It's my half-birthday!
I seriously have never thought about my
half-birthday in my life until I was thinking
'I need a title, hey, look at the date, my
birthday is six months away!' Looolz.

| SU-27 jets doing the "Pugachev's Cobra" |
 |
Turn back on a full speed and do shot back !
Dream for any fighter pilot.. 99 % of jets
in the World will be destroyed doing Cobra
manoeuvre. But SU family planes do it easily
and beautifully.
It is Russian engineers, scientists and
pilots!
The "Pugachev Cobra" is a fighter aircraft
maneuver. The maneuver is so named after the
Sukhoi OKB (design bureau) test pilot Viktor
Pugachev, who first performed the maneuver at
1989 on SU-27.It is a demonstration of the
pitch control authority, high angle of attack
(AOA) stability and engine/inlet
compatibility at high angles of attack of the
aircraft. Maneuvers that are related to it
include the "Cobra Turn", and the "Frolov
Chakra". Until recently, the German
Luftwaffe have performed the maneuver with
Cold-War era MiG-29s (for example at the air
show for the Royal Dutch Airforce at
Gilze-Rijen Airforce Base, in 2002). The
Eurofighter Typhoon should be able to perform
this maneuver, as long as the engines stay
lit. Vehicles known to be able to make the
cobra maneuver are the Su-27 'Flanker' family
(from horizontal flight), MiG-29 'Fulcrum'
(from a 30 degree up angle), the F-22 (from
horizontal flight) and the F/A-18E/F (from
horizontal flight). Thrust vectoring aircraft
(such as the Su-30 'Flanker', Su-37
'Flanker-F', Su-47 'Berkut', MiG 1.42, F-15
ACTIVE, F-16 MATV/VISTA, and NASA's X-31)
should be able to perform this maneuver more
easily, though note that the air intake still
needs to be able to handle the air inflow.
Russian fighters, designed for high
maneuverability, are known for performing
this maneuver at air shows for dramatic
effect. The maneuver consists of the pilot
disengaging the alpha limiter and pulling the
aircraft to a 90°--120° angle of attack,
then back down to zero. In a properly
performed Pugachev's Cobra, the plane
maintains a straight and level flight
throughout the maneuver.

| Chopin, Nocturne, opus 27 #2 |

Go to http://www.musanim.com/watch/ for more
about this movie and others.
Info for this video
Piano music by F. Chopin, with harmonic
interval types shown with colored lines.
This type of display is available as the
"YARN" display in www.musanim.com/player/
Note: If you have trouble with sync or audio
quality, go to
www.vimeo.com/user=musanim/clips and download
the original (m4v) version.
I made this rendition in the early days of
MIDI, by laying down left hand and right hand
tracks individually, not in real time.
BTW: the color key at the beginning is
incorrect: m2/M7 are red, the same as A4/d5.
