, Description:BACKGROUND
Technical Field
[0001] The embodiments herein generally relate to an unmanned aerial vehicle, and, more particularly, relates to an improved design of the unmanned aerial vehicle for placing two propellers to achieve high speed in desired direction that is substantially horizontal.

Description of the Related Art
[0002] An unmanned aerial vehicle, or drone also called UAV is a flying machine of unmanned aviation (eg. for monitoring, exploration, reconnaissance, as target drone) for measurement purposes or fitted with weapons equipped particularly in combat zones is used. Drones can be used eg military, secret service or civil. A drone is flying unmanned either automated via a computer program, or from the ground via radio signals or satellite radio controlled. Depending on the application and equipment drones can carry payloads such as rocket for a military attack. Inherently, a UAV pitches forward to achieve forward velocity. This pitch motion can cause enormous amount of drag depending on the pitching angle and the angle of the wind. At high-speeds this drag will be considerably high. In conventional methods, two propellers may be used to lift the UAV. But the two propellers are not placed at pitch axis or roll axis or yaw axis to provide high speed in desired direction to the UAV. Therefore no systems have yet been able to implement or achieve high speed in the desired direction by placing two propellers.
[0003] Accordingly, there remains a need for improved design of an unmanned aerial vehicle for placing two propellers to achieve high speed in desired direction.
