737 replacement??

sparkplug · Jan 11, 2009

I'm sure you've heard Boeing is researching a 737 replacement. What is everyone opinion and what route do you think it will take?

I've so heard Airbus is looking at a A320 replacement but I doubt it.

That plane has quite a lot of users.

I don't care as long as a hot stewardess keeps bringing Martini's

Chris, these days they are called flight attendants, usually they are draconian and often they are more or less male. Sorry for being such a downer. I'm pinch hitting for Steve S.

The plane sure does have a lot of users. I'm sure Southwest is pushing Boeing for such a development. I'm sure it will be a development off the 787.

I know they are probing their users for requested inprovements. I wouldn't be supprised if you see a even newer NG 737 type now utilizing composites and whatever the latest and greatest CFM can come up with. The physical design of the current NG737 is a huge longstanding design after years and years of refinement.

Composites are the wave of the future, but I'm not positive you will see any huge airframe design change from either the Boeing or Airbus camps.

Thanks for covering for me mori.

Yeah, the 737 airframe is a tried and trued airframe. I too believe there won't me a massive departure from the current airframe. I imagine Boeing is going to use composites where ever they can. I would like to see more power plant options. I've never been a CFM person. I hope they change the the flight deck too. That overhead is ancient! Fly-by-wire ect. and please keep the eye brow windows!

The sad fact is that Southwest will be/ is on the advisory board. They had a HUGE share in the revisions to the current 737NG. Interestingly enough, they pushed Boeing AWAY from FBW, and I don't know why. Their primary objectives will always be simplicity and commonality.

The newest version will surely be FBW and composite. I'm not a fan of CFM either, but they keep getting huge bids from Boeing/Airbus, not to mention military contracts... you can't argue with success.

About the eyebrows... I think they look sweet, but the last 737 pilot I talked too said they were happy to see them go. They aparently just added more glare and not much inproved visibility.

Simplicity and commonality is usually the goal of every airline and is understandable. FBW and integrated controls would be beneficial.

It's about time another SWA plane overran the runway because the pilots failed to armed the spoilers. In the 320 if you forget to do something in set up for landing the plane will let you know.

US Airways signed a HUGE contract with IAE through 2032 for their engines. I mean I love the 737 but after flying the A320, the 320 is a much better airplane IMO.

Hopefully the new one will have cruise performance like the climb performance. "once it gets to cruise altitude it parks"

How so? We see typical cruise speeds between .77-79 (even transcons), and most will sprint to .80-.81 if asked. All the narrow body Airbus products are about the same, if not maybe .01 faster on average. Only the heavies cruise above .80 routinely.

They do climb like a bat out of [censored] though... a commercial jet go from wheels up to FL410 in 16-20 minutes is Learjet territory...

Not really...they are the same HOT ones from the 1970's & 80's just still working there....

I think I've encountered some that might have been from the 60s. Or at least they look old enough, maybe all the flying has taken a toll on them.

I flew on World Airways a few years ago and I'm pretty sure the entire crew was retirement age in the 1990's. The service was outstanding though.

Cujet · Mar 25, 2009

I was just reading in AIN about the engine bypass ratio and cruise speed. If you folks don't know, the higher the bypass, the lower the thrust at altitude for a given T/O thrust.

That means the new generaton of large efficient engines will likely have cruise speeds hovering in the high 0.7's.

Un ducted fans may make a comeback with a cruise around M 0.70.

Steve S · Mar 26, 2009

I though the high bypass fans were to reduce fuel consumption?

sparkplug · Mar 27, 2009

Yeah bypass turbofans produce loads more power than turbojets not to mention MUCH quieter and use so much less fuel.

I don't think a 737 can out-climb a 757. 757s climb like rockets. The engines are about twice as powerful. I was on an ATL-SLC flight last week when ATL was getting hammered by bad weather. In fact it was closed for about 20 minutes due to extreme weather. When we finally took off it was bumpier than a mofo with the thunderheads all over the place. That pilot kept that thing in a steep climb up to about 20k feet to try to get above it. A brief pause at about 20k was followed by another steep climb up to over 30k to finally get us out of the weather and into sunshine. I don't think anything non-military can out climb the 757.

Ride one out of John Wayne/Orange County and check out the "noise abatement" takeoffs. The climb nearly vertical until it starts running out of airspeed.

With the 787 and the 748-8 on their plate, the 737 replacement program will not be started until at least the middle of the next decade. Look for entry into service around 2020.

Plane will be CFRP like the 787 and will feature FBW, a wider fuselage, normal landing gear (not so close to the ground like now) and a choice of at least 2 engines, the PW geared turbofan and whatever CFMI comes up with.

737 replacement??
