Lift Enhancement of Tiltrotor Wing Using a Gurney Flap
International Journal of Aerospace Engineering, 2022 A numerical investigation was undertaken to explore the lift-enhancing characteristics of the Gurney flap on a tiltrotor wing. The heights of Gurney flaps range from 1 to 4% wing chord lengths.

The Role of Hematopoietic Cell Transplantation in Ataxia‐Telangiectasia
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Ataxia‐telangiectasia (A‐T) is a DNA repair disorder characterized by neurodegeneration, immunodeficiency, and cancer predisposition. Hematopoietic cell transplantation (HCT) is an established therapy in related disorders such as Fanconi anemia (FA) and Nijmegen breakage syndrome (NBS), but its role in A‐T is unclear.

Gurney flap effect using jet induced by plasma actuator
Nihon Kikai Gakkai ronbunshu, 2015 Lift and drag variations by plasma actuators have been investigated under flow at low Reynolds numbers ranging from 1.7×104 to 6.6×104. Wall-normal-jet type and counter-jet type plasma actuators are attached on the pressure surface near the trailing edge
