Gulfstream question...

Or should I say Thrust Producing Outflow Valves.

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

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

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).

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

I believe they call it a Thrust Recovery Outflow Valve...

Yeah, what he said... TC

Thanks, all, for the info...

Thrust Recovery Outflow Valve

This is from our press release.

The TROV recovers wasted energy by reusing air released from the cabin outflow valve, which controls cabin pressurization. By directing this air into the free air stream, the system boosts takeoff performance, speed, fuel efficiency and range.
