U\u00e7u\u015f s\u0131ras\u0131nda pencereden d\u0131\u015far\u0131 bakarken belki de u\u00e7ak pencerelerinin neden yuvarlak oldu\u011funu<\/p>\n

siz de d\u00fc\u015f\u00fcnm\u00fc\u015fs\u00fcn\u00fczd\u00fcr. Tabii ki bunu u\u00e7madan da d\u0131\u015far\u0131dan g\u00f6rmek m\u00fcmk\u00fcn.<\/p>\n

Evet u\u00e7ak pencereleri evlerimizdeki k\u00f6\u015feli pencerelerden farkl\u0131 olarak, k\u00f6\u015feleri yuvarlat\u0131lm\u0131\u015f<\/p>\n

Yuvarlak u\u00e7ak pencerelerinin estetik g\u00f6r\u00fcn\u00fcmleri asl\u0131nda \u00e7ok \u00f6nemli bir u\u00e7u\u015f emniyeti gereklili\u011fidir.<\/p>\n

Basit\u00e7e anlatmak gerekirse u\u00e7aklar\u0131 havada u\u00e7u\u015fun ortas\u0131nda par\u00e7alanmaktan korumaktad\u0131r<\/p>\n

yuvarlak pencereler.<\/p>\n

Uzay ve u\u00e7ak m\u00fchendisli\u011fi y\u0131llar boyunca u\u00e7aklar\u0131 daha y\u00fcksekten ve daha h\u0131zl\u0131 u\u00e7urmak i\u00e7in<\/p>\n

olmakta yani daha az s\u00fcrt\u00fcnme ile u\u00e7aklar daha y\u00fcksekten daha s\u00fcratli u\u00e7ulabilmekteydi. Fakat bu<\/p>\n

avantaj insanlar i\u00e7in pek uygun de\u011fildi. \u00c7\u00fcnk\u00fc 10.000 feet’i ge\u00e7en irtifalarda yetersiz kabin hava<\/p>\n

\u0130\u015fte bu nedenle u\u00e7a\u011f\u0131n g\u00f6vdesi kabin i\u00e7 bas\u0131nc\u0131n\u0131 destekleyecek bir silindir \u015feklinde geli\u015ftirilmeye<\/p>\n

De Havilland Comet, \u0130ngiliz De Havilland \u015firketi taraf\u0131ndan “d\u00fcnyan\u0131n ilk jet motorlu yolcu u\u00e7a\u011f\u0131”<\/p>\n

olarak tan\u0131t\u0131lan ve ilk u\u00e7u\u015funu 1949 y\u0131l\u0131nda ve ilk ticari u\u00e7u\u015funu May\u0131s 1952’de yapan yolcu<\/p>\n

Tasar\u0131mc\u0131lar kaza sebebinin k\u00f6\u015feli pencereler oldu\u011funu k\u0131sa s\u00fcrede buldular.<\/p>\n

Nerede bir k\u00f6\u015fe varsa orada, kabini bas\u0131n\u00e7lanan bir u\u00e7akta potansiyel bir zay\u0131f nokta mevcuttu.<\/p>\n

Yani bu her k\u00f6\u015feli pencerede d\u00f6rt adet zay\u0131f nokta olmas\u0131 anlam\u0131na geliyordu. K\u00f6\u015feli pencereler<\/p>\n
