How to control the quality of industrial UAV before airworthiness specifications are issued

] the world changes. Clicking the "back" button is too fast, too much to see. In fact, the fundamental reason is that people should be reliable and what they do should be more reliable. In the UAV industry that pays attention to precipitation and accumulation, especially for industrial UAVs, people who are more reliable should be safe and reliable machines

however, the facts are not so good. When talking about the safety and reliability of UAVs, Mr. Liu Bin of Northwestern Polytechnic University pointed to the pain point of the industry: at present, the safety and reliability level of domestic UAVs is low. This conclusion sounds a little frustrating

as a safety and reliability research expert in the domestic aviation field, Liu Bin said that most domestic UAV enterprises do not absolutely pay attention to this problem either because of funds or lack of industry background. Nylon material tableland is not easy to absorb sweat. At present, domestic UAV enterprises have not invested enough in this area. To improve the safety and reliability of UAVs, millions of investment is far from enough. In particular, the industry experts' introduction of class I UAV requires a lot of human and financial resources as well as material resources

Liu Bin told that at present, there is no guidance document in this regard in China, and the enterprise has no rules to follow. The United States has long had written regulations on this. The airworthiness certification specifications for civil UAVs in the United States were specified in the airworthiness certification FAA order 8130.34 in 2008. It can be seen that the United States is relatively complete in terms of technical standards for civil UAVs

however, there are still barriers between these standards and whether civil UAVs can fly freely in the sky and whether they can carry out commercial flight activities. The analysis report of the US Department of defense shows that the failure probability of UAV system is 50 times that of F-16 fighter and 100 times that of general-purpose aircraft. Therefore, before the safety of UAV is further improved, the Federal Aviation Administration (FAA) of the United States still holds a conservative attitude towards the wide application of UAV. The airworthiness regulations of the United States on UAVs are formulated according to the airworthiness regulations of general aircraft, which are relatively strict. Liu Bin believes that the safety and reliability of UAVs can only be guaranteed under the strict Airworthiness System

heroes think alike. Xulongtang, deputy general manager of star ring airlines, which is called the new old airline by his peers, agrees with Liu Bin's views. Now in this industry, machines explode and repair when they explode. Then why not prevent in advance and improve the reliability as much as possible at the beginning of UAV design

Xu Longtang, who has been involved in the field of industrial UAVs for many years and is well versed in the development of this industry, talked about some current situations of the industry: after the commercialization is gradually mature, the market ownership has increased, and the accident rate has also increased. However, in the field of UAVs, especially industrial UAVs, it is not enough to change the name of the model aircraft into UAVs. The most important thing for industrial UAV is to ensure reliability and reduce accident rate

xulongtang believes that the uncontrollable factors of UAV are too large to predict the secondary disasters. Compared with the automobile, the secondary disaster of UAV is the barrel effect by changing the proportion of the above three components at the same time. A dozen components may be damaged, but the whole machine may be damaged, and even a third party may be harmed. Hundreds of thousands of components may be gone. Why did you fall? How can this problem be avoided

Xu Longtang stressed that in the absence of industry regulations and provisions, it is very important for UAV manufacturing enterprises to do a good job in the overall design specification of aircraft according to aviation standards at the beginning of product design. The technology and management team of star ring Airlines has a deep aviation background and is familiar with the industry. Take reliability as the basic requirement for R & D and production, and implement it in every link of the company, and strive to make the products as controllable and more reliable as possible through reliable technology and strict specifications In my opinion, the demand of star ring airlines for reliability and efficiency should be put in the first place not only for ourselves, but also for UAV enterprises

in the communication with keyubao, Executive Secretary General of China aircraft owners and Pilots Association, we also learned that the laws and regulations on UAV supervision in China have not yet been issued. At present, only the Interim Provisions on the management of civil unmanned aerial vehicle system pilots and the civil UAV air traffic management measures of the civil aviation administration can be found. The specific rules are vague, and how to apply for and how to supervise need to be further developed

obviously, the Interim Provisions are not suitable for the requirements of unmanned aerial vehicles which are developing very rapidly. Therefore, various ministries and commissions of the state and the Civil Aviation Administration have put forward requirements to comprehensively and comprehensively legislate on unmanned aerial vehicles. The legislation is not only airworthiness, but also comprehensive, involving the design, production, maintenance, operation, air traffic control and nationality registration of unmanned aerial vehicles

it is understood that some regulations and procedures to be issued by the airworthiness department are based on several aspects:

1 definition and classification. Gradually classify from small/light/low to large/heavy/high, and then manage more deeply

2 validation basis. The basis of validation will vary greatly depending on the energy/power situation

3 airworthiness certificate. Should there be any difference in the issuance of airworthiness certificates for unmanned aerial vehicles? There should be different requirements and different certificates for the experimental, verified, recreational, professional flight and passenger and cargo transportation to indicate their purposes

4 management and supervision. The basic idea of CAAC is 1234. 1. Be a pilot unit; 2 establish two systems, one is the pilotless aircraft nationality registration system, the other is the pilotless aircraft airworthiness inspection system. The main purpose of these two systems is to make it very convenient for applicants to apply for various certificates; 3. Prepare to issue three normative documents, one management regulation (Interim Provisions on the airworthiness management of unmanned aerial vehicles), two procedures (management procedures for the issuance of special airworthiness certificates for unmanned aerial vehicles, and management procedures for the issued appointed representatives of the airworthiness of unmanned aerial vehicles); 4. Four kinds of certificates, including chartered flight certificate, special airworthiness certificate (pilotless), restricted airworthiness certificate (pilotless) and standard airworthiness certificate (pilotless)

we look forward to the introduction of relevant specifications as soon as possible. In this empty window period, we appreciate what an expert who has been involved in the industry for many years said that safety and reliability are the lifeline of the aviation industry
