Wings

A wing is a type of fin that produces lift while moving through air or some other fluid. Accordingly, wings have streamlined cross-sections that are subject to aerodynamic forces and act as airfoils. A wing's 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 orders of magnitude greater than the total 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 foils, such as hydrofoils. Hydrodynamics is the governing science, rather than aerodynamics. Applications of underwater foils occur in hydroplanes, sailboats and submarines. more »

Taufan ribut menyambar…lenyaplah perhitungan…
Gema kebebasan,menggegar Romania…

Lebar ufuk harapan,dilanda haloba kuasa..
Bahang Romania,merah darah kepunahan…

Hancur jua akhirnya,dalang-dalang kuku besi…
Teori domino,melanggar bumi gelora…

Katakan padaku..erti kedamaian sebenar..
Tanpa Keangkuhan…oh..Romania…

Padamkanlah bara api kemusnahan..
Hentikanlah sandiwara keangkuhan…

Oh..wujudkanlah..oh…kedamaian…
Oh..ciptakanlah…oh kedamaian…oh Romania…

Hancur jua akhirnya,dalang-dalang kuku besi…
Teori domino,melanggar bumi gelora…

Katakan padaku..erti kedamaian sebenar..
Tanpa Keangkuhan…oh..Romania…

Padamkanlah bara api kemusnahan..
Hentikanlah sandiwara keangkuhan…

Oh..wujudkanlah..oh…kedamaian…
Oh..ciptakanlah…oh kedamaian…

Oh..wujudkanlah..oh…kedamaian…
Oh..ciptakanlah…oh kedamaian…oh Romania…
