Since all the probes and vanes are exposed to the airstream, internal heating is provided to prevent ice formation. Freezing could cause faulty inputs or possible loss of all data.皮托靜壓探頭、總溫探頭和迎角葉片用來提供大氣數(shù)據(jù)信息給不同的應(yīng)用系統(tǒng)，他們位于前機(jī)身在右側(cè)。(3) The wing antiice system prevents ice buildup on the wing leading edge slats, this system consists of air supply ducts, valves, terminal switches, controls and indications.防冰系統(tǒng)可防止冰在縫翼前緣堆積，此系統(tǒng)包括供氣管道、活門、終端開關(guān)、控制及指示器。雨刷和防雨劑用來提供清晰視野。(2) Wing leading slats use hot air from the pneumatic system. Flight partment windows are electrically heated. The wipers and rain repellent are used for providing clear vision. The pitot static probes, alpha vanes, drain masts, and toilet drains use electric heaters.前緣縫翼用增壓系統(tǒng)的熱引氣加溫。LESSON 7 ICE AND RAIN PROTECTION防冰、防雨一、單詞雨Rain保護(hù)Protect幫助Aid為…而提供Is provided for雨刷Wiper防雨劑Repellent葉片Vane衛(wèi)生間Toilet排放Drain視線Vision皮托靜壓Pitot static探頭Probe迎角葉片Alpha vane支柱管Mast堆積Buildup碰撞Impact強(qiáng)度Strengthen霧Fog導(dǎo)電的conductive涂層coating暴露expose氣流Airstream形成Formatting結(jié)冰Freeze原因Cause出故障的Faulty損失Loss槽Sink嵌入Embed墊圈gasket裝置fitting與…結(jié)合在一起Are integrated with二、TEXT(1) the ice and rain protection system protects the airplane and aids the flight crew when operating under ice and rain conditions.
