GROUND REPLAY EQUIPMENT OF SOLID STATE FLIGHT DATA RECORDER OF JAGUAR MK II amp; MIG27 UPG

摘要

The Ground Replay Equipment (GRE) is a laptop based Ground Handling System which is capable of retrieving Aircraft & Audio Data as recorded in Data Retrieval Unit(DRU) through Ethernet interface. Speed of replayed data is at least 25 times of AIc data recording time for both SSFDR of JAGUAR and MiG27 and 10 times of Audio (for JAGUAR MK II only) recording time. The replay is done based on Sortie count stored in DRU. The recorded raw data extracted from DRU is then processed by GRE in prescribed format which will be stored in laptop for post flight data analysis. The analysis of Aircraft data is done either in graphical or tabular mode with the help of GRE software. It also replays the audio data stored in DRU in synchronization with parameter data (for Jaguar MKII). GRE software provides a user-friendly interface to select the parameters for analysis, scales the data into the required format and saves in the hard disk or prints on a printer. The GRE system has been designed and developed on GUI based system software platform with Visual C++ programming language. Using capabilities of programming language and code of practice of C++ the Ground Replay Equipment Software has been developed to meet the user requirements. The major requirements are to analyze aircraft and audio(for Jaguar MKll ) data as recorded in the DRU. This analysis shall be capable enough for health monitoring of the aircraft as well as fault diagnosis. The analysis would be both in Tabular and Graphical display format.
