Experience from environmental trials on helicopters is reviewed to show how life of main and tail rotor blades was reduced by erosion and how effective various modifications have been in protecting blades; compressors of gas turbine power units were also affected by sand ingestion and intake filters were used on later trials to protect engines; engine erosion problem is discussed with reference to position of intake, degree and type of filtration and design of compressor itself; design features of helicopter which affect its ability to operate in dust and salt-laden atmosphere are considered and suggestions made.
