Sud-Est SE-2300 / SE-2310 / SE-2311
Pierre Satre began the SE-2300 design during World War II as a conventionally laid out, all metal, two seat, single engine cantilever monoplane, with tapered low wings having 4° of dihedral built around inverted U-section main and auxiliary spars. The wings had a centre section integral with the fuselage and two outer panels, all covered with electrically welded skin. There were plain flaps, with a maximum deflection of 40°.
The fuselage of the SE-2300 was constructed from four pre-formed panels welded together. A 140 hp (104 kW) Renault Bengali 4 four cylinder, inverted, air-cooled inline engine, fed from a fuselage tank, drove a two blade propeller. The over-wing cabin seated two side-by-side with dual controls. Behind these seats was space for a third (optional in the SE-2300 and standard in the SE-2310 variant) and baggage. There were access doors and rear view transparencies on both sides. At the rear, the tailplane was mounted at mid-fuselage and the fin and deep rudder were straight tapered except near the keel and almost triangular above the fuselage.
The first and only SE-2300 first flew on 26 October 1945 and had a fixed conventional undercarriage with oleo-pneumatic springing, faired main legs and wheels and a swivelling tailwheel. The two SE-2310s had tricycle undercarriages, the first unfaired but the second with faired legs and spats.
With a four seat version, the SE-2311 under development but unbuilt, the three seat SE-3010 was entered into a 1946 French Transport Ministry contest for a four seat tourist aircraft in February 1946. It was not successful, the award going to the Nord 1200 Norécrin and development of the SE-2300 series was abandoned. The last example remained in use until at least 1956 as a company hack.
