Abstract: PURPOSE: An unlocking device of a missile is provided to improve assembly efficiency and missile performance by releasing a propeller using a string. CONSTITUTION: An unlocking device of a missile(10) comprises locking units, a string(30), and unlocking units. The locking units fixe a propeller(20) to the missile. The locking units and the unlocking units are formed in both sides of the propeller. The string is arranged in the rear end of the propeller. And the string is broken by heat of the propeller. The unlocking units are connected by the string, and release the missile by the broken string.

Abstract: A method for preparing inorganic binder is provided to obtain inorganic binder which is stable in long-term storage and is curable at 200 °C or less and to shorten processing time compared with conventional water bath method. A method for preparing inorganic binder comprises the steps of: mixing H3PO4 and Al(OH)3 with CrO3 solution; and stirring the mixed solution and then applying microwaves. A mole composition rate of P, Al and Cr in H3PO4, Al(OH)3, and CrO3 is P/(Al + Cr) = 2~2.18. The method further comprises adding at least one 0.03~0.1 mol selected from Cu, Fe, S, Zn, Mg, F, and K per phosphorus(P) 1mol.
