The fenestron, [like] a conventional tail rotor, [features] spinning blades that generate a thrust force to cancel out the tendency of a helicopter fuselage to rotate. However, the fenestron rotor differs from a conventional rotor by adding several more blades.... Compared to conventional tail rotor blades, the fenestron blades are also much smaller and spin at higher speeds. Furthermore, these blades are mounted within a shroud that forms part of the vertical tail fin of the helicopter. This configuration turns the rotor into a ducted fan whose blade tips are protected from the external air.  3, record 2, English, - fantail

Un fenestron est une cavité carénée hébergeant le rotor anticouple de queue d'un hélicoptère. Les rotors de queue conventionnels ont de 2 à 4 pales. Les rotors de queue dans des fenestrons ont de 8 à 18 pales de taille plus réduite. Elles ont des angles d'incidence différents qui font que le bruit est réparti sur différentes fréquences et de ce fait est moins intense. Le fenestron permet une vitesse de rotation supérieure.  2, record 2, French, - fenestron

Comme sur tous les hélicoptères qui en sont équipés, le fenestron est avant tout un équipement qui participe à l'amélioration de la sécurité de l’appareil et de ses opérateurs. En carénant le rotor anticouple, on le protège des risques de collision au sol tout en évitant les accidents qui peuvent concerner les personnels au sol. [...] Même en cas de destruction ou de panne du rotor anticouple lui-même pendant le vol, les propriétés aérodynamiques du carénage du fenestron apporteraient une sécurité additionnelle.  3, record 2, French, - fenestron

StratSat provides a geo-stationary platform at 20 km altitude capable of remaining on-station for up to five years. Payloads include high speed Internet services, direct broadcast TV, mobile telecommunication, etc. The envelope operates as a super-pressure hull(i. e. with no ballonet pressure control system). The hull will be of laminated fabric construction with Tedlar/Teflon, helium/weather barrier developed from AT-10/04. Multiple catenary curtain system supporting a payload module enclosed completely by the envelope. [The] payload module... comprises a single structural module with an externally mounted payload/mission system. The payload module provides a home for all of the airship's primary systems except for the propulsion system. The systems are close packed within the highly insulated module ensuring efficient heat and energy management. The payload module is pendulum stabilised within the envelope. The solar array provides the sole source of renewable energy for the airship. The array is placed over the upper quarter of the hull and extends over approximately three-quarters of the length of the craft. The array can be realigned to the daily sun location/angle by the roll rotation of the whole airship. The energy collected by the solar array is stored for use during the night in the series of batteries. Located in the stored for use during the night in a series of batteries. Located in the payload module, the batteries run the propulsion system, airship services and provide power to the mission system for up to 14 hours(during winter). The airship is propelled and steered by means of a ’Contra-Rotating Coned Rotor’ mounted on a tailcone at the rear of the envelope, as a part of a compound propulsion system. The unit provides longitudinal thrust(to counter the prevailing stratospheric winds) and lateral force(for manoeuvering) to enable the airship to hold station within a 1 km cube. The airship will be equipped with a multi-channel Flight Control Sy  7, record 5, English, - StratSat%C2%AE

The tail rotor assembly is made up of a mast, hub, two scissors assemblies, four pitch control rods, slider, spider, four dampers, four blades and control(extension) rod.... The variation of the collective pitch of the blades for the thrust control is possible due to a translational movement(inwards and outwards) of the four pitch control rods. The spider-slider assembly rotates together with the hub-blades system and translates together with the extension rod, which is moved by a servoactuator system. The two scissors assemblies keep the spider-slider assembly rotating together with the hub. The dampers have the function of damping the lag movement.  2, record 8, English, - spider
