Abstract: PURPOSE: A separable dual antenna for a rocket is provided to improve a success rate of a rocket launch by maintaining the optimum electric wave sensitivity after separation by respectively including separable antennas inside and outside a nose faring. CONSTITUTION: A mount unit(10) forms the inside of a rocket. A nose faring(20) is separable from the rocket and surrounds the mount unit. A transceiver system(30) is formed on the mount unit. An internal antenna(40) is installed in the inner side of the nose faring and is connected to the transceiver system to amplify the transmission and reception sensitivity of the transceiver system. An external antenna(50) is installed on the outer side of the nose faring and is connected to the internal antenna to amplify the transmission and reception sensitivity of the transceiver system.

Abstract: An external pipe/duct fixing device of a pressure resistant container is provided to prevent damage due to clamping by fixing an object by using a fixing member and a metal band, and to fix a pipe or a duct easily. An external pipe/duct fixing device of a pressure resistant container includes a metal band(10), a fixing member of an object(20), a bottom fixing member(90), a first fastening unit, a clamp, and a second fastening unit. The metal band covers an outer circumference of the pressure resistant container(100). The bottom fixing member is arranged on the bottom of the metal band. The first fastening unit fixes the bottom fixing member and the fixing member of the object on the metal band. The clamp includes a fixing part and a fixing piece. The fixing part surrounds the outer circumference of the object. The second fastening unit fixes the clamp on the fixing member of the object.

Abstract: PURPOSE: A solenoid valve with a coil cooling method using working fluid is provided to form a cooling passage covering a solenoid and to cool the solenoid by transferring low temperature working fluid, expanding some of the working fluid, to the cooling passage. CONSTITUTION: A solenoid valve with a coil cooling method using working fluid comprises a valve body, a poppet(200), a solenoid(300), a solenoid cover(310), an discharge port(420), an auxiliary passage(140), and a throttling device(500). The valve body comprises an inlet port, an outlet port, and a fluid passage interconnecting the inlet port and the outlet port. The poppet opens and closes the fluid passage by lifting. The solenoid is connected to the poppet to lift the poppet according to the supply of power. The solenoid cover is installed to cover the solenoid and a cooling passage is formed between the solenoid and the solenoid cover. The discharge port is formed in the solenoid cover to discharge the fluid in the cooling passage to the outside. The auxiliary passage is formed in the valve body to interconnect the fluid passage and the cooling passage and selectively connects by the lift of the poppet. The throttling device is formed in a boundary of the auxiliary passage and the cooling passage.
