Abstract

Abstract: This paper is intended to develop a set of the test technology of unsteady aerodynamic characteristics for the model oscillating in large amplitude pitch roll motion. The equipment was used in a 3 meter low speed wind tunnel at NUAA and a delta wing was tested. The results show that unsteady aerodynamic characteristics of a delta wing oscillating in large amplitude pitching roll motion are more complicated than in pitching motion or in roll motion.

Key words: pitching, rolling, large amplitude, unsteady wind tunnel test
