A<br />

NEW ELFE.-The designer of the<br />

. Elfe series. A. Markwalder, has made<br />

considerable modifications to the Standard<br />

Elfe. The wing area has been reduced<br />

by 5% by lessening the taper<br />

ratio to 0.4, thus i?creasing tbe aspect<br />

ratio 10 20; but owmg to new construction'<br />

methods the maximum wing loading<br />

is stj,j) only 25 kg./sq. m. (5.12 Ib.1<br />

sq. ft.). The elev/loor is raised to avoid<br />

the fuselage slipstream and ground damage.<br />

To maintain laminar flow over the<br />

front of the fuselage, its surface is COmpletelY<br />

unbroken and it slides forward<br />

as a who;le to allow the pilot to get in.<br />

An Open Class version, incorporating<br />

the same improvements, will have a<br />

span of 17.8 m. (58.4 ft.), an aspect<br />

ratio' ·of 23.3, and a wing loading of<br />

22.5 kg.; sq. m. (4,608 lb.;sq. ft.).<br />
