  • Electric heater for integration into an aircraft acoustic panel
    Patent number: 8919494
    Abstract: An electric heater (40) for integration into an acoustic panel (20) having sound-penetrating pores (30) communicating with a sound-canceling medium. The heater (40) includes an electrically conductive layer (53) with resistance-setting apertures (63) filled with sealant (73). Openings (83), which contribute to the sound-penetrating pores (30), extend through the sealant-filled apertures (63). The acoustic panel (20) can be assimilated into an aircraft component, such as a nacelle inlet lip, which requires both noise-reducing and ice-protecting features.

  • Airfoil low ice adhesion surface
    Patent number: 6247669
    Abstract: A pneumatic deicing system includes a deicer assembly comprised of an outer layer having a low modulus of elasticity, an inner ply, and a plurality of inflatable members provided therebetween for imposing strain in ice accumulated thereon. The deicer assembly is disposed directly on top of and bonded to the leading edge of an airfoil. The deicer has a plurality of large radius spanwise running inflatable members arranged substantially parallel to the leading edge and a plurality of small radius spanwise running inflatable members arranged substantially parallel to the leading edge and disposed chordwise aft of the large radius spanwise running inflatable members. The small radius inflatable members are covered with a low ice adhesion surface.

  • Impedance type ice detector
    Patent number: 5955887
    Abstract: An ice detector includes a pair of electrodes connected by a pair of leads to a control unit which measures the total impedance between leads to thereby sense and detect the presence of ice and other contaminants formed on top thereof utilizing a comparator circuit. The electrodes are integrated into patch which can be placed at different locations on an aircraft.
