Wing Transmission for a Micromechanical Flying Insect
Flapping wings provide unmatched maneuverability for flying micro-robots. Recent advances in modelling insect aerodynamics show that adequate wing rotation at the end of the stroke is essential for generating adequate flight forces. We developed a thorax structure using four bar frames combined with an extensible fan-fold wing to provide adequate wing stroke and rotation. Flow measurements on a...
متن کاملTowards High Efficiency Hypersonic Flight – Hypersonic Bi-Directional Flying Wing
This paper examines the use of a hypersonic bi-directional flying wing concept for use in a high efficiency hypersonic system. The bi-directional flying wing concept consists of a symmetric planform which enables flight to occur at two different geometric configurations. The subsonic configuration would have a high aspect ratio and a low sweep. The aircraft would then rotate 90 degrees and ente...
متن کاملFlying Wing versus Conventional Transport Airplane: the 300 Seat Case
Unconventional aircraft are being studied by the aeronautical engineering community with accelerated interest and effort to improve economic efficiency and to overcome operational and infrastructure-related problems associated to the increasing size of transport airplanes. The objective of the research reported here is to assess the technical feasibility and operational efficiency of a medium s...
متن کاملAntennal mechanosensory neurons mediate wing motor reflexes in flying Drosophila.
Although many behavioral studies have shown the importance of antennal mechanosensation in various aspects of insect flight control, the identities of the mechanosensory neurons responsible for these functions are still unknown. One candidate is the Johnston's organ (JO) neurons that are located in the second antennal segment and detect phasic and tonic rotations of the third antennal segment r...
متن کاملTowards flapping Wing Control for a Micromechanical Flying Insect
A 2 DOF resonant thorax structure has been designed and fabricated for the MFI project. Miniature piezoelectric PZN-PT unimorph actuators were fabricated and used to drive a four-bar transmission mechanism. The current thorax design utilizes two actuated four-bars and a spherical joint to drive a rigid wing. Rotationally compliant flexure joints have been tested with lifetimes over 10 cycles. W...
