Why The Scorpion Tail On The Tu154?

Sun May 08, 2005 6:45 am

I have seen (and photographed) the Tu154M at LHR several times (Pulkovo flies it there).

I've always wondered why the Tu154's tail has the sharp, pointy "scorpion sting" on its tail (the thing that points forward from the tail).

Anyone know why?

On the Tu-134 that houses a radio so I'm 99% sure that's the case here. Same with the B707(although it's much sharper).

Yes...that would be the HF antenna!!!
On Some 707 it can also be found on the wingtip....!!!

Another reason is to house the actuators for the stab (similar to the DC-9 series).
And in military service (what both the 134 and 154 were designed for) ECM equipment and possibly other countermeasures can be easily placed in a pod like that, easier than having to dig inside the fuselage for space to string wires for antennas.

The Tu-134 "balkany" airborne command post has the special gear at the end of the fuselage. Other special versions do include fairings of sorts on the fuselage but they dont have anything but the radio antenna in the "scorpion sting".

The Tu-134 "balkany" is a tactical airborne command post the name coming from the Balkany secure HF communications suite that it is fitted with. The 'sting" in the back is identical to the "scorpion tail" on the top of the fin. Also features an extra 4 blade aerials(one on top of fuselage, top of fin, two under rear fuselage). About 40 glass-nosed Tu-134As were converted to Balkany standard and they seat between 26-31 people in VIP configuration. Eventually after the collapse of the USSR some of the Balkanys became obsolete and were reconverted back to passenger configuration just like this one.

Notice how it's "chopped off" in the back
