PROBLEM TO BE SOLVED: To secure required anti-icing performance while continuing supply of bleed air to an anti-icing device of an aircraft.SOLUTION: An anti-icing system 1 includes: a pre-cooler 4 which performs heat exchange between bleed air and outside air; an anti-icing device 2 which is supplied with bleed air passed through the pre-cooler 4; and an anti-icing controller 11 which adjusts a flow rate of the bleed air supplied to the anti-icing device 2. A section 112 for adjusting the flow rate of bleed air supplied to the anti-icing device 2 adjusts the flow rate of bleed air so that pressure p of bleed air is a pressure upper limit value or less by using: a relationship r1 that is a relationship between altitude and the pressure upper limit value being an upper limit of pressure p of the bleed air; and a relationship r2 that is a relationship between outside air temperature, when a temperature t of the bleed air reaches an allowable temperature AT allowed in a duct and the like in which the bleed air flows, and the pressure upper limit value being the upper limit of pressure p of the bleed air, and that is given according to the altitude.SELECTED DRAWING: Figure 5

    【課題】航空機の防氷装置への抽気の供給を継続しながら、要求される防氷性能を担保すること。【解決手段】防氷システム1は、抽気と外気との間で熱交換させるプリクーラ4と、プリクーラ4を経た抽気が供給される防氷装置2と、防氷装置2に供給される抽気の流量を調節する防氷制御部11とを備える。防氷装置2に供給される抽気の流量を調節する抽気流量調節部112は、高度、および抽気の圧力pの上限である圧力上限値の関係である関係r1と、抽気が流れるダクト等に許容される許容温度ATにまで抽気の温度tが達するときの外気温、および抽気の圧力pの上限である圧力上限値との関係であり、高度に応じて与えられた関係r2とを使用して、抽気の圧力pを圧力上限値以下に収めるように、抽気の流量を調節する。【選択図】図5
