The D.31 was Roger Druine's second post-war design following the Aigle and was intended for both production and home-build markets. Production build rights for the low-wing monoplane were acquired by Rollason Aircraft and Engine in the UK and Stark Flugzeugbau in
Germany, and both companies produced modest quantities to add to those home-built versions. Many examples remain extant.

| sven, 05.11.2009 Several Turbulents were built with better streamlined cowlings and canopies. In this form some were able to exeed vne in level flight. Unique? G-APWP
Built by Handley Page aircraft engineer Colin Rogers reached 135mph in level flight.untill the advent of formual V racing this made it the fastest Volksvagen powered aircraft .The 1200cc Poleman Hepu converted engine featured chrome plated cylinder barrels from the Porsche 356 racing engine.Cowlings that extended along the fuselage and a spring steel undercarriage mounted on the fuselage
With wheel spats added to the aerodynamic efficiency.Oddly an engineers wire brush served as a tail skid.
Originally it was housed in a fairing but a day at Elstrees tarmac runway destroyed it, from then on it was fitted complete with convenient handle but no fairing. | | Eduardo Sosa, chepososa(@)hotmail.com, 04.11.2009 where could we get one?? |
