Dunne D.7
type of aircraft
The Dunne D.7 was one of J. W. Dunne's swept wing tailless aircraft designed to have automatic stability, first flying in 1911. It was a single seat, single engined pusher monoplane developed from the unsuccessful D.6.
Design and development
Although J. W. Dunne is best known for his inherently stable tailless biplanes such as the D.8, he also developed a series of inherently stable monoplanes. He first submitted a monoplane design to the War Office when he joined the Army Balloon Factory at Farnborough in 1906, but they told him to build a biplane instead.
D.6
It wasn't until Dunne left the Balloon Factory and started his own company, the Blair Atholl Aeroplane Syndicate Ltd., that a monoplane could be built. The D.6 was built by Dunne's old commanding officer, Col. J. E. Capper who was also a member of his Blair Atholl Aeroplane Syndicate. It was finished in 1911, with a 60 hp (45 kW) Green in a pusher configuration. Three A-frames supported the wing engine, pilot and undercarriage. The wing was straight edged, tapering from a central chord of 6 ft 3 in (1.91 m) to 5 ft 0 in (1.52 m) at the tips.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Dunne D.7”, the useful work is to connect “type of aircraft” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Nov 8, 2025. The linked authority identifier is Q5315572. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1911 and 1906.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
