Problems solved by technology

At the front and rear edges of the upper and lower arcs of the traditional rotor, there is no continuous chord-wise and span-wise fiber reinforcement layup. During the aerobatic flight of the model helicopter, the leading edge of the rotor-the most stressed and the root of the beam wing The upper and lower curved surfaces at the connecting shaft hole of the fiber reinforced body are very easy to produce glue, which leads to the splitting and breaking of the skin of the rotor, the disintegration of the rotor in the air, and after being thrown out, it causes a major flight accident that hurts human life

Embodiment 1

[0063] Choose pure titanium foil and carbon fiber cloth, such as one of unidirectional cloth, two-way weave plain weave, twill weave, five satin weave, eight satin weave or two-way 45° three-dimensional weave cloth, each impregnated with epoxy resin glue, making The two-layer carbon fiber cloth with epoxy resin as the matrix is ​​interlayered with pure titanium gold foil, and the rotor part is pre-preg.

[0064] The carbon fiber cloth impregnated with epoxy resin glue is cut into the length with the perimeter of the two outer surfaces of the male mold, and the pure titanium gold foil soaked with epoxy resin glue is cut into the length with the perimeter of one outer surface of the male mold; On the male mold pre-coated with release agent, spread the carbon fiber cloth with two outer surface perimeters on the male mold, and spread the titanium gold foil on the other unrolled carbon fiber unidirectional cloth , put it on the rolling platform machine for rolling and rolling, then...

Embodiment 2

[0068] Use pure titanium foil and high-strength high-modulus polyethylene (PE) bulletproof fiber bidirectional woven fabric to impregnate high-strength high-modulus polyethylene (PE) bulletproof fiber resin glue respectively to make a high-strength two-layer high-strength high-strength high-modulus polyethylene (PE) bulletproof fiber resin glue as the matrix. High-modulus polyethylene (PE) bulletproof fiber two-way braided cloth interlayered with pure titanium gold foil pre-impregnated multi-directional molded shaped rotor.

[0069] The high-strength and high-modulus polyethylene (PE) bulletproof fiber bidirectional woven cloth impregnated with epoxy resin glue is cut into the length of the perimeter of the two outer surfaces of the male mold or the male mold segmented carcass, and impregnated with high-strength high-modulus polyethylene (PE) ) The pure titanium gold foil material of bulletproof fiber resin glue is cut to have the length of an outer surface perimeter of the mal...

Embodiment 3

[0072] Using pure titanium gold foil and aramid fiber two-way weaving cloth, each impregnated with phenolic resin glue to make a two-layer aramid fiber two-way weaving cloth with phenolic resin as the matrix, prepreg adhesive multi-directional mold pressing with pure titanium gold foil interlayer diameter craft rotor.

[0073] The aramid fiber two-way woven cloth impregnated with phenolic resin glue is pre-cut into lengths with a male mold or two outer surface perimeters on an aluminum alloy / polycarbonate carcass (airfoil segmented body structure), Pure titanium gold foil impregnated with phenolic resin glue, pre-cut to a length having the perimeter of one outer surface of the male die. On the male mold pre-coated with release agent, spread the aramid bidirectional weaving cloth cut with two layers on the male mold for one layer, and spread the titanium gold foil on the other unrolled aramid bidirectional weaving cloth On the cloth, rolled and rolled, made of aramid two-way w...

Abstract

The present invention relates to rotary wing of simulation helicopter and its making process and curing mold. The rotary wing includes carcass and covering, and the covering includes at least one closed reinforcing layer of reinforcing material carbon fiber, aramid fiber, polyethylene fiber, titanium foil and/or glass fiber. The making process includes making carcass, making covering and pressing to integrate the carcass the covering. The curing mold is one combined mold including upper mold and lower mold and with notch, positioning lobe and dovetail groove. The technology of the present invention may be used in making various kinds of simulation flyers.

Description

technical field [0001] The invention relates to flight equipment, in particular to a rotor of a model helicopter, a manufacturing method and a curing mold thereof. Background technique: [0002] At present, the rotors of model helicopters in the world are made of pure carbon fiber unidirectional cloth, bidirectional woven cloth or glass fiber cloth. After the upper and lower arcs of the rotor are respectively pressed and formed, a straight metal strip is added, and one end is processed into Ring shape, placed on the reinforcing platform of the connecting shaft hole of the rotor, as the reinforcement of the connecting shaft hole of the rotor, and the counterweight functional structural part of the chord to the center of gravity, it is bonded with glue for the second time. Other parts - filled with foam material. At the front and rear edges of the upper and lower arcs of the traditional rotor, there is no continuous chord-wise and span-wise fiber reinforcement layup. During t...
