Turbine Engine Icing and Ice Detection [PDF]
ASME 1972 International Gas Turbine and Fluids Engineering Conference and Products Show, 1972 A review of conditions necessary for turbine engine icing is presented along with the potential problems caused by engine icing. Methods of protecting the engine against icing are briefly presented and a method of automatic anti-ice operation is proposed.

The Effects of Wind Induced Conductor Motion on Accreted Atmospheric Ice [PDF]
, 2013 Galloping of transmission lines creates some cyclic stresses in the conductor and accreted atmospheric ice covering the conductor, which may result in ice failure leading to shedding.

Detecting Clouds Associated with Jet Engine Ice Crystal Icing [PDF]
Bulletin of the American Meteorological Society, 2019 AbstractIn the past two decades, more than 150 jet engine power-loss and damage events have been attributed to a phenomenon known as ice crystal icing (ICI). Ingestion of large numbers of ice particles into the engine core are thought to be responsible for these events, which typically occur at high altitudes near large convective systems in tropical ...

Vibration of Bundled Conductors Following Ice Shedding [PDF]
, 2008 The dynamic behavior of bundled conductors following ice shedding from one subconductor is examined numerically using the finite-element method. An existing model of ice shedding from a single conductor is improved by developing a model of spacers which ...
