PURPOSE: An air rocket for learning is provided to enable a user to directly experiment and measure the flying distance of a rocket according to different compressive force generated by compressing a different amount of air. CONSTITUTION: A rocket body(21) with a preset diameter and length includes a penetration groove. A heading(22) is fixed and combined with the front end of the rocket body. A wing(23) is fixed and combined with the outer side behind the rocket body. A pair of fixing plates(24) are fitted to the rocket body. A weight center(25) is interposed between a pair of fixing plates. A rocket(20) is comprised of an compressed air plate fitted to the rocket body. An air compression tub(31) has an air discharge hole(31a) and is made of soft materials. A launching tube(32) is fixed to the air outlet of the air compression tub and the penetration groove inside the rocket body. |
