There is a new paradigm emerging in which the technology for new airplane programs is developed in many different countries. The subject of this paper will be to investigate the different models of international cooperation, giving examples of several programs Boeing now has in work. In the past, the technology required for a new Boeing commercial airplane program was largely developed in the USA by Boeing and it's key suppliers. Over the last ten years, this has begun to change, as Boeing seeks to utilize the talents and capabilities of technology developers around the world. A listing of the suppliers providing components for the 777 shows participation from around the globe. (Figure 1). In the course of developing the 777, the expertise of Japan Aircraft Industries, Alenia of Italy, Hawker deHaviliand and ASTA of Australia, and others was utilized to create the premier commercial transport in service today. As Boeing takes the next step beyond the 777, the challenge is to use these worldwide to create the underlying technology for the next generation of airplanes. There are several models of cooperation, which can be applied to this task. The first we will is Research and Development work under contract. Two examples of this type of arrangement will be examined.

At that paper the possibility and efficiency of Long Range Ultra High Capacity Passenger aircraft design using the multiplane wing lifting system is investigated on the basis of Jukovsky Military Air Academy and Moscow State Aviation Institute work. The main peculiarity of "polyplane" layout configurations is the fact that aerodynamic planes are joined in tethraedal consoles and have high strengthens and stiffness in all direction of loads which results in practical independence of the relative structure weight from the aircraft's take off weight. And besides such layout configuration allows to decrease the induced drag of aircraft. The conclusion can be made that the advantages of the "polyplane" configuration can be realized at high values of aircraft's take off weight - 400...500 tonns.

At that paper a new aerodynamic scheme "Polyplane" is suggested fog ultra high capacity aircarft and peculiarities of it's load carrying structure are investigated. The calculation schemes and results of finite element calculations are presented. The comparison with the conventional aerodynamic scheme was made and conclusions about the weight efficiency of such a scheme are listed below.
