P2T2传感器，算EPR的参数

mrlynch · 发表于 2017-11-16 15:23:06

P2/T2 SENSOR
The P2/T2 sensor is located near the 12 o'clock position of the inlet cowl. It measures total pressure and temperature in the inlet air stream of the engine forward of the engine front flange. The dual output total temperature measurement is accomplished by two resistance-sensing elements housed in the P2/T2 sensor body. Each channel of the Electronic Engine Control (EEC) monitors one of these resistance elements and converts the resistance measurement to a temperature equivalent. The total gas pressure is transmitted by the pressure tubing and measured by the sensor located in channel A of the EEC. The anti-icing function of the P2/T2 sensor is provided through a heating element internally bonded to the sensor. The heater is a hermetically sealed, coaxial resistance element brazed internally to the sensor casting. Aircraft power, which is used for the heater, is switched on and off by the EEC, via the relay box.

顺便问一下 cfm的是个圆柱形的东西也是这个功能吗

十楼正解，补充一下，CFM不用算P2因为CFM没有EPR模式，推力表征是N1

v2500和cfm的不大一样。cfm是柱子状的。只能探测温度，在消音版的一圈有一共三个小点是测进口压力的。而v2500一根就包括了这两个功能

playboy88 · 发表于 2018-7-20 22:37:23

这个是P2/T2传感器，用以测量发动机进口的总温和总压，结合发动机排气压力P4.9就可以计算出表征V2500发动机推力的主要参数EPR了。EPR=P4.9/P2

P2 / T2传感器
P2/T2传感器位于进气罩的12点位置附近。测量发动机前翼缘进气口气流的总压力和温度。双输出总温度测量是由位于P2/T2传感器体中的两个电阻传感元件完成的。电子发动机控制(EEC)的每个通道都监视这些电阻元件中的一个，并将电阻测量转换为温度当量。总气体压力通过压力管传递，并通过位于其中的传感器进行测量

V2500发动机上有这个，P2T2传感器探头。

你好，这个叫T12探头，是一种温度传感器。

武心 · 发表于 2018-11-19 13:38:07

学习了。新款的发动机PW1100G好像也不测压力。
