introduction
GB/T 44821 "General Technical Requirements for Stratospheric Airships" was formulated to establish a unified system for the development, production and use of stratospheric airships.
Standards will promote the healthy and rapid development of the stratospheric airship field, so as to better meet and serve the economic construction and security needs of my country's near-space.
GB/T 44821 is intended to consist of two parts.
Part 1.Environmental Control System. The purpose is to propose general technical requirements and verification for the environmental control system of stratospheric airships.
The testing as well as labeling, packaging, transportation and storage requirements provide a basis for the design and manufacture of stratospheric airship environmental control systems.
Part 2.Propulsion System. The purpose is to propose general technical requirements, verification tests and
Labeling, packaging, transportation and storage requirements provide a basis for the design and manufacture of stratospheric airship propulsion systems.
General technical requirements for stratospheric airships
Part 2.Propulsion System
1 Scope
This document specifies the composition, function, performance, interface, environmental adaptability,
Technical requirements such as safety, reliability, maintainability, testability, and security, as well as corresponding verification test requirements.
This document is applicable to the design and manufacture of propulsion systems for stratospheric airships driven by pure electric means, and other airships driven by pure electric means,
The propulsion systems of high-altitude balloons and solar-powered aircraft are used for reference.
