Standards Development

Scope

This proposal mainly proposes general requirements for vibration tests in environmental tests for civil lightweight and small UAS, which includes the classification of the power platform of the UAS, the vibration environment characteristics and the typical vibration environmental conditions of each power platform, the typical vibration test methods and test procedures, the general requirements for vibration test equipment and the evaluation methods of the vibration test results, etc.

The classification of the power platform of the UAS gives the corresponding classification principle and description. The typical vibration environment conditions of each power platform give the method and description of the vibration test conditions. The evaluation method of the vibration test results gives the principle for determining the qualification criteria and the method of fault analysis.

Purpose

In recent years, the market for civil lightweight and small UAV has developed rapidly. Breakthrough developments have been made in areas ranging from consumer-grade aircraft cameras to industrialgrade UAVs, such as agriculture, electricity and public safety. However, there are no environmental test standards for civil lightweight and small UAS at home and abroad. The developers and manufacturers of civil unmanned aerial vehicles are mostly based on their own experience, with reference to the test requirements of other similar aircraft abroad, or by reference to the national standards of environmental tests for environmental test assessment. There are no uniform standards for the selection of environmental test items, test conditions and test methods, and there is also a lack of comprehensive analysis of the practical application requirements and operating environment of civil lightweight and small UAS. Moreover, the civil light and small UAS is quite different from civil aircraft and other aircraft in terms of use environment, mission characteristics, safety and so on. It is easy to cause inadequate test evaluation by referring to the corresponding standards directly, which will affect the operational use, flight safety and delivery guarantee of civil light and small UAS. This proposal will set a baseline for the industry and form an environmental test standard for civil light and small UAS, which will play a positive role in promoting the environmental adaptability of the civil UAV industry. 1The requirements of the vibration test will improve the safety of the light and small UAS. 2For the UAS manufacturer, this standard will increase the ability of the UAS to withstand vibration, improve the safety of product, and control the choice of accessories.

3For accessory manufacturers, this standard will give an entry condition for entering the UAV industry.

4For the customer, unified standards will reduce the difficulty of operation and maintenance, and results in a better user experience. 5For regulators, standardized vibration tests will provide the necessary interface for the supervisory system. This will improve the safety of the UAS.

Consider the following: Is there a verified market need for the proposal? What problem does this standard solve? What value will the document bring to end-users?
