Chapter 1153 Completion of Aerodynamics Research Laboratory

The next sub-system research work is in this aerodynamic shape, to put it bluntly, it is the aerodynamic adaptability design of the aircraft body.The so-called aerodynamic shape refers to the shape suitable for moving in the medium to reduce the movement resistance of the object moving in the gas medium.The aerodynamic shape of an aircraft will determine its aerodynamic characteristics in the state of gas flow, and these aerodynamic characteristics are closely related to the optimal solution of orbit change.This takes into account constraints such as thermal loads, peak overloads, and flight maneuverability, and thus constitutes a shape-body optimization problem.

The aerodynamic shape is closely related to the aircraft shape structure and the layout of large parts and the dynamic characteristics of the aircraft and the aerodynamic force it receives.It is related to the flight characteristics and performance of the aircraft, so the overall external shape and position arrangement of the aircraft are called aerodynamic shape.To put it simply, the aerodynamic shape refers to the design and shape of various parts of the aircraft's fuselage, such as the fuselage, main wing, and empennage.The aerodynamic shape mainly determines the maneuverability of the aircraft. As for where the engine, cockpit, and weapons are placed, it can be generally classified into the overall shape of the aircraft.Because whether it is the cockpit, or the weapon system, or the air intake of the engine, or the tail nozzle, it all involves the technology of aerodynamic shape.

Moreover, the aerodynamic shape is an important aspect that determines the maneuverability of the aircraft. The design tasks of the aircraft are different, and the maneuverability requirements are also different, which will inevitably lead to different design schemes of the aerodynamic shape.There are many kinds of aerodynamic shapes of modern combat aircraft, mainly including conventional shape layout, canard shape layout, tailless shape layout, three-wing shape layout and flying wing shape layout.These shape design layout schemes have their own particularity and advantages and disadvantages.Designers and users can design related aerodynamic shapes according to their own needs.

Of course, what Jiang Chen and the others are going to build is a civilian light fixed-wing airliner, and the requirements in terms of aerodynamic shape are not that complicated.But even if it is a conventional shape layout design, it also involves various problems, so it is not a simple calculation and design.Among them, many related technologies and calculation methods must be transported, as well as some hardware measures.The two most important aspects, on the one hand, are the wind tunnel, or more formally, the aerodynamics research laboratory.It is a research aircraft, of course, it is not limited to aircraft, such as automobiles, motorcycles, and paragliders, which require related aerodynamic research work in wind tunnels.

The current aerodynamic research laboratory has basically been completed, and a medium-sized wind tunnel from low speed to subsonic speed has also been completed.In order to build this medium-sized variable speed wind tunnel, Jiang Chen and the others spent a lot of resources.This includes a lot of money, as well as other resources, such as raw materials and manpower.Moreover, there are some things that cannot be bought with money at all. For this, Jiang Chen has thought of many ways.And just this wind tunnel plus the attached laboratory facilities, the entire laboratory cost a total of [-] to [-] million yuan. It is unbelievable to spend so much money to build a laboratory in this era. It cost tens of billions.

For this wind tunnel, or the aerodynamics research laboratory, Jiang Chen has great hopes.Of course, this money was wasted. During the trial operation of the laboratory, Jiang Chen and the others had brought many surprises here.For example, in the research and development of new models, because there is help from the laboratory.Therefore, many optimizations have been made in the shape design of the car, and the time has also been shortened a lot.The body design of the new model is not only more in line with aerodynamic design, but also more aesthetic and modern technology.More importantly, after the optimized design, the overall performance of the new model has been improved a lot.Especially in terms of acceleration and top speed, it has been greatly improved.And because the air resistance is reduced, the energy consumption of the car is also reduced, which makes the car more fuel-efficient and environmentally friendly.

For another example, the design of motorcycle road sports cars in the company has also applied a lot of aerodynamic design technology, which has greatly improved the overall performance.Related to it is the design and development of paramotor and parafoil, which has also achieved very gratifying success.It is different from the research direction of automobiles to comply with aerodynamics and reduce drag.The research direction of parafoil and powered parafoil is how to increase the resistance of the air to make the speed of the parafoil slower and smoother and improve the efficiency of the parafoil.Although it is just a small parachute, the technology contained in it is very complicated. There are very limited countries in the world that can produce qualified and advanced parachutes, especially parafoils.

Of course, relying on this laboratory, great progress has been made in the project of the technical research and development laboratory of B17 factory.The biggest progress should be the research work on the aerodynamic shape of the missile body.After using aerodynamic related technologies, the overall performance of the missile has been improved a lot.Not only faster, but also faster, higher, and more stable, greatly speeding up the research and development of new models of the 'Chasing Wind' and 'Broking Shadow' series missiles.In this regard, there is still research on the ammunition of individual weapons.For example, in terms of warheads, different materials, different structures, and different shapes of warheads have different flying attitudes in the air.In the past, the research on this aspect was very scarce, but now with this wind tunnel, the research work on this aspect has also begun.Of course, there are still many application projects undertaken by this laboratory, many of which are from other research units.Regarding this, Jiang Chen also agreed conditionally.On the one hand, this is conducive to the progress of domestic aerodynamic research technology, and on the other hand, it is also the normal and healthy operation of this laboratory in the future.

The research and development of the aerodynamic shape of this light fixed-wing aircraft also relies on this laboratory.After hundreds of hours of experiments, the R&D team finally came up with an ideal and mature solution based on the obtained data.So far, the start-up shape work of the aircraft has finally come to an end, and then began to transfer to more detailed airframe design and development work.

Of course, in addition to this aerodynamic research laboratory, there is another aspect that is also very important, and that is the computer center that has been put into use.Whether it is the avionics system, the telex system, or the research work on the aerodynamic shape, it involves a lot of data calculation work.In the past, these tasks were only carried out by manpower or simple calculators, which was very inefficient and the data obtained were often not accurate enough.This situation has changed dramatically since it was applied to the large supercomputer in the computer center.In the past, the data calculations of many people for more than one month or even several months were put in the computer center, and it only took more than one hour or several hours to complete the calculation.Moreover, the result was checked and calculated many times, which was very fast and accurate.Therefore, since it was put into use here, it has attracted a large number of application computing projects.And this week, based on the principle of getting the moon first, Jiang Chen and his company's many scientific research projects have obtained huge benefits and achieved great results.
