Delta wing has numerous applications across aerospace vehicles. Highly inclined and variable swept back wings have a lot of added advantages in maneuverable fighter airplanes, supersonic cruise airliner; and modern unmanned aerial vehicles that have been equipped with and have deployed low swept back delta wings. Vortex flow across these delta wings is dominant for micro aerial vehicles and mini unmanned aerial vehicles flying at a low speed Reynolds number regime. Many experiments were carried out to study and analyze the aerodynamic flow parameters of delta wings wherein vortex sheet flow patterns were observed and studied at different angles of attack and flow parameters. In this paper we are plotting lift co-efficient and drag coefficient for a flat delta wing with and without winglets at different angles of attack under low Reynolds numbers. Furthermore, simulations are carried out to draw comparisons between the winglets on the basis of span-wise flow velocity vectors.

“…The positive camber exhibited by the bird was primarily the reason behind this asymmetrical distribution in lift generation and also its inability to reverse during the up-stroke. The airfoil of a hummingbird also acts as a dynamic stalling airfoil [26] [1]. For the purpose of extraction of the involved wing kinematics, anatomical landmarks are located in the form of proximal plane and the distal planes on the primary feathers as well as the secondary ones.…”

“…During soaring, birds either extract energy from the shear wind field for dynamic soaring or from thermals for thermal soaring. Hence it depends on the incident airspeed or the birds' speed and also their genetic encoding [1]. The traits of an eagle wherein it soars for free, its wing morphing techniques, its slotted wingtips, and its efficient control surfaces that can perform roll and yaw operations with simple actuations; can help create energy-efficient Unmanned Aerial Vehicles (UAVs) with optimum aerodynamic traits.…”

This review tends to shed light on the eagle’s aerodynamic attributes along with its inbuilt structural control surfaces that facilitate its high maneuverability. Apart from this, few aspects of the eagle’s wing morphing techniques, its aerofoil, and its aerodynamic stability are also being highlighted. The aim is to highlight the bio-mimicable traits of an eagle which can be incorporated into bionic UAVs. This work acts as a base for current and future works involving slotted wingtips and bionic control surfaces. The traits discussed are being used to design mechanical control surfaces and wingtips that resemble the eagle’s slotted wings and control surfaces. These works when combined with compliant mechanisms can help improve roll and yaw control of a UAV along with drag reduction. This review also highlights the aerodynamics of flapping; specifically of the hummingbird. From the hummingbird’s aerodynamics to its hovering techniques; all of its main features are being highlighted. These birds have demonstrated a wide range of aerodynamic traits which if mimicked to near perfection could pave the way for new-age drones. Maneuverability and enhanced aerodynamic optimality could be the outset of extreme sustainability measures with these birds paving the way with their evolutionary flight measures. Apart from their aerodynamic traits, a few aspects of their wing morphing techniques and their evolutionary hereditary traits are also being highlighted.

“…The first one is considered as powered flight mode and it comprises of wing flapping and the hovering flight mode. The second one is considered as unpowered flight mode and it comprises of the soaring and gliding [1]. The main purpose of the bird's wing is similar to its mechanical counterpart (the airplanes), which is lift generation.…”

The optimal aerodynamic traits of the natural flyers have always been a foundation for the designing of bionic drones. In this paper, the aerodynamic soaring capabilities of the albatross and eagle are discussed in detail along with the eagle’s control surface aerodynamics. The bell shaped lift distribution characteristics exhibited by the albatross are also discussed along with its subsequent sub traits such as proverse yaw, wing-tip vortices and so on. The main soaring dynamics discussed are the dynamic soaring exhibited by the albatross and the utilization of thermal updrafts for thermal soaring by the eagle. Apart from these, the different control surfaces and their actuations along with wing morphing techniques are also highlighted. A proper and near perfect manifestation of the traits of natural flyers could be a harbinger to near perpetual modern aircrafts. Aerodynamics and propulsion system are the areas of research that are of concern in this manuscript.
