A Singapore-based aerospace company has developed a combat drone capable of reaching supersonic speeds.
Kelley Aerospace unveiled their concept for an unmanned aerial vehicle (UAV) called the Arrow last week, according to Auto Evolution. The drone's capable of flying more than 2,600 nautical miles at mach 2.1, or 1,611 miles per hour. That means the drone can fly from Los Angeles to Tokyo in a little over three hours — all while breaking the sound barrier.
- Meh, looks like another mostly paper-based fantasy engineered purely to extract investment dollars. Where'e the engine going to come from?Nairn
- micro nuclear reactor inside the drone ..or nano solar cellsneverscared
- fueling tiny jetengine.neverscared
- concorde engenines were pretty small too compared to normal passenger flight and thats some time ago.neverscared
- tiny jet engines don't produce enough thrust, ask any model engineerhans_glib
- erm, where did you get the idea that Concorde engines were 'small'? They were at least twice as long as contemporary turbofans.Nairn
- ..and Concorde had four of them, which compared to a 737 with about the same/more passengers is twice as many, larger, engines.Nairn
