Inverse design of aerodynamic configuration using generative topographic mapping
Xibei Gongye Daxue Xuebao, 2022 The inverse design method of aerodynamic configuration is hard to give a reasonable pressure distribution, and strongly rely on experience of designers. The method has been difficult to adapt to the needs of modern aircraft design.

Aerodynamics of Flying Saucers [PDF]
Communications in Mathematical Physics, 2020 We identify various structures on the configuration space C of a flying saucer, moving in a three-dimensional smooth manifold M. Always C is a five-dimensional contact manifold. If M has a projective structure, then C is its twistor space and is equipped with an almost contact Legendrean structure.

Evaluation of Aerodynamic Characteristics in Oscillatory Coning Using CFD Methods [PDF]
Proceedings of the 9th European Conference for Aerospace Sciences,
2022, 2022 The wind tunnel rotary-balance testing is widely used in aircraft dynamics to characterise aerodynamics at moderate and high angles of attack during stall and spin regimes. In such experiments an aircraft test model is rotated along the wind-tunnel free-stream velocity vector allowing the measurement of aerodynamic characteristics in steady rotational ...
