A production study on omithopters

Abstract

The authors have tried once to produce a dragonfly-type ornithopter using the power-type rubber, a flight could not be realized because of the difficulty in weight reduction. With recent advances in technology, ultra-compact and lightweight coreless motors, batteries, transmitter, receiver have been developed, now readily available. The authors, based on the results of previous studies, using parts that have been developed, we have attempted to make the production of a remote control ornithopter. This paper describes coreless motor with performance test results, design and production of a dragonfly-type and a butterfly-type ornithopter aiming to reduce the weight, and the current flight test results.
