当前，传统飞机液压刹车系统普遍采用集中式的机载液压源作为动力，液压能通过能源管路传输到刹车作动器，整个系统零部件数目众多，管路布局复杂，由此带来的管路振动、液压油泄漏等问题突出，限制了飞机刹车系统可靠性和可维护性的提升。近年来，一种飞机新原理电液自馈能刹车系统被提出，将模块化的"自馈能装置"安装在机轮附近，回收机轮着陆时的旋转动能，并将其转换成液压能，用于刹车作动。提出了一种利用波浪曲面进行取能的专用取能机构，设计了自馈能系统紧凑型专用取能机构，研制了高可靠、低能耗、高抗污染的自馈能刹车系统原理样机，完全实现了自馈能，即使飞机失去全部动力也能正常完成刹车功能，使抗污染等级从NAS6级提升到NAS10级，可靠性和可维护性优于传统液压刹车。
At present, the traditional aircraft hydraulic brake system typically uses the centralized airborne hydraulic source as the power, which is transmitted to the brake actuator through the energy pipeline. With many parts and components and complex pipeline layout, the system has many problems, such as pipeline vibration and hydraulic oil leakage, limiting the improvement of reliability and maintainability of the system. In recent years, a new principle for aircraft electro-hydraulic self-powered braking system has been proposed. The modular "self-powered device" is installed near the wheel to recover the rotational kinetic energy of wheel landing and convert it into the hydraulic energy for braking. In this paper, a special mechanism using the wave curved surface for energy taking is proposed, which breaks through the stalemate with the design of a special energy taking mechanism for the self-powered system. A fully self-powered brake system principle prototype with the features of high reliability, low energy consumption, and anti-pollution is developed. Even if the aircraft loses all power, it can still effectively brake the plane. In addition, the anti-pollution level is upgraded from NAS6 to NAS10. The Integrated Self-powered Brake System (ISBS) is demonstrated to be better than the traditional hydraulic brake in terms of reliability and maintainability.
