• Utilizes Forced Air
- To remove loose accumulations
• With or without fluid
• Most often will be followed by
-Heated Deicing Fluid
-Or, Cold Anti-Icing Fluid
• Significantly reduces glycol consumption
• Four methods
-Forced Air
-Forced Air, plus Fluid Injection
-Fluid Over Forced Air
-Fluid Only
• Protected under license for:
-use of Williams, "Plurity of Fluid" Patent
-use of USAF, "Air Nozzle & Systems" Patent
|
• Researched by Wright Labs at Wright Patterson Air Force Base
• Access to U.S.A.F. scientists & facilities
• Discovered that correct Air
- Velocity - breaks coverage loose
- Volume - moves coverage away
• The key is in the delivery nozzle design
• USAF patented a
-sub-sonic, axisymmetrical, non-convergent, non flared, perfectly choked nozzle
• Provides Forced Air
- Speed of 800+ mph
- 1,350 cfm
- 11 psi
• Nozzle Diameter of 2 inches
• Air Source is a "continuos duty" rated blower
• Located at enclosed cab for max efficiency
• Approved by Boeing & USAF |
