Design and development

The SE-2100 was designed by Pierre Satre,[1][2] later the chief designer of the Concorde,^{[citation needed]} as a response to a 1943 specification by the Vichy French Air Ministry for a two-seat touring aircraft.[2] An all-metal aircraft, it had a low, cantilever, straight tapered wing with 55° of sweep on the leading edge and 10.43° of dihedral. There were fixed leading edge slots and trailing edge ailerons but no conventional flaps. The wing tips carried large, rounded fins with rudder-like rear portions which only moved outwards; they were used differentially for yaw control and jointly as flaps.[3]

The SE-2010 had a short, blunt-nosed nacelle-type fuselage with a cabin which could be configured to seat one centrally or two in side-by-side, dual control configuration. The seats were just aft of the leading edge, with a baggage compartment behind them. Access was via deep, wide, forward hinged doors on both sides; to make this possible, a piece of the wing root leading edge was an integral part of each door. A 140 hp (104 kW) Renault Bengali 4 four cylinder, inverted, inline engine was mounted in pusher configuration behind the cabin and air-cooled via a ventral scoop; it drove a two-blade propeller positioned just behind the trailing edge. The SE-2100's fixed, tricycle undercarriage had pneumatic shock absorbers and mainwheel brakes; the nosewheel was free-swivelling.[3] At different times the undercarriage legs and wheels were unfaired or faired.[1]

The SE-2010 flew for the first time on 4 October 1945.[4] Despite demonstrating promising performance[5] and showing high manoeuvrability when demonstrated at the 1946 Paris Air Show,[6] no production followed, with the prototype surviving into the early 1950s.[7]
