Hybrid Airships (HAs) are being touted as an efficient aerial platform for various applications involving heavy cargo transportation, communications, scientific exploration, observation, and surveillance in the stratosphere. Hybrid airship technologies have developed significantly from mid-20th century onwards, and promise to offer unique operational advantages over conventional airships. The purpose of this review paper is to explore the concepts of hybrid airship designs that have been proposed in the recent past, and highlight the current state-of-the-art in this field. Major milestones in the development of hybrid airships are presented followed by the description of types of hybrid airships and their distinct features. This review paper focuses on dynastat type of hybrid airships, since they seem to be the most promising version of hybrid airships owing to the simplicity in their designs, and suitability for various civil and military applications. The characteristics of two types of dynastat, viz., winged-hull and multiple-hull are discussed in detail. The different aspects of the conceptual design and key disciplines including aerodynamics, dynamics, performance, thermal characteristics, structure, and optimization involved in the design of hybrid airships are reviewed in detail.

混合飞艇 (HA) 被吹捧为一种高效的空中平台，适用于涉及重型货物运输、通信、科学探索、观测和平流层监视的各种应用。从 20 世纪中叶开始，混合飞艇技术得到了显着发展，并有望提供优于传统飞艇的独特操作优势。本评论论文的目的是探讨最近提出的混合飞艇设计概念，并突出该领域当前的最新技术。介绍了混合飞艇发展的主要里程碑，然后描述了混合飞艇的类型及其独特的特征。这篇综述论文的重点是 dynastat 型混合飞艇，由于它们的设计简单，并且适用于各种民用和军用应用，它们似乎是最有前途的混合飞艇版本。详细讨论了翼壳型和多壳型两种动力型发电机的特点。详细回顾了概念设计的不同方面和混合飞艇设计中涉及的关键学科，包括空气动力学、动力学、性能、热特性、结构和优化。
