Heinkel HD 28
Heinkel · German Reich · first flew 1927 · reconnaissance aircraft
The Heinkel HD 28 was a three-seat reconnaissance floatplane built by Heinkel as a pattern aircraft for Japan's Aichi company.
Recognition (WEFT)
| W — Wings | Mid-mounted, straight |
|---|---|
| E — Engines | 1 × piston, nose-mounted |
| F — Fuselage | Large ventral fin below a rudder that extends past the fuselage |
| T — Tail | Conventional |
WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- Three tandem cockpits with a rear gunner on a ring mount
- Large ventral fin below a rudder that extends past the fuselage
- Twin floats braced by multiple fuselage struts
Look for the large ventral fin extending below the fuselage line and the third, rearmost cockpit with its ring-mounted gun.
Specifications
- The Heinkel HD 28 has a length of 11 m (36 ft).
- It has a wingspan of 15 m (49 ft).
- Its maximum speed is 198 km/h (123 mph).
- Typical crew: 3.
Figures are for the representative variant described above; marks differ. See how AircraftIQ sources figures.
History
A single-bay biplane with equal-span, unstaggered wings and a distinctive deep ventral fin, the HD 28 carried three crew including a rear gunner on a ring mount, powered by a Lorraine-Dietrich engine. Supplied to Aichi as the basis for what became the Aichi Experimental Three-seat Reconnaissance Seaplane, it was ultimately rejected for Japanese production over engine problems and excess weight.
Variants
Aichi's derivative attempt did not enter production; only the single Heinkel-built pattern aircraft was completed.
Where you'll see it
As a rejected pattern aircraft, no HD 28 survives today.
