AUTOMATIC DRAFT ADJUSTMENT DEVICE FOR MODEL SHIP

摘要

The purpose of the present invention is to provide a device which can enable quick and accurate setting of a draft condition of a model ship by means of an automated system without manually changing the position of a weight during a model test. In order to attain the purpose, the present invention provides an automatic draft adjustment device for a model ship, the automatic draft adjustment device comprising: a draft measurement apparatus which is provided on a model ship, measures the draft of the model ship, and transmits a measured draft value to a wireless transmission and reception apparatus; the wireless transmission and reception apparatus which is provided on the model ship, communicates wirelessly with a wireless adjustment apparatus, transmits the measured draft value from the draft measurement apparatus to the wireless adjustment apparatus, receives a gravity center changing command from the wireless adjustment apparatus, and transmits same to a gravity center changing apparatus; the wireless adjustment apparatus which is provided on the outside of the model ship and, if the measured draft value from the draft measurement apparatus is different from a pre-calculated set draft value, generates a gravity center changing command; and the gravity center changing apparatus which is provided on the model ship and, if the wireless adjustment apparatus generates the gravity center changing command, automatically changes the position of the gravity center of the model ship by means of the linear reciprocating motion of a weight.
