The difference of the aerodynamic influence of two engine models... on [the] airframe is analyzed... The results indicate that at cruise condition, the engine shape is a primary factor affecting the... airframe upper fuselage surface flow, the two engine models exhibit a similar aerodynamic influence on the... airframe. However, at takeoff condition, the two engine models’ aerodynamic influence on the airframe is different, because of the air suction caused by the WPN [with powered nacelle] engine model affecting the airframe upper fuselage surface flow... 1, record 1, English, - aerodynamic%20influence

Active grille shutters, which improve efficiency by opening and closing automatically to control airflow, are popping up on a number of new [car] models... When they’re open, the shutters allow air to flow through the radiator and into the engine compartment, as usual, to promote cooling. But when that cooling air is not needed, the shutters close, rerouting air around the vehicle to lessen aerodynamic drag and reduce fuel consumption. As an added bonus, closed shutters also reduce warm-up time in cold weather. 7, record 2, English, - active%20radiator%20grille%20shutters
