Abstract: The heat resistant structure of the flying body is provided with a tip part and a body part. The tip part is arranged in a front end of the flying body with respect to a direction of travel of the flying body. The body part is arranged in a back direction from the tip part with respect to the direction of travel of the flying body. The tip part is provided with a surface member, a base part, and an insulation member. The surface member is arranged on an outer surface of the tip part and has a melting point higher than a desired temperature. The base part couples the surface member to the body part. The insulation member is arranged between the surface member and the base part., and thermally insulates the base part from the surface member.

Abstract: A target tracking device to estimate a position of a target with high accuracy will be provided. The target tracking device is provided with a communication device and a processor. The communication device performs communication with a plurality of observation satellites that observe the target. The processor executes a selection of satellites, a setting of a schedule and an estimation. The selection of satellites includes selecting two or more selected satellites that observes the target among the plurality of observation satellites. The setting of the schedule includes determining an observation schedule for each of the two or more selected satellite to observe the target and transmitting an observation request signal that represents the determined observation schedule to a corresponding selected satellite. The estimation includes estimating the position of the target based on two or more pieces of high-precision observation information respectively observed by the two or more selected satellites.

Abstract: A glide control device includes a communications device configured to communicate with an attitude control device of a glide vehicle; and a processor configured to control the attitude control device. The processor is configured to control the attitude control device to generate a downward lift force when a velocity of the glide vehicle is higher than or equal to a first astronomical velocity.

Abstract: In a display apparatus of an interception area, a first detection device scans a first area containing at least a part of a firing range of a first weapon to detect an obstacle. A first terminal calculates the first interception area in which the first weapon is possible to intercept, based on data of the detected obstacle and data of the first weapon; calculates a first display area showing the first interception area on a screen based on the first interception area; receives second area data generated by a second terminal, and calculates a second display area based on the second area data. The second display area shows on the screen an area in which a second weapon is possible to intercept. The first terminal displays the first display area and the second display area.
