Analysis and Evaluation of Flight Result of Launch Vehicle

1 Scope

China's national standard for the analysis and evaluation of launch vehicle flight results. It specifies the general requirements for that evaluation, the requirements for the analysis carried out by the overall design organisation and by each subsystem, and the requirements for the resulting assessment, and it applies to the analysis of the results of launch vehicle flight tests and of operational launches. Every launch produces a very large quantity of data - telemetry from every subsystem, external trajectory measurements, ground observations - and the flight is over in minutes while the analysis takes weeks. What the standard governs is what happens to that data afterwards, and its importance comes from a fact peculiar to launch vehicles: each flight is both a delivery and a test. The vehicle is expendable, so nothing comes back to be examined; the only evidence of how it behaved is the data it transmitted while it was working. And the same design will fly again, so the analysis of this flight is the principal input to the confidence placed in the next. The standard divides the work between the overall design organisation and the subsystems, and it defines both. The overall system is the collective of units performing top-level design - trajectory, guidance and accuracy analysis, attitude control, electrical, structural, separation, aerodynamic and thermal environment, mechanical environment, propulsion and ground systems. The subsystems are those that receive the overall requirements and implement one aspect: control, measurement including telemetry and external trajectory and range safety, propellant utilisation, and the propulsion system including engines and pressurisation. Each analyses its own performance, and the overall organisation reconciles them into a judgement about the flight. Issued on 31 December 2015 and in force since 1 July 2016.

This standard specifies the general requirements for the evaluation of the results of the launch vehicle, the analysis of the overall and sub-system analysis and the results of the assessment Claim. This standard applies to carrier rocket flight test and application launch results analysis.
