The Heinkel HD 32 was a
trainer developed in
Germany in the 1920s, a derivative of the
HD 21. Like that aircraft, it was a conventional,
single-baybiplane, but had only two
cockpits rather than the three that the HD 21 had. The other significant change was the use of a Siemens
radial engine in place of the inline units that powered most of the HD 21 family.
