    <p> no one answered. This series of articles / Beijing News reporter Wildland (Original title: Count recent "Sleepy News") (EdiHypersonic aircraft is the third revolution of the aircraftSina military Editor: In order to better render military diverse content for readers to meet the reading needs of different readers, to discuss domestic and international strategic developments, military Sina exclusive launch of "deep military" section, the depth of interpretation of military news hidden behind the trend, three-dimensional rendering China complex environment faced by military strategy, welcomed the attention. Recently,nike air force, the emergence of online news hypersonic aircraft test flight, which indicates that the development of domestic hypersonic aircraft entered a new stage. Generally hypersonic aircraft flying faster than referring to the Mach 5 aircraft,nike tn, it is the second propeller, jet aircraft of the third revolution,tn requin pas cher, but also countries in the new century,louboutin pas cher, competition for high ground. Previously many people may have seen the Chinese news hypersonic aircraft, then the hypersonic aircraft What is the difference, the news of the protagonist is China's aviation industry instead of the previous aerospace industry, it can be speculated that the test flight of the aircraft should be air-breathing hypersonic aircraft, which means that it should be based on joint power turbine propulsion system (TBCC), rather than on joint rocket propulsion systems (RBCC). Lockheed - Martin SR-72 hypersonic reconnaissance aircraft conceived latest figure exposureAfter conventional turbojet / turbofan engine flight speed of Mach 2 or less confined to the range.</p>

    <p> reaching the upper limit of this range, the rotational speed of the turbine blades reach the top, relatively large heat and cause erosion problems, and thereafter can only rely on speed ramjet ,outlet peuterey, it is relying on to boost air flow, no turbo, so the speed range is relatively large, generally sub-combustion ramjet engine to meet the aircraft speed is Mach 6-7,soldes louboutin, while the scramjet engine is not decelerating airflow directly into the combustion chamber, it can reach Mach 10. However, this principle ramjet it must have a start-up speed, so it is necessary to form a coalition with other power plant propulsion system, the most common is the solid rocket ramjet plus, which is currently the most common equipped with supersonic anti-ship missiles,scarpe hogan, but the solid rocket engine single use only, not suitable for re-use vehicle power system,hogan rebel, so there are a turbo-stamping joint propulsion system, there was news that the country is being developed jointly stamping turbine propulsion system. It profits from ordinary aircraft turbine engines allow the runway to take off after the high altitude reached ramjet start speed, then use the ramjet, the aircraft continued to accelerate to a predetermined speed.

    <p> repeated use,2014 Scarpe Hogan, versatile, high durability, safety, and can use ordinary fuel,nike air max outlet, the economy is good,nike free run 3.0, environmental pollution, low technical risk and so on. Can be used as a reusable space vehicle to orbit departure day / return of the low-speed range propulsion power, but also as various types of hypersonic vehicles, especially in remote,air max pas cher femme, manned hypersonic aircraft takeoff acceleration and low speed propulsion power, but also alone as supersonic and hypersonic military and civilian aircraft power, it is a focus of recent national development. From now scramjet although excellent performance allows the aircraft to achieve Mach 10 hypersonic flying around, but it's also very big difficulties,barbour paris, especially combustion start and maintain a very hard, the Americans say is equivalent to the hurricane Among lit a match and let it stable combustion.</p>

    <p> so the Americans did not let the scramjet to achieve work goals 300 seconds,chaussure louboutin, this ultra high-speed flight for the thermal protection requirements of the aircraft is also very high,nike air max command, the corresponding need more advanced structures and materials,giuseppe zanotti pas cher, in addition to other aerodynamic design, guidance and navigation problem, so scramjet though is the direction, but were unable to enter the utility. So now the focus of all countries is a turbine sub-combustion ramjet, and strive to reach the speed of Mach 5,louboutin femme, which is the threshold into hypersonic flight, which is the scramjet engine starting speed, so that reduces the requirements for the engine itself, while For aircraft require a corresponding reduction in, so I guess this country flight of hypersonic UAV is the adoption of a turbine should be sub-combustion ramjet engine, which is to verify the preliminary results achieved in the domestic TBCC research projects,nike roshe run, and small thrust TBCC engine engineering verification, for the future development of high-thrust engine and in the future experience TBCC Yachao turbine combustion ramjet, basis.
