Waverider
A waverider is a hypersonic aircraft design that improves its supersonic lift-to-drag ratio by using the shock waves being generated by its own flight as a lifting surface, a phenomenon known as compression lift. The waverider remains a well-studied design for high-speed aircraft in the Mach 5 and higher hypersonic regime, although no such design has yet entered production. The Boeing X-51A scramjet demonstration aircraft was tested from 2010 to 2013. In its final test flight, it reached a speed of . History Early work The waverider design concept was first developed by Terence Nonweiler of the Queen's University of Belfast, and first described in print in 1951 as a re-entry vehicle. It consisted of a delta-wing platform with a low wing loading to provide considerable surface area to dump the heat of re-entry. At the time, Nonweiler was forced to use a greatly simplified 2D model of airflow around the aircraft, which he realized would not be accurate due to spanwise flow ...

Boeing X-51 Waverider
The Boeing X-51 Waverider is an unmanned research scramjet experimental aircraft for hypersonic flight at and an altitude of . The aircraft was designated X-51 in 2005. It completed its first powered hypersonic flight on 26 May 2010. After two unsuccessful test flights, the X-51 completed a flight of over six minutes and reached speeds of over Mach 5 for 210 seconds on 1 May 2013 for the longest duration powered hypersonic flight. ''Waverider'' refers in general to aircraft that take advantage of compression lift produced by their own shock waves. The X-51 program was a cooperative effort by the United States Air Force, DARPA, NASA, Boeing, and Pratt & Whitney Rocketdyne. The program was managed by the Aerospace Systems Directorate within the U.S. Air Force Research Laboratory (AFRL). Design and development In the 1990s, the Air Force Research Laboratory (AFRL) began the HyTECH program for hypersonic propulsion. Pratt & Whitney received a contract from the AFRL to develop ...

Naval Boat Building Yard (Sri Lanka)
Naval Boat Building Yard (NBBY) is a shipyard of the Sri Lanka Navy situated in Welisara that produce small and specialist watercraft for the Sri Lanka Armed Forces, state institutions and civilians. History The Boatyard was originally founded in 2000 as the Inshore Patrol Craft Construction Project (IPCCP) for the fabrication of small attack boats including swarm boats to combat the terrorist activities in North and East during the Sri Lankan Civil War. Sea Tigers during its battles against the Sri Lankan Navy used swarming tactics with explosive suicide boats mixed in swarms of speed boats which was effective against larger vessels which were rammed by suicide boats while occupied by swarms. However with the Naval Boat Building Yard introducing the Arrow-class the asymmetric tactics of the Sea Tigers were no longer effective. In 2006, Navy confronted LTTE 21 times and in 2007 12 times and by 2008 (up-to-date) only 04 times as the Sea Tigers lost cadres and fighting platfo ...

Liquid Robotics
Liquid Robotics is an American marine robotics corporation that designs, manufactures and sells the Wave Glider, a wave and solar powered unmanned surface vehicle (USV). The Wave Glider harvests energy from ocean waves for propulsion. With this energy source, Wave Gliders can spend many months at a time at sea, collecting and transmitting ocean data. The vehicles host sensor payloads such as: atmospheric and oceanographic sensors applicable to ocean and climate science, seismic sensors for earthquake and tsunami detection, and video cameras and acoustic sensors for security and marine environment protection purposes. Headquartered in Sunnyvale, California, the company was founded in 2007. In December 2016, the company was acquired by The Boeing Company and is a wholly owned subsidiary, part of Boeing’s Defense, Space and Security organization. Wave Glider Architecture The Wave Glider is composed of two parts: the ‘’float’’, roughly the size and shape of a larg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
