The official opening of the 15th China Air Show was officially opened.In this air show, the Peoples Air Force, the Navy, and the Army all sent the main aircraft models to participate in the exhibition.In the adaptive training from November 8th to 10th, multi -type domestic fighters such as F -35A, J -20, transport 20, oil transport 20, Zhi 20, J -15, straight, and straight 8 appeared in turn, showing the new era New achievements in the development of Chinas aviation industry.
Behind the achievement is a powerful team that strives for aviation scientific and technological innovation.For more than half a century, the strength of China Aviation Industry Group has supported model strength verification and identification as a mission. The system has established a technical level international advanced and large capacity of aircraft strength test conditions, which has effectively guaranteed the research and development of each model. With verification intensity test requirements, scientifically constructed the "building block" verification system from component level, component level, component level to the full -level four -level "building block" verification system, and successively formed the nine major aircraft test capabilities, which effectively guaranteed each. The models of the model first fly, smoothly shape, improve and optimize, safe operation and other development needs.
So, what are the test capabilities of the nine major aircraft in the aircraft strength?What problems can be solved?Come, a set of brilliant badges to help you understand deeply.
PS: Gifts at the end of the text, please pay attention to the message "Check"!
01 All -machine static test
Want to do the extreme action?Lets talk about it first!Want to try if my bones are strong?
This is a series of complexity such as air power, engine thrust, ground landing frame reaction force that simulate aircraft flights in the ground state The load conditions are truly applied to the body structure to measure whether the real aircraft structure is qualified during the entire flight.
02 All -machine fatigue test
One rigorous long -distance running, let me know where it is easy to muscle strain .
This is a variety of air and ground use that simulate aircraft in the entire service period throughout the service period. And by testing the scratching and expansion of the structure of the aircraft structure, determining the weak part of fatigue is a key test for verifying the design of the aircraft structure and the manufacturing process. It provides test data support for the formulation of aircraft maintenance manuals and out -of -field maintenance schemes. It is to ensure the safety of aircraft safety. Key test of operation.
03 03 All -machine ground vibration test
I can test my dance and rhythm, let me go to Zhen Zhen Not chaotic.
This is the free suspension of the aircraft in the ground simulation of the aircraft, and use the excitement system to apply incentives to measure the power of the aircraft structure ( The inherent frequency, vibration and structural damping, etc.), support the analysis of the modification and tremor characteristics of the aircraft structural dynamic model, is a key test subject that must be performed before the aircrafts first flight and continuous test flight stage.
04 Test of the Falling Seismic Test
Ban Moon Board.
This is a land impact load that the aircraft structure received by the ground test during the landing process through ground testing The impact response and multiple landing life, obtain the functional reliability of the entire aircrafts impact on the load environment, evaluate the systems functional reliability of the airborne equipment, fuel tank, and wing structure. Analysis provides test data.
05 Test of the whole machine falling test
I want to ensure that passengers in belly are quite safe!
This is the destruction mode, structural response, passenger loading and energy absorption characteristics under the condition of verifying the emergency collision of the aircraft structure, the structure of the aircraft structure, the structure of the aircraft structure Comprehensive integration verification of key design indicators such as collision resistance, cabin safety, occupant protection, emergency disconnection, etc., is the key technology of the civil aircraft strength verification system.
06 All machine pneumatic elastic test
I adapt to the feeling of "dancing" in the air in advance.
This is the non-frequent momentum that the aircraft still suffers through the exciting equipment to simulate the aircraft in actual flight, so as to achieve tremor on the ground, etc. The pneumatic elastic characteristics test is an important basis for the aircraft tremor flight test, which can be supplemented with the wind tunnel test.
07 The entire machine climate test
There is a house that can call the wind and rain ", which tested me in it inspect The ability to adapt to various extreme weather.
This is an important means to adapting to climate environmental adaptation and evaluation of weapons and equipment, ground supporting facilities, personnel maintenance protection, etc. The design and process defects such as verification model equipment and ground guarantee facilities support the development and optimization design of equipment.
08 All -machine thermal strength test
Boving my face.
This is a ground test for high-speed or hypersonic capacity aircraft.In the experiment, not only the pneumatic power be afforded by the structure of the aircraft, but also the harsh air heating effect produced by the body structure and the severe friction of the air. ) "A variety of means to achieve structural temperature response.
09 09 Full machine load calibration test
At any time through my "body reaction " Load!
This is the equation of strain-load (curved moment, shear, torque) equation through the static test method on the ground and The verification application is performed in the development of the model to determine the calculation method for the test load of the key parts of the aircraft. After the aircraft is shocked in the test, it cannot directly obtain the measurement difficulties of the bending moment, torque and shear power of the assessment structure.
Under the escort of the above intensity test, a variety of outstanding fighters can be safe and efficient at the air show and actual tasks, presenting all -round outstanding performance.
The air show is as soon as the air show, giving gifts is our excellent "tradition".
At the end of the message at the end of the article at the end of the airline WeChat "A set of badges (send!) to understand the nine" Martial Arts Rejuvenation "behind the fighter" Strong Body ", tell us that you think the most Interesting, most unexpected, and most impressive aircraft strength tests, and explained the reason.
We will draw 20 messages readers and send out a aircraft strength test commemorative badge (as shown above).There are 20 per person per person.
Activity time: From now until November 17th at 18 pm.
Gifts are provided: China Aviation Industry Group strength.
Note: The badge is one person (not a set).
During this years China Air Show, watching aviation will also launch rich activities. There are a lot of gifts. Welcome babies to squat and pay attention!
