Limitations of this model include the lack of real sized geometry. Everything in this research is idealized to a scaled form, which could cause different results versus the possible real world results. We are also having a flow in only one direction over the stabilizer instead of any outside winds, such as a tail wind. These will not be measured in the wind tunnel, providing us with a limitation of the research.
Our results from this experiment could vary drastically. Because the rear stabilizer is not a lifting surface, which means that the rear stabilizer does not provide lift to the plane, merely stabilization. Lifting surfaces are the ones that provide the most drag in a system due to the increased forces caused lift. Because of this, there is the possibility that no drag, or minimal drag would be recovered from the implementation of a winglet on the rear spoiler. On the contrary, if we got a 1% fuel consumption savings in a Boeing 737, that would result in an increased range of 270 miles in flying distance.
For future research, we may have the possibility of determining a new rear stabilizer geometry which would reduce the entire airfoil drag. This could be done, or discovered, while using the flared winglet. Future research opportunities may exist due to our findings.
