Projectile comprising longitudinal devices for improving the hydrodynamic or aerodynamic lift and drag

摘要

According to one particular embodiment, the projectile according to the invention comprises a case 1 intended to contain a gas under pressure and an ejection nozzle 2. According to the invention, it furthermore comprises a series of elongate flexible elements in the form of tapes or of threads 3 extending backwards from the back part of the case 1. In the case of certain applications, particularly hydrodynamic ones, these tapes are extended along the body of the projectile so as to improve the adaptation of its movement to the environment. IMAGE
