Record number: 5, Textual support number: 1 CONT

A tiltwing aircraft is similar in concept to a tiltrotor design. Whereas a tilt rotor rotates the propeller from axial to dorsal, a tiltwing rotates the entire wing, not just the nacelles or prop and shaft. They are typically fully capable of VTOL operations. An advantage of tilt wing over tilt rotor is that when the rotors tilt up, the wings rotate so that they do not block the downward air.  3, record 5, English, - tilt%2Dwing%20aircraft

Bien que les Américains aient commencé à mettre en service l'appareil à rotors basculants V-22, l'avion à ailes basculantes CL-899 de Canadair avait déjà offert des capacités semblables en 1965. Ces modèles révolutionnaires, qui allient la vitesse, le rayon d'action et la capacité de transport propres aux avions à voilure fixe, ont aussi la capacité de passer en mode vertical et de faire du vol stationnaire, en changeant l'orientation des rotors ou des hélices. Mais ces genres d'appareils ont une mécanique complexe, et les programmes de vols d'essai des CL-89 et V-22 ont dans les deux cas été assombris par plusieurs écrasements. L'avion à voilure basculante CL-89 avait un avantage marqué sur les aéronefs à rotors basculants comme le modèle V-22 du fait qu'il pouvait décoller et atterrir comme un avion ordinaire, alors que les rotors surdimensionnés d'un appareil V-22 lui permettent uniquement de décoller et d'atterrir verticalement.  3, record 5, French, - avion%20%C3%A0%20ailes%20basculantes

In a skidding turn, the gyro precesses towards the inside of the turn. After return on the aircraft to straight and level flight, the instrument shows a turn in the direction of the skid. In a normal turn, the gyro precesses towards the inside of the turn. The precession error is quickly corrected by the erecting mechanism.  2, record 8, English, - erecting%20mechanism

Record number: 8, Textual support number: 2 CONT

The only really tricky part of the attitude indicator is its erecting mechanism. When power(vacuum) is first applied to the instrument, the mechanism quickly erects the gyro spindle to plumb-vertical in order to align the artificial horizon with the natural horizon. In flight, the erecting mechanism continually compensates the gyro for precession errors in order to keep it aligned throughout the course of a long flight. The design of the erecting mechanism is quite clever. In an air-driven attitude gyro, there are "pendulous vanes" suspended from pivots attached to the lower portion of the sealed gyro housing, one vane for each exhaust port. The vanes are positioned so that, when the gyro is erect, each vane half-covers its associated exhaust port. If the gyro tilts so that its axle is not plumb, the pendulous vanes shift so that one exhaust port is more-than-half-covered and the opposite exhaust port is less-than-half-covered. The resulting imbalance of discharge air exerts a force on the rotor housing at right angles to the direction of tilt, causing the gyro to precess to the erect position. As soon as the gyro is erect, the pendulous vanes return to a balanced condition to remove the precessing force. Pure magic! The erecting mechanism can erect the gyro quite quickly at initial power-up because the gyro doesn’t exhibit much gyroscopic rigidity at low rotor RPMs. Typically, the horizon bar becomes level within the first 10 or 15 seconds, and then its oscillations(caused by precessional nutation of the gyro) are damped out within a minute or so as the rotor comes up-to-speed.  3, record 8, English, - erecting%20mechanism
