Because the wave drag plays a dominant role, the drag coefficient for a sphere flying at
hypersonic speed is close to that of a sphere cylinder, which is 0.87 to 0.90 experimentally [32] and 0.87 to 0.89 in numerical results.
A simply supported square plate fluttering at
hypersonic speeds is studied considering both the airflow and structural nonlinearities.
There are two methods of reaching
hypersonic speeds and Putin said during his annual televised call-in show June 8 that Russia had mastered them both.
The China Aerospace Science and Technology Corporation (CATSC) is behind the project of a plane/spacecraft hybrid that will travel back and forth between the runway and space orbit at
hypersonic speeds, Popular Science reported.
Hypersonic speeds are high supersonic, usually referring to Mach five and above, which can usually only be generated using advanced propulsion technology such as ramjet or scramjet engines.
Washington, July 25 ( ANI ): A large inflatable heat shield developed by NASA's Space Technology Program has successfully completed a trip through Earth's atmosphere while travelling at
hypersonic speeds up to 7,600 mph.
Russia's latest military weapon could be a stealth bomber capable of flying at
hypersonic speeds and dropping nuclear bombs from space.
Hypersonic speed is the science behind the technology of this weapon.
Having entered the Earth's atmosphere at a
hypersonic speed of at least 33,000 mph the meteorite shattered about 18-32 miles above the ground, the Russian Academy of Sciences said in a statement.
The Russian Academy of Sciences estimated that the space rock weighed about 10 tonnes and entered Earth's atmosphere at a
hypersonic speed of at least 54,000km/h (33,000mph) before exploding 30-50km (18-32 miles) above ground.
After it is released, the "scramjet" engine will ignite, rocketing the Waverider to
hypersonic speed to heights of 70,000 feet.
The South China Morning Post reported quoting the anonymous source that the under-development DF-17 missile is capable of achieving
hypersonic speeds and shifting targets in flight.
