Abstract

According to the FPGA-based atmosphere data processing module provided by the invention, the FPGA-based universal and high-reliability miniaturized atmosphere data module is constructed, and the FPGA-based atmosphere data processing module has the advantages in the aspects of size, weight, power consumption and the like; the weight of an air path pipeline is reduced by adopting a mounting mode close to the air pressure probe; electronic equipment is not combined with a low-reliability mechanical probe and a heater for use, so that the reliability is remarkably improved; according to the invention, the sensor stability is excellent, the supply and spare part rate of a fleet is reduced, and the maintenance cost caused by regular precision inspection is reduced; through independent airworthiness evidence obtaining, the system can be matched with civil aviation aircrafts and general aviation aircrafts.

Description

technical field [0001] The invention belongs to the technical field of aerospace air data measurement, and in particular relates to an FPGA-based air data processing module. Background technique [0002] The air data module is the core module for building a low-cost, distributed air data system, and it is a key device for converting air pressure signals at the front end of the air data system, and it is an LRU in the air data system. The air data module digitally sends temperature-corrected pressure information to the air data resolving unit (ADRU), flight control system, or modular avionics unit (MAU). [0003] The air data module is an important module for the development of modern civil aircraft to high-precision integrated air data, and it is the main trend with the development of avionics equipment in the direction of integration, standardization, digitization, and multi-function. In the future, it will be widely promoted and applied on commercial mainline airliners, d...
