Rotational accelerations stabilize leading edge vortices on revolving fly wings [PDF]
, 2009 The aerodynamic performance of hovering insects is largely explained by the presence of a stably attached leading edge vortex (LEV) on top of their wings. Although LEVs have been visualized on real, physically modeled, and simulated insects, the physical

The control of wing kinematics and flight forces in fruit flies (Drosophila spp.) [PDF]
, 1998 By simultaneously measuring flight forces and stroke kinematics in several species of fruit flies in the genus Drosophila, we have investigated the relationship between wing motion and aerodynamic force production. We induced tethered flies to vary their

, 2022 This paper presents an experimental investigation focused on aerodynamic forces and shock waves of a waverider. The study is carried out in the wind tunnel MARHy located at the ICARE laboratory of CNRS-Orleans. The facility can recreate the atmospheric re-entry flight of any vehicle in terms of viscous parameter and Knudsen number. The present work was

Integrated system to perform surrogate based aerodynamic optimisation for high-lift airfoil [PDF]
, 2016 This work deals with the aerodynamics optimisation of a generic two-dimensional three element high-lift configuration. Although the high-lift system is applied only during take-off and landing in the low speed phase of the flight the cost efficiency of ...

Application of nonlinear feedback control theory to supermaneuverable aircraft [PDF]
Controlled flight at extremely high angles of attack, far exceeding the stall angle, and/or at high angular rates is sometimes referred to as supermaneuvering flight. The objective was to examine methods for design of control laws for aircraft performing

, 2022 Hypersonic vehicles are more and more studied in the military domain but also for other missions as the interplanetary or commercial missions. These vehicles optimize the ratio between lift and drag forces to success their missions. Hypersonic vehicles studied are launched at high altitude by rockets and they realize a re-entry by changing their angle ...
