what is this sharp protuberance just beneath the tailcone/exhaust pipe? I have seen this on a few of A-134, and almost always on an official government aircraft (Much like "Ekaterinburg" here). Is this a radar or a communication device/antenna of sort?

Thanks in advance

Whatever it is, it looks like the same as the spike pointing forward on the top of the T-Tail..

I'm going with some electronics of sorts...

As in.... the one pictured is pumping fuel TO another aircraft, or vise versa?

Looks like every TU-134 has the same protrusion on top the T-tail pointing forward. I am assuming this may house some sort of HF antenna, and it may be an "option" to have a second one installed at the tail. Possibly for aircraft that spend a lot of time out of normal radio range?

The pointy part on the horizontal stabilizer, I think, may actually be some sort of counterbalance. Seems like I heard that somewhere once. Also, very likely an antenna of sorts. I never really noticed the long proturbance on the TU-134. That does seem to be an electircal deal of sorts. Seems like a good place for something like that. Hopefully someone who really knows will give us the answer.

Remember - the original version of the Tu-134 did not have thrust reversers and used a parachute on landing to slow the aircraft. That would be a good place for one / deploy one.

Another possibility is it could be a defensive chaff/ flare dispenser.

Definitley not

My guess is...

Isn't that what the antennas on the 747-100 wingtips were for?

maybe? I remember hearing that the reason all those old commerical airliners had glass noses is becuase they could be converted to bombers or transports or something in case of war and the nose would then be a required crew member position for something (of course I heard this maaaaany years ago so it could be completely wrong).

I asked about glassed nose cone a while back. OV735 gave some good information regarding this:

About two thirds of the way down the picture shows the tail and this is the caption..

Interesting Tu-134 - with a 'Balkany' (Balkans) long-range communications system in a tail stinger.

It's an HF antenna, a part of the Балканы ("Balkany") radio suite, used on Tu-134s in airborne command post role. Very similar in function to the Gulfstream C-20 of the USAF:

Some of these aircraft have found their way to the private sector, where the radio suite along with the antenna is dismantled.

How many TU-134s were in that role? Do these particular ones have anything else modded for that role: extra fuel tanks, etc..

According to Dmitriy Komissarov's excellent book on the Tu-134, there were approximately 40 aircraft fitted with the Balkany suite. None were brand new aircraft, but converted Tu-134AKs (the K stands for Komfort - for VIP transport, identifiable by the rear entry door on the port side) built between 1979-1982. The conversions took place from 1986 until the early '90s.

All the VIP/government Tu-134's have two additional 600kg fuel tanks in the wing centre section, boosting the range by about 400-500 kilometres. Note that at some point this option also became available for civilian-role Tu-134s.

Hehe, thanks. I grew up with the overflying Tu-134s acting as an alarm clock in the mornings, thus the interest in its details.

Cheers,
OV735
