Abstract

The invention provides a foldable empennage spreading mechanism and a spreading method. The foldable empennage spreading mechanism does not need additional power, empennages are automatically spread only through the acceleration change of an aircraft during exiting from a chamber, thus the spreading mechanism is high in stability and reliable in property, and the space in a projectile body is saved, specifically, the foldable empennage spreading mechanism comprises the empennages, a sliding rod, a limiting mechanism, a sliding block, a main spring and a cabin shell; one sides of the bottom ends of the empennages are hinged to the cabin shell, and the other sides of the bottom ends of the empennages are connected with the sliding block; and when sliding along the sliding rod in the direction of a projectile head, the sliding block drives the empennages to rotate and stretch out of the shell, after the empennages reach predetermined positions, the sliding block is locked through the limiting mechanism, and the empennages are spread in place and locked.

Description

technical field [0001] The invention relates to a folding tail unfolding mechanism, which is a folding tail unfolding mechanism suitable for small precision guidance weapons, in particular to a folding tail unfolding mechanism and a unfolding method thereof. Background technique [0002] Folding tail is widely used in small precision-guided aircraft products. The tail is folded inside the cabin in a limited space, and the tail is unfolded after the aircraft launch meets certain conditions. The traditional method uses gas, electric motors or traditional springs as the driving force to deploy the folding tail. The actual situation has the following problems: [0003] (1) As the driving force of gas, electric signals need to be introduced, and the deployment power is large, which will cause great impact damage to the connection structure. In daily maintenance, the operator needs to take anti-static measures to prevent the gas from accidentally starting, causing damage to perso...
