The database engine was written by Thomas Mueller. He also developed the Java database engine Hypersonic SQL. [2] In 2001, the Hypersonic SQL project was stopped, and the HSQLDB Group was formed to continue work on the Hypersonic SQL code. The name H2 stands for Hypersonic 2, however H2 does not share code with Hypersonic SQL or HSQLDB.
The first manufactured object to achieve hypersonic flight was the two-stage Bumper rocket, consisting of a WAC Corporal second stage set on top of a V-2 first stage. In February 1949, at White Sands, the rocket reached a speed of 8,290 km/h (5,150 mph), or about Mach 6.7. [1]
Oreshnik (Russian: Орешник, lit. 'Hazel tree'), [2] is a Russian intermediate-range ballistic missile (IRBM) characterized by its reported speed exceeding Mach 10 (12,300 km/h; 7,610 mph; 3.40 km/s), according to the Ukrainian military.
The Boeing X-51 Waverider is an unmanned research scramjet experimental aircraft for hypersonic flight at Mach 5 (3,300 mph; 5,300 km/h) and an altitude of 70,000 feet (21,000 m). The aircraft was designated X-51 in 2005. It completed its first powered hypersonic flight on 26 May 2010.
A Chinese aerospace firm has completed the first test flight of a passenger plane that it claims can fly at Mach 4 – more than twice the speed of Concorde.. Beijing-based Space Transportation ...
Unlike larger hypersonic cruise missiles, the Mako offers a degree of standoff range and rapid response capabilities, making it suitable for a variety of military operations that require a shorter range than the Hypersonic Air Launched Offensive Anti-Surface (HALO) missile — which is optimized for anti-ship missions – or the much larger AGM ...
