Extract

The high values of specific strength and stiffness of carbon fibre composite materials have already been discussed by Mr. T. Sharpies in his paper and require no further comment. Therefore, I would like to consider the benefits to direct operating costs (DOC) which can be obtained by the application of Carbon Fibre Composites (CFC) to a civil transport aircraft.

Figure 1 is taken from a paper presented by Stewart and Campion at the Atlantic Aeronautical Conference last year. In this figure are shown the benefits in DOC which arise due to the application of the following advanced technologies:

Advanced aerodynamic wing design

Stability augmentation and load alleviation

Advanced composite structures.
