"China's civil aviation airworthiness regulations are working with the FAA, EASA par with international airworthiness standards, which requires us to process industrial manufacturing technology must catch up to the United States, the European equivalent. "In the eyes of the money Chung Yan, China-made large passenger to fly out of the country, to the world, in addition to meet the Chinese Civil Aviation Authority (hereinafter referred to as" CAA ") airworthiness requirements, but also to rely on a high level of industrial modern manufacturing technology, to meet international airworthiness requirements.
who has 10 years in America, Dr. returnees, carries on China-made large aircraft career take off anticipation, three years ago decided to return to the motherland. Since then, the money Chung Yan has served in China Commercial Aircraft Airworthiness Engineering Center deputy director, recently was also named on the flying hospital "flash" party, is leading a team with high level of combat, fighting day and night in the Chinese autonomous China-made large passenger aircraft C919 design international airworthiness certification first line.
respond to the most stringent international airworthiness standards
"We are trying to fill the Chinese to international airworthiness certification research gaps. This is a challenging battle. "Money Chung Yan reporter's interview, said.
Although China's aviation industry has developed a number of aviation design, manufacturing national standard, but the support and development of China's civil aircraft airworthiness certification system of technical standards has not been established, the international airworthiness study also in its infancy, far from to meet the large aircraft project development, production and use.
fact, C919 really want to enter the international market operations, sales, you must obtain international certification authority. Many countries have recognized the U.S. Federal Aviation Administration (FAA) and European Aviation Safety Agency (EASA) validation capabilities. C919 in order to be sold to the United States or the European Union, you must obtain these two agencies. Some experts have said that because there is a strong civil aviation products internationally, coupled with the ability airworthiness certification, there is a gap between China and the West, so China's civil aircraft manufacturing enterprises in the development of new models, there is a strong desire in obtaining CAA approved as soon as possible to obtain FAA or EASA approval. In order to obtain C919 FAA or EASA airworthiness certification, China's civil aircraft industry need to pay more consideration and effort.
Qian Zhong Yan introduced that, at present, FAA case-based, airworthiness standards have been updated to Amendment No. 138, and revised twice a year about the frequency of rolling update. Currently on transport category aircraft, the amendment was carried out for 25 regulations supplement and modification. In addition, FAA type certification basis in terms, but also to follow valid for five years from the date of application for the requirement that the application for the initial year by the date, after five years if a large passenger has not received airworthiness certification, the certification basis of the application should be added a year after the start of the new requirements, in order to ensure continuous period of five years fresh.
as China's first research and development in accordance with international practice, a large civilian passenger, C919 airworthiness working demonstration projects starting in 2008 when the already launched to the airworthiness requirements into design guidelines, and implement at every stage of aircraft development and aspects. December 19, 2010, C919 was formally accepted the CAA application for type certification. According to Qian Zhong Yan introduced, compared to the Airbus A380, Boeing 787 and other models, as the official date of application C919 late, its certification basis of the combination of CAA CCAR 25 部 R4 version and FAA amendment to the level of 130 regulations, for the amendment No. 130 after the relevant provisions of China Commercial Aircraft extra targeted selection, assessment, included in the application, so the need to meet airworthiness standards C919 current situation is the most stringent existing aircraft. "
Qian Zhong Yan told reporters illustrates C919 airworthiness new requirements. Since the United States, "9.11" incident, FAA in order to prevent terrorist incidents from happening again, issued a series of regulations, which amendment No. 127 in the design of security components, it provides transport category aircraft to be designed and installed the "anti-hijacking door ", that cockpit doors to be able to withstand a certain degree of light weapons and explosive attacks, if terrorists wishing to enter the cockpit hijacking, as long as the driver to lock the door against terrorists can not open the door with a weapon. According to media reports, Commercial Aircraft developed this door more than 2 cm thick, composed of 9 layers of metal and composite materials.
Another example is the "minimal risk bomb location" requirement, which designed and developed to consider the system survivability problems, if found a bomb on the plane, you should choose the most appropriate location to place it while guaranteed minimum degrees, affect the safety of aircraft flying.
Therefore, since the A380 and the B787 does not include such provisions in the certification basis, C919 has become the world's first standard is designed in such a transport aircraft, which the Chinese industry demands a higher level.
airworthiness seize breakthrough research model application challenges
According to Qian Zhong Yan introduction, China Commercial Aircraft subsidiary Shanghai Aircraft Design and Research Institute (hereinafter referred to as "the flying hospital") currently in the airworthiness technology research undertaken considerable work.
First airworthiness regulations for research, that the interpretation of the terms dynamically updated continuously and practice. "In fact, the formation of the amendment abroad a lot of research done early, while models are also rich application experience. Therefore, the flying hospital with foreign ongoing cooperation projects in this field, relevant research topics very much. "Qian Zhong Yan said. For example, he said, for example, for fatigue damage tolerance requirements, Amendment No. 132 explicitly requires the aircraft appeared to avoid the situation of widespread fatigue damage, flying hospital is currently on the terms for this study.
The second is the establishment of airworthiness management systems to explore, namely, how to conduct validation task plan, which is also the case in the domestic blank. Qian Zhong Yan introduced, said aviation disciplines multidisciplinary multi-field, complex manufacturing equipment, design and manufacture of large numbers of people involved, and in the plane of validation and verification process, the commercial aircraft are required to demonstrate compliance with the Council, and the Council is required make the corresponding review. Thus, they constitute the entire validation process huge project. To this end, the Civil Aviation Authority to fly and have reached a consensus on security cooperation Protection Plan (PSP) under the framework of the signing of a special certification plan (PSCP), on this basis, and refined into 66 certification plan (CP) , thus forming a top-level design combined with the specific details of the system architecture, the implementation of specific verification process has been clearly stated. It is understood that the C919 contains over three hundred airworthiness certification basis of the terms of the face of such a complex situation, developed a flying hospital on the appropriate systems management methods, theories, tools, platforms, how the performance of each of the terms for compliance labeling and norms, eventually combined with the development program.
Third, in close cooperation with the R & D department to ensure the airworthiness technology research can be applied model development. Airworthiness Engineering Center as airworthiness departments, and R & D departments seamless, push theory to guide practice, practice and promote anti-theoretical application process.
civil aircraft type certification airworthiness certification work is divided into five stages, namely, conceptual design, requirements to determine, planning, program implementation, Post Certificate. According to Qian Zhong Yan revealed, C919 is currently in the third phase, from May 2012 has continued to promote the validation plan. ARJ21-700 is in the end part of the fourth stage, because it contains a large number of test work, the whole five fourth stage is the longest stage of the section, and subject to compliance data generated certificate of conformance, conformance determine three a refinement step.
In addition, the money Chung Yan also specifically mentioned in the airworthiness technology research, ARJ21-700 airworthiness certification experience is being increasingly used in C919.
It is understood that in 2008, ARJ21-700 aircraft to the applicant through the China Civil Aviation Administration Federal Aviation Administration (FAA) proposed application for type certification. After mutual consultation, FAA FAA expressed its willingness to start the ARJ21-700 aircraft on the "shadow review" and accept the Chinese ARJ21-700 filed application for the type certificate.
"shadow review" substantially validation is the Civil Aviation Authority airworthiness certification capabilities, including visits the Civil Aviation Authority airworthiness certification regulations, management and FAA approval is similar to other content, ARJ21-700 is a "shadow review "the carrier. "Shadow review" after the two governments will sign on transport category airplanes to expand bilateral airworthiness agreement (BAA) or Bilateral Aviation Safety Agreement (BASA). These bilateral agreements will be developed by China's large aircraft, how to make provisions for the FAA's airworthiness certification.
If you're lucky, FAA right to ARJ21-700 as the carrier of the "shadow review" fully recognized, the two sides will sign bilateral agreements to expand, FAA future just right to make a relatively simple recognition C919 review, you can for the C919 and other documents issued by type certificate.
forces overseas into the United
was introduced as an overseas expert money to fly Chung Yan admitted that returning because convinced that China has a large airliner good development prospects, and are willing to effect.
Turning research leading role overseas talent, money Zhong Yan said that overseas talent developed into large passenger will bring two advantages, first, the establishment and improvement of the top-level process. Experts working abroad for many years, for foreign civil aircraft development process management more familiar with the experience of foreign countries into China's development of systems integration, innovation with enterprise features international management system. Second, overseas talent in international cooperation and more exchanges with a strong push, and become China and foreign airworthiness certification in respect of a bridge linking.
integration of resources in foreign countries, the money Chung Yan said, adding that commercial flying in selecting suppliers, will assess the vendor's experience in airworthiness, for example, have already participated in other types of evidence, evidence of its products. C919's major systems suppliers are from abroad, which will receive FAA certification C919 help. First, foreign suppliers can increase moderators C919 at the system level for the confidence. Second, foreign suppliers in forensics, standards development and has extensive experience. Such as DO-160 airborne environmental requirements and test procedures, the fact that many vendors are involved in the development of different levels of preparation of this requirement, discussion, so was very familiar with and understand better able to help the Chinese side through the review. In addition, the Commercial Aircraft will further strengthen cooperation with foreign bureau, for example, ARJ21-700 manufacturing inspection, Chinese and foreign Civil Aviation Authority signed an agreement on the Council, the Council commissioned to do manufacturing FAA conformity inspection, this is the bureau of foreign side edge resources.
i don't think so
that's too pessimistic, I think the to choose which company is more important.
