Disclosure of Invention

The invention aims to: in view of the above disadvantages of the prior art, the present invention provides a novel spring characterized by a force to extension length relationship: the force is gradually increased along with the increase of the stretching length, the force is increased from small to large and then increased to small, the continuous time or the continuous distance can be controlled in a large force state, and the control can be carried out according to the number of the movable diamonds. The characteristic of the aircraft carrier catapult can be applied to an aircraft carrier catapult to catapult a carrier-based aircraft to take off.

The invention aims to realize the purpose, and the novel spring is characterized in that: it includes at least one movable diamond inner angle which can be changed, and the same side between upper end point and lower end point is respectively equipped with tension spring. The novel spring is characterized in that: the internal angles of the two identical movable rhombuses can be changed and are connected together by a common end point, two sides passing through the common end point are divided into four sections by the end point to respectively form two adjacent sides of two adjacent rhombuses, and the same sides between the upper end point and the lower end point of the same rhombus are respectively provided with a tension spring. The novel spring is characterized in that: the internal angles of the same movable rhombuses can be changed and are connected together by a common end point, two sides passing through the common end point are divided into four sections by the end point to respectively form two adjacent sides of two adjacent rhombuses, and the same sides between the upper end point and the lower end point of the same rhombus are respectively provided with a tension spring.

Novel spring aircraft carrier catapult, characterized by: the novel spring formed by the diamonds compresses the left end point and the right end point, and releases energy through brake control to catapult the carrier-based aircraft to take off.

And tension springs are respectively arranged on the same side between the upper end point and the lower end point, and the tension springs can be other elastic elements. The end points can be shafts, through nails, rivets and bolts (turnbuckles at two ends of a middle rod), and bearings can be added on the same two sides.

The present invention has: the new spring is essentially different from the existing springs, the force is proportional to the length of the extension: hooke's law, but the novel spring force of this invention is not proportional to the length of extension, it is that the increasing force of length along with extension is from small to large at first, and then from large to small, if put the force and two variables of the length of extension in the rectangular coordinate system, its picture is similar to the parabola, as the picture, figure 3, figure 4, figure 5 are a diamond, two diamonds, three diamonds compress the picture of the force and length of extension that left end point and right end point respectively, figure 3, figure 4, figure 5 are the real object made of the novel spring of this invention, the experiment gets the data and draws the picture, through figure 3, figure 4, figure 5 compares, can get the area of the bigger force of the diamond number that makes up the novel spring is bigger, explain that the bigger force can last, the diamond number is bigger, the lasting distance is longer. Adopt a plurality of rhombuses to constitute novel spring aircraft carrier catapult, have: the size of the ejection force is adjustable, the extension spring is adjusted in the novel spring, the extension spring tension is larger, the ejection force is larger, the acceleration distance is adjustable, the number of the novel spring diamonds is adjusted, the number of the diamonds is larger, the continuous distance is longer, the acceleration distance is longer, and the ejector can eject various airplanes or unmanned aerial vehicles with different sizes.
