EIDI - Electro Impulse Deicing
Electro Impulse Deicing is an acceleration based deicer for use on large
aircraft, ship and bridge surfaces for general ice protection. The system was developed
in collaboration with a NASA Glenn SBIR program. An electromagnetic coil is
placed behind the surface skin that induces strong eddy currents in the metal
surface. As a result, strong opposing forces are developed between the actuator
coil and the metal skin. This results in a rapid acceleration that sheds and
de-bonds ice into the air stream in a very efficient manner (ice layers can be
shed as thin as .050").
EIDI represents a technically advanced low power deicing system alternative
to electrothemal and bleed air anti-icing systems. IDI's
Icing Onset Sensorcan be added to the basic system
to provide an autonomous mode of operation. The IOS detects the initiation
of ice accretion (icing onset) and continuously monitors the amount of
accumulation. When the accumulation reaches a thickness threshold at which
efficient clearing is possible, the sensor commands the deicer to fire. Because
the sensor continuously monitors the accumulation, the sensor can determine if
the ice was properly shed or if another clearing cycle is required. The sensor
continues to monitor accretion and initiate deicing cycles as required.
IDI is known for development of advance deicing technology as we were part
of the development team for a new Expulsive de-icing system recently certified
for the Raytheon Premier I business jet. This system was the first all new
de-icing technology FAA certified in over 30 years.
IDI provides engineering services to adapt or custom design new de-icing
systems to meet specific customer needs for aircraft, ships, bridges, buildings
and antenna structures.
