Fluid De-icing Tests on a Chandler-Evans 1900 CPB-3 Carburetor Mounted on a Pratt & Whitney R-1830-04 Intermediate Rear Engine Section

摘要

Tests were conducted to determine most effective method of injecting de-icing fluids to remove heavy ice formation from the induction system and carburetor of aircraft engines. Experiments were made at 25 and 40 deg F to evaluate effect of inlet-air temperature on de-icing fluid effectiveness. Results show that use of de-icing fluids is inadequate as the sole means of de- icing induction system when it is subjected to severe icing conditions.
