本规范涵盖了用于固定翼和旋转翼飞机（包括倾转旋翼）的耐碰撞、耐弹道燃料电池的要求和验证试验。燃料电池尺寸、总重量和接口要求等精确设计标准将取决于合同或采购订单中规定的预期飞机。

This specification covers the requirements and verification testing for crash-resistant, ballistic-tolerant fuel cells for use in fixed wing and rotary-wing aircraft (including tilt rotor). Exact design criteria such as fuel cell dimensions, total weight, and interface requirements will be dependent upon the intended aircraft specified in the contract or purchase order.
