China or directly into the era of unmanned aircraft carrier
the “Varyag” aircraft conversion process, we have experienced various difficulties. China wanted to ensure that imports from Russia and arresting cable aircraft carrier landing, only to Russia but the pressure may come from the United States refused to sell, and later from Sweden’s successful procurement of the arresting cable, and use of Western technology to develop domestic electromagnetic catapult used to replace the steam catapult. If this news is reliable, domestic electromagnetic catapults will be a qualitative leap for the Chinese aircraft carrier, because the electromagnetic catapult is a necessary condition of the UAV board the aircraft carrier, the United States for the next generation of aircraft carriers to install the electromagnetic catapult. With the advent of the electromagnetic catapult, China will enter the era of unmanned aircraft carrier.
carrier towards the era of “electromagnetic catapult
According to the Guangming Wang quoted reports in the past 40 years, the U.S. aircraft carrier has been in use steam-powered catapults on carrier-based aircraft catapult boost. Installed the latest on the aircraft carrier “Nimitz” class steam-powered catapult that can catapult an aircraft every 60 seconds. “Nimitz” class carriers with four catapults, as a whole, average every 20 seconds an ejection aircraft.
from the U.S. Navy’s use of, now used in steam-powered catapult is very reliable. During use, the effectiveness of each catapult an average of 74%. In wartime, for four catapults the possibility of at least one normal work up to 99.5%. Steam-powered catapult is also proved to be very safe: the recent 10-year period, the records of more than 800,000 aircraft ejection, only just 30 turnovers. 30 turnovers, only one result in an aircraft losses.
steam catapult is very reliable and safe, but it is still deficient. The steam catapult, the ejection of aircraft maximum weight must not exceed 70,000 pounds. Ejection when the aircraft has a maximum weight limit, the steam-powered catapult ejection in the low energy levels are also insufficient. Therefore, the aircraft lighter but harder to ejection. In fact, the steam-powered catapult catapult the current U.S. military to use unmanned aerial vehicles. In the ejection process, the catapult to the thrust of the aircraft often change, a very large pressure to the body, for someone aircraft, these pressures will diminish. For unmanned aerial vehicles, will need a stronger body institutions.
for the increasingly widespread use of unmanned aerial vehicles, can not be used on the aircraft carrier is a very serious flaw. As information technology continues to make a breakthrough, the development of lighter, smarter weapons is considered more of a threat force means of warfare, will be widely adopted.
is the electromagnetic catapults will largely compensate for the defects of the steam-powered catapult. This technology will make catapult produce electromagnetic waves, electromagnetic waves will move the length of the catapult. Reciprocating track of the aircraft catapult attached to an armature, the armature control electromagnetic catapult the necessary power and speed. This technology often used in modern facilities with the current somewhat similar, especially in the urban transport system.
electromagnetic catapult device and steam catapult compared to more variable power operation. Its ejection than steam catapult more energy efficient. Through better control of the acceleration in the ejection process, ignoring the level of energy released, in theory, the aircraft carrier the future can catapult a heavier or lighter aircraft. Therefore, the UAV aircraft carrier aircraft carrier will also become possible.
taking into account the smaller UAV Dimensions and weight, “Varyag” aircraft capable of carrying more than 60 unmanned aerial vehicles, with the ability to perform combat missions at any time.
