Reviewer 2 Report
The paper is mainly developed in flight simulation environment. Following revisions are required:
- enhance the introduction, ie: explain better the UAV chosen, in particular specify its category wrt NATO UAV classification or similar.
- please specify better what is the real novelty of the paper (in the introduction and in the conclusions with related further works)
- in which environment is developed the 6DoF? please specify
- wrt Table4: time is SSM (seconds since midnight)? or starting from the simulation start?
- it is interesting to view also the timehistories of AoA and AoS during simulations. Or also maybe with some information on the mobile control surfaces during soaring.
- references need to be increased (please insert further technical paper on the UAV involved and others Journal Papers)

Dear Reviewer：
Point 1: Enhance the introduction, ie: explain better the UAV chosen, in particular specify its category wrt NATO UAV classification or similar.
Response 1: The introduction has been rewritten. The UAV better has the same dimensions as the albatross (mass around 10kg). According to the NATO UAV classification, the UAV mass under 20kg is classified as the mini UAV, Class I.
Point 2: Please specify better what is the real novelty of the paper (in the introduction and in the conclusions with related further works)
Response 2: The relative parts have been rewritten. The novelty of this paper is to give a new method for generating the dynamic soaring trajectory. Also, verify the feasibility of the trajectory method and the UAV dynamic soaring application. Finally, verify the energy harvesting mechanism model.
Point 3: In which environment is developed the 6DoF? please specify
Response 3: The environment is Matlab and Simulink.
Point 4: wrt Table4: time is SSM (seconds since midnight)? or starting from the simulation start?
Response 4: The time is starting from the simulation start. It is a misunderstanding because I wrote the table beader unclearly. The row is the initial status and final status. I have changed it.
Point 5: It is interesting to view also the timehistories of AoA and AoS during simulations. Or also maybe with some information on the mobile control surfaces during soaring.
Response 5: The change of AOA, AOS, and the control surfaces during the dynamic soaring have been added in the results part.
Point 6: references need to be increased (please insert further technical paper on the UAV involved and others Journal Papers)
Response 6: The introduction has been rewritten. The new references have been added in the introduction part.
Yours sincerely,
Wei Wang

Reviewer 3 Report
The manuscript carries the title of :"Modeling and Application of Dynamic Soaring by Unmanned Aerial Vehicle".
The topic of the paper is well presented with adequate drawings, pictures and graphs. So although it is a good manuscript two issues have to be addressed before being accepted for publication.
- The topic of the paper was already discussed in the literature. The authors should highlight the novelty of their paper over the existing knowledge in the literature.
- The authors present a numerical model without performing tests to verify their approach. The authors are asked to discuss this issue and clarify the reliability of their model. This is a crucial issue , which has to be clea

Response 2: The relative parts have been rewritten. I added a single case to verify the simulation program. It is detailed in the modeling part after the 6-DOF simulation program.
