Eduoard Joly and his son-in-law, Jean Delemontez, built their first Jodel, the D9 Bebe in 1948. It was the first in a line of variants from the single seat D9 to the 4 or 5 seat D140 Mousquetaire, each model retaining the classic Jodel shape. From any viewpoint, a Jodel can only be a Jodel.
The diminutive D9 was so successful that through their ‘Jodel’ company, the two men produced and sold plans. In 1950 they built on this success with a closed cockpit 2 seat design, the Dll.
The distinctive wing makes a Jodel, with its flat centre section and cranked up wing tips, instantly recognizable whether parked on the airfield or passing overhead. You may well have seen the slogan, ‘bent wings are best’ on everything from T shirts to car stickers, and for good reason. The design is a smart combination of strength and aerodynamic efficiency giving all Jodels a weight carrying and performance advantage over similar types.
“With lift comes drag. The Jodel outer sections with the dihedral have considerable washout. This means that at cruising speed the angle of attack, with its concomitant lift and drag is reduced, especially in the outer sections. At cruise speed you might oversimplify a bit and say the Jodel wing is flying on its centre section. Not only is the drag from the outer sections less but effective there is a higher wing loading on the centre section, which is now doing the lifting giving greater stability. However, slow the aircraft down and the angle of attack increases and the whole wing becomes effective. ” Peter Kraus
The Jodel range is still, after almost seventy years, popular with amateur builders around the world. These aeroplanes are loved for their forgiving flying characteristics, their carrying capacity, their short field capability and their economy.
