Reviewer 2 Report
In this paper, the authors present an experimental study in a wind tunnel to study the mechanism of oscillating jet flow control. The paper is well-written and the overall direction is acceptable. However, the quality of the paper can be improved and requires some revisions.
1. Is there a specific reason that the authors used a double-feedback fluidic oscillator? It would be great if the authors could explain different types of fluidic oscillators in 1 paragraph and then, explain why they selected this specific geometry.
2. for "2.1. Actuator Structure and Vertical Tail Model Design" if authors used the dimensions of a patent or previously published paper, please refer to it or explain why such dimensions are selected like 50 degrees of divergence and etc. it would enhance the quality of the experimental description of this section.
3. Regarding the Schlieren visualization in the introduction (line 55), there are other latest references such as "https://doi.org/10.1063/5.0076544" that authors could refer it.
4. Regarding line 49, and other applications of oscillating jet, authors could refer to "https://doi.org/10.3390/app10238668" which is published in applied science journal in 2020 or "https://doi.org/10.1016/j.ijheatfluidflow.2020.108701" or "https://doi.org/10.1016/j.ijheatmasstransfer.2021.121208" for heat transfer enhancement.
Reviewer 3 Report
I liked the work, I recommend the material for publication. In experiments, variations in the aerodynamic and flow characteristics of the vertical tail were studied. The characteristics of the flow field were determined under typical conditions of a scale model of the vertical tail unit. Both the characteristics of the vertical tail and the flow around without control with the influence of various parameters were studied. The flow control law and the effect of vertical tail control when using oscillatory-jet control were considered, which was generalized by studying the surface topology, the spatial distribution of the flow field, and the pressure characteristics of the rudder. But there are a couple of points that I advise the authors to pay attention to:
- It is necessary to work on the English language, there are errors and typos in the text;
- The material has some gaps, for example, line 480;
- Reference list needs to be revised.

Round 2
Reviewer 1 Report
The revised manuscript has been significantly improved compared to the original one. Various relevant explanations have been added about the experimental methods as well as the quantification of the results. Accordingly, the manuscript is now clearer and more convincing. Therefore, the reviewer thinks the manuscript can be accepted for the publication.
