Prevention of Ice on Windscreens

Prevention of Ice on Windscreens THE National Advisory Committee for Aeronautics is conducting a programme of research intended to reduce the risks now attendant on aeroplane operation during icing conditions. A part of this programme is concerned with the prevention of ice on the windshield. The methods investigated involve the use of 1 heat from an electric source, 2 heat from the engine exhaust, and 3 an alcoholdispensing, rotating wiperblade. Inasmuch as the problem of ice prevention exists in several forms, it is anticipated that several different methods may find application on the aeroplane. The obstructions of vision through a windshield may result from ice or snow formations on the exterior surface or from the formation of frost on the interior. The object of the present investigation, therefore, was to determine the extent to which the several methods could preserve vision. Observations were also made to determine the capacity of the rotating wiperblade to remove rain from the windshield. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Aircraft Engineering and Aerospace Technology Emerald Publishing

Abstract

THE National Advisory Committee for Aeronautics is conducting a programme of research intended to reduce the risks now attendant on aeroplane operation during icing conditions. A part of this programme is concerned with the prevention of ice on the windshield. The methods investigated involve the use of 1 heat from an electric source, 2 heat from the engine exhaust, and 3 an alcoholdispensing, rotating wiperblade. Inasmuch as the problem of ice prevention exists in several forms, it is anticipated that several different methods may find application on the aeroplane. The obstructions of vision through a windshield may result from ice or snow formations on the exterior surface or from the formation of frost on the interior. The object of the present investigation, therefore, was to determine the extent to which the several methods could preserve vision. Observations were also made to determine the capacity of the rotating wiperblade to remove rain from the windshield.
