Abstract

Recently there has been considerable interest in the development of aircraft which have reduced vertical tail size compared with conventional aircraft. The tail of an aircraft produces a large radar signature and the requirement for stealth in new military aircraft necessitates the design of “tailless” aircraft. Reduction in vertical tail size results in lateral-directional response characteristics which are a great deal different from those of conventional aircraft. The objective of this paper is to examine in detail the effects of reduction of tail size on lateral-directional dynamics on a fighter type aircraft. It is shown that without stability augmentation, reduced tail size results in unacceptable handling qualities. Structured singular value or μ-synthesis is used to design controllers at two representative flight conditions. These controllers are shown to provide acceptable handling qualities and robustness to a variety of modeling errors.
