AMIL provides one-of-a-kind services in the qualification, certification, and evaluation of liquid deicing and anti-icing products for aircraft, as well as airport runway products, icephobic products (under development), and various other deicing and anti-icing strategies.

    1. Aircraft products
      Aircraft deicing/anti-icing fluids are certified in accordance with Aerospace Material Specification (AMS) 1424 (Type I deicing material) and 1428 (Type II, III and IV anti-icing material) and Aerospace (AS) 5900 and 5901.
      Tests conducted :

          • Aerodynamic flow-off of deicing/anti-icing fluids during simulated acceleration of aircraft take-off in a refrigerated wind tunnel (AS5900). Three take-off acceleration ramps are simulated :
            • High-speed take-off jet aircraft (High-Speed Ramp),
            • Medium-speed take-off aircraft (Middle-Speed Ramp),
            • Low-speed take-off aircraft (Low-Speed Ramp).
          • Anti-icing holdover time under various icing conditions such as freezing fog and light rime (AS5901).
          • Endurance time tests under the following winter conditions: freezing rain, freezing drizzle, freezing fog, and natural and artificial snow (ARP5485).
          • Viscosity measurement.
          • Physical and chemical properties, fluid stability tests, effect on materials, and environmental information.

      Lists of Qualified Fluids: Type I, Type II, Type III and Type IV.

    2. Runway products

      Assessment of solid and liquid products for airport runways is performed in accordance with Aerospace Material Specification (AMS) 1431 (Solid RDP) and 1435 (liquid RDP).Tests conducted :

          • Deicing performance according to standards :
            • AS6211 : Ice Penetration Test
            • AS6172 : Ice Undercutting Test
            • AS6170 : Ice Melting Test
          • Anti-icing holdover time in various types of freezing precipitation.
          • Skid/friction conditions.
          • Test Method for Catalytic Carbon Brake Disk Oxidation (AIR5567).
          • Physical and chemical properties, fluid stability tests, effect on materials, and environmental information.
  2. Icephobic products
    Icephobic products are assessed according to internal procedures that are proven and published in various scientific journals and international conferences.
    Tests conducted :

        • Centrifuge adhesion testing (CAT) to measure ice adhesion.
        • Comparative studies of ice accumulation.
        • Surface weathering and damage caused by UV and rain erosion.
        • Performance in freezing conditions (snow, freezing rain, sea spray, etc.).
        • Thermal behaviour in freezing conditions.
        • Wettability characterization.

     

     

  3. Assessment of behaviour under snowy and freezing conditions
    Structural icing assessment and deicing/anti-icing strategies are carried out by reproducing real-life conditions in the laboratory. The assessment is based on proven internal procedures published in various scientific journals and international conferences.
