JANUARY !S, 1923 21S -AEBO •SHOW-1922 By THE TECHNICAL EDITOR (Continued from page 22) S. I. A. LATECOERE, Toulouse ONLY one machine was exhibited this year bySocieti Industrielle d' Aviation Latecoere, but what the exhibit lacked in numbers it made up forin size. The Latecoere " L.A.T.6 " is a huge four-cngined bomber, with the 260 h.p. Salmsonengines placed in tandem on the wings. The fuselage of this machine was exhibited at the1921 Paris Show, when both its design and construction came in for considerable criticismNor is it probable that the critics, after seeing the finished machine, will have changed theirviews. To begin with, the tandem arrangement of engines has been found years ago to be badaerodynamically, owing mainly to the fact that the airscrew of the rear engine is working inthe slip stream from the tractor, and conse- quently has to have a greater pitch, as it isworking in air of greater velocity. Secondly, the many projections on the machine must havea very adverse effect upon the efficiency, although if the advantages aimed at areattained, this price might not be considered unduly great. In the " L.A.T.6 " the reasonshave obviously been to provide gun platforms in positions where there was a good field offire, so as to enable the machine to be inde- pendent of escorts for fighting off attackers. THE LATECOERE L.A.T.6 : This photograph of the fuselage wastaken at the 1921 Paris Show, and shows the peculiar construction. The undercarriage has been entirely re-designed since then.
