கைபர்சொனிக் விமானம் இன்று பல நாடுகளில் பல ஆராச்சி நிறுவனங்களால் கணணியில் வெர்டுயல் மொடல் ஆக வடிவமைக்கப் பட்டு வருகிறது,இது இன்னும் ஒரு இருபது,முப்பது வருடங்களில் தொழில் நுட்ப ரீதியாக நிதர்சனமாகக் கூடியது. ஆனால் உலகத்தில் எண்ணை வளம், மாற்று எரிபொருள் போன்ற கரணிகளால் இவை முற்றிலுமாக வேறு வடிவங்களை எடுக்கலாம்.ஈற்றில் கொன்கோட்ட் கைவிடப்பட்டதைப் போல் இந்த முயற்சிகளும் எதுவித பயனை அழிக்காமலும் இருக்கலாம்.ஆனால் இராணுவ ரீதியாக இது மேற்கத்திய நாடுகளுக்கு உலகை தமது கைக்குள் வைத்திருக்க மிகப் பெரிய வல்லமையை வழங்கும்.

Hypersonic flight at speeds 5 to 12 times the speed of sound (Mach 5 to Mach 12) is one such area of interest to the commercial and defense communities.
At Lawrence Livermore National Laboratory, aerospace engineer Preston Carter has invented a concept for a next-generation hypersonic aircraft, dubbed HyperSoar, that could fly efficiently, economically, and cleanly.
Flying at Mach 10 (3 kilometers per second), HyperSoar could reach any point on the globe within two hours. (The fastest military plane, the SR-71, flies between Mach 3 and Mach 4, while the commercial Concorde only reaches Mach 2.) HyperSoar would also have twice the fuel efficiency of commercial airliners, be three to five times more efficient in putting satellites in space than today's launch systems, and use liquid hydrogen fuel, which produces simple water vapor when burned.
HyperSoar-a concept-development project funded through Livermore's Physics Directorate and the Laboratory Directed Research and Development Program-could transport people or cargo, strike enemy targets, or help put satellites into space. "The fact that HyperSoar has many potential uses is key," says Carter. "Developing an entirely new aircraft is expensive. However, if there is a large market for such an aircraft, the cost per plane goes down. It's like the difference between a 747 and the Stealth bomber. There are hundreds of Boeing 747s being used by commercial airline companies, airfreight companies, and so on. But the only market for the Stealth is the military, which only needs a few. That's why you'll never see a Stealth being built for much less than they cost today."
