Introduction
Analysis of Standard Technical Framework
| Core Elements | Explosive Rocket | Parachnical Rocket |
|---|---|---|
| Wreckage Recovery Method | Explosive Self-destruction | Parachnical Recovery |
| Special Inspection Items | Fragment Size + Flight Test | Parachute Opening Time + Flight Test |
| Safety Risk Level | Level 2 | Level 1 |
Detailed Explanation of Key Acceptance Indicators
4.4 Dimensional Inspection requires a straightness deviation of ≤0.5mm for the rocket body, using a laser coaxiality measuring instrument. During one inspection, batch 2019-03 was reworked due to runout exceeding the standard by 0.2mm.
4.8 Flight Test specifies: trajectory yaw angle ≤5°, catalyst seeding duration ≥15 seconds. This data directly relates to clause 3.3.2 of QX/T 359-2016.
Key Points for Standard Implementation
- Document acceptance must include an interior ballistic test report and closed-loop certification of major quality issues
- Electrical performance testing requires the use of an insulation resistance tester (accuracy 0.1MΩ)
- Flight test sampling follows the S-3 special inspection level of GB/T 2828.1
Technology Evolution Analysis
Compared with the 2008 version of the pilot standard, the main changes in this revision are:
- Added QR code traceability system requirements (4.3.3)
- Referencing the correlation between fragment size and QX/T 359 (4.7)
- Clarifying the echolocation detection method in cloudy environments (5.8.3)
