighter is designed for average military pilot.

An still holding it for now :) (http://www.fai.org) Actually it was
opposite, first these records were held by F-15 and later by P-42.

It's always better to lose AN engine than THE engine.
Mach 1.8 with 8 missiles is very good. i don´t think the F-15 can do much
(if any) better. And the acceleration is much more important.
The way I see it the Raptor (F-22) will be the World's first
supersonic fighter. Every previous fighter was a subsonic
fighter, with some having an ability to so a short supersonic
burst. The is vast difference between maximum speed and maximum
substainable practical speed.

I remember reading in Janes Defense that the max speed is Mach 2.4 for
the F-22, what source gives 1.8 ?
In the book "F-22 Raptor" by Motorbooks International (they make a lot of
cool books like "X-Planes @ Edwards" and one about the Aurora by Bill
Sweetman), it says that the composites were changed when the F-22 was being
modified from the YF-22 to more durable, lighter, compostites, but ones that
couldn't stand as high temperatures.

If this is true, then why have expensive materials when the plane, F-22, wont
be able to fly at high speed anyway? The fixed inlets limits the speed. And
it isn't until you move faster than mach 2.5 or so that you start having to
factor in ultra high heat caused by friction. So why have the expensive stuff
that will only hamper not help?
