Zusammenfassung:	The invention relates to the field of turbomachine blades, and more specifically to a leading edge shield (32) for a turbomachine blade (16), which comprises a lower canopy fin (34) and an upper canopy fin (36), each extending in the height and length direction and connected together along their height, the lower canopy fin (34) having a greater length than the upper canopy fin (36) over a first segment (SI) of the leading edge shield (32), and a length equal to or lower than the upper canopy fin (36) over a second segment (S2) of the leading edge shield (32). 本发明涉及涡轮机叶片领域，更具体地涉及用于涡轮机叶片(16)的主边缘护罩(32)，该主边缘护罩(32)包括下盖翅片(34)和上盖翅片(36)，每个翅片均沿着高度和长度方向延伸，并沿着它们的高度连接在起，该下盖翅片(34)在主边缘护罩(32)的第部分(S1)上的长度大于上盖翅片(36)的长度，在主边缘护罩(32)的第二部分(S2)上的长度等于或小于上盖翅片(36)的长度。
