Abstract
An analysis of the critical factors affecting the next generation supersonic transport flight safety, due to the features of the low sonic boom configuration, was carried out. A new concept of a hybrid airframe design of a supersonic passenger jet based on pro-bionic sections and sections of conventional structural layout was proposed. Pro-bionic sections were developed on the basis of composite lattice structures. Previously, this type of structural layouts has been successfully adapted in commercial space vehicles in Russia and the EU. Pro-bionic supersonic passenger jet airframe sections include a rigid composite frame of unidirectional ribs, elastic panels based on 3D reinforced woven skins. These sections are equipped with a built-in structural health monitoring system based on fiber optic sensors. New principles for ensuring pro-bionic structural strength and enhanced flight safety based on the positive synergetic interaction of the primary structural elements are proposed and validated. The weight efficiency of pro-bionic structures is estimated.
