During the last 20 years air traffic has more than doubled. This trend of perpetual growth will continue and the environmental impact of air traffic will gain increasing importance. Governmental authorities and international political initiatives will further tighten noise and emission regulations for air traffic vehicles. Regulations will not only be related to local impact around airport areas as done so far, the global impact of exhaust emissions will be traced across the atmosphere as well.

This trend will result in higher noise and emission fees for the airlines and customer or even cause flight restrictions. In the end, it may prohibit the growth of the aero industry as a whole.

The environmental issues will be in addition to the general demand for more fuel-efficient and more affordable and engines. Economics will continue to dominate future aero engine design. Environmental technologies therefore will have to follow a strong challenge from aggressive cost targets as dictated by the market.

To solve all this problems aero engine manufacturers have to work on new technologies, engine concepts and manufacturing procedures.

Present paper will give an overview on the future aero engine design. It will illustrate the future engine requirements and the effort from aero engine industry to find answers to these needs in conjunction with the increasing economic market constraints. Special emphasis will be concentrated on the efforts taken by MTU and it's research partners.
