Apparatus and method of pressure drop simulation for avionics

摘要

PURPOSE: A device and method for simulating pressure drop characteristics of avionics are provided to accurately detect a flow rate not only in a high-speed area but also in a low-speed area by comprising a flow meter directly detecting the flow rate. CONSTITUTION: A device(10) for simulating pressure drop characteristics of avionics comprises a duct(11), a temperature sensor(12), a pressure sensor(13), a flow meter(14), and a conical valve(15). A cooling fluid generated in an environmental control system of aircrafts for cooling avionics through the duct. The temperature sensor detects a temperature of the cooling fluid flowing inside the duct. The pressure sensor detects a pressure of the cooling fluid flowing inside the duct. The flow meter directly detects a flow rate of the cooling fluid flowing inside the duct. The conical valve controls a flow of the fluid to simulate pressure drop characteristics of the avionics based on values detected by the temperature sensor, the pressure sensor, and the flow meter.
