WIND TUNNEL TESTING
Wind Tunnel Testing of the effects of Cilajet Aero was essential to evaluate if Cilajet coatings reduce drag on an aircraft. Below is a table with CDWA from the comparable test points. According to Jack Ross, UWAL Business Manager/Electrical Engineer: “You can see that the Cilajet case did not negatively affect drag. In fact, the drag is appreciably reduced.”
REDUCTION IN FUEL CONSUMPTION AND EMISSIONS
The purpose of this analysis is to present equations and assumptions required to estimate fuel savings and emissions from an arbitrary jet aircraft and to apply these methods and principles to several jet transport type aircraft. According to Dr. Willem A.J. Anemaat, President of DAR Corporation, based on the drag coefficient data from the UWAL Wind Tunnel testing, as the table below shows, “the sealant increases the performance of the aircraft and reduces the emissions of the aircraft over the same range.”
CILAJET AERO INTERACTION WITH AIRCRAFT DEICING/ANTI-ICING FLUIDS
Aircraft operators rely on the use of deicing/anti-icing fluids during winter operations to provide a limited period of protection against frozen or freezing precipitation while the aircraft is on the ground. The protection time can be estimated using fluid-specific holdover time guidelines that are published by the Federal Aviation Administration (FAA) and Transport Canada. Recently, aircraft operators have expressed interest in the use of after‐market coatings on aircraft surfaces for various purposes, including appearance enhancement, fuel savings, and ice shedding. The coatings may be designed to have hydrophilic or hydrophobic properties, and therefore, the interaction of these coatings with deicing/anti-icing fluids and their associated holdover times is unclear. Since aircraft coatings may affect fluid wetting capability and resulting fluid thickness, they could affect a fluid’s holdover time protection. Therefore, the interaction of aircraft surface coatings and aircraft deicing/anti-icing fluids should be evaluated with respect to holdover time performance and aerodynamic performance. In addition, test methods are available to help characterize the various aircraft surface coating properties, including durability, hardness, weathering, effect on aerodynamic drag, ice adhesion, ice accumulation, contact angle, and thermal conductivity.
The Type I Fluid used in Cilajet Aero testing was Chemco Inc. ChemR EG I. The compatibility test results show that Cilajet Aero “clearly has an effect on the wettability of the surface… the Type I fluid wets and spreads on the plates without Cilajet Aero but does not wet the ones covered with Cilajet Aero.”
The Type IV Fluid used in Cilajet Aero testing was Dow Chemical Co. UCAR FlightGuard AD-49. The Cilajet Aero “has no negative effect on the anti-icing protection time for Type IV PG based fluid against freezing for precipitation.”
ACCELERATED LIFE TESTING
CASS Test — Copper-Accelerated Acetic Acid Salt Spray (Fog) Test (ASTM B 368, B 117)
Method B 368. This test is used to determine corrosion resistance of various aluminum alloys. It is also used for testing of chromium plating on zinc and steel die castings.
It is performed using a standard ASTM B 117 salt fog cabinet, but the fog solution is mixed and acidified with acetic acid to a pH between 3.1 and 3.3. Copper chloride is then added to the salt solution. The solution is atomized as a fog into the cabinet which is maintained at 120F (49C).
“We have never seen results this amazing in 65 years in the chrome plating industry.”-This is what chrome plating companies are saying about Cilajet!
