The material of this article is for informational purposes and is based on data from the profile aerodynamics analysis program. The interpretation of the data is subjective and may not be accurate.
When fine-tuning the boomerang, the aerodynamic profile should be modified gradually, making small changes at a time. This will allow you to see what kind of result this or that change brings. To check the changes, you should make several runs, with different parameters, to make sure of the result.
Let's consider some modifications that change the characteristics of the boomerang wing. You can get acquainted with the terms in this article.
Cutting the leading edge
This technique is often used to increase the lift at the end of the wing.
The upgraded (W031_m) lower edge cut is made flatter and longer in comparison with the original (W031) version.
The graph shows the increase in lifting force (Cl) at the profile W031_m.
Recess in the plane of the wing
This modification increases the efficiency of the wing.
Such a deepening is more difficult to implement, but it allows you to increase the lifting force, practically without sacrificing drag.
The drag increases slightly.
