Ice formation on aircraft has long been a hazard to commercial and The military aviation, as well as the private flyer. Besides affecting the safety and performance of aircraft, severe icing conditions have been the cause of a large number of flight interruptions. Ice formation on the wings, tail surfaces, and fuselage is responsible for an increase in weight and the loss of aerodynamic efficiency. Severe vibrations and loss in thrust may result from ice accumulation. During heavy ice conditions in which ice occurs on the propellers and the aircraft simultaneously, the plane may be unable to climb properly, or maintain altitude, causing an emergency landing. The issue of determining adequate and practical means of combating ice formation has brought deicing and anti-icing systems to the forefront in aircraft design. This blog will focus on bleed air technology, pitot tube heating, propeller ice prevention, and heated edges systems.
