Abstract

In flight tests, aircraft moves in real time, so it is important that data from instrumentation/measurement equipment used to determine aircraft status are processed in necessary form and transmitted to flight control systems in real time. Therefore, through telemetry data processing time reduction and processing cycle improvement in flight test control computer data processing system, in order to provide faster slave-data and safety judgment information to radar/telemetry slave-data processing, flight safety analysis system, emergency destruction transmission system, etc., we developed a PCM processing system that can be operated independently by installing data processing software that can receive and process PCM data in current telemetry data processing system and radar information at the same time. In this paper, we explain classified software functions in detail, starting with overall structure of PCM data processing systems developed by supplementing existing systems. Additionally, PCM data processing system will be supplemented through system stabilization and test operation.

비행시험에서 비행체의 경우 실시간으로 빠르게 이동하므로 비행체 상태를 파악하기 위하여 사용되는 계측/측정장비들의 데이터는 비행시험통제시스템들에 필요한 형태로 처리되고 송신되는 것이 실시간으로 이루어지는 것이 중요하다. 그래서 통제컴퓨터 자료처리시스템에서 발생하는 원격측정자료 처리시간의 감소 및 처리 주기의 향상을 통하여 계측레이더/원격측정장비 연동자료 처리, 비행안전 판단시스템, 비상종료 송신시스템 등에 연동자료 및 안전판단 정보를 현재보다 빠르고 유연하게 제공하기 위해 현 운용중인 원격측정자료처리시스템의 PCM 데이터와 레이더 정보를 동시에 수신/처리할 수 있는 자료처리 소프트웨어를 탑재하여 독립 운용이 가능한 PCM 자료처리시스템 을 개발하였다. 본 논문에서는 기존 시스템을 보완하여 개발된 PCM 자료처리시스템의 전체적인 구조부터 소프트웨어 기능을 세부적으로 분류하여 중점적으로 설명하고 있다. 또한, PCM 자료처리시스템은 시스템 안정화 및 시험운영을 통하여 점차 보완해 나갈 것이다.
