Tupolev Tu-444
The Tupolev Tu -444 is the name of a design for a supersonic business jet of the Russian manufacturer Tupolev PSC.
History
Tupolev has extensive experience in designing and manufacturing of supersonic aircraft, both in the military field, such as the Tupolev Tu -22 M3 and Tupolev Tu-160, as well as in the civilian sector with the Tupolev Tu- 144 and its derivative Tu- 144LL.
However prohibit the current regulations relating to the environment and in particular noise, it de facto, to start an economically implementable project of a large supersonic transport aircraft. Realistically, the construction of a smaller business jet appears. This project was designated Tu- 444. Above all, it is much cheaper to implement such an aircraft, as would be the case on a commercial aircraft, and compliance with environmental regulations is much easier to deal with. However, this requires new developments. Also, if appropriate, take off and landing must be automated in order to meet the requirements.
Analyzes of known economic institutes have shown that the market for such aircraft is about 400 to 700 pieces. This condition is only that the supersonic models should not be more than 20% more expensive than conventional aircraft. The main argument is that intercontinental missions can be completed in one day and still have an entire working day is available on site.
An important point is the consistent profitability in both the sub - as in the supersonic range. Also, the coverage benefits do not differ in the two operating states.
Construction
The design is a twin-engine low-wing monoplane with a double -delta wing, single vertical tail and a Kippnase. The two engines are located below the wing. In addition, an auxiliary power unit (APU) located in the rear. The aircraft will be built largely from composite materials.
