Avions Borel

Hi,

the Borel company or SICM designed a transport triplane aircraft project in 1922,does
anyone hear about it ?.

Hi Hesham,

It was SGCIM for Société Générale des Constructions Industrielles et Mécaniques ;
Plant was at Puteaux (Paris suburbs), like Morane-Saulnier, with offices in Paris.

Never heard about a triplane, but could not it be a 3-engined transport monoplane ?

May be that's right Marc-91,

but do you have a drawing or more info about that 3-engined transport aircraft ?.

In addition to the complete machine Borel shows a scale model of a huge three-engined passenger machine — a cantilever monoplane, [.../...] The commercial machine (monoplane) is to be fitted with three Lorraine engines of 375 h.p. each, and is designed to carry 30 passengers Inside the centre-section of the very thick monoplane wing. It will have a total weight of 22,000 lbs. and a radius of action of 620 miles with full load. The span is 36 ms. (118 ft.) and the total wing area 240 sq. ms. (2,582 sq. ft.). According to wind tunnel tests at St. Cyr, the machine should have a speed near the ground of 202 kms. (125 miles) per hour. With the central engine stopped the estimated speed is 174 kms (108 miles) per hour. Thus if the full-size machine comes up to the model figures, the power expenditure is only 3 7 5 h.p. per paying passenger. Asked whether the machine would fly with one of the wing engines stopped, the gentleman in charge appeared to think this doubtful.

Thank you Mrac-91;

and this Borel flying boat project,I found it in NASA report,and my dear Vigair said;
it was mentioned in Trait d'Union issue 202.

Hi,

here is the Borel three engined blended-wing medium transport aircraft,fitted with fixed
landing gear,project of 1924.
