Embodiment Construction

[0012] Attached below figure 1 The present invention is described in detail:

[0013] A barometric altitude simulator is provided with a static pressure hole 1, a full pressure hole 2, and an aviation plug 3 at the outer end of the simulator;

[0014] A pump combination 4, a liquid crystal display module 8, a sensor combination 9, a power supply combination 10, a volume combination 11, and an air release valve combination 12 are arranged inside the simulator;

[0015] A fixed plate 6 is also arranged inside the simulator, and a multi-way block assembly 5 and a valve assembly 7 are arranged on the fixed plate 6 .

[0016] Multiple series-parallel compression and pressurization units are driven by a high-power transmission mechanism to realize the integrated design of the vacuum pump and the compression pump; the gas circuit structure is realized by three-dimensionally assembling the control valve, pipeline, gas circuit filtration, dehumidification and other parts The three-di...

Abstract

The invention relates to a pressure altitude simulator and belongs to the technical field of structure design of pressure altitude simulators. A static port, a total port and plug-in holes are formed in the outer end of a simulator body. A pump assembly, a liquid crystal display module, a sensor assembly, a power source assembly, a volume assembly and a deflation valve assembly are arranged inside the simulator body. A fixing plate is further arranged inside the simulator body, and a several-piece assembly and a valve assembly are arranged on the fixing plate. Under the condition that the function and performance of equipment are not damaged, the functions of all units inside the pressure altitude simulator and the structure of the pressure altitude simulator are reasonably adjusted, so that the equipment is reduced to 4U at present from original 8U, and the miniaturization design of the pressure altitude simulator is achieved; meanwhile, due to the fact that functional modules of the simulator are integrated and the structure is simpler after adjustment, production and maintenance cost is correspondingly reduced, and the demands of users for miniaturization and low cost of test equipment are met.

Description

technical field [0001] The invention relates to a barometric altitude simulator, which belongs to the technical field of barometric altitude simulator structural design. Background technique [0002] The barometric altitude simulator is an instrument for measuring and setting atmospheric data. Generally, it can be directly used to measure atmospheric data, or set the set values ​​of barometric altitude and indicated airspeed through the host computer (or this machine), and output the corresponding pressure. It realizes the inspection of performance indicators such as air tightness, measurement accuracy, and Mach number accuracy of the aircraft air data system. Its internal structure is generally composed of a processor system and control circuit, a pneumatic control unit, a standard pressure sensor unit, and a pressure source. At present, the barometric altitude simulators on the market generally adopt a structure in which the control part and the air source part are separa...
