APPARATUS FOR AERIAL TRANSPORTATION OF PAYLOAD
Disclosed is an apparatus ( 100 ) for an aerial transportation of a payload. The apparatus ( 100 ) includes a propeller unit ( 10 ) to provide a primary thrust whereas a plurality of propellers ( 50 ) is fitted around a body of the apparatus ( 100 ) to help in maneuvering and orientation control. The apparatus ( 100 ) employs gasoline as a primary source of energy that has a higher energy density than lithium polymer batteries. The apparatus ( 100 ) facilitates longer flight times. The apparatus ( 100 ) is useful for safe transportation of higher payloads and has vertical takeoff and land capability.
1 . An apparatus ( 100 ) for an aerial transportation of a payload, the apparatus ( 100 ) comprising:
a propeller unit ( 10 ) having a pair of top blades ( 2 ) and a pair of bottom blades ( 4 ) arranged in a coaxial counter-rotating configuration, the propeller unit ( 10 ) cable of rotating in any one of a collective mode and a differential pitch mode;
an engine ( 30 ) for driving the propeller unit ( 10 ) through a gearbox ( 20 );
a clutch ( 40 ) positioned between the engine ( 30 ) and the gearbox ( 20 ), the clutch ( 40 ) capable of disengaging in case of failure of the engine ( 30 ) to facilitate auto-rotation thereby enabling a safe descent;
a plurality of propellers ( 50 ) fitted around a body thereof, the plurality of propellers ( 50 ) adapted to help in maneuvering and orientation control; and
an electrical subsystem consisting of a battery and electronic speed controllers for controlling speed of the plurality of propellers ( 50 ).
2 . The apparatus ( 100 ) as claimed in claim 1 is a drone.
3 . The apparatus ( 100 ) as claimed in claim 1 is a drone operating on a technology of a vertical take-off and landing.
4 . The apparatus ( 100 ) as claimed in claim 1 , wherein the propeller unit ( 10 ) provides a primary thrust to the apparatus ( 100 ).
5 . The apparatus ( 100 ) as claimed in claim 1 , wherein the pair of top blades ( 2 ) is connected to the gearbox ( 20 ) through an internal shaft that is concentric with a shaft ( 6 ).
6 . The apparatus ( 100 ) as claimed in claim 1 , wherein in the collective mode, both blades ( 2 , 4 ) of the propeller unit ( 10 ) are deflected equally.
7 . The apparatus ( 100 ) as claimed in claim 1 , wherein in the differential pitch mode, the pair of top blades ( 2 ) and the pair of bottom blades ( 4 ) are deflected by different values.
8 . The apparatus ( 100 ) as claimed in claim 1 , wherein the plurality of propellers ( 50 ) is fixed-pitch propellers that are powered by a plurality of electric motors.
9 . The apparatus ( 100 ) as claimed in claim 1 , wherein the plurality of propellers ( 50 ) fitted around the body of the apparatus ( 100 ) are in a range of 3 to 16.
10 . The apparatus ( 100 ) as claimed in claim 1 , wherein the electrical subsystem is used to change roll and pitch attitudes of the apparatus ( 100 ).
