The invention discloses a wing thermal-mechanical coupling deicing device and method. The wing thermal-mechanical coupling deicing device comprises an eddy current heater and a striking force generator. The striking force generator is arranged in the wing, and the eddy current heater comprises a heating metal layer arranged on the skin and an eddy current generating circuit used for being in non-contact connection with the heating metal layer; the eddy current generating circuit is arranged in the skin and can directly act on the heating metal layer; according to the scheme, the periodic accumulated ice on the front edge of the wing is removed through the combined action of the eddy current heater and the pulse force exciter, and in the wing icing allowable envelope range, the further growth of the accumulated ice is avoided, and the safe flight limit of an aircraft is maintained. Compared with a traditional electric heating anti-icing and deicing system, a long-time electrified hot knife electric heating area is omitted, the heating efficiency of an intermittent heating area is improved, the striking force generator is additionally arranged, and due to the fact that the energy consumed by the striking force generator is far smaller than that of a hot knife, the electric power consumption needed by periodic deicing is reduced.

    本发明公开了一种机翼热力耦合除冰装置和方法,包括电涡流加热器和击打力发生器;击打力发生器设置在机翼内部位置,电涡流加热器包括设置于蒙皮之上的发热金属层和用于与发热金属层非接触式连接的涡流发生线路;涡流发生线路设置在蒙皮之内能够直接作用于发热金属层;本方案中通过电涡流加热器和脉冲力激励器的综合作用,将机翼前缘周期积冰进行去除,在机翼结冰允许包线范围内,避免了积冰的进一步增长,维持飞机的安全飞行界限。本发明与传统电热防除冰系统相比,取消了长时间通电的热刀电热区域,提高了间歇加热区域的加热效率,增加了击打力发生器,由于击打力发生器消耗的能量远远小于热刀,本发明降低了周期除冰所需的电功耗。
