一些风能概念利用包含轻于空气的气体的机载系统，其补充气动升力并扩展这些系统的可用操作状态。虽然轻于空气的系统可以结合其轻于空气的对应物的牵引和逆风飞行运动，但几种轻于空气的概念也被设计成在完全静止的操作下提供大量的功率，并在间歇性风期间保持在高处。本章概述了LTA空中风能概念的历史，包括设计驱动因素和主要设计约束。然后重点转向轻于空气系统背后的结构和空气动力学设计原则，沿着必须解决的基本飞行动力学原则。Altaeros能源公司开发的原型设计作为这些原则的应用的一个例子进行了研究。本章最后提出了未来研究的建议，以实现商业上可行的长期协议系统。
Several wind energy concepts utilize airborne systems that contain lighterthan-air gas, which supplements aerodynamic lift and expands these systems’ available operating regimes. While lighter-than-air systems can incorporate the traction and crosswind flight motions of their heavier-than-air counterparts, several lighterthan-air concepts have also been designed to deliver large amounts of power under completely stationary operation and remain aloft during periods of intermittent wind. This chapter provides an overview of the history of LTA airborne wind energy concepts, including the design drivers and principal design constraints. The focus then turns to the structural and aerodynamic design principles behind lighterthan air systems, along with fundamental flight dynamic principles that must be addressed. A prototype design developed by Altaeros Energies is examined as an example of the application of these principles. The chapter closes with suggestions for future research to enable commercially-viable LTA systems.
