Soaring strategy investigation of cinereous vulture (Aegypius monachus) by sailplane
(Indian Counc Agricultural Res, 2020)Soaring has great importance to large and heavy terrestrial birds because they can gain altitude without using power in this way. The cinereous vultures were near threatened species in the world, so it was hard to observe ... -
Theoretical model proposal on direct calculation of wetted area and maximum lift-to-drag ratio
(Emerald Group Publishing Ltd., 2021)Purpose As measuring flight performance by experimental methods requires a lot of effort and cost, theoretical models can bring new perspectives to aircraft design. This paper aims to propose a model on the direct calculation ... -
A key design parameter proposal for aerodynamically efficient subsonic blended wing body
(Emerald Group Publishing Ltd., 2021)Purpose Blended wing body (BWB) is a very advantageous design in terms of low fuel consumption, low emission and low noise levels. Because of these advantages, the BWB is a candidate to become the commercial passenger ... -
Is there any aerodynamic obstacle to gliding in great bustard?
(Inst Zoology, 2021)Gliding and soaring are important flight styles, which reduce the energy consumption of birds. Most of the migratory birds and raptors take advantage of these flight styles in order to stay in the air much longer. However, ... -
Designing and producing a bird-inspired unmanned sailplane
(Emerald Group Publishing Ltd., 2021)Purpose – Increasing endurance was a very appropriate subject for the biomimetic approach. The study aims to design and manufacture a longlasting mini unmanned aerial vehicle (UAV) using active gliding and soaring. Desi ... -
