Images and descriptions of Dunne's aircraft appear from time to time. They are often mis-identified by researchers who do not know their full history. Here are some of the key design points which will help you to identify which machine you are really looking at.
| Designation | Description | Where | When | Recognition points |
|---|---|---|---|---|
| Dunne-Huntington | Triplane | Eastchurch | 1910-14 | Triple-tandem wing. Initially inline engine with twin propellers, angled elevon hinges, interplane side curtains. Later rotary with one propeller, straight hinges, no curtains. |
| D.1A | Biplane glider | Blair Atholl | 1907 | Separate launching trolley. Dark fabric with white stripes. No wingtip fins. No fuselage. |
| D.1B | Powered D.1 biplane | Blair Atholl | 1907 | D.1A mounted on open-frame power chassis, twin propellers. Separate launching trolley. Never flew. No known photographs. |
| D.2 | Triplane | [Farnborough] | 1907/8 | Glider. Triple-tandem wing. Unbuilt design. |
| D.3 | Biplane | Blair Atholl | 1908 | Glider. No fuselage. No known photographs. |
| D.4 | Biplane | Farnborough, Blair Atholl, Shellbeach | 1908, 1909 | Twin propellers, model no. on wingtip fin, dark fabric with white stripes. Hopped. |
| D.5 | Biplane | Shellbeach, Eastchurch | 1910 | Single square cut-out to fin, twin propellers, inline engine. Crashed. |
| D.6 | "Dunne-Capper" monoplane | Larkhill (Salisbury Plain) | 1910-11 | Triple A-frame open chassis, inline engine. Never flew. |
| D.7 | Monoplane | Eastchurch, Larkhill | 1911-13 | Rectangular open chassis, inline engine with overwing radiator or rotary engine with 2-bladed prope and torque flap. Several examples built, 1st was D.6 rebuilt, all crashed. [Often confused with the D.6] |
| D.7bis | French-built monoplane | Villacoublay (Paris) | 1913 | 2-seat open chassis, rotary with 4-bladed prop, rectangular elevon braces. Seen only in France (other monoplanes only in UK). |
| D.8 | "Carden's" biplane | Eastchurch, Larkhill | 1911-12 | Single square cut-out to fin, single propeller, inline engine. |
| D.8 | "Nieuport-Dunne" biplane | Eastchurch, France | 1913 | Single square cut-out to fin, single propeller, rotary engine. Carden's machine reworked. |
| Nieuport | "Nieuport-Dunne" biplane | France | 1913-14 | License-built. Fins inset with curved trailing edge. Rotary with single propeller. Trailing main wheels. Derived from D.8. Not known to have flown. |
| D.8bis | "Hendon" biplane | Hendon | 1913 | Twin triangular cut-outs to fin, single propeller, rotary engine. Reduced leading-edge droop, giving nose-up attitude in flight. |
| D.8bis | "Farnborough" biplane | Eastchurch, Farnborough | 1913-14 | Twin triangular cut-outs to fin, single propeller, rotary engine. Full leading-edge droop. Eventually given serial no. 366. |
| D.8bis | Undelivered biplane | Eastchurch | 1914 | Twin triangular cut-outs to fin, single propeller, rotary engine. Full leading-edge droop. Cancelled 2nd Farnborough machine. |
| D.9 | Biplane | [Eastchurch] | 1913 | Unequal span (sesquiplane). Unbuilt design. [Often confused with the very different Levis-Belmont, aka, "James", aka "Leonie" monoplane] |
| D.10 | Biplane | Eastchurch | 1913 | Failed experiment. No known photographs. [Often confused with the D.8 bis] |
| D.11 | "Armstrong Whitworth" biplane | [Scotswood (Elswick)] | 1914 | Unfinished design. |
