Problem Statement
- In the present era, there is a growing possibility for the use of aerial robotic system or unmanned aerial vehicle (UAV) in multiple applications. There is a renewed interest in designing such systems to achieve better performance.
- The multirotor/quadrotor fits into the class of unmanned aerial systems and the critical parameters of a multirotor are its size, payload carrying capability, and endurance.
- One of critical factors to decide the utility of the quadrotors for a particular application is its payload capacity. The usual practice to increase payload carrying capability is by increasing the size of propeller or increasing the number of rotors . However, increased no. of rotors and size of the rotors in conventional design is not considered as a good alternative.
- Hence, the present patent is introduced to address the above issues in an efficient manner.
Technology
- Present Patent describes an unmanned aerial vehicle (UAV) configuration comprises more than one frames, plurality of motors, plurality of propellers, landing gears and a standoff, designed efficiently and illustrated in figures.
- Said patent relates to a vertically offset overlapping propulsion system (VOOPS).
- VOOPS is a characteristic propeller configuration with a layered design, featured in smart chart hereinbelow.
- VOOPS allows to use propellers with larger diameter without increasing footprint;
- VOOPS based design provides better maneuverability as the rotors are closer to the center of the gravity reducing the moment of inertia ;
- VOOPS guarantees better endurance and payload lifting capability for the same size;
Key Features/Value Proposition
Technical Perspective:
- Present Patent provides efficient configuration which allows assembling propellers with larger diameter, without increasing its footprint.
Industrial Perspective:
- UAV design is configured professionally without affecting footprint and disturbing its actual size;
- Present UAV configuration achieves better performance in terms of payload capacity, endurance and power rating.
