In the JF-17BLOCK2 the message, the outside world for the first time to know the SD-10B active radar guided air to air missiles, the existence of Pakistan that the SD-10B's performance can be introduced with AIM-120 air to air missiles, compared, and in weight than the existing The SD-10 to lighter, from the air show public view, China's SD-10 air to air missile a maximum range of over 70 km, the effective range of 50 km, and AIM-120A is similar to the latter's maximum range of more than 80 km, the effective range of 55 km, but the SD-10's size and weight must be greater than AIM-120A, so that for the JF-17 light fighter, the mount SD-10, on the flight performance impact is too large, in particular, mounted on the outer wing pylons, you need to reach launchers to adjust the focus of the new century from the U.S. introduction of F-16C/D-BLOCK52 PAF fighter, equipped with the above AIM-120C5, the 1990 Taking into account the U.S. Navy's AIM-54 "Phoenix" the long-range air to air missiles, retired, the successor of advanced air to air missile-AAAM plan is terminated, the U.S. Navy for long-range air strike capability targets a substantial decline, as a quick supplement to the U.S. Navy requires AIM-120 can intercept distance of more than 40 miles (60 kilometers) of air targets, this is the AIM-120C5, compared with the prototype missile, the missile to increase the weight of the missile engines, increased from 45 kg to 50 kg, while improving the grain's surface, so that more regular and full combustion, increasing the time and fuel specific impulse, so that AIM-120C5 missile interceptor prototype increases range from about 10%, while improving the guidance Head of the signal / data processing capacity, increasing the number of warhead fragments, and comprehensively improve the three generations of the twin's ability to destroy aircraft, the improved AIM-120C5 and AIM-120C7 continue to increase the rocket engine, its effective range has been further increase from Pakistan's point of view of information sources the performance of SD-10B may be in line towards the AIM-120C5, in improving the range, based on the reduced size and weight, to improve the adaptability of loading, I think it is very important is the possibility of SD-10B also taking into account China's stealth fighter being developed for weaponry, stealth fighter jets to reduce the RCS, airborne weapons are generally placed above the bomb bay, in order to narrow as much as possible inside the bomb bay mounted weapons , so it is necessary to reduce the air to air missile system, AIM-120C than the AIM-120A on the reduction of the tip, to improve the F-22's bomb bay to mount the number, SD-10B may also be the idea, with a range of improved, guided accuracy of the system have to keep up, SD-10B is said with a surprisingly active / passive complex guidance system, with the guidance we are familiar with the source of interference in different ways, this active / passive composite guidance is to use passive mode other airborne radar signal receiver, and then start using the former terminal guidance radar target data to improve detection, both work to improve the seeker detection range and interference, be pointed out that SD-10B does not plan to adopt This guidance system of air to air missiles, AIM-120 also have had such a plan, but the technical difficulty of this seeker of the great need to address the broadband active / passive antenna and radome composite guidance, data fusion series of key technologies Therefore the author for the SD-10B is equipped with guidance systems such reservations, but we seem to speculate about our range air to air missiles in the direction of development.
Improve the performance of air to air missiles, airborne fire control radar, a necessary requirement to be followed to improve the performance, because the latter need to provide air to air missiles to attack the target zone data to calculate, JF-17BLOCK2 with SD-10B-air missiles, which means that the China should be equipped with airborne radar, this is because an aircraft using a weapon, you will need the associated computer program resides in the task or the fire control computer, and these procedures are based on the missile launch envelope preparation , while the missile launch envelope is the core countries of airborne weapons secrets, related to the work of the missile terminal guidance radar tracking distance and angle and the maximum tracking speed, time, energy work on the bomb, the engine thrust and working hours, definitely not will be exposed, so the JF-17BLOCK2 task is basically a computer can be sure that our products, as stated earlier airborne radar to detect the target, it will smooth the data and make forecasts, then the data to the mission computer for processing by the post manipulation of instructions to complete the aircraft, missile attack area, the calculation of the radar scan parameters, clearly would involve airborne radar-related parameters, which is also confidential, so I thus believe that the JF-17BLOCK2 still use our avionics system . 实际上JF-17BLOL01的航空电子系统相当先进,已经超过现有的第三代作战飞机,第三代作战飞机配备的联合式航空电子系统,就是利用数据总线各系统相联, 系统核心是任务计算机,任务计算机负责处理各探测系统获得的信息,然后交显控计算机进行统一显示,而JF-17的航电系统以武器管理控制计算机为核心,其最大特点就是综合了任务和显控两个计算机的功能,从而降低了系统的复杂程度,简化了结构,降低了重量,提高航电系统整体的可靠性.同时也为未来的升级打下了坚实的基础. In fact JF-17BLOL01 avionics system is quite advanced, more than the existing third-generation combat aircraft, the third generation of combat aircraft is equipped with joint-type avionics systems is the use of the system data bus linked to the core mission computer systems, the task computer responsible for processing the detection system to obtain information, and then submitted to a unified display and control a computer display, and the JF-17 avionics system for the management of weapons control computer as the core, its greatest feature is the combination of two computer tasks and display control functions , thereby reducing system complexity and simplify the structure, reducing weight, improving the overall avionics system reliability but also for future upgrades to lay a solid foundation.
According to the China Import and Export Corporation to provide information, present with the JF-17BLOCK1 airborne China KLJ-7 radar-based fire control radar, the radar antenna diameter of 600 mm or so, the next, as detection range of 80 km, the apparent 105 km or so.
