In recent years, the problem of ice formation on aircraft has received considerable attention because of its influence on military aircraft capabilities. Military aircraft and helicopters may be required to operate under icing conditions which would effect their performance, maneuverability and impair the mechanical integrity of unprotected engines. Ice formation poses a hazard to flight in that it alters the aerodynamic characteristics of lifting surfaces, reducing the maximum lift and sharply increasing the drag. In addition the ice formation may lead to control problems and, if it sloughs off, damage structures downstream. The above situations can cause serious problems for military aircraft or missiles flying over the North Atlantic and North Sea. In Europe in winter it is possible to have the proper weather conditions for ice formation up to 30 percent of the time. The ice accretion process is of prime interest in aircraft design. In order to develop and then certify certain protection systems 11-16, it is necessary to be able to test engine intakes, aerofoils in simulated icing conditions.
