They include Boom Supersonic's XB-1 which the company says will be able to travel at twice the speed of sound for a range of 5,180 miles.
This is key for the future of air travel as heat limits how fast aircraft can fly, including Concorde which travelled at two times the speed of sound.
Boeing also is plowing funding into hypersonic aircraft that would travel faster than Mach 5, or more than five times the speed of sound. The company last year revealed development of a passenger prototype capable of cruising at 3,800 mph or more.
The engine will be able to meet noise and emissions rules while flying faster than the speed of sound over water and decelerating to slower speeds over land.
In addition to the highest speed challenge, solutions for contactless locomotion using magnets were also tested; this is the only way to achieve the speed of sound. Team WARR Hyperloop has also taken up this challenge: Its capsule hovered over the required distance of 25 meters.
The speed of sound is 767mph and anything above that is judged to be "supersonic".
One among other primary conditions for particle agglomeration to be achievable in this acoustic model is that the convective speed of sound should be of the same order as the mean flow velocity, which means, in the case of vehicle exhaust systems where the Mach number of the exhaust flow is no larger than 0.3, the sound speed should be much slower than that in normal cases (around 340 m/s at room temperature).
The turbo jets will help it get to the speed of sound and then retract, allowing the rocket motor to power it to more than 100,000 feet in the air.
Tulsa, OK, November 03, 2015 --( Speed of Sound, a quartet from Region 14, Heart of The Blue Ridge, was crowned the title of International Champion Quartet at the Sweet Adelines International Convention and Competition in Las Vegas this past October.
The manufacturer said the jet will be able to fly at Mach 4.5, more than four times the speed of sound.
His free fall lasted about five minutes, during which time he reached a peak speed of 800 miles per hour - faster than the speed of sound! Eustace deployed his parachute at 18,000 feet and floated back to the ground.
