Merhaba merakl\u0131 minik pilotlar ve gelece\u011fin havac\u0131l\u0131k m\u00fchendisleri!

Kocaman, a\u011f\u0131r makineler… Yerden havalan\u0131yor, saatlerce g\u00f6ky\u00fcz\u00fcnde kal\u0131yor ve sonra da p\u00fcr\u00fczs\u00fczce yere iniyorlar. Sanki sihir gibi, de\u011fil mi?<\/p>\n\n\n\n

Asl\u0131nda bu sihir de\u011fil, tam anlam\u0131yla bilim! U\u00e7aklar\u0131n g\u00f6ky\u00fcz\u00fcnde kalmas\u0131n\u0131 sa\u011flayan \u00e7ok \u00f6zel bir g\u00fc\u00e7 var: Kald\u0131rma Kuvveti!<\/strong> Ama durun, hemen konuya dalmadan \u00f6nce, u\u00e7aklara etki eden t\u00fcm g\u00fc\u00e7leri bir tan\u0131yal\u0131m. \u00c7\u00fcnk\u00fc u\u00e7mak, sadece kald\u0131rma kuvvetiyle ilgili de\u011fil, bir tak\u0131m i\u015fi gibi!<\/p>\n\n\n\n

Bir u\u00e7a\u011f\u0131n g\u00f6ky\u00fcz\u00fcnde dans edebilmesi i\u00e7in d\u00f6rt ana kuvvetin uyumlu bir \u015fekilde \u00e7al\u0131\u015fmas\u0131 gerekiyor. Bu kuvvetleri bir futbol tak\u0131m\u0131n\u0131n oyuncular\u0131 gibi d\u00fc\u015f\u00fcnebiliriz. Her birinin ayr\u0131 bir g\u00f6revi var ve hepsi birlikte \u00e7al\u0131\u015ft\u0131\u011f\u0131nda ortaya harikalar \u00e7\u0131k\u0131yor!<\/p>\n\n\n\n

  1. Kald\u0131rma Kuvveti (Lift):<\/strong> \u0130\u015fte kahraman\u0131m\u0131z! U\u00e7a\u011f\u0131 yukar\u0131 do\u011fru iten, yer \u00e7ekimine meydan okuyan g\u00fc\u00e7 bu. Sanki g\u00f6r\u00fcnmez bir el u\u00e7a\u011f\u0131 yukar\u0131 do\u011fru kald\u0131r\u0131yor gibi d\u00fc\u015f\u00fcnebilirsiniz.<\/li>\n\n\n\n
  2. Yer\u00e7ekimi Kuvveti (A\u011f\u0131rl\u0131k):<\/strong> Yer\u00e7ekimi, her \u015feyi oldu\u011fu gibi u\u00e7aklar\u0131 da yere do\u011fru \u00e7eker. Bu, kald\u0131rma kuvvetinin yenmesi gereken en b\u00fcy\u00fck rakip. U\u00e7a\u011f\u0131n a\u011f\u0131rl\u0131\u011f\u0131 ne kadar fazlaysa, yer\u00e7ekimi de o kadar g\u00fc\u00e7l\u00fc \u00e7eker.<\/li>\n\n\n\n
  3. \u0130tme Kuvveti (Thrust):<\/strong> U\u00e7a\u011f\u0131 ileri do\u011fru hareket ettiren g\u00fc\u00e7. Motorlar ve pervaneler sayesinde olu\u015fur. \u0130tme kuvveti, u\u00e7a\u011f\u0131n h\u0131zlanmas\u0131n\u0131 ve hareket etmesini sa\u011flar.<\/li>\n\n\n\n
  4. S\u00fcr\u00fckleme Kuvveti (Drag):<\/strong> Hava direnci! U\u00e7ak havada ilerlerken hava molek\u00fclleri ona kar\u015f\u0131 koyar. Bu da s\u00fcr\u00fckleme kuvvetini olu\u015fturur. S\u00fcr\u00fckleme kuvveti, u\u00e7a\u011f\u0131n h\u0131z\u0131n\u0131 yava\u015flatmaya \u00e7al\u0131\u015f\u0131r.<\/li>\n<\/ol>\n\n\n\n

    Kald\u0131rma Kuvveti: U\u00e7u\u015fun Gizli Kahraman\u0131<\/strong><\/p>\n\n\n\n

    \u015eimdi gelelim esas o\u011flana, yani kald\u0131rma kuvvetine! Bu kuvvet nas\u0131l olu\u015fuyor dersiniz? \u0130\u015fin s\u0131rr\u0131, u\u00e7a\u011f\u0131n kanatlar\u0131n\u0131n \u00f6zel \u015feklinde sakl\u0131. U\u00e7ak kanatlar\u0131, \u00fcst taraf\u0131 bombeli, alt taraf\u0131 ise daha d\u00fcz olacak \u015fekilde tasarlan\u0131r. Bu \u00f6zel \u015fekle kanat profili (airfoil)<\/strong> diyoruz.<\/p>\n\n\n\n

    U\u00e7ak h\u0131zland\u0131k\u00e7a kanatlar havay\u0131 yararak ilerler. Kanad\u0131n \u00fcst\u00fcndeki bombeli y\u00fczey, havan\u0131n daha h\u0131zl\u0131 akmas\u0131na neden olurken, alt\u0131ndaki d\u00fcz y\u00fczeyde hava daha yava\u015f akar. \u0130\u015fte burada sihirli bir prensip devreye giriyor: Bernoulli Prensibi.<\/strong><\/p>\n\n\n\n

    Bernoulli Prensibi Ne Diyor?<\/strong><\/p>\n\n\n\n

    Daniel Bernoulli ad\u0131nda \u0130svi\u00e7reli bir bilim insan\u0131, ak\u0131\u015fkanlar\u0131n (s\u0131v\u0131lar ve gazlar) h\u0131z\u0131 ile bas\u0131nc\u0131 aras\u0131nda ilgin\u00e7 bir ili\u015fki oldu\u011funu ke\u015ffetmi\u015f. Bernoulli Prensibi k\u0131saca \u015funu s\u00f6yler: Ak\u0131\u015fkan\u0131n h\u0131z\u0131 artt\u0131k\u00e7a bas\u0131nc\u0131 d\u00fc\u015fer, h\u0131z\u0131 azald\u0131k\u00e7a bas\u0131nc\u0131 artar.<\/strong><\/p>\n\n\n\n

    \u015eimdi bunu u\u00e7ak kanatlar\u0131na uyarlayal\u0131m. Kanad\u0131n \u00fcst y\u00fczeyinde hava daha h\u0131zl\u0131 akt\u0131\u011f\u0131 i\u00e7in bas\u0131n\u00e7 d\u00fc\u015fer. Alt y\u00fczeyinde ise hava daha yava\u015f akt\u0131\u011f\u0131 i\u00e7in bas\u0131n\u00e7 artar. \u0130\u015fte bu bas\u0131n\u00e7 fark\u0131, kanad\u0131n alt\u0131nda daha y\u00fcksek, \u00fcst\u00fcnde daha d\u00fc\u015f\u00fck bir bas\u0131n\u00e7 olu\u015fturur. Bu da kanad\u0131 yukar\u0131 do\u011fru iten bir kuvvet yarat\u0131r: Kald\u0131rma Kuvveti!<\/strong><\/p>\n\n\n\n

    Sanki kanad\u0131n alt\u0131ndaki hava, “Yukar\u0131, yukar\u0131!” diye ba\u011f\u0131r\u0131yor ve kanad\u0131 yukar\u0131 do\u011fru itiyor gibi d\u00fc\u015f\u00fcnebilirsiniz. Ne kadar h\u0131zl\u0131 hareket ederse, kanatlar o kadar \u00e7ok kald\u0131rma kuvveti \u00fcretir.<\/p>\n\n\n\n

    Sadece Kanat \u015eekli Mi? Ba\u015fka Neler Kald\u0131rma Kuvvetini Etkiler?<\/strong><\/p>\n\n\n\n

    Kanat \u015fekli \u00e7ok \u00f6nemli olsa da, kald\u0131rma kuvvetini etkileyen ba\u015fka fakt\u00f6rler de var:<\/p>\n\n\n\n
