Abstract
To prevent deposition of ice on the frontal surface of for instance, the horizontal tail of aircraft anti-icing member is installed in front of the edge along its entire length. The member has an airfoil profile with a chord equal to 3-8% of that of the tail to be protected and is located in a zone not exceeding the tail is thickness, a duct being formed between the member and the surface to be protected for the passage of an accelerated air stream.
Claims6
An improved anti-icing apparatus for preventing ice formation on the aerodynamic surface of an aircraft, in particular a horizontal tail, said apparatus having an elongated anti-icing member installed in front of the tail being protected, in a zone not exceeding the thickness of the tail at a distance from a conventional frontal surface of the tail, along the whole length thereof, and along the frontal surface, the tail retaining its conventional airfoil profile in its frontal portion, said improvement comprising:
- defining said anti-icing member by an airfoil profile in its cross section, the distance between the tip of the anti-icing member and the frontal surface of the tail being equal to 1-3% of the chord of the tail, the frontal surface and a back surface of said anti-icing member defining a duct for the passage of an accelerated air stream around the frontal surface of the tail being protected, said anti-icing member having a profile with a chord equal to 3-8% of the chord of the tail being protected, said anti-icing member being located in front of the tail at an angle of 30.degree.-60.degree. to the tail chord plane.
