Abstract

To achieve improvement in cargo loading property and inspection property, and multiuse of an unmanned rotary-wing aircraft.SOLUTION: An airframe body of an unmanned rotary-wing aircraft is covered with a fiber material, a fastener 3 is provided on a surface of an airframe cover which is made of the fiber material, the fastener is opened, and a large opening is formed in the aircraft body by utilization of flexibility of the fiber material, whereby loading of a cargo 7 into an airframe, inspection of an airframe interior and part replacement can be easily performed. The cover of the fiber material, which covers the airframe, is replaced as clothes changing, and thus, heat-resistant performance, chemical-resistant performance, blade-resistant performance, waterproof performance and a design thereof is changed according to uses and use environments of the aircraft.SELECTED DRAWING: Figure 2

Description

The present invention relates to the fuselage structure of an unmanned rotorcraft.

Helicopters that fly on rotary wings, and drones and unmanned aerial vehicles that fly by autopilot, commonly called multicopters, are made of inflexible materials such as metal, carbon fiber, and plastic.

A practical test of cargo transportation by unmanned rotorcraft is being conducted.

Improved loadability and inspection of unmanned rotorcraft and increased versatility

Fiber material is used as the covering material on the surface that covers the aircraft.

Access to the interior of the aircraft is done by opening and closing the fasteners.

It is possible to replace the fiber material covering that covers the airframe.

Since the fiber material is used for the exterior covering of the airframe and the inside of the airframe is accessed by opening and closing the fastener, the weight of the airframe can be reduced.

A baggage can be loaded inside the fiber material coating and transported while protecting the baggage from the external environment. By using a fastener, the baggage can be easily stored and the aircraft can be maintained.

The chemical resistance, heat resistance, blade resistance, waterproof performance, and design of the fuselage can be changed by changing the material and structure of the fiber material and the fastener.

Cover the aircraft of the rotorcraft with a fiber covering.

A fastener for accessing the inside of the fuselage is provided on the fiber material coating on the fuselage surface.

A hook-and-loop fastener, a line fastener, a point fastener, etc. are used for a fastener.

The fiber material covering that covers the fuselage is structured so that it can be replaced.

1 and 2 are a side view and a bottom view of a rotorcraft having four rotor blades.

The fiber material covering 1 covering the fuselage body 6 has a space for storing the luggage 7 therein.

The fastener 3 provided on the fiber material cover 1 on the surface of the machine body can be opened to store the luggage 7 inside the fiber material cover 1, replace the battery, supply fuel, etc., and check the machine body.

Since the fiber material coating 1 on the surface of the machine body is flexible, a large opening can be obtained on the surface of the machine body by opening the fastener 3 to the left and right.

If necessary, a protective part made of an impact cushioning material or the like is attached to the space inside the airframe on the back of the fiber material coating 1 to protect the airframe body portion 6 and the luggage 7.

The fastener 3 is provided with a lock function so that it does not open during flight after being closed.

When observing the outside from the inside of the airframe or checking the internal equipment from the outside of the airframe, a window 4 is provided on the fiber material covering 1 covering the airframe body as necessary.

The structure is such that the arm part can be removed at the contact point between the arm part 8 connecting the fuselage body part and the rotor blade 2 and the fiber material coating 1, and sealing treatment is performed at the same part as needed to prevent moisture and dust from entering the machine body. The structure can be prevented.

The fiber material covering 1 covering the space for loading the fuselage body 6 and the luggage 7 is exchanged.

The body part 6 is taken out from the opening of the fastener 3 of the fiber material covering 1 that removes the arm part 8 connecting the rotor 2 and the body part 6 and covers the body part 6.

Even when the airframe body 6 has a suspension device or an external observation device for attaching the device to the outside of the fiber material coating 1, the external device can be removed or the fiber material in the same manner as the arm portion 8 of the rotor blade 2. The fiber material coating 1 and the fuselage body 6 are separated from each other through the opening of the coating 1.

It is possible to change the performance and design of the fuselage by changing the fiber material coating 1 covering the fuselage fuselage 6 to a fiber material with a different color or a different color.

It is also possible to replace the fiber material coating without removing the exterior parts such as the rotary blades and the arm portion connecting the rotary blades by forming the fiber material coating to wrap around the fuselage body.

When carrying luggage with an unmanned small rotorcraft, the exterior can be made of a fiber material, so that the luggage can be protected and transported from the external environment with a minimum increase in the weight of the aircraft, and the luggage can be taken out easily.
