I have transfered the PT work from my old WIN 7 machine to my new WIN 10 machine by copying my entire FS 9. As the PT needs some changes in the FS installation, I dont know if it would work installing a PT "airplane" without the original self-installer. What is lost is the wealth of information in the PT Forum, which was very helpful to master these complicated simulations. I hope I can remember still some of the answers I and others had given there, if somebody wants to know something.
The real Tu-154s (the B2 and the M) for Western aviation buffs looked like a copy of the B 727. As with other Soviet airplanes basic design decision dictated by mission, airport development and available engines led to airplanes superficially rated as look alike or copies. But transport category airplanes with 3 engines back, clean wings with efficient slats and flaps came to life as: Boeing 727, Hawker Siddeley Trident, Tu-154 B2, Tu-154 M, Yak-40 (no slats on a straight wing), Yak-42, Falcon 50 Falcon 900
All these airplanes less the Trident could deliver excellent short field behavior, the Soviet designs were capable to operate from non paved runways and could navigate over long distances without radio navigation facilities, over territories with big magnetic anomalies and polar regions.
The most successful design of the 3 engines rear mounted design was the B 727 (1832) followed by the Tu-154s (1026) and the YAK 40 (1011) by airplanes built . The safety record calculated in hull losses for the B 727 is 6,5%, for the Tu-154 6,7% for the Trident 9,4%, for the Yak-40 12 % and for the Yak-42 4,9% .
Means the Tu-154 for its time was as safe as a B 727 much safer than a Yak-40 and safer than a Trident.
In comparison with the B 727 the Tu-154M was bigger,heavier, could haul more and fly farther than a B-727-200 ADV. The fuel burn of the M version was better than for the B727-200 ADV but the earlier Tu-154 B2 burned much more fuel: Tu-154M 7,4 l/km Tu-154 B2 12 l/km and B 727 ADV 8,5 l/km
In itself the Tu-154s were remarkable designs apt for their country, its climate and their role.
Project Tupolev delivered a simulation offering what no other flight simulation in combination did:
The aircraft's systems work like in the real thing, the navigation systems are so and work so like in the real airplane, the flight dynamics and feeling of the controls are near to the real airplane as real Tu-154 pilots were part of the design team. The procedures follow the real airplane so much, that PT- Tu-154 was used to prepare real pilots for their simulator training.
AND: It was freeware
Kind regards Walter
P.S.: For the development of the Tu-154 the end of Tu-144 was essential. The Soviet Union felt they had demonstrated they could build a supersonic airliner but the internal necessities of the Soviet Union got priority over the "prestige project". So their best designers under Alexander Shengardt were employed to work on the trijet.
According the "book" maximum operating speed was M 0,88 above 10.300 m. For best range the speeds of the 154M were much lower:
High speed cruise was done at M 0,87 burning in practice over 5000 km 28,3 tons of fuel same distance in best range cruise needed 27,4 to both at FL up to 390 (11900m) the maximum permitted altitude. Going high speed cruise one could save over 5000 km around half an hour flying time.
So the speed and fuel burn differnces over western airliners of that time were not so dramatic. A B 727 ADV with JT8D-17 engines would burn over 5300 km around 26 to of fuel in no wind conditions cruising at M 0,8.
The power of the Tu-154M shines more in its capacity to climb to FL 370 at full weight and reach its maximum operating altitude after two hours of flight. A B 727-200 ADV had to do more carful step-climbing to reach FL 390.
Thanks for the write up there walter. Ive always found the TU-154, especially the M to be quite an awesome performer. A truly great piece of machinery and underestimated by a lot of people, especially most westerners
In Tu-154Ms later service life Tupolev invented a kind of winglet to increase the effiency of the wing. In my real Tu-154M handbook there is no mention to that. With Project Tupolev Tu-154M version 2.03 the wingtips are presented with a new model-version and a special air-file called "154m_v3_06w.air" and finally "154m_v4_04w.air". This last published airfile included also high and low temprature special reactions of the engines. In practice I did not notice big differnces between the extended wing version and the normal one.
