Abstract

SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.

Abstract

Fiber optic sensors, Fiber Bragg Grating (FBG) sensors in particular, are among most promising sensors for structural health monitoring of aerospace structures in order to assess the safety and durability during a long period of time in use. These sensors are expected to provide a low-cost maintenance methodology for carbon fiber reinforced composite structures which are now extensively being used for the primary structures. This chapter presents an overview of current use of FBG sensors in aeronautics and astronautics.
