Ornithopter
Project Description :
My paper is "ornithopter" where orni means bird thopter means wing so full meaning is bird wing.it's a type of small unmanned air vehicle which will by like a bird by flapping their wing. it will useful for multipurpose like deliveries,security,rescue and as well as for surveillance purpose. at the present time and in future we are going to be used drones. it will do all the operation whatever the operation we will do with the help of drones but the main thingis drone can be easily detect by the human eyes. but orni will not able to detect easily by human eyes because of its flapping wing.

as we know that in a simple aircraft wing is fixed but if we see to birds in the evening or morning time they fly in sky by flapping their wings so from their we came to across the idea of ornithopter.

The analysis of the flight of insects, birds and ornithopters is difficult because there is limited aerodynamic theory applicable for the large amplitude unsteady wing motions. Furthermore the complex wing shapes and wing motions encountered in insect and bird flight entails complex aerodynamic interactions. A systematic theoretical and experimental study has been pursued by the senior author for the past several years to gain a better understanding of the aerodynamic, dynamic and mechanical problems of flapping wing flight. The primary intent has been to establish a strong technical base necessary for the development of the ornithopter as an alternative to the helicopter. The helicopter is best suited for hovering flight and suffers greatly reduced efficiency as forward speed is increased. On the other hand, the ornithopter can achieve hovering flight, albeit with much more mechanical complexity, but promises high efficiency in forward flight. The method of attack for this study of the ornithopter has been to depart gradually from the conventional aircraft configuration so that the large body of knowledge accumulated in the development of the airplane could be applied to the study of the ornithopter. In this paper the results of the aerodynamic studies are presented because of their applicability to the modeling of insect and bird flight.Vinci began to study the flight of birds. The first ornithopters capable of flight were constructed in France. From 1884 on, Lawrence Hargrave built scores of ornithopters powered by rubber bands, springs, steam, or compressed air.
IDEA OF THE MODEL
In plane we know that wings are fixed but in the case of birds ,as we all know , they flap their wings in order to fly.During our last project “R.C. PLANE“, We came across the idea of this ornithopter and finally we decided to construct one of our own .In our earlier project, we had referred some videos inspiration and from the motion of ‘birds’ .With the help of the teachers,we tried to mimic the flapping mechanism of birds. The idea was to replicate the motion in nature through a machine i.e. ornithopter.
