Aircraft cockpit command and control system simulation test device and external equipment

Abstract

In order to carry out low-maintenance-cost and convenient-to-implement tests on radar reflection conditions of an aircraft cockpit command and control system under interference conditions, the invention discloses an aircraft cockpit command and control system simulation test device and an external device thereof. The simulation test device comprises an aircraft radar (1), a shielding cage (2), a test board (3) and a plurality of test wires (4). The external equipment comprises a first electromagnetic interference generation unit (5) and a second electromagnetic interference generation unit (6), the test board (3) is arranged in the shielding cage (2), the aircraft radar (1), the first electromagnetic interference generation unit (5) and the second electromagnetic interference generation unit (6) are arranged outside the shielding cage (2), each of the plurality of test wires (4) comprises two wiring terminals, one end of each wiring terminal is connected with the test board (3), and the other end of each wiring terminal is connected with a flight attitude control signal output end of an aircraft cockpit command and control system.

Description

technical field [0001] The invention relates to a test and simulation equipment, more specifically, to a simulation test device and external equipment of an aircraft cockpit command and control system. Background technique [0002] Aircraft cockpit design is the most complex design project except for the engine on aircraft such as fighter jets and civil aviation airliners. The safety of the pilot and the reliability of the control of the performance of the aircraft body must be guaranteed to avoid various internal and external factors. It has no negative impact on safety, and ensures access to many instruments and many basic control devices set up in a limited space, and is easy to operate. In particular, the cockpit command and control system of a fighter jet is the "brain" of the airframe. It adopts technical equipment with an onboard computer as the core to carry out integrated control of the flight control system, communication system, navigation and positioning system, ...

Problems solved by technology

However, this method significantly increases the test cost of the aircraft cockpit control system, and also brings that when the model is upgraded or the cockpit control system is upgraded or changed, the corresponding electromagnetic interference reliability test procedures need to be specially adjusted and rigorous. testing, which brings a significant increase in program development costs
