X-66A هي طائرة X تهدف تحديدًا إلى مساعدة الولايات المتحدة على تحقيق هدف صافي انبعاثات غازات الاحتباس الحراري بحلول عام 2050. لبناء X-66A ، ستعمل Boeing مع وكالة ناسا لتعديل طائرة MD-90 ، وتقصير جسم الطائرة واستبدال أجنحتها ومحركاتها. سيكون للطائرة التجريبية الناتجة أجنحة طويلة ورفيعة مع محركات مثبتة أسفلها ومجموعة من دعامات الديناميكية الهوائية للدعم. يُعرف التصميم ، الذي قدمته شركة Boeing لمشروع ناسا للطيران المستدام ، باسم جناح Transonic Truss-Braced Wing. الائتمان: ناسا
حددت القوات الجوية الأمريكية مشروع Flight Demonstrator المستدام ، وهو تعاون بين NASA و Boeing ، باسم X-66A. يهدف المشروع إلى تطوير تصميم طائرة ذات ممر واحد أكثر استدامة ، مما يساهم في تحقيق هدف صافي انبعاثات غازات الاحتباس الحراري للطيران بحلول عام 2050.
قالت ناسا وبوينغ يوم الإثنين إن الطائرة التي تم إنتاجها من خلال مشروع الطيران المستدام التابع للوكالة قد تم تحديدها من قبل القوات الجوية الأمريكية على أنها X-66A.
تسعى طائرة X الجديدة إلى إعلام جيل جديد محتمل من الطائرات ذات الممر الواحد الأكثر استدامة – العمود الفقري لشركات الطيران حول العالم. من خلال العمل مع وكالة ناسا ، ستقوم شركة Boeing ببناء واختبار وتطير طائرة تجريبية واسعة النطاق بأجنحة رفيعة وطويلة للغاية مثبتة بدعامات قطرية ، تُعرف باسم مفهوم Transonic Truss-Braced Wing.
“في ناسا ، لا تركز أعيننا على النجوم فحسب ، بل تركز أيضًا على السماء. قال بيل نيلسون ، مدير ناسا ، “إن برنامج” عرض الطيران المستدام “يبني على جهود ناسا الرائدة عالميًا في مجال الطيران والمناخ. “ستساعد X-66A في تشكيل مستقبل الطيران ، حقبة جديدة تكون فيها الطائرات أكثر اخضرارًا ونظافة وهدوءًا ، وتخلق إمكانيات جديدة للطائرات العامة والصناعات الأمريكية على حد سواء.”
X-66A هي أول طائرة X تركز بشكل خاص على مساعدة الولايات المتحدة على تحقيق هدف صافي انبعاثات غازات الاحتباس الحراري ، والذي تم توضيحه في خطة العمل المناخية للطيران في الولايات المتحدة للبيت الأبيض.
قال بوب بيرس ، المدير المساعد لمديرية مهام أبحاث الطيران في ناسا ، الذي أعلن عن التعيين في المعهد الأمريكي للملاحة الجوية والملاحة الفضائية منتدى الطيران في سان دييغو، “من خلال هذه الطائرة التجريبية ، نهدف إلى إظهار أنواع تقنيات توفير الطاقة وتقليل الانبعاثات التي تحتاجها صناعة الطيران.”
سعت ناسا وبوينغ للحصول على تصنيف X-plane بعد فترة وجيزة من إعلان الوكالة عن جائزة مشروع الطيران المستدام في وقت سابق من هذا العام، يمنح سلاح الجو حالة X-plane لبرامج التطوير التي تهدف إلى إنشاء تكوينات طائرات تجريبية ثورية، التعيين مخصص لطائرات البحث. مع استثناءات قليلة ، تهدف طائرات X إلى اختبار التصاميم والتقنيات التي يمكن اعتمادها في تصميمات الطائرات الأخرى ، وليس العمل كنماذج أولية للإنتاج الكامل.
قال تود سيترون ، كبير مسؤولي التكنولوجيا في بوينج: “نحن فخورون للغاية بهذا التصنيف ، لأنه يعني أن الطائرة X-66A ستكون التالية في سلسلة طويلة من الطائرات التجريبية المستخدمة للتحقق من صحة التصاميم المبتكرة التي غيرت الطيران”، “من خلال الدروس المكتسبة من التصميم والبناء واختبار الطيران ، ستكون لدينا فرصة لتشكيل مستقبل الطيران والمساهمة في إزالة الكربون من الفضاء.”
بالنسبة للطائرة X-66A ، قدمت القوة الجوية التعيين للطائرة التي تتحقق من صحة التقنيات الخاصة بتكوين Transonic Truss-Braced Wing الذي ، عند دمجه مع التطورات الأخرى في أنظمة الدفع ، والمواد ، وهندسة الأنظمة ، يمكن أن ينتج عنه ما يصل إلى 30٪ استهلاك أقل للوقود وانبعاثات أقل مقارنة بالطائرة الأفضل في فئتها اليوم.
نظرًا لاستخدامها المكثف، تمثل الطائرات ذات الممر الواحد اليوم ما يقرب من نصف انبعاثات الطيران في جميع أنحاء العالم، إن إنشاء تصميمات وتقنيات لنسخة أكثر استدامة من هذا النوع من الطائرات له تأثير عميق على الانبعاثات.
يعود تاريخ ناسا مع تسمية الطائرة X إلى أربعينيات القرن الماضي ، عندما قامت الوكالة التي سبقتها ، اللجنة الاستشارية الوطنية للملاحة الجوية (NACA) ، بإنشاء برنامج تجريبي للطائرات بالاشتراك مع القوات الجوية والبحرية الأمريكية. X-66A هي الأحدث في سلسلة طويلة من طائرات ناسا إكس، بالإضافة إلى ذلك ، قدم مركز أرمسترونج لأبحاث الطيران التابع لوكالة ناسا في إدواردز بولاية كاليفورنيا الخبرة الفنية والدعم للعديد من طائرات X الإضافية.
بالنسبة إلى برنامج عرض الطيران المستدام ، أبرمت وكالة ناسا اتفاقية قانون الفضاء الممول مع شركة بوينج ، والتي من خلالها ستستثمر الوكالة 425 مليون دولار على مدار سبع سنوات ، بينما ستساهم الشركة وشركاؤها بالجزء المتبقي من التمويل ، والمقدر بحوالي 725 مليون دولار. ستساهم ناسا أيضًا بالخبرات والمرافق الفنية.
يُعد مشروع “عارض الطيران المستدام” نشاطًا في إطار برنامج أنظمة الطيران المتكامل التابع لوكالة ناسا وعنصرًا رئيسيًا في الشراكة الوطنية للطيران المستدام التابعة للوكالة ، والتي تركز على تطوير تقنيات طيران مستدامة.

But he’s tryiong none the less. I’ve been using WordPress on a variety of websites for
about a year and am concerned about switching to another platform.

You might peek at Yahoo’s home page and watch how they write post headlines to
grab viewers to open the links. You might try adding a video or
a related picture or two to grab readers excited about what

Hello would you mind stating which blog platform you’re working
with? I’m planning to start my own blog soon but I’m having
a difficult time choosing between BlogEngine/Wordpress/B2evolution and Drupal.
