WitrynaSurface roughness was measured before impact icing using a Bruker Dektak XT Stylus Profilometer (Sty Prof). Meas-urements were conducted using a 12.5 m tip at a vertical range of 65.5 m with an applied force of 3 mg. Data were collected over a 1.0 mm length at a resolution of 0.056 m/point. http://yadda.icm.edu.pl/yadda/element/bwmeta1.element.baztech-4c407844-2368-4a1d-aa49-0ceab4484b01

WitrynaIcing. Icing occurs if precipitation aggregates on the aircraft or at or within parts of it. There are several impact mechanisms. The dominant mechanism occurs when supercooled liquid water impinges on the aircraft and freezes instantaneously. ground icing. airframe icing; and engine icing. Normally, forecasts of icing are for airframe … WitrynaThe subject of the present paper is the applicability of hydrophobic surfaces for passive anti-icing protection. The experiments were focused on freezing droplets and on various droplet impingement and deformation scenarios. Droplet impact was investigated using high-speed camera for surfaces with different physico-chemical properties. hey robin tell me a joke

Witryna10 lut 2024 · Ice accumulation and adhesion can problematically occur on many engineering systems, such as electrical power networks, wind turbines, communication towers, and aircraft. An optional solution to these icing problems is the use of surfaces/coatings with low ice adhesion properties: Icephobic surfaces. Icephobic … Witryna12 kwi 2024 · Wind turbines operating in cold regions are prone to freezing in winter, which can affect their performance and safety. To resolve this situation, the development of blade anti-icing technology has attracted widespread attention. In this study, a type of biochar/polypyrrole coating was obtained through synthesis on the surface of biochar. … WitrynaThe low-power, nonthermal ultrasonic de-icing concept is investigated under impact-icing conditions in an icing wind tunnel. In this research effort, ultrasonic actuator disks excite isotropic plates and airfoil-shaped structures that are representative of helicopter leading-edge protection-cap shapes. Off-the-shelf ultrasonic actuators are ... hey rosetta
