The only trijets I know of that do not have reverse thrust on the #2 engine are the Dassault Falcon 50/900/7X and the Tupolev Tu-154. The L-1011 and the 727 did have reverse thrust on the #2 engine. As did the DC-10/MD-11.
Judging by photos, I think the Yakovlev Yak-40/42 and the Hawker Siddeley HS 121 Trident don't have reverse thrust on the #2 engine either, but somebody correct me if I'm wrong.

From what I recall, the Falcon 50/900/7X are actually quite the opposite, they have reverse thrust *only* on the #2, while the #1 and 3 lack reversers. The center bucket reverser on the 900 produces a very distinctive wheezing/coughing/backfiring sound on the 900s when it's activated. You're right about the Tu-154 though, just a straight pipe there.
The Yak-40 has a T/R system similar to the Falcons, with the bucket reverser on the #2 engine only. The Yak-42 doesn't appear to have thrust reverse at all. The HS.121 lacks T/R on the #2 engine though.

Quote: What is Tay?
He means the Rolls-Royce Tay engine, used on the Gulfstream IV, Fokker 70/100, and a few re-engined 727-100s.
There was also a Tay conversion for the BAC 1-11 from the same company (Dee Howard engineering), but only two were actually converted. By the time it was ready, not many people wanted the 1-11 anymore and it wasn't suitable for freighter conversion.

We have one 727-200 at my company with the number 2 reverser removed. It has the Dugan Quiet Wing mod with JT8D-15 engines on it. Part of meeting noise compliance was to remove the reverser off of two and put a long stove pipe extension on it. It looks like this:

Quoting Chamonix (Reply 9): Tay must be a river following RR nomenclature.
Only RB (Barnoldswick) and Merlin were the exceptions - hazarding a guess.
RR named their piston engines after birds of prey, so the Merlin is not an exception.
RR turbine engines have a model number and a river name, though the RB211 never got named for some reason. The Tay, for example, had the model number RB183.
The glass isn't half empty, or half full, it's twice as big as it needs to be.

Quoting Chamonix (Reply 11): Would that be a 727-ADV (Advanced)?
We have another -200 with the Dugan Quiet Wing and JT8D-9s that still has the #2 reverser. The -9 equiped airplane used to have -15s in a previous life so it could just be a matter of which engines are on the frame.

Well, as I understand it, the Trents share much (architecturally) with the RB.211, so it kind of sort of got a name... I know that there are probably close to zero interchangeable parts between any RB.211's and any Trents, though.
Celebrating the birth of KELPkidJR on August 5, 2009 :-)

Just curious, what engines you have on your -100, -9's?
