အသံထက္ ၆ ဆ ျမန္ ေလယ်ဥ္ပ်ံ စမ္းသမ္းစဥ္ပ်က္က်

ဒီေန ့ထူးျခားတဲ့သတင္းတပုုဒ္ကေတာ့ အသံထက္ ၆ ဆျမန္တဲ့ ဆူပါေလယ်ဥ္ပံ်  လိုုင္းစီးသူ လိုု ့အမည္ေပးထားတဲ့ X-51ကိုု စမ္းသပ္ ေမာင္းႏွင္စဥ္  ပ်က္က်သြားပါတယ္။ ဘီ ၅၂ ေလယ်ဥ္ပ်ံက ျဖဳတ္ခ်လိုုက္ျပီး တမိနစ္အတြင္းမွာ ပစၥဖိတ္သမုုဒရာအတြင္း ပ်က္က်သြားတာလိုု ့သိရပါတယ္။ ဒီေလယ်ဥ္ပ်ံဟာ တမိနစ္ကိုု မိုုင္ ၃၆၀၀ သြားနိင္ဖုုိ ့ရည္ရြယ္ထားတယ္။ ဒီစီမံကိန္းေအာင္ျမင္ခဲ့ရင္ ယ်ဥ္ပ်ံဟာ နယူးေယာက္ကေန လန္ ဒန္ ကိုု တနာရီေတာင္မၾကာဘူးလိုု ့ဆိုုပါတယ္။

The U.S. Air Force says its most ambitious test of its X-51 WaveRider hypersonic aircraft ended in failure less than a minute after launch on Tuesday, due to a flaw in one of the craft's control fins. The X-51 broke apart after it was dropped from a B-52 bomber, with pieces falling into the Pacific Ocean, a spokesman for the project told me today.
If the test had proceeded as planned, the Boeing-built X-51 would have shot through the sky for a five-minute flight at a speed of up to 3,600 mph (5,800 kilometers per hour), or six times the speed of sound. Instead, the Air Force is going back to the drawing board.
Hypersonic scramjet propulsion has been widely touted as eventually opening up the way for flights between London and New York in less than an hour. But in reality, the first application is more likely to come in the form of super-fast cruise missiles. (Scramjet is a short term for "supersonic combustion ramjet," and there have been many efforts through the years to perfect scramjet-powered aircraft.)
