Introduction
Standard Evolution and Technology Upgrade
GB/T 13186-2017 replaces the 1991 version of the standard. The main technical changes include: adding 9 term definitions such as hover indicator, deleting 3 obsolete terms; the navigation accuracy requirement is increased to CEP≤1.4% of the range; and the random vibration test curve (Figure 2) and software function requirements are added.
Analysis of core performance indicators
| Subsystem | Key parameters | Indicator requirements | Test methods |
|---|---|---|---|
| Doppler radar | Speed measurement accuracy | Longitudinal error≤0.25%|Vt|+0.4km/h | 20km horizontal straight flight test |
| Navigation computer | Data storage | ≥100 waypoints+20 route points | Power-off data retention verification |
| Hover indicator | Indication accuracy | Lateral±2.5km/h | Tested by special tester |
Environmental adaptability requirements
Typical application scenarios: According to the classification in Appendix A, Class C2 equipment must work normally at an altitude of 10,700 meters and in an environment where the temperature is not controlled. The test must comply with the following:
- Low temperature operation: -55℃ (Table 1)
- Random vibration: 10-2000Hz power spectrum density 0.0005g²/Hz (Table 5)
- Salt spray test: No corrosion for 48 hours (4.11.10)
Implementation suggestions
- Electromagnetic compatibility design:Requirement 4.14 requires MIL-STD-461 equivalent testing during the R&D stage
- Reliability verification:It is recommended to use MTBF ≥ 5000 hours as the basic indicator (4.15)
- Software verification:It is necessary to establish a V model development process according to GB/T 15532 (5.17)
