Abstract: The present invention relates to a method and a system for generating a combat plan based on forward/backward delay expectation (FBDE). According to an embodiment of the present invention, the method for generating a combat plan based on FBDE comprises the steps of: generating an FFFT-table (S100); aligning targets included in a set of un-assigned target (SUAT) according to a predetermined priority (S200); determining whether there are targets included in the SUAT (S300); selecting a target (x) with a highest priority among the targets included in the SUAT (S400); selecting a launcher (s) with a minimum expected fired delay (EFD) of the selected target (x) (S500); assigning the selected target (x) to a fire time line (FTL) of the selected launcher (s) (S600); and updating fire execution time (FET) values of an FET-table of the selected launcher(s) (S700). According to the present invention, a combat plan is computed based on the FBDE in situations where multiple weapons are fired from the same launcher so as to minimize a delay time from an optimal firing time, thereby achieving a rapid response to a high-speed target.

Title: Fin tube heat exchanger having shrink ring and method for manufacturing the heat exchanger
Inventor: CHO HAN YONG
IPC: F28F1/30
Filed: 2015-05-20
Abstract: The present invention relates to a heat exchanger and, more specifically, to a fin tube heat exchanger which exchanges heat between air and a heat exchanging medium. The fin tube heat exchanger according to the present invention comprises: a tube having at least one fluid passage formed in a longitudinal direction, through which a first working fluid circulates and passes; a fin having a collar tightly fixed to the tube; and a shrink ring which presses the collar by residual stress to maintain a condition in which the collar is tightly fixed to the tube, and is formed in a hollow cylindrical shape. Also, the collar may comprise at least one cut slit formed on an end thereof. The cut slit facilitates elastic deformation of the end of the collar by an external force acting towards a center in a radial direction from the end of the collar. The heat exchanger according to the present invention tightly presses the collar and the tube against each other by shrinking of the shrink ring and maintains the condition in which the collar and the tube are tightly pressed against each other by thermal stress remaining in the shrink ring. Therefore, the heat exchanger prevents a case where the collar of the fin and the tube are imperfectly pressed against each other by a tube expansion defect or a case where the collar of the fin and the tube are separated by a difference in thermal expansion coefficient or a change in thermal expansion coefficient. Therefore, the heat exchanger has excellent heat transfer performance.
