Combustion occurs in an open chamber akin to a giant afterburner, where liquid fuel is injected or solid fuel is ablated from the chamber's sides [sources: Ashgriz; Encyclopaedia Britannica; SPG; Ward]. Ramjets' speed limitations gradually inspired hybrid engines that could fly at lower ...
In order for a floating object to stay still in a fast-moving part of the river, it would need to be anchored or propelled against the flow of the water. This is essentially what an acoustic levitator does, using sound moving through a gas in place of water. By placing a reflector ...
Just as water squeezed through a narrow pipe accelerates dramatically into a fast jet (think of what happens in a water pistol), the tapering design of the exhaust nozzle helps to accelerate the gases to a speed of over 2100 km/h (1300 mph). So the hot air leaving the engine at the ...
The short answer is that it depends on where you are. But in general, it is a speed that exceeds about 1200 km/h or 750 mph. If you’re capable of going this fast, you will be breaking the sound barrier, and people for miles around will be hearing about it! We have written many...
Boeing was competing for a supersonic transport contract in 1965, at about the same time the 747 was conceived, and Pan Am founder and chairman Juan Trippe believed that the big subsonic jets would end up as freighters and that the SST would replace the 747 on passenger routes. Trippe was...
In 2016, a team of engineers and adventurers will travel to the South African desert and attempt to become the first people to drive a car at 1,000mph. The British-made vehicle, Bloodhound SSC, is designed to smash the current world land-speed record of
The top speed for a 747 is about 570 miles per hour (mph), and this flight topped out at 825 mph.A British Airways plane has broken the record for fastest subsonic flight—by going faster than the speed of sound. The flight from New York to London arrived almost two hours early after...

These tunnels are categorized by their characteristics, such as the wind speed they generate in the test section. Subsonic wind tunnels test objects with airflows of less than 250mph (402 kph). Transonic tunnels cover tunnels cover a wind speed range of 250mph to 760mph (1,223 kph). ...
