Sat Oct 20, 2001 10:47 am

what are the visible exterior diffrences? how can i identifiy one over the other? also, i read that sometime during the production, they witched from clamshell to target type thrust reversers, what do these look like?

thanks

You really can't- not from the outside away from the plane. The only way I can tell is the different trailing edge flap assymetry protection system on the rear bulkhead of the main L/G wheelwell. Every 737-200 "basic" I've worked on had target type T/Rs, just like our "advanced" ones.

Advanced 737-200 was introduced in May 1971.

Physical dimensions wee the same as the basic B737-200.

The Adv version incorporated aerodynamic improvements, automatic wheel brakes, more powerful engines & greater fuel capacity,gross weight & range, enabling the 732adv to operate from short runways as 3600ft.

Quiet engine nacelles were an option.

15% improvement in payload.5% reduction in fuel consumption.introduction of special sealents,& enamelling of major portions of the fuselage structure for corrosion protection.

Advanced composite technology was used as graphite/epoxy elevators, rudder & ailerons.

do the engines look any diffrent? Also, were there any aerodynamic improvments beyond the flaps?

Early 737s had auxilliary intake doors like 707s and early 747s.

Early Lufthansa pictures show a different nacelle rear end design, possibly the original thrust reverser config??

Early lufthansa pics you describe probably refer to the B737-100,The -200 had a tailpipe installed between the Engine & T/R.
Engines on -200 & -200 adv look same exterior.
Thrust rating vary though.
The -200s had the JT8D-7/7A,9/9A.
The -200adv had JT8D-15/15A,17/17R.

As far as the engine doors on the previous -200 basic models are concerned, you might do a search for the term "sucker door" (or doors), as I'm pretty sure it's been discussed before.

The easiest way (for me, anyways) to distinguish between the 737-200 Basic and the 737-200 Advanced is to look at the leading edge of the wing.

This engineless bird is a "Basic" model (line number 110), and you'll notice the edge of the leading edge krueger flap doesn't get very close to the edge of the fuselage. Look at the edge's location in reference to the landing light at the wing root.

Compare the above photo with two below of an "Advanced" version. You'll notice that this leading edge krueger flap now extends all the way to the edge of the fuselage. It was a major aerodynamic improvement over the "Basic".
