Embodiment Construction
[0034] Embodiments of the present invention are described in detail below, and the embodiments are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0035] A certain type of engine nozzle state control box JKQ-12 product is used to collect engine rotor speed signal n2, nozzle state signal, throttle lever state signal and engine working mode signal, and judge whether to send an alarm signal according to the state of the two, and the alarm signal passes through the main engine on the machine. The warning lights and nozzle fault lights give warning indications and send signals to the flight parameters at the same time. When an alarm occurs, if it is detected that the main warning light is flickering, the strobe signal will not be sent to the main warning light, and only the "nozzle fault" equipment warning light will be highlighted. If the main warning light has no stroboscopic signal, a strobe The flashing s...

The invention provides an engine nozzle state control box tester and a testing method. The tester comprises a power supply module, a display module and a trigger module. The display module comprises acentral warning lamp and a nozzle fault lamp. The trigger module comprises switches for simulating and generating alarm signals and corresponding time delay relays; the switches for generating the alarm signals are divided into a signal switch with a throttle lever greater than or equal to 100 degrees, a signal switch with an engine rotating speed greater than or equal to 66%, a signal switch with an engine rotating speed greater than or equal to 70%, a signal switch with a throttle lever less than 73 degrees, an emergency stress application signal switch and a nozzle opening signal switch. Corresponding alarm conditions are realized through switch control and signal input, various display modules on an airplane are restored, delay data in the product testing process are digitized throughthe delayer, the product performance detection function is realized, and the testing requirement of the product engine nozzle state control box is met.
Description
technical field [0001] The invention relates to the technical field of engine nozzle state control box testing, in particular to an engine nozzle state control box tester and a test method. Background technique [0002] The engine nozzle state control box is the key equipment for controlling the state of the engine nozzle on the aircraft, and it needs to be tested according to the test requirements in aircraft maintenance support. At present, in the process of repair and guarantee, the control box product is disassembled and then tested by short-circuiting. This test method is simple, has a high risk factor, is easy to damage the product, and the test process is relatively complicated, which seriously affects the production cycle. Contents of the invention [0003] In order to solve the problems existing in the prior art and meet the test requirements of the current control box for the nozzle state of a certain type of aircraft engine, the present invention proposes a test...
