Problems solved by technology

[0003] At present, our factory does not have this kind of calibration equipment, so we cannot test the various functions and detailed technical indicators of this kind of horizon instrument before installation, and adopt direct installation; when the machine is powered on to check that the product fails, we cannot quickly judge that it is the horizon instrument itself The fault is still the fault of the on-board circuit or other cross-linking equipment, which can only be solved on the plane, and the fault phenomenon cannot be reproduced on the ground

Embodiment Construction

[0014] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] Such as figure 1 As shown, a kind of horizon instrument tester is by the first single-pole single-throw switch S1, the second single-pole single-throw switch S2, the first fuse F1, the second fuse F2, the first ammeter A1, the second ammeter A2, test hole Va, Composed of Vb, Rx, Ry, Rz, Px, Py, Pz.

[0016] The positive terminal of the 28-volt regulated power supply is connected to the positive terminal of the DC power supply of the plug of the horizon instrument through the first ammeter A1 through the first single-pole single-throw switch S1 and the first fuse F1, and the negative terminal of the 28-volt regulated power supply is connected to the plug of the horizon instrument for DC power supply The negative terminal of the power supply is connected for DC power supply. The high end of the 26V / 400Hz AC power supply is connected to the high end of the AC e...

Abstract

The present invention belongs to the technical field of aircraft testing. The horizon sensor tester is characterized by comprising a first single-pole single-throw switch S1, a second single-pole single-throw switch S2, a first fuse F1, a second fuse F2, a first ammeter A1, a second ammeter A2, and testing holes Va, Vb, Px, Py, Pz, Rx, Ry and Rz. According to the present invention, with the horizon sensor tester, the horizon sensor can be subjected to power consumption check, warning flag retracting time check, indication precision check, synchronizer output check, directivity check, correction speed check, correction incisal angle check and rotor stop time check so as to completely detect various performance indexes of the product.

Description

Background technique [0001] The invention belongs to the technical field of aircraft testing. [0002] current technology [0003] At present, our factory does not have this kind of calibration equipment, so we cannot test the various functions and detailed technical indicators of this kind of horizon instrument before installation, and adopt direct installation; when the machine is powered on to check that the product fails, we cannot quickly judge that it is the horizon instrument itself The fault is still the fault of the on-board circuit or other cross-linking equipment, which can only be solved on the plane, and the fault phenomenon cannot be reproduced on the ground. [0004] purpose of the invention [0005] A horizon tester can comprehensively detect various performance indicators of the product, adopts external general equipment, reduces cost, simplifies design, has higher reliability of the tester, and avoids repeated construction of the laboratory. [0006] conte...
