    [0013] The specific embodiments of the invention will be further described in combination with the appended drawings and embodiments. The following embodiments are only used to explain the technical solution of the invention more clearly, and cannot limit the protection scope of the invention.
    [0014] As shown in Fig. 1- Fig. 11, the embodiments relate to a slide rule style flight computer, which includes a flight computer 1. The flight computer 1 contains a front disc and a back disc. The front disc and the back disc are connected and fixed by a positioning clips. The front disc includes a front base disc and a front rotary disc. The front rotary disc are rotably fixed on the front base disc. The back disc includes a back base disc and a back rotary disc, and the back rotary disc are rotably fixed on the back base disc. Positioning clips includes the left positioning clip 3 and the right positioning clip 4.The upper side of the left positioning clip 3 is connected and fixed with the bottom side of the front base disc. The bottom side of the left positioning clip 3 is connected and fixed with the upper side of the back base disc. The upper side of the right positioning clip 4 is connected and fixed with the bottom side of the front base disc. The bottom side of the right positioning clip 4 is connected and fixed with the upper side of the back base disc, and a slide-rule 2 is arranged between the left positioning clip 3 and the right positioning clip 4. The slide-rule 2 can move can be pulled and moved between the left positioning clip 3 and the right positioning clip 4, and between the front base disc and the back base disc. The slide-rule 2 is respectively connected with the left positioning clip 3 and the right positioning clip 4 respectively. Damping generating device 5 is arranged on one side of the right positioning clip 4 close to the slide-rule 2. The embodiments for the slide rule style flight computers are all durable, waterproof, lightweight, easy-carry and high accuracy.
    [0015] Specifically, the materials of the front base disc and the front rotary disc may be transparent plastic; the materials of the back base disc and the back rotary disc may be transparent plastic.
    [0016] In addition, the bottom side of the front base disc and the bottom side of the front rotary disc are printed with degree scales and texts. The degree scales and texts on the bottom side of the front base disc are covered with ink layers. The ink layers on the bottom side of the front base disc is covered with a protective film. The degree scales and texts on the bottom side of the front rotary disc are covered with ink layers. The ink layers on the bottom side of the front rotary disc is covered with a protective film.
    [0017] The upper side of the back base disc and the upper side of the back rotary disc are printed with degree scales and texts. The degree scales and texts on the upper side of the back base disc are covered with ink layers. The ink layers on the upper side of the back base disc is covered with a protective film. The scales and texts on the upper side of the back rotary disc are covered with ink layers. The ink layers on the upper side of the back rotary disc is covered with a protective film.
    [0018] In the process of use, it is convenient to measure by rotating the front and back rotary discs while moving the slide-rule 2. When the slide-rule 2 is pulled and moved back and forth between the left positioning clip 3 and the right positioning clip 4, the damping generated by the damping generating device 5 on the right positioning clip 4 can gently position the slide-rule 2 on the left positioning clip 3, so as to prevent the slide-rule 2 from falling off easily. It also improves the accuracy of locating the slide-rule when converting with the rotary disc in the process of inserting. As a layer of protective film is applied on the surface of the degree scales and texts on the front base disc, the front rotary disc, the back base disc and the back rotary disc, the degree scales and texts are definitely not be rubbed off by users in the process. Hence, it extends the life of use.
    [0019] Although the foregoing embodiments have been described in some detail for purposes of clarity of understanding, the invention is not limited to the details provided. There are many alternative ways of implementing the invention. The disclosed embodiments are illustrative and not restrictive.
