Let Let Let – Warplanes

SCAN 20

The Société des Constructions Aéronavales or SCAN was a small company based at La Rochelle. During the early war years a small all-metal flying boat trainer was designed by the SCAN constructor Bernard Devèze. Although the construction of this small flying boat, designated as the SCAN 20, took mainly place during the war years, the prototype made its first flight after the war on 6 October 1945. The SCAN 20 was a four-place trainer with an engine mounted on struts above the fuselage centre driving a 3-bladed pusher propeller. Further, it was fitted with a shoulder wing and a twin vertical tail arrangement. The French navy ordered a small batch of 23 production machines fitted with a Potez 8D30 engine of 450 hp. Operational history of the SCAN 20 is quite obscure and even the total number of aircraft actually built and delivered is unclear. More information is welcome!

S.N.C.A.S.E. SE-1200/SE-1210

After the SE-200.03 was completed and flown at the end of the war, Sud-Est engineers decided to design and build an even larger flying boat as the SE-1200. This type was a very large plane with a wing span of 61 metres and an all-up weight of 140 tonnes. In size and weight it was more or less equivalent with the British Saunders-Roe Princess. Power plants for the prototype were eight tandem-placed Arsenal 24H liquid-cooled engines of 4000 hp each in four engine nacelles driving contra-rotating propellers. The shoulder wing design was planned with wing floats that could be retracted at the wing tips. Production models were planned with eight Armstrong Siddeley Python turboprop engines, giving the plane an estimated cruising speed of 700 km/h. In 1947 a mock-up of the nose section was shown to reporters of the magazine The Aeroplane, but eventually the SE-1200 was never built.

However, a wooden 1/3 manned flying scale model fitted with four Renault engines was built and actually flown as the SE-1210; making its flight on June 1948 with the civil registration F-WEPI. Although the SE-1210 showed to have in general good handling characteristics, both in the air and on the water, flying was abandoned once the SE-1200 was cancelled and the aircraft was scrapped in 1953.
