Unmanned aerial vehicle with double engines, four shafts and four rotors

The invention discloses a highly reliable unmanned aerial vehicle with double engines, four shafts and four rotors. The unmanned aerial vehicle is composed of aero-engines, a rotor machine body, a power distribution transmission system, a flying control system and four rotor assemblies, wherein the rotor machine rotors are pitch-variable rotors and each rotor comprises a rotor rotation driving part and a rotor blade angle adjusting part. According to the unmanned aerial vehicle, two aero-engines are used for driving four rotors; each engine drives a pair of blades on a symmetrical axis and a speed reducing mechanism is additionally arranged between the engine and the blades; the rotor blade angle adjusting mechanism drives the pitch-variable blade to change the pitch, so as to change lifting force; the engines work in a relatively high efficiency section; postures such as hovering, fly forwards and backwards are realized by adjusting the pitch; and the flying control system is composed of an ARM, GPS and a three-axis gyroscope and is accurate and reliable. By adopting the double-engine scheme, when one engine fails, the attitude of the vehicle can be maintained by improving the power of the other engine, so as to land safely; and the unmanned aerial vehicle has high reliability.

Automobile brake disc and manufacturing method thereof

The invention discloses an automobile brake disc which comprises a brake disc body. The brake disc body is made of aluminum alloy. The two work faces of the aluminum alloy brake disc body are each provided with an abrasion-resistant layer in a composite mode. The abrasion-resistant layers are made of a ceramic reinforcing material. The abrasion-resistant layers made of the ceramic reinforcing material are metallurgically combined with the aluminum alloy brake disc body through the squeeze casting technology. The brake disc is low in weight, good in abrasion resistance and cooling performance, long in service life, low in maintenance cost, and capable of reducing automobile oil consumption, improving the passage capacity of an automobile, shortening the brake distance and improving safety of the automobile. According to a manufacturing method of the brake disc, by means of selective local strengthening and the squeeze casting technology, the two work faces of the aluminum alloy brake disc body are each provided with one abrasion-resistant layer made of the ceramic reinforcing material in the composite mode, the abrasion-resistant layers made of the ceramic reinforcing material are metallurgically combined with the aluminum alloy brake disc body so that abrasion resistance of the work faces of the brake disc can be guaranteed, and raw material cost and machining cost of the brake disc are reduced.

Non-sun-synchronous orbit satellite double-shaft sailboard control method

The invention discloses a non-sun-synchronous orbit satellite double-shaft sailboard control method. A double-shaft sailboard is a solar sailboard structure which has two rotational degrees of freedom and of which the two rotating shafts can independently control work. The double-shaft sailboard control method comprises a control method of each single-shaft sailboard in the double-shaft sailboard and an implementation method during double-shaft cooperative work of the sailboard. In the single-shaft control method of the sailboard, measurement modes and rotation strategies for the sailboard in different work modes of the satellite are mainly designed. In the double-shaft cooperative work method, the working order of each single shaft and the rotation logic are specified. The inconvenience that a non-sun-synchronous orbit satellite needs to frequently perform attitude maneuver to ensure the sailboard tracks the sun is solved by applying the double-shaft sailboard control method on a satellite. By the method, the satellite can track the sun in real time on orbit by controlling the rotation of the sailboard, so that the energy supply on the satellite is guaranteed, and the requirement of the satellite over the ground directional triaxial stability is met.

Deformable multi-mode ground and air flying robot

A deformable multi-mode ground and air flying robot comprises a body, an automatic pilot, wing arm devices, hub devices and a suction device. The body is provided with the four sets of wing arm devices in a cross shape. The wing arm devices comprise large wing arms, small wing arms, rotation joints, installation supports, motors and damping sleeves. The hub devices are installed on the four sets of wing arm devices respectively and are driven to run through motors. The suction device is installed on the upper portion of the body and used for being sucked to the surface of an object with the assigned angle. The automatic pilot is installed on the body and drives the hub devices and the suction device to run. The automatic pilot drives the rotation joints of the wing arm devices to rotate so that the small wing arms can drive the hub devices to rotate to the assigned angle, and thus switching of a flying mode and a ground walking mode is achieved. The deformable multi-mode ground and air flying robot has the advantages of being low in power consumption, high in environment adaptability and multi-task handling capability, good in structural stability and high in mobility, and is suitable for multi-mode operation and capable of meeting various task requirements under various complex severe environments.
