TL;DR: In this article, a fine-net structural design for a fan blade was proposed to improve the work safety of an aero-engine by controlling the deformation of the fan blade during bird impacts.
Abstract: The invention relates to a bird impact design method for a fan blade, belongs to the technical field of aviation and provides a bird impact design method for a fan blade. The sub-surface fine net structural design is conducted on the blade, elastic deformation of the fan blade due to bird impacts or foreign matter collisions is controlled, the effects of inner structure dislocation energy absorbing and breaking energy absorbing are achieved, and the purpose that the blade is greatly deformed but not fractured is achieved to the maximum degree. Even though the blade is fractured, the fracture position and trend can be controlled through the design method, risk controllability is achieved, and the safety of the fan blade is improved to the maximum degree. Through the inner design, effective control and prediction over blade fracture during bird impacts can be achieved, and the work safety of an aero-engine is improved.

TL;DR: In this paper, a helicopter blade bird strike performance test verification method is presented, which comprises the following steps of: the step 1: selecting at least blades in helicopter blades as test pieces, patching strain gages at the strike section area of each test piece, and installing one acceleration sensor near the strike area of the test piece; the step 2: installingeach test piece to simulate the installation state, and the step 3: applying the loaded environment when flight performance is simulated; step 4: performing bird shot test debugging; step 5: performing checking after a bird strike
Abstract: The present invention discloses a helicopter blade bird strike performance test verification method. The method comprises the following steps of: the step 1: selecting at least blades in helicopter blades as test pieces, patching strain gages at the strike section area of each test piece, and installing one acceleration sensor near the strike section area of each test piece; the step 2: installingeach test piece to simulate the installation state of each test piece; the step 3: applying the loaded environment when flight of each test piece is simulated; the step 4: performing birdshot test debugging; the step 5: performing checking after a bird strike test is performed; and step 6: performing a fatigue life test and performing assessment after the bird strike test is performed. The helicopter blade bird strike performance test verification method provides a helicopter bird strike flight safety verification method, and therefore the helicopter flight safety can be improved.

TL;DR: In this article, a horizontal ejection-impact type blade cutting test device was presented, which consisted of an air cannon, projectiles launched by the air cannon and a slideway, an impulse conversion device, a test blade and a test bird body.
Abstract: The invention discloses a horizontal ejection-impact type blade bird cutting test device. The device comprises an air cannon, projectiles launched by the air cannon, a slideway, an impulse conversiondevice, a test blade and a test bird body, wherein the impulse conversion device serves as an impulse conversion medium, the impulse of the shots launched by the air cannon is transferred into the test blade, and the process that the test blade impacts the test bird body is used for simulating blade bird cutting. As the projectile does not directly impact the test blade and does not need to directly hit the test blade from a gun barrel, different types of bird impact blades are simulated by impacting the test bird body with the test blade, and convenience and accuracy of the bird impact resistance blade test method are improved. The invention further provides a test method using the test device.
