Abstract

A flying wing cancels horizontal and vertical tails, but the changes of configuration and the use of drag rudder make it differ much from the conventional configuration aircraft in three-axis stability characteristics. The aircraft chosen for the study is a flying wing with high aspect ratio. Its three-axis static and dynamic stability characteristics are studied. Comparing with the conventional configuration aircraft with high aspect ratio, the effects of configuration parameters and typical flight condition on the stabilities of the flying wing are discussed. The impact of the drag rudder on the stabilities of such aircraft types is also analyzed. Results show that there are many deficiencies in the inherent three-axis stabilities of the high aspect ratio flying wing.

Key words
