这 德哈维兰 Dh.89 龙急流 is a 1930s short-haul biplane airliner developed and produced by British aircraft company de Havilland. Capable of accommodating 6–8 passengers, it proved an economical and durable craft, despite its relatively primitive plywood construction. Developed during the early 1930s, the Dragon Rapide was essentially a smaller, twin-engined version of the four-engined DH.86 Express, and shared a number of common features, such as its tapered wings, streamlined fairings and Gipsy Six engines. First named the “Dragon Six”, the type was marketed as “Dragon Rapide” and later simply known as the “Rapide”. Upon its introduction in summer 1934, it proved to be a popular aircraft with airlines and private civil operators alike, attaining considerable foreign sales in addition to its domestic use.

General Characteristics
The de Havilland DH.89 Dragon Rapide is a classic British twin-engine biplane airliner from the 1930s. Designed as a faster and more comfortable successor to the DH.84 Dragon, it proved to be a highly successful, economical, and durable short-haul transport aircraft despite its primary construction of wood (spruce and plywood) and fabric skin. Its popularity was immense, and during World War II, many were pressed into military service with the RAF and Royal Navy as the de Havilland Dominie, primarily for navigation training and light transport roles.
