Overview
The Heinkel HD 21 was a trainer aircraft developed in Germany during the 1920s. It featured a traditional single-bay biplane configuration with staggered wings supported by N-shaped interplane struts. The fixed tailskid undercarriage had main wheels connected via a cross-axle. The cockpit arrangement included three open tandem seats, although one was often covered with a fairing. The HD 29, introduced in 1925, shared most characteristics but was designed exclusively as a two-seater.
One HD 21, bearing the registration SE-ACY, served as an air ambulance operated by Carl Gustaf von Rosen for the Red Cross during the Italian invasion of Abyssinia in 1935. Additionally, several units were utilized by the Reichswehr at the secret aviation training site located in Lipetsk.
