Wind energy is the world's fastest growing renewable source of electricity … the atmospheric flows are strongly volatile, and therefore, the average wind speed at a given location is a very poor predictor of the energy output of a wind turbine. The basic requirement for wind power estimates is an adequate characterization of the empirical probability distribution of wind speeds since wind direction is less important because of the well developed methods of yaw control for modern turbines. The statistical description is highly simplified when a measured histogram can be accurately fitted by an analytical probability density function(PDF) with a few parameters. The traditional approach of modeling the wind speed PDF is based on the Rayleigh and the more flexible Weibull distributions. However, several authors noted that Weibull fits of empirical data have low quality at several locations, mostly over land.  4, record 11, English, - wind%20probability%20density%20function

Wheelbarrowing is a condition that arises when the nosewheel rather than the main gear is forced to support an abnormal share of the aircraft’s weight. Touching down on the nosewheel, excessive braking, or friction between the wheels and runway caused by a side-skid may cause wheelbarrowing.

During take-off, "wheelbarrowing" may occur at lower speeds than during landing due to the slipstream increasing the lifting effect of the horizontal stabilizer.

L'atmosphère dans laquelle se déplace un avion n'est pas immobile. Elle est le siège de divers mouvements dont certains sont de grande échelle, comme le vent, et d'autres d'échelle beaucoup plus réduite, comme les turbulences ou encore les perturbations créées par les avions eux-mêmes. En effet lorsqu'un avion se déplace il crée un sillage constitué de deux gros tourbillons contrarotatifs qui prennent naissance aux extrémités des ailes et dont l'intensité décroît lentement. Toutes ces perturbations vont affecter le vol de l'avion. Elles peuvent créer, en particulier, des déplacements verticaux et des mouvements de roulis dangereux, surtout s'ils se produisent à proximité du sol au cours des phases de décollage ou d'atterrissage.  2, record 27, French, - perturbation%20d%27attitude%20en%20roulis

The on-orbit Attitude Determination and Control Subsystem(ADACS) provides three axis pointing control for the satellite. The ADACS maintains system pointing by controlling torque in three mutually orthogonal wheels. The torque is determined by analysis of spacecraft orientation in space. Input to these computations are acquired from the Earth Sensor Assembly(ESA) for pitch and roll, and an inertial reference with sun sensor updates for yaw.  2, record 28, English, - inertial%20reference

Stabilisation and orientation by inertial flywheels consists in accurately aligning the axes of three flywheels with the axes of reference(roll, pitch and yaw). When one of these flywheels is moved in yaw by an electric motor, its angular moment increases and the vehicle is subjected to a reactive couple. Inertial flywheels provide very fine control of orientation or stabilisation, because the couples set up may be very small.  1, record 29, English, - inertial%20flywheel

Les satellites ont besoin d'être dotés d'équipements permettant : - de repérer l'attitude du satellite par rapport à des repères extérieurs (terre, soleil); - de régler cette attitude en fonction des missions; - d'ajuster les paramètres de l'orbite. Ces fonctions sont assurées par le sous-système de stabilisation (mesure et contrôle d'attitude et d'orbite). Les roues à inertie sont un des dispositifs du sous-système de stabilisation et d'orientation. Il existe deux grands types de roue à inertie : - les roues à paliers classiques (roulements à billes); - les roues à paliers magnétiques (suppression des frottements mécaniques permettant une minimisation des vibrations).

In modern gyropilots rate detection forms the principal reference and displacements detection plays a secondary role. In such designs yaw disturbance is detected by a rate gyroscope and the change in heading is detected by the associated gyrocompass.  1, record 31, English, - yaw%20disturbance

The Ausroc 3(A3) launch vehicle has a liquid fuelled motor that burns JA-1 kerosene with liquid oxygen, and uses regenerative cooling. The motor produces 35 kN at sea level and has a burn time of 80 seconds. The motor is gimballed to facilitate pitch and yaw control. The wall of the combustion chamber, throat and expansion nozzle consists of 102 stainless steel tubes stacked side by side running parallel to the motor axis. The tubes will be brazed together and the assembly wrapped in a carbon fibre composite. The composite wrapping is used to relieve to tubes of the hoop stress generated by the combustion pressure(2 MPa), whilst the tubes contain the combustion heat(3500 K). The top end of the motor has a kerosene inlet manifolt, oxygen dome and injector block. The kerosene inlet manifold delivers kerosene to every second motor tube, where it travels down to the arse end of the motor. Here it enters the lower kerosene manifold which is a simple plenum ring. This allows the kerosene to flow into the other alternate tubes which deliver it back up to the inlet manifold. The inlet manifold then directs the kerosene to the injector block, which sprays it and the liquid oxygen into the combustion chamber.  2, record 33, English, - liquid%20fuelled%20motor
