Can you imagine flying from Los Angeles to Sydney in just 6 hours instead of 15? Or New York City to London in a blazing fast 3 hours rather than the typical 7? For those who value extreme velocity in air travel, supersonic flight makes such journeys possible.
So which nations possess the advanced expertise today to develop aircraft able to fly faster than the speed of sound? We rocket through supersonic capabilities of the US, Russia, Europe and Asia – past, present and future!
Strap yourself in, aviation geek…this ride across 50+ years of innovation history will be fast and furious!
What Exactly is Supersonic Flight?
Simply put, supersonic refers to speeds faster than the speed of sound which is 767 mph (1,230 km/hr) at sea level. Air reacts differently to objects zipping past this Mach 1 barrier – it compresses suddenly causing the loud and distinct ‘sonic boom‘ sound.
At such blistering paces, advanced aerodynamics, special materials, powerful engines and complex flight control systems are needed to ensure stability, efficiency and safety.
Since 1947 when Chuck Yeager first ‘broke‘ the sound barrier flying the Bell X-1, exclusive countries leading in science and technology have progressed supersonic aviation. Let‘s analyze them.
United States Still Leads Supersonic Innovation
America pioneered sonic flight milestones setting records for absolute speed as well as productive applications.
The legendary SR-71 Blackbird jet hit astounding speeds of Mach 3.3 – that‘s over 2,200 mph! Designed in the 1960s, nearly three decades later it remains the fastest manned air-breathing aircraft ever operated.
On the commercial side, the anticipated domestic supersonic airliner named Boeing 2707 promising coast-to-coast flights in 2 hours could have preceded Concorde‘s glory. But the program was cancelled in 1971 before production began due to concerns with sonic booms.
Today NASA continues high-speed research with futuristic models like the X-43A demonstrating scramjet Mach 9.6 velocities. By opening access to its wind tunnels and supercomputers, NASA also enables private players. We discuss them next.
