Approach based on specialized program algorithms and test methods was developed for searching pro-composite concepts and layouts for civil aircraft. Significant weight benefit was obtained for some airframes. The main reason of high weight effectiveness of these airframes is new concept of using skin in composite wing and fuselage structures.
