Turboelektrik Adaptif Motor nedir?<\/b><\/p>\n

Astro Mechanica’n\u0131n geli\u015ftirdi\u011fi bu motor, geleneksel turbojet ve turbofan motorlar\u0131n\u0131n \u00f6zelliklerini birle\u015ftiriyor<\/strong>. Elektrikli ara\u00e7 motor teknolojisinden ilham al\u0131narak tasarlanan bu sistem, bir turbojenerat\u00f6r<\/strong> ile elektrik \u00fcretiyor ve bu elektrik, kompres\u00f6r\u00fc ve turbofan\u0131 ba\u011f\u0131ms\u0131z olarak \u00e7al\u0131\u015ft\u0131ran y\u00fcksek performansl\u0131 elektrik motorlar\u0131na g\u00fc\u00e7 sa\u011fl\u0131yor. Bu yenilik\u00e7i yap\u0131 sayesinde motor, s\u0131k\u0131\u015ft\u0131r\u0131lan hava miktar\u0131n\u0131 kontrol ederek hem yak\u0131t verimlili\u011fini art\u0131r\u0131yor hem de h\u0131z performans\u0131n\u0131 optimize ediyor.<\/p>\n

Bu kula\u011fa karma\u015f\u0131k gelebilir, ancak asl\u0131nda olduk\u00e7a dahiyane bir y\u00f6ntem<\/strong>; fan ve kompres\u00f6r bile\u015fenlerini ay\u0131r\u0131yor ve kompres\u00f6r\u00fc bug\u00fcn elektrikli ara\u00e7 pazar\u0131nda kullan\u0131lanlara benzer y\u00fcksek performansl\u0131 elektrik motorlar\u0131yla ba\u011f\u0131ms\u0131z bir \u015fekilde mekanik olarak \u00e7al\u0131\u015ft\u0131r\u0131yor.<\/p>\n

\u0130lk ate\u015fleme testi umut vadediyor<\/b><\/p>\n

<\/span> Astro Mechanica, ge\u00e7ti\u011fimiz ay\u0131n ortalar\u0131nda motorun Gen3<\/strong> versiyonunun y\u00fczde 30<\/strong> g\u00fc\u00e7le ilk s\u0131cak ate\u015fleme testini ba\u015far\u0131yla tamamlad\u0131<\/strong>. Bu test, teknolojinin ger\u00e7ek d\u00fcnyada uygulanabilirli\u011fi i\u00e7in \u00f6nemli bir d\u00f6n\u00fcm noktas\u0131 olarak dikkat \u00e7ekiyor. Motor, farkl\u0131 u\u00e7u\u015f ko\u015fullar\u0131na uyum sa\u011flayabilmek i\u00e7in \u00fc\u00e7 farkl\u0131 modda \u00e7al\u0131\u015f\u0131yor: <\/figure>\n
    \n
  • Mod<\/strong> 1: Bu modda motor, herhangi bir aktif yanma ger\u00e7ekle\u015ftirmez. Elektrik motoru, \u015firketin “blisk” olarak adland\u0131rd\u0131\u011f\u0131 ve kompres\u00f6r ile turbofan i\u015flevini birle\u015ftiren bir bile\u015feni \u00e7al\u0131\u015ft\u0131r\u0131yor. Blisk, geleneksel fan b\u0131\u00e7aklar\u0131ndan farkl\u0131 olarak daha kompakt ve hafif bir tasar\u0131ma sahip<\/li>\n
  • Mod 2<\/strong>: Bu mod, turbojet yanmas\u0131n\u0131 devreye sokuyor. Ancak geleneksel turbojetlerin aksine, motorun kompres\u00f6r\u00fc egzoz gazlar\u0131na ba\u011fl\u0131 de\u011fildir. Bunun yerine kompres\u00f6r, elektrik motorlar\u0131yla y\u00fcksek h\u0131zda \u00e7al\u0131\u015ft\u0131r\u0131larak yanma i\u00e7in gereken havay\u0131 sa\u011fl\u0131yor. Dahiyane bir detay!<\/li>\n
  • Mod 3<\/strong>: Bu mod, motorun tamamen yak\u0131tla \u00e7al\u0131\u015ft\u0131\u011f\u0131 ve hareketli par\u00e7alar\u0131n devre d\u0131\u015f\u0131 kald\u0131\u011f\u0131 bir yap\u0131 sunuyor. Ramjetlerde g\u00f6rd\u00fc\u011f\u00fcm\u00fcz “Ram Pressure” ad\u0131 verilen bir fiziksel etkiyle, u\u00e7ak y\u00fcksek h\u0131zlarda atmosferden gelen hava bas\u0131nc\u0131n\u0131 kullanarak yanma ger\u00e7ekle\u015ftirebilir.<\/li>\n<\/ul>\n

    Bu s\u0131ralama olduk\u00e7a \u00f6nemli, zaten tek bir \u00fcnitede bunu yapt\u0131\u011f\u0131 i\u00e7in bu motor konu\u011fumuz oluyor.<\/p>\n

    Geleneksel turbojet motorlar, sava\u015f u\u00e7aklar\u0131nda g\u00f6rd\u00fc\u011f\u00fcm\u00fcz gibi, egzoz gazlar\u0131n\u0131 kullanarak kompres\u00f6r fan\u0131n\u0131 d\u00f6nd\u00fcr\u00fcr ve havay\u0131 i\u00e7eri \u00e7eker. Daha fazla egzoz gaz\u0131, daha y\u00fcksek h\u0131z anlam\u0131na gelir. Bu motorlar s\u00fcpersonik h\u0131zlarda olduk\u00e7a verimli \u00e7al\u0131\u015fsa da, d\u00fc\u015f\u00fck h\u0131zlarda ciddi s\u0131k\u0131nt\u0131lar ya\u015far. Turbojetler, verimli bir yanma i\u00e7in yeterli havay\u0131 s\u0131k\u0131\u015ft\u0131rmakta zorlan\u0131r ve yak\u0131t\u0131n b\u00fcy\u00fck bir k\u0131sm\u0131n\u0131 israf eder.<\/p>\n

    <\/span> Bunun en \u00e7arp\u0131c\u0131 \u00f6rneklerinden biri, 1976-2003 y\u0131llar\u0131 aras\u0131nda kullan\u0131lan Concorde s\u00fcpersonik yolcu u\u00e7a\u011f\u0131d\u0131r. Concorde, yak\u0131t verimsizli\u011fiyle \u00fcnl\u00fcyd\u00fc; yaln\u0131zca kap\u0131dan piste taksi yapmak i\u00e7in yakla\u015f\u0131k 2 ton yak\u0131t harc\u0131yordu. Bu, d\u00fc\u015f\u00fck h\u0131zlarda turbojet motorlar\u0131n\u0131n ne kadar verimsiz oldu\u011funu a\u00e7\u0131k\u00e7a ortaya koyuyor. <\/figure>\n

    Turbofan motorlar ise d\u00fc\u015f\u00fck h\u0131zlarda daha b\u00fcy\u00fck hava k\u00fctlelerini hareket ettirerek u\u00e7aklar\u0131 verimli bir \u015fekilde ileriye ta\u015f\u0131mak i\u00e7in tasarlanm\u0131\u015ft\u0131r. Ancak y\u00fcksek h\u0131zlarda, optimize edilmemi\u015f b\u00fcy\u00fck fanlar\u0131n yaratt\u0131\u011f\u0131 aerodinamik s\u00fcr\u00fcklenme, verimlilik ve operasyonel sorunlara da yol a\u00e7\u0131yor.<\/p>\n

    Maliyet etkin bir yakla\u015f\u0131m<\/b><\/p>\n

    <\/span> Sava\u015f u\u00e7aklar\u0131 veya geleneksel u\u00e7ak motorlar\u0131nda en \u00f6nemli unsur maliyet. Mesela Boeing 737 MAX’de bulunan CFM LEAP-1B motoru, motor ba\u015f\u0131na yakla\u015f\u0131k 14 milyon dolara mal oluyor. Astro Mechanica, s\u00fcpersonik yetene\u011fe sahip turboelektrik adaptif motorlar\u0131n\u0131n daha ucuz olaca\u011f\u0131n\u0131, hareketli par\u00e7a say\u0131s\u0131n\u0131n az olmas\u0131 nedeniyle bak\u0131m\u0131n da ucuz olaca\u011f\u0131n\u0131 iddia ediyor. Hatta firma, bu motoru geleneksel jet yak\u0131t\u0131ndan \u00e7ok daha ucuz olan ve yak\u0131ld\u0131\u011f\u0131nda y\u00fczde 30 daha az CO2 \u00fcreten s\u0131v\u0131 do\u011fal gazla (LNG) \u00e7al\u0131\u015facak \u015fekilde tasarl\u0131yor. Firmaya g\u00f6re e\u011fer ikonik Concorde, bu motoru kullan\u0131yor olsayd\u0131 y\u00fczde 61 daha fazla menzile sahip olacakt\u0131. <\/figure>\n<\/p>\n
