In the future, vehicles may be required to achieve multiple mission objectives in a single platform. To enable this capability the concept of variable geometry has been proposed as a means to extend the capability of current air vehicle platforms. This requires the development of seamless aerodynamic structures that can undergo large scale changes in wing geometry. Flying bike, or roadable aircraft is an automobile that can legally travel on roads and take off, fly, and land as an aircraft. Flying bike in the future will just look like today's sports bikes, but as they travel by flying there...

A bird or insect sized flapping wing Micro Aerial Vehicle (MAV) whose wingspan is of the order of a few centimeters cannot be physically built or flown today; they can be designed, tested, flown and studied on the computer using numerical simulation technique. While finalizing a design is quite significant in case of MAV, understanding the flow field environment in which MAVs fly is equally a requirement. The flow field environments encountered by Micro Air Vehicles are fundamentally unsteady - whether for fixed-wing, rotary-wing or flapping-wing configurations. High lift generation is...
