Laboratory Viscosity Measurement of Thickened Aircraft Deicing/Anti-icing Fluids with a ViscometerAS9968A (Current)07/23/2021
This document describes a standard method for measuring the viscosity of thickened (AMS1428) Type II/III/IV Aircraft Deicing/Anti-icing Fluids. The determination of viscosity for a Non-Newtonian fluid is very sensitive to shear and differences in sample chamber geometry. Even slight differences can have a large effect on measurement results. The test parameters and associated error for this standard are applicable to the Brookfield LV viscometer. A Brookfield LV or equivalent viscometer shall be used. To be considered equivalent, an alternate viscometer must demonstrate statistically equivalent performance, i.e., accuracy and precision when testing thickened (AMS1428) fluids using the same test parameters and conditions.Test parameters and conditions outside of the ranges described within this standard may be used only if they meet minimum limits for precision and accuracy established for the Brookfield LV viscometer. To compare viscosities, the same test parameters and conditions

Equivalent Sand Grain Roughness Correlation for Aircraft Ice Shape Predictions2019-01-197806/10/2019
Many uncertainties in an in-flight ice shape prediction are related to convection heat transfer coefficient, which in turn depends on the flow, turbulence and laminar/turbulent transition models. The height of ice roughness element used to calculate the Equivalent Sand Grain Roughness height (ESGR) is a very important input of the turbulence model as it strongly influences the shape of the accreted ice. Unfortunately, for in-flight icing, the ESGR is unknown and generally calculated using semi-empirical models or empirical correlations based on a particular ice shape prediction code. Each ice shape prediction code is unique due to the models and correlations used and the numerical implementation. Ice roughness correlations do not have the same effect in each ice shape prediction code. A new approach to calculate the ESGR correlation taking into consideration the particularities of the ice shape prediction code is developed, calibrated and validated. This new approach derives a

Advanced Nanocomposite Low Adhesion Icephobic Coating for Aerospace Applications2019-01-199606/10/2019
Icing is a major safety issue for flight operations in the civil, defense and space sectors. Ice can form on critical components during takeoff/landing, or while in service, depending on prevailing weather conditions. Aircraft manufacturers relies on two different approaches to prevent ice buildup using an active anti-icing system to melt ice buildup or deicing chemicals/ice repellent surface to minimize the buildup ice. The use of active anti-icing systems offers good protection, however can add significant penalty to overall weight, energy consumption and cost. Aerospace industry is in need for an advanced ice repellent surface to effectively minimize ice buildup on critical components with no modification to existing design can provide significant relief to ice prone systems. In this paper, Oceanit will present its most advanced nanocomposite low ice adhesion icephobic coating technology that was developed and demonstrated for application on metallic surfaces to provide the lowest

Runway Deicing Product Anti/Deicing Performance Assessment: Review and Future Directions2019-01-197406/10/2019
Every winter, northern airport operations are disrupted by heavy snowstorms and freezing precipitations. A simple snow accumulation or a thin layer of ice can affect aircraft operations (take-off, landing and taxi), and increase the risk for passengers and crew members, by rendering the runway slippery. Any deficits in deicing operations can also lead to flight delays and even cancellations that cost a lot to the industry. In order to maintain the runway and taxiway in a safe and useable condition, airport authorities use mechanical tools, but also chemical products. Chemical products available on the market for use in airports are principally in solid forms and liquid form, and are denominated as Runway Deicing Product (RDP). All of the products used in airport should meet the technical requirements of one of the two Aerospace Materials Specifications (AMS) documents: the AMS1431D Compound, Solid Runway and taxiway Deicing/Anti-icing and the AMS1435C Fluid, Generic, Deicing/Anti-icing

Analysis of Influence of Snow Melting Agents and Soil Components on Corrosion of Decorative Chrome Plating2016-01-053904/05/2016
The dissolution and exfoliation of chromium plating specific to Russia was studied. Investigation and analysis of organic compounds in Russian soil revealed contents of highly concentrated fulvic acid. Additionally, it was found that fulvic acid, together with CaCl2 (a deicing agent), causes chromium plating corrosion. The fulvic acid generates a compound that prevents reformation of a passivation film and deteriorates the sacrificial corrosion effectiveness of nickel.

Evaluation of Different Ice Adhesion Tests for Mechanical Deicing Systems2015-01-213506/15/2015
A designer of a new mechanical ice protection system for airplanes needs to know how much and in which way he has to deform the surface to break off the ice. The ice adhesion strength is often used as a design value. Several methods have been published to measure the adhesive strength of ice. This paper analyzes the interface stresses created by those methods and discusses the way the adhesion strength is derived. A finite element method tool is used to provide insight into the stress state for different load cases. The implication of these illustrations is that equations which use only ultimate force and total interfacial area to calculate adhesion strength miss local stress concentrations and crack nucleation. Hence, the derived adhesion strength may not be comparable within different testing methods, because each testing procedure neglects different parameters like specimen size, substrate thickness and stiffness. In addition the ice adhesion strength is different if peel stress or

Developing a Novel Ice Protection System for Wind Turbine Blades Using Vibrations of Both Short and Long Wavelengths2015-01-208106/15/2015
Icing conditions in cold regions of the world may cause problems for wind turbine operations, since accreted ice can reduce the efficiency of power generation and create concerns regarding ice-shedding. This paper covers modelling studies and some experimental development for an ongoing ice protection system that provides both deicing and anti-icing actions for wind turbine blades. The modelling process contained two main sections. The first part involved simulation of vibrations with very short wavelength or ultrasonic guided waves (UGW) on the blade to determine optimal excitation frequency and transducer configuration. This excitation creates horizontal shear stress at the interface between ice and blade and focuses energy at the leading edge for de-bonding ice layers. The second modelling approach simulated the effects of vibrations with very long wavelength along with estimation of fatigue life due to harmonic forces to characterise the best parameters for shaker (s) mounted on

Microwave-Steam Based Road Deicing Vehicle Focused on Thin Ice Layers2015-01-050204/14/2015
For the thin ice on the road in winter, the traditional road deicing vehicle relies on mechanical and chemical methods for melting ice, which is inclined to damage the pavement and has insidious influence on environment. The thermal deicing vehicle has been adopted in recent years. Although the deicing method is available, the deicing efficiency is unacceptable while the energy consumption is huge. The study adopts the new idea of “bottom-to-top” for melting the intersection area between the road surface and the bottom ice layer by the microwave heating firstly and then cleaning them out using high pres. vapor cutting so as to save the cost of energy and enhance the traffic safety. First of all, the mathematical model of the melting process of the intersection of the pavement and the ice layer was established according to the microwave heating characteristics. Then the mechanism about the compatibility between the steam temperature, saturation and the upper surface of the ice was

Utilizing CFD Approach for Preeminent Assessment of Defroster Air Flow Distribution and Predicting Windscreen Deicing Behavior2014-01-068804/01/2014
Adequate visibility through the automobile windscreen is a critical aspect of driving, most often at very low temperatures when ice tends to be formed on the windscreen. The geometry of the existing defroster system needs to be improved in the vehicles, with the main aim of substantial increase in air mass flow reaching the windscreen through defroster nozzles and appropriate velocity distribution over the windscreen, while respecting all packaging constraints. The reason of this study is to investigate the windscreen deicing behavior of a vehicle by means of Computational Fluid Dynamics (CFD) with the main concern of improving deicing process by design an appropriate defroster. Two different defrosters with completely different geometry are considered for this purpose. A detailed full interior model of an existing vehicle is created via CAE tools. A transient simulation is performed and results are extracted to show how a proper design of the defroster will lead to considerable

Air-Data System Detects Aircraft IcingTBMG-1878512/01/2013
Michigan Aerospace Corporation (MAC) has begun work on a Phase I Small Business Innovation Research (SBIR) contract with NASA’s Langley Research Center. The contract, “RIDES: Raman Icing Detection System,” extends MAC’s present aircraft-based optical airdata system technology — which uses ultraviolet laser light to measure air speed, direction, temperature, and density — to also detect conditions aloft when ice is likely to form, enabling a multi-hazard sensing capability.
De-Icer Quantification and Phase Transition Detection by Raman Spectroscopy2013-01-210109/17/2013
Winter maintenance is based on the intervention of operating services, as well as the use of deicers. Each year, in France, thousands of tons of deicers are spread through runways and taxiways. On the airport sector, the main deicers are sodium or potassium acetates and formates. All these deicers aim to prevent ice formation (preventive strategy) and/or improve the ice melting of snow residual film (curative strategy) at temperatures below 0°C. The operating principle of these compounds is based on the lowering of the solution's freezing point once dissolved in water. The phase diagram's knowledge is predominant to determine the deicer's amount to be applied on the surface. It provides a way to optimize their amounts applied with respect to weather conditions, present or forecasted. The Center for Technical Studies of Equipment in East of France (CETE de l'Est) developed and implemented a method based on Raman spectroscopy to characterize aqueous solutions of airport de-icers.

Rotating Testing of a Low-Power, Non-Thermal Ultrasonic De-icing System for Helicopter Rotor Blades2011-38-009806/13/2011
Ultrasonic excitation has proven to provide ice interface transverse shear stresses exceeding the adhesion strength of freezer and wind tunnel ice to various metals, promoting instantaneous ice delamination. Prior proof-of-concept testing presented issues related to piezoelectric actuator cracking under ultrasonic tensile excitation, as well as actuator debonding from the host structure. The aim of this research is to provide solutions to the actuator reliability issues encountered during prior research and to perform rotor icing testing to validate the proposed solutions. Three different approaches are taken to solve the issues related with actuator failure during de-icing processes: custom-designed controllers to ensure the excitation of desired ultrasonic resonance modes, compression only driving of the actuator, and optimization of actuator thickness. The novel driving conditions and geometry of the actuation system is modeled using finite elements and tested at the Penn State

Dispersion of De-Icing Chemicals to the Areas Along the Runways at Oslo Airport Gardermoen2007-01-335109/24/2007
Oslo Airport Gardermoen is located on the largest unconfined groundwater aquifer in Norway and acts upon strict governmental regulations concerning groundwater balance and contamination of groundwater and surface waters. In the cold Norwegian winter climate, de-icing of aircrafts and runway systems is necessary for safety reasons. The aircraft de-icing fluids (type 1 and type 2) are based on propylene glycol (PG). Potassium Formate (PF) is used for de-icing of runways and taxiways. Aircraft de-icing takes place on remote de-icing platforms. At each platform there is a system for drainage of excess de-icing fluid, but some is passively dispersed from the aircraft body to the area along the runways and mix with snow. During melting, release of de-icers to the ground occurs. In such events the chemicals need to be biologically degraded in the unsaturated zone to meet the governmental requirements.
