This invention relates to the field of aircraft structural design technology, specifically to a leading-edge tower-type bird strike protection structure for aircraft. It includes a leading-edge skin assembly, a first protective assembly, a second protective assembly, a third protective assembly, and a rear beam assembly. The leading-edge skin assembly and the rear beam assembly are located at the front and rear ends of the sequentially connected first, second, and third protective assemblies, respectively, and are wrapped around them. The rear end of the first protective assembly is fixedly connected to the front end of the second protective assembly and is used to resist high-speed bird impacts. The rear end of the second protective assembly is fixedly connected to the front end of the third protective assembly and is used to resist medium-speed bird impacts. The rear end of the third protective assembly is fixedly connected to the rear beam assembly and is used to resist low-speed bird impacts. The purpose of this leading-edge tower-type bird strike protection structure is to solve the problem of low structural efficiency in existing aircraft leading-edge bird strike protection structures.
