  • The paper presents the design, development and testing activities of the multi-rotorcraft-based unmanned aerial vehicle at the Center for Unmanned System Studies, Institut Teknologi Bandung (ITB), Indonesia. The multi-rotor system was selected as the design stepping stone for future development of personal aerial vehicle prototypes. A step-by-step design program is conducted to study the technology building blocks and critical issues associated with the design, development and operation of personal aerial vehicles. A number of multi-rotor configurations have been investigated providing basic guidelines for developing a stable unmanned aerial platform. The benefit of the presently selected configuration is highlighted and some preliminary testing results are presented.

  • In modern society, the use of small rotary-wing unmanned aerial vehicles such as drones is increasing. As the military considers tactics using drones, demand for drones is increasing. However, there is still no airworthiness certification standard for drones for safety. In this paper, we proposed airworthiness certification standards for small rotorcraft unmanned aerial vehicles based on CS-LURS in Europe and STANG-4703, 4738 (draft) of the North Atlantic Treaty Organization. In addition, airworthiness certification standards have been strengthened through the case of unmanned aerial vehicle accidents in operation by the Korean military. The airworthiness certification standards for small rotary-wing unmanned aerial vehicles will be supplemented through a demonstration project.

  • 근거리 감시정찰을 수행할 수 있는 헬리콥터형 무인항공기를 개발하였다. 임무수행 가능성을 검토한 결과 전동 모터로 구동되는 동축반전 헬리콥터형 비행체가 선정되었다. 자동비행을 위해 상용 자동비행장치와 무선통신 모뎀이 채택되었고, 공중촬영을 위한 CCD 카메라가 탑재되었다. 완성된 비행체는 수동 비행시험을 통해 성능을 검증하였으며, 자동비행장치 탑재 후 점항법 비행을 통해 임무수행이 가능함을 확인하였다. 본 논문에서는 동축반전 무인항공기의 개발을 위한 설계 및 체계종합 전 과정에 관하여 기술하였다.

  • This paper presents the conceptual design of a multi-rotor unmanned aerial vehicle (UAV) based on an axiomatic design. In most aerial vehicle design approaches, design configurations are affected by past and current design tendencies as well as an engineer's preferences. In order to design a systematic design framework and provide fruitful design configurations for a new type of rotorcraft, the axiomatic design theory is applied to the conceptual design process. Axiomatic design is a design methodology of a system that uses two design axioms by applying matrix methods to systematically analyze the transformation of customer needs into functional requirements (FRs), design parameters (DPs), and process variables. This paper deals with two conceptual rotary wing UAV designs, and the evaluations of tri-rotor and quad-rotor UAVs with proposed axiomatic approach. In this design methodology, design configurations are mainly affected by the selection of FRs, constraints, and DPs.

  • 모형헬리콥터를 이용한 무인항공기 설계를 위해 비선형 형태의 수학적 모델이 선행되어야 한다. 모형헬리콥터는 실기 헬리콥터에 비해 회전수가 훨씬 높으며 따라서 동특성도 실물기에 비해 훨씬 빠르다는 차이점이 있다. 본 논문에서는 축소형 헬리콥터의 수학적 모델링에 필요한 정식화과정으로서 복잡성을 최소화하면서도 실제의 동특성에 잘 부합하도록 각 구성요소별로 계산한 후 전체로 합산하는 방법을 제시하였다. 제자리 비행과 전진비행에서 수치계산을 통해 트림 값들을 계산하고 제자리 비행조건에서 선형 시스템을 해석하여 모형헬리콥터의 비행모드를 분석하였다. 계산결과 일반적인 경향은 몇 가지 작은 부분 이외에는 대체로 다른 연구결과와 비슷하였다. 이 과정을 검증하기 위해서 비행시험을 수행하여 시스템식별에 의한 결과와 비교하는 연구가 후속 수행될 예정이다.
