GB/T 38152-2019 in English

GB/T38152-2019 is the basic terminology standard in the field of UAVs in my country. It has systematically constructed a terminology framework for nine categories, including fixed-wing UAVs and rotary-wing UAVs. The standard text is 93,000 words, clearly defining key concepts such as basic terminology, airframe structure, and airborne systems.

Chapter 2.2 of the standard specifies in detail the definition methods of 16 performance parameters:

• Maximum take-off weight: critical value based on structural strength limitation
• Control radius: comprehensive consideration of real-time measurement and control distance and range
• Hovering ceiling: distinguish between in-ground effect and out-of-ground effect conditions

Taking a multi-rotor UAV as an example, its wheelbase is defined as the center distance between the drive shafts, which directly affects flight stability.

R&D applications

It is recommended that enterprises refer to the definition of 2.2.17mission radius and incorporate energy systems and communication links into integrated design.

Testing and certification

According to 3.1.2resonance, rotorcraft UAVs need to add ground resonance test items.

Regulatory compliance

6.2mission load classification can be used as a technical basis for airworthiness review.

Compared with the international standard ISO 21384-1, GB/T38152-2019 innovatively:

1. Added Chinese-style classifications such as compound rotor UAVs
2. Refined the evaluation dimension of data link functional performance
3. Introduced the 10.3 regulatory terminology system

This standard forms a technical support with the CCAR-92 regulations, and together they build the cornerstone of my country's UAV standard system.
