Combining of TU-104, 110, and 124 into same fleet group.
« on: July 22, 2013, 12:18:55 AM »
Since the aircraft are technically all based on the original TU-104, I think it would make sense, as well as make the 110 and 124 more economically viable if they are combined into the same fleet group. The differences between the three cannot be any greater than the IL-12 and the Il-14 and those two are in the same fleet group.

Any chance of this? For those of us using some of the early soviet jets it would help us to keep these lines open.

Their cruise speeds do not appear to be the same in database, so no then.

Though not sure if that speed data is fully accurate given the age of the models.

Hi Sami, thanks for the reply.

Here is what I got for the aircraft.

Model   Cruise Speed

TU-124   432-469kts      http://en.wikipedia.org/wiki/Tupolev_Tu-124
TU-104   442kts             Game Database
TU-110   431-485kts      http://www.flightglobal.com/FlightPDFArchive/1958/1958-1-%20-%200105.PDF (speeds between 417kts-458kts were given for the 104 here)

It appears that the speed estimate for the TU-110 currently in AWS is based on the highest estimated cruising speed for the 110, it looks like the actual figures would have been closer to that of the 124 and 104. The midpoint for the 124 range is close the 104s current 442kts speed and a similar speed is allowed for the 110's estimated cruising speed ranges.

I would like to add that the TU 110 appears to be a significant redesign (4 engines instead of 2); whereas the 124 appears to be a shrunken version of the TU-104.

There were some changes to the wing structure to accommodate the four engines but the design rationale behind the TU-110 was to try and capture an export market for over-ocean flights that the TU-104 couldn't capture because of its twin engine layout. Beyond that, the improvements to the fuselage were incorporated into later TU-104 models, so besides the engine redesign the TU-104 and 110 have quite a bit in common, and I would also argue that the similarities and incorporated improvements are greater between the 110 and the 104 than the IL-12 and 14 which are in the same fleet group. Performance wise the aircraft were similar, the 110 was just aimed at a market that never materialized.

Could we not set the 124 and 110 to the 104's cruise speed since it is in the allowable limit? Or set them all to 450kts since it is in the cruise speed range for all three? It would mean an increase for the 104 and decreases for the 124 and 110, but those are both set at the upper limits of their ranges already and the standardization would improve their economic viability.

So will this data work Sami? Can a change be made before the TU-110 goes into production?
