        abstract = {Gust loads represent a critical design constraint for civil transport aircraft, directly influencing structural weight, fatigue life, and passenger comfort. Conventional gust load alleviation strategies rely on moving-surface control devices such as flaps and ailerons; however, their large inertia limits effective response to low-frequency disturbances, leaving higher-frequency gust loads to be absorbed structurally. Recent advances in active flow control have introduced mechanical and fluidic microactuators as promising alternatives for high-frequency load mitigation. In this study, the effectiveness of fluidic microjets for aerodynamic load control is investigated numerically at subsonic and transonic conditions. Simulations are performed on the RAE 2822 airfoil equipped with a trailing-edge microjet using the Reynolds-averaged Navier–Stokes equations solved with the CFL3D solver. Both conventional normal jets and upstream-directed microjets are examined at a fixed momentum coefficient. The results demonstrate that fluidic actuation provides a nearly linear lift reduction with respect to the square root of the momentum coefficient. While both jet configurations effectively reduce lift, upstream-directed jets achieve superior load alleviation by enlarging the separation region and increasing suction-side pressure. Furthermore, at transonic speeds, upstream jets mitigate shock-induced drag penalties, resulting in lower overall power consumption compared to normal jets. These findings highlight the potential of upstream fluidic microjets as an efficient and reliable solution for gust load alleviation in future transport aircraft.},
