研制的传感器可用于测量气轮发动机中的高达1700℃的温度。因恶劣的温度、压力和振动环境,精确地测量气轮发动机中的温度是困难的,测量气轮发动机燃烧室释放出的气体温度之所以特别困难,是因为气体的主要成分是由矿物燃料燃烧的热的活性化学物组成。现用的光学温度计中的敏感元件(DILS.NBC)是一块薄片单晶蓝宝石,用一个有涂层的尖头形成一个黑色空腔,当浸入气流中时,
Developed sensor can be used to measure the temperature of the gas turbine engine up to 1700 ℃. It is difficult to accurately measure the temperature in a gas turbine engine due to adverse temperature, pressure and vibration conditions. It is particularly difficult to measure the temperature of gas released from a gas turbine engine combustion chamber because the main component of the gas is burned by fossil fuel Of the hot active chemical composition. The sensitive element in the current optical thermometer (DILS.NBC) is a thin sheet of single-crystal sapphire that uses a coated tip to form a black cavity that, when immersed in a gas stream,
