STC Received For The ThermaWing™ Ice Protection System On The Columbia 350 & 400
March 2006 - Kelly Aerospace Thermal Systems officially announced that it has received supplemental
type certification (STC SA02260CH) on the Columbia 350 & 400 for its Thermawing™ ice protection
system. Thermawing™ is the most advanced aircraft deicing system available on the market.
Features:
- Typical weight including the alternator is 36 lbs.
- Heating element is made of a flexible graphite foil that allows for instant heat rise.
- It has a protective Tedlar (registered) covering
- Heaters can bond to most aircraft surfaces with minimal alteration.
- Digital system controller that automatically operates the deicing system. When a pilot activates the system it will wait for the temperature to drop below 41 deg. F. and then initiate a cycle.
The Thermawing's™ reliable operation is rooted in its fundamental features and quality design. The current control methodology provides for the least amount of runback and creates the best scenario for low power ice protection systems.
At power up of the avionics bus, the deice system initializes itself and then waits for operator action. During engine run-up, the pilot will enable the deice system with the engine at run-up RPM. While the pilot proceeds with other tasks in the run up check, the deice system will go through a complete system check and then be ready for normal operation. At any time later, enabling the deice system starts with an immediate shed cycle if below 41F/5C and more than 30 seconds has elapsed since the most recent shed cycle, and then continues as below (the pilot can force a shed cycle at intervals of 30 seconds or greater below 41F by simply disabling and re-enabling the system).
Deicing is enabled any time OAT is below 41F/5C and the deice switch is selected on. Each heater is partitioned into a "shed zone" and a "parting strip". The parting strip covers a narrow span wise region along the airflow separation point on the leading edge, and maintains an ice-free line along the leading edge. The shed zone covers an area several inches back from the leading edge on both surfaces of the airfoil, and is used to break the bond between ice and the airfoil surface so that aerodynamic forces can remove accumulated ice. The two zones are powered in parallel, with the power density in the parting strip being several times higher than the power density in the shed zone, resulting in the parting strip remaining significantly warmer than the shed zone.
