MHA tasarımlarına ilham veren kanatlı böceklerin uçuş özellikleri

In the last years, there has been lots of investigation on the aerodynamics of flapping wing micro air vehicles. By analysing the flapping mechanics of natural flyers like birds and insects, human made robotical unmanned aircrafts are manufactured. In general, the works which investigates the flows at low Reynolds numbers covers both the biological flyers and human-made Micro Air Vehicles (MAV). In this work, the flight and properties of winged insects are summarized for the purpose of giving inspiration for the designs of Micro Air Vehicles. In addition, dimensional analysis which could be used for the experimental works is shown.

The main aim of this study is to accurately model the wing of a hawkmoth (Manduca sexta) to implement it in a flapping wing mechanism for a micro aerial vehicle (MAV). The wing is first modeled in ANSYS/SpaceClaim then the model is verified by performing modal analysis on the finite element model (FEM) of the wing in ANSYS/Mechanical. Grid refinement study is performed on the FEM. Results of the modal analysis of the modeled wing are compared to literature results and it is seen that both results are ...
Effect of ground on flow structure of non-slender delta and reverse delta wings
Koçak, Göktuğ; Yavuz, Mehmet Metin; Department of Mechanical Engineering (2023-1-26)
Flight condition of aircrafts proximity to the ground, so-called “Ground Effect” (GE), is among one of the most recent research areas since the aerodynamic performance and stability of wing in ground effect (WIG) crafts significantly vary due to the flow dynamics associated with the interaction between the wing and the surface. In the present study, ground effect of non-slender delta wings (DW) and reversed delta wings (RDW) at static ground effect (SGE) condition in the absence of heave and pitch motion w...
Birlikte Sarkan Yük Taşıyan Kol Uçuşundaki Quadrotorların Modellemesi ve Kontrolü
Tekinalp, Ozan(2016)
Insansız hava araçlarının (IHA) kol uçusu bazı avantajları nedeniyle gittikçe daha çok önemkazanmaktadır. Örnegin afetlerde arama sırasında kol uçusu yapan insansız hava araçları iledaha genis bir alanın daha kısa sürede aranması mümkün olabilir. Yine göçmen kuslar gibibirbirini takip ederek öndeki aracın dümen suyunda (wake) uçan insansız hava araçlarındayakıt tüketiminin daha az olacagı da bilinmektedir. Diger yandan kol uçusu ile tek basınayapılamayacak görevlerin yerine getirilebilmesi mümkündür. Bunlar...
Winglet design and analysis for low altitude solar powered UAV
Gölcük, Ali İhsan; Kurtuluş, Dilek Funda; Department of Aerospace Engineering (2016)
To improve the aerodynamic performance of aircraft, comprehensive studies have been carried out in different areas such as wing optimization, tail types and fuselage shape, etc… One of the most important factors affecting the aerodynamic performance of the aircraft is lift induced drag caused by wingtip vortices. Winglet is a device referred as a small, vertical and angled extension attached at aircraft wingtip. It is used to minimize strength of vortices and reduce the lift induced drag. Various types of w...
Control of flow structure on 70° swept delta wing with along-the-core blowing using numerical modeling
Küçükyılmaz, İbrahim Can; Yavuz, Mehmet Metin; Department of Mechanical Engineering (2016)
In recent years, interest has increased in Unmanned Combat Air Vehicles (UCAVs) and Unmanned Air Vehicles (UAVs), which can be represented by simplified planforms including delta wings. Delta wings experience the formation of two counter-rotating vortices on the leeward side of the planform due to the shear layer separated from the windward side. At sufficiently high angle of attack, these vortices undergo sudden expansion, called vortex breakdown/burst, which is quite detrimental considering the aerodynami...
