The Falcon Hypersonic Technology Vehicle-2 (Falcon HTV-2) is the fastest plane ever built by human beings. It would fly from London to Sydney in less than an hour. Supersonic Concorde, by the way, could not fly at such a great speed. At the same time it would withstand temperatures of almost 2,000 degree C. This temperature is hotter than the melting point of steel.
The US Defense Agency will launch the Falcon HTV-2. First, they will set it on the back of a rocket. Then they will launch both into the space from an Air Force Base. The plan goes like this: engineers will launch the Falcon HTV-2. into the space on the back of a rocket; then they will detach the plane from the rocket; the plane Falcon will fly towards the Earth; engineers will guide and monitor its flight. The plane would fly at hypersonic speed of 13,000 mp/h. This speed is about 20 times the speed of sound.
The Falcon was born in 2003. It was born as part of a US military project. The project researched and built a special type of plane. The researchers wanted that the plane could reach any part of the world in less than an hour. They also wanted to use it for both military and civil purposes. The plane had already been tested in computer models.
The Falcon Hypersonic Technology Vehicle-2 would be mankind’s dream aircraft in the days to come.
ফ্যালকন হাইপারসনিক টেকনোলজি ভেহিকল–২ (Falcon HTV–2) হলো মানবজাতির নির্মিত সবচেয়ে দ্রুতগামী বিমান। এটি লন্ডন থেকে সিডনি পর্যন্ত এক ঘণ্টারও কম সময়ে উড়ে যেতে পারবে। অপরদিকে, অতিস্বরগতির কনকর্ড (Concorde) কখনোই এত উচ্চ গতিতে উড়তে পারত না। একই সঙ্গে এটি প্রায় ২০০০ ডিগ্রি সেলসিয়াস তাপমাত্রা সহ্য করতে পারবে। এই তাপমাত্রা ইস্পাতের গলনাঙ্কের চেয়েও বেশি।
মার্কিন প্রতিরক্ষা সংস্থা ফ্যালকন HTV–2 উৎক্ষেপণ করবে। প্রথমে তারা এটিকে একটি রকেটের পেছনে স্থাপন করবে। তারপর বিমান বাহিনীর ঘাঁটি থেকে রকেটসহ এটিকে মহাকাশে উৎক্ষেপণ করবে। পরিকল্পনাটি এমন: প্রকৌশলীরা ফ্যালকন HTV–2–কে রকেটের পেছনে বসিয়ে মহাকাশে পাঠাবেন; এরপর তারা রকেট থেকে বিমানটিকে আলাদা করবেন; ফ্যালকন বিমানটি পৃথিবীর দিকে উড়ে আসবে; প্রকৌশলীরা এর উড্ডয়ন নিয়ন্ত্রণ ও পর্যবেক্ষণ করবেন। বিমানটি ঘণ্টায় ১৩,০০০ মাইল বেগে উড়বে, যা শব্দের গতির প্রায় ২০ গুণ।
ফ্যালকনের জন্ম ২০০৩ সালে। এটি একটি মার্কিন সামরিক প্রকল্পের অংশ হিসেবে তৈরি হয়েছিল। সেই প্রকল্পে বিশেষ ধরনের একটি বিমান নিয়ে গবেষণা ও নির্মাণ করা হয়। গবেষকরা চেয়েছিলেন, এমন একটি বিমান তৈরি করতে যা বিশ্বের যেকোনো প্রান্তে এক ঘণ্টারও কম সময়ে পৌঁছাতে পারে। তারা এটিকে সামরিক ও বেসামরিক উভয় উদ্দেশ্যেই ব্যবহার করতে চেয়েছিলেন। বিমানটি ইতোমধ্যে কম্পিউটার মডেলে পরীক্ষিত হয়েছে।
ফ্যালকন হাইপারসনিক টেকনোলজি ভেহিকল–২ হবে আগামীর দিনে মানবজাতির স্বপ্নের বিমান।
