    l DK 2019 00797 A1 AUTONOMOUS MULTI-ROTOR AIRPLANE
    TECHNICAL FIELD OF THE INVENTION The invention disclosed herein generally relates to a multi-rotor airplane. More particularly, the present invention relates to an autonomous multi-rotor airplane used for skydiving.
    BACKGROUND Skydiving or parachute jump is a stimulating pleasurable sport activity and extremely popular around the world. Generally, skydivers or jumpers are reached to a desired high altitude by an airplane or aircraft and jump from the high altitude to get maximum flying time. Skydive airplanes or jump planes are used to pick up and carry a number of skydivers or jumpers from different locations to the desired high altitude for skydiving or parachute jump. Currently, the skydive airplanes or jump planes are incorporated with a single turbo engine or dual/twin turbo engines. The skydive planes are capable of taking at least — 10-15 skydivers simultaneously to the high altitude, for example, 3,000 to 15,000 feet in about 10 to 20 mins. The skydivers or jumpers could jump from an exit door of the skydive planes from the high altitude. However, the existing skydive planes are difficult to operate and control by one or more pilots or operators in bad weathers. This difficulty arises from the decrease in the situational awareness of the operator, which in turn, significantly decreases working efficiency and at the same time increases risks. The existing skydive planes are very expensive to operate and maintenance due to low efficiency. Further, the existing skydive planes are not comfortable for picking and dropping the new and experienced skydivers at different locations. In addition, the existing autonomous airplanes are used for different purposes, for example, transporting
    , DK 2019 00797 A1 goods. The autonomous airplanes may be remotely controlled or self-controlled by remote or onboard computers.
    The skydive airplanes or jump planes carry excess fuel above the minimum needed to compensate delays for each flight. The amount of fuel burned by an aircraft during a flight depends on many factors that range from the age and type of aircraft to the specific flight plan approved by air traffic control and any excess fuel required to be carried. The burning of liquid hydrocarbon fuels releases greenhouse gases such as carbon dioxide (CO2) and methane into the atmosphere and causes global warming.
    In the light of above-mentioned problems, it is need to provide a multi-rotor autonomous airplane for skydivers or jumpers that executes an optimal flight path based on the information, such as, wind direction, wind speed, and the desired altitude, given by the operator who is in direct contact with the flight controllers. There is also a need to provide a multi-rotor autonomous airplane, capable of picking and carrying one or more skydivers at a time to the desired high altitude within few minutes. Further, there is also a need to provide an environment-friendly multi-rotor autonomous airplane to safely pick up and comfortably drop the skydivers or jumpers at different locations and altitudes.
