However, Yang Hui is now becoming more and more curious, why the UAV project department would think of taking over this kind of manned low-end ground attack aircraft, which is also quite curious. Pen, fun, pavilion www. biquge。 info and soon there was a reasonable explanation, Yang Yue's follow-up explanation clearly showed the concept of the drone project.

"Soon after the exchange in Hongdu, we got the news that Sri Lanka's Jianjiao 7A was shot down by the LTTE when it was carrying out a ground attack mission, and the news from Sri Lanka at that time said that it was one of their seed instructors who flew the plane, which can be described as a heavy loss. From that moment on, our UAV project department had a preliminary idea, in order to avoid the loss of valuable pilots in the task of suppressing bandits, so that the UAV has basic ground capability is our goal. ”

This statement is quite interesting, of course, it is also very practical, before Sri Lanka a Jianjiao 7A was shot down by the LTTE with a high plane when carrying out a ground attack mission, at that time it also caused a lot of sensation in the southwest of AVIC and even in the world, after all, the plane was shot down in the operation to suppress bandits, and it is not good to hear.

Even if you are the kind of Iraq that had to be sacrificed for the grand strategy, but in the end relied on the record of sinking an aircraft carrier, the reputation of the Jianjiao-7A and Jian-74 series aircraft at that time was not affected in any way. The downing by government forces was indeed well ridiculed by fighter manufacturers in various countries.

I didn't expect this UAV project department to really fight for the company, there just found that Jianjiao 7A is not suitable for dangerous ground attack missions, this UAV project department will prescribe the right medicine to prepare a whole UAV, this Nima is the efficiency that a super military company should have!

"I think this project is very good, or very feasible, to replace the turbo trainer with drones these cross-domain guys, so that the trainer can return to their own work, and once the toucan's proud multi-purpose capabilities are broken, it will be difficult to compare with the L-8, a specially optimized jet trainer."

The starting point of the UAV project team is to develop a drone that can meet the needs of the government army. The government forces need to fight the drones, but then again, fight against . What is the difference between armed government and fighting terrorists? In fact, it is almost difficult for these two to fight back in the face of blows from the middle level of the sky.

After clarifying the early research and investigation conclusions of the UAV project team, Yang Hui can conclude that based on this design requirement, the UAV that is finally taken out can definitely meet the needs of the future battlefield, so Yang Hui can also ask all parties in the company to coordinate and cooperate with the UAV project team to carry out research on various subsystems.

"The operational objectives of the design are clear, and for such low-level ground targets, the use of drones is almost sufficient. But does your project department have a preliminary design plan now? Or the technical architecture of the aircraft, if you want to achieve the integration of inspection and combat, this is a big step forward in technology from the artillery reconnaissance UAV we developed with a vehicle-mounted rocket boost. ”

Although the design of the "Artillery Reconnaissance-1" UAV has only been finalized for five years, it does look like an ugly duckling at this time, not that the aerodynamic design is not good enough, but that the civilian-grade plastic used in the manufacture of the aircraft is too pitted, and that thing is too simple in all aspects now. In the end, the service life of the aircraft body is too low, and from the delivery of the aircraft, until now, the southwest side of AVIC has carried out the second replacement of the fuselage shell of those aircraft.

Based on the above design and use experience, civilian-grade engineering plastics must not be used, and the fuselage made of composite materials + aluminum-lithium alloy is the king, and fortunately, at this time, AVIC Southwest has caught up with the world's forefront of the third-generation alloy in terms of aluminum-lithium alloy, and has also mastered the use of composite materials, so the new Chada integrated UAV can be manufactured with enough excellent materials.

For the follow-up UAV project department, how to design a new UAV, especially the aerodynamic design, this aspect is worth paying attention to, does Yang Hui need to open a golden finger to draw the aerodynamic shape design? So is the aerodynamic of Rainbow 3 better, or is the aerodynamic design of pterosaur and predator better?

It's a pity that when Yang Hui was thinking about how to choose the aerodynamic design of the UAV, the UAV project department had already taken all aspects into account early, and even the aerodynamic design had been roughly determined.

As the chief engineer of UAV design, Yang Yue knows best: "Don't worry, although we haven't come up with the design plan yet, we also have a preliminary aerodynamic architecture, mainly on the basis of "Gun Detective-1" to enlarge and improve: increase the diameter of the fuselage, cancel the design of the rocket booster, increase the front three-point retractable landing gear, the previous design of the upper wing in order to ensure the safety of the vehicle-mounted rocket booster design, and now it has been changed to a lower wing that is more suitable for UAV use. A bubble nose was added to install the on-board equipment. ”

As soon as he saw this design scheme, Yang Hui understood that this design scheme should be enough to meet the requirements of use, after all, when designing the "Artillery Reconnaissance-1", Yang Hui came up with a pneumatic design scheme that was the pneumatic of the Hermes 450.

That is to say, it is now equivalent to the aerodynamic amplification and optimization of the design of Hermes 450, and according to the new aerodynamic design scheme described by Yang Yue, it is obvious that the aerodynamics of Hermes 450 have been upgraded to Hermes 900!

If the aerodynamics designed this time reached the Hermes 900 level, then Yang Hui can be regarded as able to recognize, and it just so happens that the technology accumulated by AVIC Southwest is enough to design the Hermes 900 This level of big guys, thinking that the rotary engine designed for the "Gun Reconnaissance-1" at that time has long been developed and matured, and the improved version after the increase in power has also been finalized, which can be installed on the new Chada integrated UAV.

Other airborne infrared navigation, laser guidance systems and other necessary optoelectronic equipment on UAVs, these have carried out a lot of technical research in the J-18 project, and can be put into use with a little improvement, so in this case, even if the MQ-1 level of the UAV can not be manufactured, but the RQ-1 level of long-endurance reconnaissance UAV for AVIC Southwest does not have any technical difficulties.

However, now that Yang Hui knows these situations, it is time to add a new design requirement: "Of course, this aerodynamic design is not bad, and I can roughly think of what your design plan looks like, but I need to put forward a new requirement now: long endurance!" ”

If the UAV can not have a long endurance ability, it is definitely not enough, which is very embarrassing in the UAV of the previous face of the republic, due to the problem of the engine, it often leads to the same level of UAV, and even the aerodynamic design is almost the same, but the Republic of China is usually only about half of the range of others.

Now AVIC Southwest is engaged in the development of small engines because of Shuguang Company, whether it is a piston engine or a rotary engine, it is world-class, but based on Yang Hui's deep obsession in a face, this time the range or duration of the aircraft must be soared to be stronger than the Predator.
