Problems solved by technology

Its main disadvantages are: expensive, non-reusable, large current at the moment of ignition, and may cause a short circuit in the ignition circuit after ignition
Due to the high cost of pyrotechnic products, non-reusable use, long procurement and transportation cycle, high cost, and multiple ignitions during the test, the requirements for the management of the test site and the test environment are high, and a lot of manpower, material resources and processing time are wasted.

Abstract

The invention relates to a simulating device of the ignition electric property of an igniter and a method thereof, which belong to the test technique of an electric network of an aircraft. The simulating device comprises a program controller, a programmable direct current power supply A, a programmable direct current power supply B, a power converting control box and a GPIB control module, wherein the program controller is provided with an LabView visual instrument software development platform capable of developing programmable software; the GPIB control module is a USB converting GPIB bus control module; and the power converting control box is used for controlling power supply in a manual mode. Different line drops generated by current change can be simulated by voltage change by the device and the method; and a test process does not have a large current phenomenon and can be repeated. The invention has the advantages of high safety and economy and is especially suitable for carrying out an ignition verification test on an aircraft.

Description

technical field [0001] The invention belongs to aircraft electrical network test technology, in particular to a simulation device and method for ignition electrical characteristics of pyrotechnic products. Background technique [0002] The pyrotechnic product is a device that detonates, ignites energy and provides work. It is one of the indispensable main power devices on the aircraft. When working, the internal electric ignition head responds to the aircraft's timing ignition electrical signals and stimulates the internal chemical fire of the pyrotechnic product. Components to meet the working environment of aircraft-related components. Its main disadvantages are: expensive, non-reusable, large current at the moment of ignition, and may cause a short circuit in the ignition circuit after ignition. In order to assess the adaptability of each sub-system component of the aircraft to the characteristics of the power supply, the aircraft electrical network test must be carried ...
