The continuous evolution in the design of aircraft engines increasingly aimed at optimizing the power / weight ratio required to support the design of pure computational tools that make it both more immediate results, trying to optimize the computation time, both the interpretation of the results with a set of objective data obtained on the dyno. E 'be a need for appropriate tools that become part of the design stessa.Per ensure containment of the weights, necessary objective in aviation, it is essential to focus on the manufacturing techniques and materials to be used. It is therefore of high priority to optimize the processes that underlie the production of aircraft components.

The success in automotive diesel engines of latest generation common rail direct injection, suggested the idea of ​​using this type of engines in the aeronautical field, thanks to the following advantages: first, these engines have a specific weight, frontal area and power consumption lower than gasoline engines. They are also characterized by low CO2 and NOx, the diesel does not contain lead or other toxic substances and there are problems of fuel availability. The high efficiency at part load combined with a fuel cost significantly less than that of the gasoline allow a considerable economy of operation. However, the use at high altitude in low pressure of the combustion air inlet is a condition of abnormal operation compared to the use automotive and requires careful consideration. This application presents a number of issues to be resolved, which focuses on the research in question. First, the automobile engine requires structural adjustments and the level of external components to be subjected to severe tests, for which you must create an ad hoc test structures. Furthermore, the operation at high altitude has some issues that need to be simulated using a sophisticated exhaust system / power. By implementing a sophisticated data acquisition system will be possible to measure the quantities of interest in the game and then optimize the response of centralina.Nell 'scope of work for materials used in aircraft, it is a strong need to optimize the 'use of machines and systems for industrial processes using the most advanced technologies, mechanical, electronic, software and services. This also in view of the growing attention from major markets around the world who appreciate its advanced technology, reliability, security, processing precision, efficiency, care and attention to construction details aesthetics.
