Design and development

The high performance Condor was financed by the Toulouse aero club Les Ailes (Wings) and designed by R. Castello for the use of J. Thomas, the director of the Black Mountain Regional Centre. [1]

It had a one piece, cantilever high wing, which was straight-edged and strongly tapered (taper ratio 0.37) to roughly semi-elliptical tips. It had a single spar structure with a leading edge torsion box. Long, narrow ailerons, divided into two parts, filled the entire trailing edge; these could also act as camber-changing flaps for low speed flight. [1]

The Condor's oval section fuselage was built around three longerons, two in the upper part and one, in the keel, which extended rearwards only as far as the rubber sprung landing skid, ending under the trailing edge. It was covered in stressed birch plywood. The forward fuselage was deep, with the wing on top and the single-seat cockpit ahead of the leading edge under a removable wooden cover with broad framed windows, limiting the pilot's view. Behind the wing the fuselage was slimmer and tapered to the tail, where a very small triangular fin carried a balanced rudder with an upright leading edge but which was full and rounded aft. The narrow tailplane, mounted forward of the rudder, carried balanced elevators. [1]

Operational history

The contemporary French journal Les Ailes first described the Condor in a June 1934 article that included images of the almost complete aircraft, [1] suggesting it first flew about that time, though one modern source dates the aircraft from 1933. [2] There is one modern report that the Condor crashed and was destroyed on its first flight, [3] though contemporary sources do not mention this event. A second example was constructed by the Aéro-club de l'Est at Nancy over the winter of 1934–1935; [4] they named it after one of their members, Jean Schmitt, who had died in a flying accident that spring. [5] One improvement was a cockpit canopy with increased window area and better visibility. [3] It remained active in the summer of 1937, flying from the nearby Plateau de Malzéville. [6] In early 1939 it joined the L'Espoir Aeronautique at Sarreguemines, who renamed it in memory of a local (Lorraine) pilot, Albert Martin. [7] It was active over the summer, [8] but was seized by the German forces when they invaded France in 1940. [3]
