“…When these are considered, the percentage of computational model articles is approximately half of the total number of aerodynamics articles (50%). A few articles (9%) specifically examine the aerodynamic effects of flapping wings on propulsive performance (e.g., lift, thrust, and drag) (Mueller et al, 2010 [35], Mahardika et al, 2011 [36]).…”

Biomimetic air vehicles (BAV) are a class of unmanned aircraft that mimic the flapping wing kinematics of flying organisms (e.g. birds, bats, and insects). Research into BAV has rapidly expanded over the last 30 years. In this paper, we present a comprehensive bibliometric review of engineering and biology journal articles that were published on this subject between 1984 and 2014. These articles are organized into five topical categories: aerodynamics, guidance and control, mechanisms, structures and materials, and system design. All of the articles are compartmented into one of these categories based on their primary focus. Several aspects of these articles are examined: publication year, number of citations, journal, authoring organization and country, non-academic funding sources, and the flying organism focused upon for bio-mimicry. This review provides useful information on the state of the art of BAV research and insight on potential future directions. Our intention is that this will serve as a resource for those already engaged in BAV research and enable insight that promotes further research interest.

The aim of current research work on micro air vehicles is to realize their autonomous control, i.e. building a library for a lookup table that would apply to micro electronics. In doing so, comprehensive flight tests need to be carried out. In this study, a four-wing flapping MAV is built and a multi-discipline approach is used to design the MAV model. Precision manufacturing technology is introduced here. The finished micro air vehicle has a weight of 8 g and is tested for flight by remote control. The micro air vehicle can perform both hovering and forward flight with high maneuverability. Forward flight is investigated first in this paper. Particle image velocimetry system is employed to examine unsteady aerodynamic performance in selected flight conditions. The study reveals that the micro air vehicle model will provide enough lift at a 30 angle of attack and flapping frequency of 12 Hz, which is consistent with real-life forward flight observations.

“…Robobee [10] a bee mimicking real insect size MAV, on the other hand, uses an even more simple flapping mechanism utilizing piezoelectric actuators and a passive pitching mechanism, but demonstrates high flight stability through sophisticated control of the individual wings. Another study evaluated the effect of outer wing separation on lift and thrust generation in a flapping wing system that closely mimics the feather separation of birds during slow forward flight and hovering, demonstrating improved lift and thrust force generation [11]. These examples show that weight constraints, energy efficiency and robustness of a MAV demands simplicity that can be achieved through creatively implementing techniques learnt from nature.…”

-In this paper, aerodynamic characterization and performance analysis of a bioinspired multilayer flexible wing are discussed. Our membrane wing that consists of two separate layers can achieve better performance for applications utilizing flapping wing locomotion. This novel wing has two distinct features, the first, a passive shape deformation that is dependent on the direction of the aerodynamic loading on the wing surface, thus can reduce the negative lift of the upstroking wing without a complex mechanism required for active pitching. The other feature is the vortex trap mechanism realized by the separation of the layers at upstroke that results in a large scale vortex above the upstroking wing. This vortex can also generate additional lift by preserving a low pressure core. These features are inspired by the active wing shape control of birds, as well as an unsteady aerodynamic mechanism called clap and fling exhibited by several flying insect species. Such passive shape control on membrane wings could be utilized on micro air vehicles featuring a simple flapping mechanism design to achieve robustness and light weight.
