Abstract

This paper suggests a new method to estimate the roll and pitch damping moment coefficients of a flying disc through sensor data from the onboard IMU module. This method can be easily performed than wind tunnel or computational fluid dynamics methods because it estimates aerodynamic coefficients simply after accumulating the inertial data through several repeated flight experiments. Estimated coefficients are applied to a simulator which is based on the flight dynamics of a flying disc. Finally, the predicted flight trajectory is compared with the true position provided by GPS, which demonstrated the validity of the proposed estimation method.

본 논문은 플라잉디스크에 탑재된 계측모듈의 IMU 데이터를 이용하여 롤링 및 피칭모멘트 감쇠미계수를 추정하는 방식을 새롭게 제시한다. 제안한 방식은 반복된 수 회의 원반 비행 실험을 수행하여 데이터를 구축한 뒤 공력 계수를 추정하므로, 풍동이나 전산유체해석을 이용하는 방법에 비해 수월한 실험적 대안이 될 수 있다. 추정한 공력 계수는 플라잉디스크의 비행동역학 모델을 토대로 구현한 시뮬레이터에 적용하여 비행 궤적을 예측하는 것에 이용되었으며, 이를 GPS의 위치 궤적과 비교함으로써 성능을 검증하였다.
