Ich habe mal versucht im Internet etwas darüber zu finden. Here is something in english:
The Oswald efficiency factor, e , accounts for the fact that, because aircraft design is a compromise, no wing or airplane is as efficient as is theoretically possible.
The theoretical maximum value for the Oswald efficiency factor is one.
The smaller the value of e the less efficient the aircraft.
The Oswald efficiency factor affects the effective induced power required, i.e., the power required associated with the production of lift.
Typical values for light aircraft are from 0.5 to 0.8.
Based on flight test results, the Bonanza, with gear and flaps up, i.e., clean, has an Oswald efficiency factor of approximately 0.56 to 0.65.
Extending the gear and/or flaps has some effect but not a large one on the value of e

Den, wie ich denke wichtigsten Satz, habe ich mal markiert. Wenn jemand in der Lage ist, diesen Satz verständlich und sinngemäß ins Deutsche zu übersetzen, dann möge er das tun. Ich habe mich nicht getraut
Der Rest ist ja sonst eigentlich verständlich.
