The toroidal propeller allows a small multirotor unpiloted aircraft, or drone, to operate more quietly than current drones that use propeller forms unchanged since the beginning of aviation. [It] consists of two blades looping together so that the tip of one blade curves back into the other. This closed-form structure minimizes the drag effects of swirling air tunnels... created at the tips of blades and strengthens the overall stiffness of the propeller. These features reduce the propeller's acoustic signature. 2, record 1, English, - toroidal%20propeller

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 3, English, - active%20radiator%20grille%20shutters

Cuanto más rápido se mueva el objeto, más rozamiento se producirá, hasta llegar al punto en que la fuerza de rozamiento contra el aire sea igual a la fuerza con la que el objeto cae. Es entonces cuando el sistema objeto-gravedad-aire llega al equilibrio: pese a que la gravedad terrestre intenta acelerar aún más el objeto, el rozamiento contra el aire es tan grande que no lo permite.

The term feathering refers to the operation of rotating the blades of a propeller to an edge-to-the-wind position for the purpose of stopping the rotation of the propeller whose blades are thus feathered and to reduce drag. Therefore, a feathered blade is an approximate in-line-of-flight position, streamlined with the line of flight. Some, but not all, propellers can be feathered. Feathering is necessary when an engine fails or when it is desirable to shut off an engine in flight. The pressure of the air on the face and back of the feathered blade is equal, and the propeller will stop rotating. If it is not feathered when its engine stops driving it, the propeller will "windmill" and cause drag. 3, record 6, English, - feathering

Orbit control [consists in] controlling satellites to keep [them] flying on the designated orbit. When a satellite flies in low earth orbit(LEO), it gradually descends due to air drag. It is necessary to push the satellite back to the original orbit by activating station-keeping thrusters. Geostationary satellites do not descend due to air drag, however, they do de-orbit from their designated stationary position because the gravitational field of the Earth is not uniform and because the gravitational pull of the Sun and the Moon alters their orbit. In a similar way, geostationary satellites are pushed back to their original position by activating station-keeping thrusters. 2, record 17, English, - orbit%20control

Generally, the greater the wind speed then the greater the surface ocean current speed. The wind force acting on the surface of ocean is called wind stress and denoted by Tau. Wind stress acts in the direction of the wind on the surface. In contrast, pressure acts perpendicular to the surface. ... Wind stress [(tau)] is a force per unit area. [tau] = mass[star]acceleration/area. Units should be kg[star]/s²·/m² (Newton = kg[star]m/s²). So [tau] is in Newton/m².

Another increasingly popular type of anemometer is the propeller anemometer. This anemometer is simply a very small two-or three-blade propeller, calibrated so that the revolutions per minute(rpm) corresponds to specific wind speeds. This anemometer is known as a "lift" device because it relies upon the rational lift caused by the wind on the propellers to measure the wind speed. By using two propellers held fixed at a perpendicular angle to each other, one can simultaneously measure the wind speed and direction using vector analysis. By including a third propeller positioned vertically relative to the other two, vertical wind movements also can be measured. It should be noted that the effect of variations in air density(due to temperature and/or pressure conditions) are accounted for differently in lift devices(for example, propeller anemometers) and drag devices(for example, cup anemometers). 4, record 20, English, - propeller%20anemometer

STEP : Satellite Test of the Equivalence Principle. Worden and Everitt have proposed to carry out an improved version of Galileo's Leaning Tower of Pisa experiment, by placing masses of different composition inside a satellite orbiting the Earth to obtain a long duration of free fall. Very high positional sensitivity can be achieved by cooling the experiment to 1. 8 K and using SQUIDs to detect in current changes in magnetic pickup coils. The test masses of different materials and the position measuring equipment are placed inside the satellite and micro Newton thrusters are used to cancel the small accelerations of the satellite due to air drag, radiation pressure and the solar wind which could couple to masses. 2, record 22, English, - satellite%20test%20of%20the%20equivalence%20principle

Plotted over a sufficiently large number of points around an aerodynamic shape, these equations can predict lift, drag and heating.

Mine roadways offer resistance to air flow due mainly by surface drag between air and roadway sides(...) Energy losses are directly proportional to the cube of the air quantity flowing. A simpler pressure difference relationship is used which is derived from basic fluid flow principles and which can be related to Atkinson's equation. In this case P=RQ [squared] where P is the frictional pressure difference across a length of roadway in pascals : R is the roadway resistance in Gauls(...) ;and Q the air-flow rate in [cub metre]/s.
