  • Method of, and apparatus for, de-icing an aircraft by infrared radiation
    Patent number: 5417389
    Abstract: An improved apparatus (11) for emitting infrared radiation of a desired wavelength includes a primary surface (35); a burner (24) for raising the temperature of the primary surface so as to cause the primary surface to emit infrared radiation of a first wavelength; a secondary surface (26) surrounding the primary surface in spaced relation thereto and arranged to be heated by infrared radiation emitted by the first surface and for emitting infrared radiation of a second wavelength toward the object; and an actuator (28) for selectively varying the spacing between the primary and secondary surfaces so that infrared radiation emitted by the secondary surface will be at a desired wavelength and will be focused; whereby the apparatus will emit infrared radiation of a desired wavelength toward the object.
    Type: Grant
    Filed: March 7, 1994
    Date of Patent: May 23, 1995
    Assignee: Radiant Energy Corporation
