Courbe puissance/couple

La courbe puissance/couple du moteur est établie suite à de nombreux tests realisés au niveau de la mer, à des conditions proches du standard ISA (International Standard Atmosphere = Standard d’Atmosphère International). La courbe suivante montre la puissance et le couple réels au vilebrequin de l’UL260iF, corrigés aux conditions ISA.

Puissance vs altitude-densité

Le graphique suivant montre la puissance disponible calculée du moteur UL260iF à différents régimes, WOT (wide open throttle = gaz grand ouvert) et altitude-density variable.


Dimension Weight
Maximum dimension in X direction (length)* 553 mm [21.77 inch]
Maximum dimension in Y direction (width)* 655 mm [25.75 inch]
Maximum dimension in Z direction (height)* 472 mm [18.6 inch]


  • Dry weight of the basic standard engine from serial production: 60,1 kg (132.5 lb)
