| Somehow, he managed to come out of the spin and slow his speed to from hypersonic to subsonic. |
|
| Astronauts and cosmonauts have all reached hypersonic speeds while passing through the atmosphere on their way to or from orbit. |

|
| The M45 propulsion system has three-stage solid fuel rocket motors producing hypersonic speed. |
|
| Military analysts said the claimed new weapon could be a hypersonic cruise missile or manoeuvrable warheads. |
|
| At such hypersonic speeds, planes could fly around the world in a matter of hours. |
|
| The two main contenders are hypersonic ramjets or scramjets and nanotube-based space elevators. |
|
| A single shooter employing this hypersonic weapon can cover 49 times the area reachable with a conventional cruise weapon. |
|
| When a particle slams into it at hypersonic speeds, the particle bores its way in and gradually comes to a stop, intact. |
|
| The rifle fires steel spikes at near hypersonic speeds, using a magnetic system to power it. |
|
| The angle value of the wings is selected to have an angle of attack of 45°-65° in hypersonic flight. |
|
| Behind a hypersonic shock wave the temperature at the leading edge of a hypersonic craft scales inversely with the square root of its radius of curvature. |
|
| Mr Khosla has invested in companies that promise ultra-efficient air conditioning using hypersonic vortices or desiccant chemicals. |
|
| Current projects include numerical evaluations of several hypersonic missile configurations. |
|
| Others projects were to use the VM-T as a launch platform for an hypersonic drone or as an engine testbed. |
|
| A hypersonic weapon operator may be a thousand miles from the weapon he or she launches, and thousands more from the target. |
|
| A hypersonic weapon launched from New York could reach Moscow in less than 40 minutes. |
|
| Going at hypersonic speed, everything that David passed was a giant blur. |
|
| Their record on clocking school buses at hypersonic speeds is not noted. |
|
|
|
| They were made with a material that could stand hypersonic speeds. |
|
| He suddenly felt like he was rocketing skyward at hypersonic speed. |
|
| Aerion does not yet have a manufacturing partner, however. America's armed forces see potential in hypersonic aircraft, which fly at Mach 5 or faster using a type of engine known as a scramjet. |
|
| He reckons that scramjets might one day power civilian aircraft. Some military types have enthused that, before then, hypersonic troop carriers could be built. |
|
| Within 50 years, he continued, we would see hypersonic travel, with planes flying at 100,000 feet and commuters travelling from London to Sydney and back within a day. |
|
| But the main challenge that Lapcat's 14 partners are trying to meet is the radical revolution in engine design which is needed to make commercial hypersonic flight feasible. |
|
| Garrincha, hogging the right touchline, deceived his marker with an hypersonic, trademark body swerve, before earning a corner, which he looped into the vicinity of Vava. |
|
| Similarly, Russia's deputy prime minister, Dmitry Rogozin, remarked last year that the design of hypersonic missiles had become a priority for the country. |
|
| The airplane entered a hypersonic spin, descended in an inverted dive at almost Mach 4 and 65,000 feet and finally broke up and crashed, taking the life of Air Force pilot Michael Adams. |
|
| Indeed, the winged devices possess a higher aerodynamic quality in the hypersonic and subsonic flight which allows to limit loads on the crew during the descent in the atmosphere. |
|
| Unsurprisingly, Russia has started work on hypersonic weapons. |
|
| Boeing's hypersonic, supersonic, subsonic and icing wind tunnels in Seattle and Philadelphia will remain open during the renovations. |
|
| Scramjets show the most promise for hypersonic aircraft, but the rapid rush of air through them makes combustion difficult. |
|
| The final chapter addresses hypersonic flow, assessing the accuracy of numerical simulation through NATO RTO hypersonic research findings. |
|
| On this basis, a conceptual hypersonic airplane powered by double symmetric scramjet is proposed. |
|
| The goal is to examine how new technologies in areas such as cyberspace and hypersonic flight may be accentuating nuclear risks. |
|
| Army on Wednesday to upgrade its Army Tactical Missile System, or ATACMS, to enable it to deal with hypersonic threats. |
|
| There are obvious advantages to ramping up to hypersonic flight, which is generally defined as anything that reaches at least Mach 5, or five times the speed of sound. |
|
| A hybrid jet engine like SABRE needs only reach low hypersonic speeds inside the lower atmosphere before engaging its closed cycle mode, whilst climbing, to build speed. |
|
| The race to field the first hypersonic weapon is officially on. |
|
|
|
| A lot of work still needs to be done before hypersonic scramjets first see action in battle, but the technology shows great promise, officials said. |
|
| A scramjet inlet was to capture the onrushing hypersonic airflow, compress it while slowing it, and channel it to the combustor that burned the fuel. |
|
| A HYPERSONIC passenger jet which could reduce flights to the Far East to under three hours has been in the pipeline for nearly a decade. |
|
| Hypersonic drones, like the drones before them, are the latest innovation in push-button warfare. |
|
| Hypersonic requires the use of jets known as scramjets, which work on a different principle from normal jets, which are used in supersonics. |
