Problems solved by technology

Many traditional flapping-wing aircraft have realized the flapping action, but they still cannot highly imitate the movement of bird wings, the efficiency is not high and the cost is high
However, the vertical take-off and landing power plant based on the rotary flapping wing is blank in the market, and there is no simple and effective method to control the vertical take-off and landing power plant based on the rotary flapping wing to achieve ascent, descent and hovering

Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0020] The present invention includes a blade 1, a large bearing 2, a connecting shaft 3, a control system 4, a steering gear 5, a steering head 6, a linkage rod 7, and a small bearing 8. The blade 1 is a "drop-shaped" head and a circular The section formed by the tail is a long strip of lightweight aluminum strip stretched. The "drop-shaped" head of the cross-section of the blade 1 is hollowed out in the middle to reduce the overall mass and improve rigidity. The "water drop" of the blade 1 There should be at least 1 cm gap between the shaped head and the rounded tail of the adjacent leaf. The cylindrical tail of the cross-section of the blade 1 is solid in the middle of the axis, and there are "concave" holes on both sides for connecting with the connecting shaft 3. The connecting shaft 3 is a "convex"-shaped column at the head and a cylindrical tail. Comp...

Abstract

The invention discloses a blade opening and closing mechanism based on a rotary flapping wing vertical take-off and landing power device, belongs to the field of aerospace, and particularly relates totake-off and landing control of a novel rotary flapping wing vertical take-off and landing power device. The blade opening and closing mechanism based on the rotary flapping wing vertical take-off and landing power device is installed at the top of the rotary flapping wing vertical take-off and landing power device; a steering head is driven to rotate through rotation of a steering engine, and alinkage rod is combined, so that all the blades are adjusted to simultaneously move at the same speed, and the opening and closing angle of the blades directly affects the size of the air flow in order to control the lift force of the vertical take-off and landing device. The blade opening and closing mechanism has the advantages of being small in overall weight, low in energy consumption, simplein structure, high in reliability and the like.

Description

technical field [0001] The invention belongs to the field of aerospace, and in particular relates to a take-off and landing control of a novel rotary flapping-wing vertical take-off and landing power device, which is suitable for solving the problem of inconvenient take-off and landing control of the new rotary flapping-wing vertical take-off and landing power device. Background technique [0002] The vertical take-off and landing power device has developed rapidly in recent years, and scientific research institutions and enterprises in many countries are scrambling to develop and experiment. The aircraft with the vertical take-off and landing power device does not need a special airport and runway, which reduces the cost of use and has no site restrictions. , enrich the scope of application. Among them, the rotary flapping flight is a flying method that imitates the movement of the wings of birds during flight. It is a low-energy and high-efficiency flying method. It can mo...
