This paper introduces a development of evaluation methods for flight performance of small unmanned aerial vehicle (UAV) in narrow space environments. Drone use in a narrow space is expected to provide many solutions for society, such as an inspection of plant equipment or house surveying after disaster and so on. While, in a narrow space, drone performance is restricted, for example, there are obstacles, GNSS (Global Navigation Satellite System) is denied, and it is difficult to discuss the performance of drone. Thus, the aim of the evaluation methods is to describe a drone flight performance in an easy-to-understand form, for industrial boosting. This paper explains the approach of our evaluation method and how to proceed with the development while incorporating opinions from drone users and providers. In addition, this paper describes prototypes of evaluation method for observation of obstacles, and a preliminary experiment to discuss the need of evaluation method for observation of obstacles for narrow space drone flight.

We develop test methods for Unmanned Aircraft System (UAS) mobility evaluation in a narrow space. This development aims to provide an easy-to-understand evaluation for people without technical knowledge, such as UAS users, and to boost the UAS industry. To indicate UAS performance in an easy-to-understand, the test methods in this research evaluate how much the UAS can do the task based on actually performing the test task in the test field. In addition, the test methods have variable environmental factors that dominate the task performance to discuss the UAS's environmental applicability for facilitating UAS usage scenario expansion. Because accepting the test methods for UAS users and manufacturers is essential for boosting the industry, this development is proceeding while discussing with UAS users and manufacturers. This paper introduces the development of a test method for evaluating UAS mobility for ascending through an aperture.

We develop UAS test method to evaluate its mobility capability in a narrow space. This research aims to provide an easy-to-understand evaluation of UAS environmental applicability for UAS boosting industry. This paper introduces an experiment to investigate the influence of UAS flight from a confined environment. In the experiment, we evaluate UAS mobility with 2 test filed, one open and the other confined, and compare these evaluation results. Through the experiment, we found that in a confined space, UAS makes a rocking motion and is attracted to walls when flying nearby the wall, and stable flight becomes difficult as a result.
