  • Method and a system for treating ice for an aircraft windshield
    Patent number: 9868535
    Abstract: A method of treating ice for a windshield of an aircraft, in which method at least two distinct de-icing zones of the windshield are defined. During a de-icing step, at least one de-icing means is activated temporarily in order to de-ice the de-icing zones in succession and in a given cycle.
    Type: Grant

  • Method of regulating the speed at which a rotorcraft rotor is driven under icing conditions
    Patent number: 9580182
    Abstract: A method of regulating the NR speed at which the rotor of a rotorcraft is driven in rotation. On detecting that the rotorcraft is flying under icing conditions in a previously identified critical temperature domain (Dct), the NR speed is either decreased in the situation where the ambient outside air temperature (OAT) lies in a low temperature icing range (Ptb) of the critical temperature domain (Dct), or else it is increased in the situation where the ambient outside air temperature (OAT) lies within a high temperature icing range (Pth) of the critical temperature domain (Dct).

  • Blade with minimized vulnerability
    Patent number: 9011102
    Abstract: A blade (1) having a working shell (10) defining an inner space (16). The blade has a leading-edge space (31) and at least one filler means (40, 50) in said inner space (16) and a leading-edge fairing (20) protecting the working shell (10). The fairing (20) extends from a pressure-side part (21) to a suction-side part (22) via a central part (23). The working shell (10) has in the first zone (13): a pressure-side portion (131), a central portion (133), and a suction-side portion (132). The pressure-side portion (131) is secured to the pressure-side part (21). The suction-side portion (132) is secured to the suction-side part (22). The blade (10) includes first damper means (60) with damping material.
