The F/A-22 is now
operational, with
several wings
already flying in
the Air Force. The
JSF-35 'Lightning'
is fast approaching
operational, and can
do much more than
the F/A-22 -
including literally
stopping in mid-air
from near
super-sonic flight.
The Su-27 / Su-31
'Cobra' maneuver was
essentially a
'one-trick pony'
maneuver. The
F/A-22, and
especially the
JSF-35, can stop and
eat a Sukoyhan doing
the 'Cobra'
maneuver, plus do so
much more.
And, as pointed out
by some ex-F-4
Phantom drivers, ANY
of these maneuvers
in an F-4 Phantom
would have resulted
in stall/fall/spin.
H. Ownby (USAFA
'69) Fast
(super-cruise*) and
stealthy, and
integrated avionics
are cool, but what's
really impressive is
the F/A-22s low
speed stability and
maneuverability. In
the late 40s and to
early 60s
aeronautical
engineers were going
nuts on how to shape
intakes to handle
both subsonic and
super-sonic air
flows, without
stagnation or
compressor stalls.
Supersonic in itself
was a big challenge
because you had to
use shock waves to
slow the intake air
mass to sub-sonic
before it hit the
compressor blades,
or they would stall.
The engineers
figured it out, but
the solution was
keeping a lot of air
going in the front
end to make sure all
the hot air kept
going out the back
end. As you watc h
this M ach 2
airplane suspend
motionless in air
and do tail slides,
be aware of the
truly amazing
performance of the
engines and intakes.
Some used to think
the Su-27 / Su-31
'Cobra' maneuver was
the epitome of 3rd
to 4th generation
fighter
maneuverability.
That snap maneuver
doesn't hold a
candle to what this
two-dimensional
vectored-thrust
fighter with fat
independent
horizontal stabs can
do at low speed.
There must be far
more tricks up its
sleeve in the high
subsonic dogfight
speed range.
The video is about 5
minutes long, but
the last 30-40
seconds are
priceless.
Note also, that the
RAPTOR does a
complete 360 degree
turn in less than 20
seconds !
ACC recently
approved the Raptors
new DEMO profile.
This was the first
show. Five minute
video.
Watch the elevators
of the airplane in
this demo. They work
independently. It
also has vectored
thrust.
*Supercruise: The
F/A-22 can sustain
supersonic flight
without the use of
fuel-gulping
afterburners.
