Introduction
Standard Framework and Technological Evolution
As the third part of the GB/T39315 series of standards, this document constructs a standardized description system for aviation material data. Its technological evolution presents three major characteristics:
- Adopts the Metadata Registration System (MDR) framework and inherits the metadata management concept of GB/T18391.1-2009
- Innovatively establishes a "shared + dedicated" two-layer data model structure to meet the management needs of multiple categories of aviation materials
- Introduces dynamic relationship identifiers (X-type data elements) to achieve intelligent association of model-drawing number-component number
Comparison of core data models
| Model type | Key data element | Required requirements | Typical application scenarios |
|---|---|---|---|
| Shared model | Model (H0001A0000), Sealed status (H0029A0000) | Class B is required | Basic information management of aviation materials |
| Electronic products | Transmitting power (H0121A0000), Resolution (H0123A0000) | Class A is optional | Airborne communication equipment management |
| Mechanical products | Piston rod diameter (H0140A0000), Braking efficiency (H0086A0000) | Conditions are required | Landing gear system maintenance |
| Electrical products | Working voltage (H0065A0000), oil-discharge voltage (H0190A0000) | Class B is required | Avionics system support |
Key implementation points
Mutually exclusive rules for data element values
Article 7.2 of the standard clearly stipulates the mutually exclusive relationship between the four groups of identifiers:
- When Model (H0001A0000) exists, other identifiers can be empty
- No model but Drawing number (H0002A0000), component number must be empty
- Only when all three are missing, Specification (H0004A0000) becomes a required item
Special model extension principle
Special attention should be paid to instrument product models:
- Signal output type (H0068A0000) must match measurement method (H0105A0000)
- When working pressure (H0089A0000) exceeds 10MPa, alarm pressure value (H0102A0000) must be filled in simultaneously
Application value of military-civilian integration
Through the unified coding system (JMH prefix + 5 digits), this standard achieves:
- Civilian class=instrument>Data exchange between aviation material suppliers and military support systems
- Precise matching of specification parameters during wartime emergency procurement
- Complete transfer of technical status when retired military products are converted to civilian use
