This revised paper can be accepted now.

This manuscript is a resubmission of an earlier submission. The following is a list of the peer review reports and author responses from that submission.

Round 1

Reviewer 1 Report

This paper investigates an intrinsically safe drone's propulsion system and the potential approaches to enhance efficiency and mitigate the heat. The study begins with the drone’s sizing approach before moving on to the experimental setup utilized to test the drone’s propulsion system. This paper’s topic is interesting, but there are many aspects that need to be improved and depended on its present status:

1. The limitations (research gap of the existing literature) and contributions of this study should be summarized at the end of the Introduction section.

2. The model should be presented as a separate section to describe, rather than being placed in the problem flow diagram.

3. The solution method should be described as an independent chapter to reflect the scalability of the research method.

4. The conclusion section should also be further improved to illustrate the practical significance of the study.

5. The reference “Truck–drone hybrid routing problem with time-dependent road travel time” about solving to truck-drone routing problem should be added into the references.

 

Therefore, I think that this paper should be further improved, especially in the scientific and high-quality paper structure design.

Reviewer 2 Report

Flow of literature should be improved.

Section 3: Propulsion System Performance Measurement Setup should be explored in complete details.
