High endurable multi-rotor craft

Abstract

The invention belongs to the field of craft design, and relates to a craft which can vertically take off and land and can also carry out a gliding flight by using fixed wings. According to the invention, a craft which can concurrently have the advantages of flexibility and convenience of multi-rotor flight and the advantages of large load and long endurance of fixed wing aircrafts is designed. According to the invention, a multi-rotor craft is taken as a basic form, and fixed wings are taken as auxiliary parts. The fixed wings can be collapsed and expanded, folded and flatted, or overturned for resetting as required. The craft can be powered by multiple rotors or power mechanisms, and rotor parts can also be overturned or covered so as to provide a better aerodynamic performance and provide forward or rising power. In the process of rising or environmental constraint, the craft is mainly powered by rotor mechanisms until flying to a stable height, the fixed wings can be expanded in proper condition, the craft is in a gliding state, and the rotors (or other power supply devices) can be overturned for propelling. After flying to a certain height, the craft carries out gliding by the fixed wings.

Description

technical field [0001] The invention belongs to the field of aircraft design, and relates to an aircraft that can take off and land vertically and can also glide with fixed wings. Background technique [0002] Fixed-wing aircraft is a traditional model with excellent endurance and load capacity. But the problem is that it must take off and land on the runway, and requires certain take-off and landing facilities, and the operation in flight is not flexible enough. [0003] Rotorcraft represented by helicopters have good maneuverability and adaptability to complex terrain and complex conditions, and are widely used in emergency rescue, emergency rescue and other fields. [0004] It has always been a dream of aircraft designers to design an aircraft that has high endurance flight and take-off and landing capabilities in a small space. At present, in practical application, relatively mature fixed-wing aircraft that can take off and land vertically include jet aircraft such as ...

Problems solved by technology

But the problem is that the endurance is too weak, and the aerodynamic structure is not conducive to long-term endurance

[0007] Generally speaking, the current problem of multi-rotor and single-rotor aircraft is the lack of endurance. They must rely on the continuous rotation of the rotor to provide the power to rise and advance. This method is flexible but has low energy efficiency and weak endurance. Once the rotor fails or Is the loss of power, the aircraft can not glide, thus reducing safety

Fixed-wing aircraft has high inertia, high take-off and landing requirements, difficulty avoiding obstacles, unable to hover, and overall not flexible enough to meet short-distance use requirements in complex situations
