Phoenix Wings
The Phoenix Wings ( uk, Крила Фенікса) are a volunteer organization that financially assists the Ukrainian Army and collects donations to support it. It was established by the Ukrainian activist Yury Biryukov (volunteer), Yury Biryukov on March 27, 2014. Tetiana Rychkova took a significant role in organization development. Activity Phoenix Wings arose as an attempt to provide support to the Armed Forces of Ukraine following heavy losses suffered during the early stages of the Russo-Ukrainian War. Phoenix Wings mainly deals with technical support of the Armed Forces of Ukraine, but also delivers medicine to the wounded during the fighting, carries out restoration of Ukrainian military buildings, and so on. The organization is also involved in the restoration of aircraft belonging to the Armed Forces of Ukraine. They helped to repair the aircraft AN-26, so the plane returned to the ranks of the Ukrainian army. The need for it has become particularly acute after the sep ...

Wings Phoenix
A wing is a type of fin that produces Lift (force), lift while moving through air or some other fluid. Accordingly, wings have Streamlines, streaklines, and pathlines, streamlined Cross section (geometry), cross-sections that are subject to aerodynamic forces and act as airfoils. A wing's Aerodynamics, aerodynamic efficiency is expressed as its lift-to-drag ratio. The lift a wing generates at a given speed and angle of attack can be one to two order of magnitude, orders of magnitude greater than the total drag (physics), drag on the wing. A high lift-to-drag ratio requires a significantly smaller thrust to propel the wings through the air at sufficient lift. Lifting structures used in water include various Foil (fluid mechanics), foils, such as hydrofoils. Hydrodynamics is the governing science, rather than aerodynamics. Applications of underwater foils occur in Hydroplane (boat), hydroplanes, sailboats and submarines. Etymology and usage For many centuries, the word "wing", fr ...
