Gulfstream question...

[doublepsych]

Can anyone share some simple, easy ways to tell the various Gulfstream models apart from across the ramp? I can see subtle differences, but don't know which model is which. Thanks for the tips.

II's are all about subtle differences

II's and III's : 5 windows

All IIs have a pair of small windshields (one on each side of cockpit)
II-no wingtips
IITT- Tip tanks
IIB- angled wingtip (not curvy at the base of the tip)
II-SP - "bent" wingtip at base; 3 small vortilons on each leading edge.

III's look like II's, but no small windshields like the II's

IV's and V's have 6 windows, V's have a cabin "stretch" (dead giveaway).
V's are easy to differentiate. Just look at the bucket reversers/clam shels and the buckets arent silver .

and of course the new V's (500/550) have 7 windows.

lets see, what did i miss?

And I will add that 450/550 don't have windshield wipers...

The bucket reversers on the G450 are very similar to the GV/G500/G550 so is easy to confuse, just count the windows (6 G450, 7 G500/G550), but the engines are smaller, the G450 door is placed about 3-4 feet away the cockpit (the same as the G500/G550 door), the GV door is placed at the same place as the GIV door.

The G300/G400, the G350/G450, and the G500/G550 are virtually the same plane (just less fuel capacity and some internal devices deleted are the diferences).

and g3 has straight sloped nose from above front windshield to tip of nose....where the g2 & g2b has a bit of a kink in it at the bottom of windshield

HEHEHE.....semperfido said, "Kink"!

 

[semperfido]

ooops

love them Blowers

AND -

Ya'll don't forget the difference between a DC GIII and an AC GIII - the AC version has a polished aluminum fairing around the APU exhaust (like the -IV), the DC model has only the APU exhaust - no fairing.

A small tidbit that's won me a beverage or two...

And for those stuck babysitting an APU looking at only the LH (non-APU) side of an AC-III, it doesn't have genereator cooling intake scoop on the bottom of each engine cowl. No generators to cool!

The easiest way to tell a GV series aircraft from any other Gulfstream is the "notch" in the vertical stabilizer. It's about 3/4 of the way up the tail and it's just a little change in the rake of the stab sweep. It looks alot like an MD-87.

Absolutely the easiest way to tell them aprat from any of the others at a distance. Quite a few G-IV operators have taken to painting the revereser buckets now and they're pretty hard to tell apart from a GV at a distance.

lets see, what did i miss?

G-I has propellers!

 

[need2fly]

G-200 has boots

 

[semperfido]

G-200 has boots

i think they mean real gulfstreams and yes i know you were joking. i just couldn't help it

The 450 and 550 have EVS window under the nose which is easy to see. Also they have the new flapper type outflow valves.

 

[efc]

Or should I say Thrust Producing Outflow Valves.

 

[AA717driver]

Also they have the new flapper type outflow valves.

"...flapper type..."

Man, GVflyer is gonna come down here and b!tchslap you into tomorrow! TC

 

[Duderino]

Can some one explain this new type of outflow valve? Por Favor, Senor.

 

[AA717driver]

Dude--It's a square hole with variable "pitch" louvers that open and close based on altitude but they direct the outflow aft so the engineers claim a small gain in "thrust" as a result. Great marketing tool.TC

550s are slick

Actually, it is more about a reduction in drag then an increase in thrust. The disruption in airflow caused by the outflow air hitting the airstream at a right angle is more than you would think. By angling the outflow air, they were able to reduce the drag considerably (for such a small change).
